Abstract : BACKGROUND: Lp-PLA2 is linked to cardiovascular diseases and poor outcomes, especially in diabetes, as it functions as a pro-inflammatory and oxidative mediator. OBJECTIVES: This research aimed to explore if there is a connection between the serum levels of Lp-PLA2 and the progression of coronary plaques (PP) in individuals with type 2 diabetes mellitus (T2DM) and those without the condition. MATERIALS AND METHODS: Serum Lp-PLA2 levels were measured in 137 T2DM patients with PP and 137 T2DM patients with no PP, and in 205 non-diabetic patients with PP and 205 non-diabetic patients with no PP. These individuals met the criteria for eligibility and underwent quantitative coronary angiography at the outset and again after about one year of follow-up. The attributes and parameters of the participants at the outset were recorded. RESULTS: Increased serum levels of Lp-PLA2 were closely associated with coronary artery PP, and also significantly correlated with change of MLD, change of diameter stenosis and change of cumulative coronary obstruction in both diabetic and non-diabetic groups, with higher correlation coefficients in diabetic patients as compared with non-diabetic patients. Moreover, multivariate logistic regression analysis showed that serum Lp-PLA2 level was an independent determinant of PP in both groups, with OR values more significant in diabetic patients than in non-diabetic patients. CONCLUSIONS: Levels of serum Lp-PLA2 show a significant association with the progression of coronary atherosclerotic plaque in patients with T2DM and those without, especially among individuals with diabetes.

Abstract : This work was developed to explore the versatility of thermophilic esterase for decolorizing raw molasses wastewater at high temperature and acidic pH. Combining covalent crosslinking method with deep eutectic solvent, a thermophilic esterase from Pyrobaculum calidifontis was immobilized on chitosan/macroporous resin composite carrier. The application of this immobilized thermophilic esterase eliminated 92.35% of colorants in raw molasses wastewater, achieving maximal decolorization efficiency across all the enzymes tested. Strikingly, this immobilized thermophilic esterase was capable of engaging in continuous activity for a 5-day period while removing 76.23% of pigments from samples. It effectively and continuously eliminated BOD(5) and COD, effectively and directly facilitating raw molasses wastewater decolorization under extreme conditions more readily than control group. In addition, this thermophilic esterase was believed to achieve decolorization through an addition reaction that disrupted conjugated system of melanoidins. Together, these results highlight an efficient and practical means of achieving enzyme-based molasses wastewater decolorization.

Abstract : Cholesterol metabolism in the brain plays a crucial role in normal physiological function, and its aberrations are associated with cognitive dysfunction. The present study aimed to determine which cholesterol-related genes play a vital role in cognitive dysfunction and to dissect its underlying molecular mechanisms using a systems genetics approach in the BXD mice family. We first systematically analyzed the association of expression of 280 hippocampal genes related to cholesterol metabolism with cognition-related traits and identified lipoprotein lipase (Lpl) as a critical regulator. This was further confirmed by phenome-wide association studies that indicate Lpl associated with hippocampus volume residuals and anxiety-related traits. By performing expression quantitative trait locus mapping, we demonstrate that Lpl is strongly cis-regulated in the BXD hippocampus. We also identified -3,300 genes significantly (p < 0.05) correlated with the Lpl expression. Those genes are mainly involved in the regulation of neuron-related traits through the MAPK signaling pathway, axon guidance, synaptic vesicle cycle, and NF-kappa B signaling pathway. Furthermore, a protein-protein interaction network analysis identified several direct interactors of Lpl, including Rab3a, Akt1, Igf1, Crp, and Lrp1, which indicates that Lpl involves in the regulation of cognitive dysfunction through Rab3a-mediated synaptic vesicle cycle and Akt1/Igf1/Crp/Lrp1-mediated MAPK signaling pathway. Our findings demonstrate the importance of the Lpl, among the cholesterol-related genes, in regulating cognitive dysfunction and highlighting the potential signaling pathways, which may serve as novel therapeutic targets for the treatment of cognitive dysfunction.

Abstract : Remdesivir (RDV), a phosphoramidate prodrug, has broad-spectrum antiviral activity. It is the first antiviral drug approved by the US Food and Drug Administration (FDA) for the treatment of COVID-19. RDV is rapidly metabolized in the body to produce derivatives: alanine metabolite (RM-442) and RDV C-nucleoside (RN). Here, phosphatase inhibitor PhosSTOP and carboxylesterase inhibitor 5,5'-dithiobis-2-nitrobenzoic acid were used to improve stability of RDV in mouse blood. We developed a rapid and sensitive LC-MS/MS method to simultaneously quantify RDV, RM-442 and RN in mouse blood. Chromatographic separation was achieved by gradient elution on an ACQUITY HSS T(3) column. The run time was 3.2 min. The linearity ranges of the analytes were 0.5-1000 ng/mL for RDV, 5-10000 ng/mL for both RM-442 and RN, respectively. The method had an acceptable precision (RSD < 8.4% for RDV, RSD < 10.7% for RM-442, and RSD < 7.2% for RN) and accuracy (91.0%-106.3% for RDV, 92.5%-98.6% for RM-442, and 87.5%-98.4% for RN). This method was successfully applied to analyze RDV, RM-442 and RN in blood of normal and diabetic nephropathy DBA/2J mice after intravenous injection of RDV 20 mg/kg. The AUC(0-t) of RN between the normal and diabetic nephropathy mice had significant difference (P < 0.01).

Title : Improved liver lipid catabolism and utilization in growth hormone transgenic common carp (Cyprinus carpio L.) through enhanced lipolytic and fatty acid beta-oxidation pathways - Wu_2022_Front.Endocrinol.(Lausanne)_13_982488

Abstract : Growth hormone (GH) transgenic common carp (Cyprinus carpio L.) show desirable aquaculture traits. Their specific growth rate (SGR) and feed efficiency (FE) are approximately 12% and 17% higher than the wild-type (WT) common carp, respectively. However, the mechanisms of lipid catabolism (lipolysis and fatty acid beta-oxidation) and utilization in GH transgenic common carp are still unclear. In this study, we firstly compared the lipid metabolism of GH transgenic (initial weight 3.72 +/- 0.32 g) and WT (initial weight 3.30 +/- 0.28 g) common carp fed with a normal fat level diet (6% lipid, 33% protein) for two months, then compared the growth performance of GH transgenic (initial weight 3.65 +/- 0.33 g) and WT (initial weight 3.27 +/- 0.26 g) common carp fed with different fat levels diets (6% lipid and 12% lipid, 33% protein) for two months. We found that the lipid content in serum, liver and whole body was significantly reduced in GH transgenic common carp, the hepatic activities of the lipolytic enzymes hormone-sensitive lipase and adipose triglyceride lipase were enhanced, and the hepatic expression level of hormone-sensitive lipase was upregulated. In addition, the mitochondrion numbers were increased, and the expression level of carnitine palmitoyltransferase-1a and carnitine palmitoyltransferase-1b was upregulated in the liver of GH transgenic common carp. GH transgenic common carp showed higher weight gain and SGR than that in WT carp when fed with a normal-fat diet as they did when fed with a high-fat diet, and GH transgenic common carp showed higher FE than that in WT carp when fed with a high-fat diet. These results suggested that the lipid catabolism and utilization was improved in the GH transgenic common carp liver through enhanced lipolytic and fatty acid beta-oxidation pathways. Our study provides new insights into improving lipid utilization in some aquaculture fish species.

Abstract : Powdery mildew resistance gene MlWE74, originated from wild emmer wheat accession G-748-M, was mapped in an NBS-LRR gene cluster of chromosome 2BS. Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is a globally devastating disease. Wild emmer wheat (Triticum turgidum var. dicoccoides) is a valuable genetic resource for improving disease resistance in common wheat. A powdery mildew resistance gene was transferred to hexaploid wheat line WE74 from wild emmer accession G-748-M. Genetic analysis revealed that the powdery mildew resistance in WE74 is controlled by a single dominant gene, herein temporarily designated MlWE74. Bulked segregant analysis (BSA) and molecular mapping delimited MlWE74 to the terminal region of chromosome 2BS flanking by markers WGGBD412 and WGGBH346 within a genetic interval of 0.25 cM and corresponding to 799.9 kb genomic region in the Zavitan reference sequence. Sequence annotation revealed two phosphoglycerate mutase-like genes, an alpha/beta-hydrolases gene, and five NBS-LRR disease resistance genes that could serve as candidates for map-based cloning of MlWE74. The geographical location analysis indicated that MlWE74 is mainly distributed in Rosh Pinna and Amirim regions, in the northern part of Israel, where environmental conditions are favorable to the occurrence of powdery mildew. Moreover, the co-segregated marker WGGBD425 is helpful in marker-assisted transfer of MlWE74 into elite cultivars.

Abstract : The emergence and perseverance of drug resistant strains of Mycobacterium tuberculosis (Mtb) ensures that drug discovery efforts remain at the forefront of tuberculosis research. There are numerous different approaches that can be employed to lead to the discovery of anti-tubercular agents. In this work, we endeavored to optimize the anthraquinone chemical scaffold of a known drug, rhein, converting it from a compound with negligible activity against Mtb, to a series of compounds with potent activity. Two compounds exhibited low toxicity and good liver microsome stability and were further progressed in attempts to identify the biological target. Whole genome sequencing of resistant isolates revealed inactivating mutations in a monoglyceride lipase. Over-expression trials and an enzyme assay confirmed that the designed compounds are prodrugs, activated by the monoglyceride lipase. We propose that rhein is the active moiety of the novel compounds, which requires chemical modifications to enable access to the cell through the extensive cell wall structure. This work demonstrates that re-engineering of existing antimicrobial agents is a valid method in the development of new anti-tubercular compounds.

Abstract : Background: The N-myc downstream-regulated gene (NDRG) family, NDRG1-4, has been involved in a wide spectrum of biological functions in multiple cancers. However, their prognostic values remain sparse in gastric cancer (GC). Therefore, it is crucial to systematically investigate the prognostic values of the NDRG family in GC. Methods: The prognostic values of the NDRG family were evaluated by Kaplan-Meier Plotter and SurvExpress. The mRNA of the NDRG family was investigated in The Cancer Genome Atlas (TCGA). Transcription factors (TFs) and miRNAs associated with the NDRG family were predicted by NetworkAnalysis. The prognostic values of DNA methylation levels were analyzed by MethSurv. The correlation between immune cells and the NDRG family was evaluated by the Tumor Immune Estimation Resource (TIMER) database. Results: High levels of mRNA expression of NDRG2 and NDRG3 were associated with a favorable prognosis in all GCs. In HER2 (-) GC, NDRG1 was significantly associated with a poor prognosis of GC [hazard ratio (HR) = 1.65, 95% confidence interval (CI) = 1.16-2.33, p = 0.0046]. In HER2 (+) GC, NDRG4 showed a poor prognosis (HR = 1.4, 95% CI: 1.06-1.85, p = 0.017). NDRG4 was an independent prognostic factor in recurrence-free survival by TCGA cohort. The low-risk NDRG-signature group displayed a significantly favorable survival outcome than the high-risk group (HR = 1.76, 95% CI: 1.2-2.59, p = 0.00385). The phosphorylated protein NDRG1 (NDRG1_pT346) displayed a favorable overall survival and was significantly associated with HER2 and phosphorylated HER2. Epidermis development was the top biological process (BP) for coexpressed genes associated with NDRG1 and NDRG4, while mitotic nuclear division and mitotic cell processes were the top BPs for NDRG2 and NDRG3, respectively. Overall, 6 CpGs of NDRG1, 4 CpGs of NDRG2, 3 CpGs of NDRG3 and 24 CpGs of NDRG4 were associated with significant prognosis. CD4(+) T-cells showed the highest correlation with NDRG4 (correlation = 0.341, p = 2.14e(-11)). Furthermore, BCL6 in follicular helper T-cells (Tfh) cells showed the highest association with NDRG4 (correlation = 0.438, p = 00e(+)00). Conclusions: This study analyzed the multilevel prognostic values and biological roles of the NDRG family in GC.

Abstract : Due to its complex pathogenesis, the prevention and therapization of Alzheimer's disease (AD) remains a serious challenge. Crocin, the main compound isolated from Crocus sativus L., demonstrates various pharmacological activities including antiapoptotic properties. The present study investigated the neuroprotective effect of crocin and the underlying mechanisms. In lglutamatedamaged HT22 cells, 3h crocin pretreatment strongly enhanced the HT22 cell viability, reduced the apoptotic rate, mitigated mitochondrial dysfunction, suppressed intracellular reactive oxygen species (ROS) accumulation and Ca2+ overload compared with untreated cells. Additionally, crocin significantly decreased the expression levels of Bax, Bad and cleaved caspase3 and increased the expression levels of Bcell lymphomaextra large, phosphorylated (P) protein kinase B and Pmammalian target of rapamycin compared with untreated cells. In mice with AD induced by dgalactose and aluminum trichloride, crocin substantially improved the cognition and memory abilities of the mice as measured by their coordination of movement in an open field test, and reduced their escape time in the Morris water maze test compared with untreated mice. Biochemical analysis confirmed that crocin was able to reduce the Abeta142 content in the mouse brains, increase the levels of glutathione peroxidase, superoxide dismutase, acetylcholine and choline acetyltransferase, and reduce the levels of ROS and acetylcholinesterase in the serum, cerebral cortex and hypothalamus compared with untreated mice. Immunohistochemical analysis demonstrated that crocin reduced Abeta142 deposition in the hippocampus of the brains of treated mice compared with untreated mice. In conclusion, crocin demonstrates good prospects in the treatment of AD through the oxidative stressassociated apoptosis signaling pathway.

Abstract : Banana cultivars (Musa ssp.) are diploid, triploid and tetraploid hybrids derived from Musa acuminata and Musa balbisiana. We presented a high-quality draft genome assembly of M. balbisiana with 430 Mb (87%) assembled into 11 chromosomes. We identified that the recent divergence of M. acuminata (A-genome) and M. balbisiana (B-genome) occurred after lineage-specific whole-genome duplication, and that the B-genome may be more sensitive to the fractionation process compared to the A-genome. Homoeologous exchanges occurred frequently between A- and B-subgenomes in allopolyploids. Genomic variation within progenitors resulted in functional divergence of subgenomes. Global homoeologue expression dominance occurred between subgenomes of the allotriploid. Gene families related to ethylene biosynthesis and starch metabolism exhibited significant expansion at the pathway level and wide homoeologue expression dominance in the B-subgenome of the allotriploid. The independent origin of 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) homoeologue gene pairs and tandem duplication-driven expansion of ACO genes in the B-subgenome contributed to rapid and major ethylene production post-harvest in allotriploid banana fruits. The findings of this study provide greater context for understanding fruit biology, and aid the development of tools for breeding optimal banana cultivars.

Abstract : Strigolactones, a class of plant hormones with multiple functions, mediate plant-plant and plant-microorganism communications in the rhizosphere. In this study, we developed potent strigolactone antagonists, which covalently bind to the strigolactone receptor D14, by preparing an array of triazole urea compounds. Using yeast two-hybrid and rice-tillering assays, we identified a triazole urea compound KK094 as a potent inhibitor of strigolactone receptors. Liquid chromatography-tandem mass spectrometry analysis and X-ray crystallography revealed that KK094 was hydrolyzed by D14, and that a reaction product of this degradation covalently binds to the Ser residue of the catalytic triad of D14. Furthermore, we identified two triazole urea compounds KK052 and KK073, whose effects on D14-D53/D14-SLR1 complex formation were opposite due to the absence (KK052) or presence (KK073) of a trifluoromethyl group on their phenyl ring. These results demonstrate that triazole urea compounds are potentially powerful tools for agricultural application and may be useful for the elucidation of the complicated mechanism underlying strigolactone perception.

Ref : J Biomed Nanotechnol , 14 :354 , 2018
Abstract : In this work, we developed an unexplored enzyme-responsive core-shell nanogel via the assembly of hydrogelators at the surface of silicon nanoparticles. The immobilized carboxylesterase at the surface of silicon nanoparticles can catalyse precursors into hydrogelators, self-assembling around the surface of silicon nanoparticles owing to its surface confinement effect. These novel phenomena can be confirmed by observation of their morphology and increased diameters through scanning electron microscopy, transmission electron microscopy and dynamic light scattering. Moreover, these resulting core-shell nanogels can achieve controlled growth of the gel layer by means of changing the concentrations of precursors. Because of their good biocompatibility, these nanogels can realize applications in enzyme-specific drug delivery as nanocarriers.

Title : Activation of Peroxisome Proliferator-Activated Receptor Gamma and Disruption of Progesterone Synthesis of 2-Ethylhexyl Diphenyl Phosphate in Human Placental Choriocarcinoma Cells: Comparison with Triphenyl Phosphate - Hu_2017_Environ.Sci.Technol_51_4061

Ref : Environ Sci Technol , 51 :4061 , 2017
Abstract : 2-Ethylhexyl diphenyl phosphate (EHDPP), an organophosphate flame retardant (OPFR), is frequently detected in human blood. In this study, the sensitive dual-luciferase reporter gene assay and molecular docking were used to investigate the activation of EHDPP to human peroxisome proliferator-activated receptor gamma (PPARG). Results show that EHDPP exhibited stronger PPARG activation (EC(20): 2.04 microM) than triphenyl phosphate (TPhP) (EC(20): 2.78 microM). EHDPP upregulated the gene expression of 3beta-hydroxysteroid dehydrogenase type 1 (3beta-HSD1) in human placental choriocarcinoma cells in a dose-dependent manner, and the lowest observable effective concentration was 10 microM, lower than that of TPhP (20 microM). EHDPP significantly altered progesterone secretion at a lower concentration (10 microM) than that of TPhP (20 microM), and both EHDPP and TPhP significantly promoted human chorionic gonadotropin (hCG) production at 20 microM. Furthermore, inactivation of PPARG by either a pharmacological inhibitor (GW9662) or small interfering RNA (siRNA) abolished the change in progesterone secretion and gene expression in the cells exposed to EHDPP, suggesting that the PPARG signaling pathway plays a role in the upregulation of progesterone by the two OPFRs. This is the first report to show that OPFRs can alter the biosynthesis of progesterone in the placenta, which could affect female reproduction and fetal development.

Title : Mono-2-ethylhexyl phthalate inhibits human extravillous trophoblast invasion via the PPARgamma pathway - Gao_2017_Toxicol.Appl.Pharmacol_327_23
Author(s) : Gao F , Hu W , Li Y , Shen H , Hu J
Ref : Toxicol Appl Pharmacol , 327 :23 , 2017
Abstract : Concerns over the adverse reproductive outcomes in human have been raised, more evidence including the underlying mechanism are required. Since extravillous trophoblast (EVT) invasion is an important physiological step during early development, the effects of mono-2-ethylhexyl phthalate (MEHP), the bioactive metabolite of DEHP, on EVT invasion were investigated using Matrigel-coated transwell chambers and cell line HTR-8/SVneo. In the transwell-based invasive assay, MEHP exposure inhibited EVT invasion as judged by decreased invasion index. Further analysis showed that MEHP exposure significantly inhibited the activity of matrix metalloproteinase-9 (MMP-9), which is an important positive regulator of EVT invasion. Meanwhile, the protein levels of tissue inhibitor matrix metalloproteinase-1 (TIMP-1), one key negative regulator of EVT invasion, were upregulated by MEHP treatment. Finally, inactivation of PPARgamma pathway by either PPARgamma inhibitors or PPARgamma shRNA knockdown rescued the MEHP-induced inhibited invasion of HTR-8/SVneo cells, which is accompanied by the recovery of inhibited MMP-9 expression. The present study provides the evidence that MEHP exposure inhibits trophoblast invasion via PPARgamma at concentrations comparable to those found in humans, which provides an insight in understanding the mechanisms of DEHP-associated early pregnancy loss.

Abstract : The association between lipoprotein-associated phospholipase A2 (Lp-PLA2) G994T gene polymorphism and the risk of ischemic stroke is unclear. The aim of this study is to investigate the influence of Lp-PLA2 G994T genetic variant on the pathogenesis of ischemic stroke in Chinese population. A total of 348 patients with a clinical diagnosis of ischemic stroke and 260 gender-matched control subjects under physical examination were recruited from hospitals and genotyped for G994T gene polymorphism. The results showed that there was a significant difference in the genotype distribution between the two groups and people with GT or TT genotype were associated with the higher risk of ischemic stroke even after adjusting the effects of potential confounding factors. In addition, both ischemic stroke patients and control subjects carrying T allele showed relatively lower Lp-PLA2 activity and higher oxLDL level. Therefore, Lp-PLA2 G994T gene polymorphism may be an independent risk factor of ischemic stroke in Chinese population.

Abstract : Proteins, as executives of genes' instructions, are responsible for cellular phenotypes. Integratingproteomics with gene microarray, we conducted this study to identify potential protein biomarkers of colorectal cancer (CRC). Isobaric tags with related and absolute quantitation (iTRAQ) labeling mass spectrometry (MS) was applied to screen and identify differentially expressed proteins between paired CRC and adjacent normal mucosa. Meanwhile, Affymetrix U133plus2.0 microarrays were used to perform gene microarray analysis. Verification experiments included immunohistochemistry (IHC), western blot and enzyme-linked immunosorbent assay (ELISA) of selected proteins. Overall, 5469 differentially expressed proteins were detected with iTRAQ-MS from 24 matched CRC and adjacent normal tissues. And gene microarray identified 39859 differential genes from 52 patients. Of these, 3083 differential proteins had corresponding differentially expressed genes, with 245 proteins and their genes showed >1.5-fold change in expression level. Gene ontology enrichment analysis revealed that up-regulated proteins were more involved in cell adhesion and motion than down-regulated proteins. In addition, up-regulated proteins were more likely to be located in nucleus and vesicles. Further verification experiments with IHC confirmed differential expression levels of 5 proteins (S100 calcium-binding protein A9, annexin A3, nicotinamide phosphoribosyltransferase, carboxylesterase 2 and calcium activated chloride channel A1) between CRC and normal tissues. Besides, western blot showed a stepwise increase of annexin A3 abundance in normal colorectal mucosa, adenoma and CRC tissues. ELISAresults revealed significantly higher serum levels of S100 calcium-binding protein A9 and annexin A3 in CRC patients than healthy controls, validating diagnostic value of these proteins. Cell experiments showed that inhibition of annexin A3 could suppress CRC cell proliferation and aggressiveness. S100 calcium-binding protein A9, annexin A3, nicotinamide phosphoribosyltransferase, carboxylesterase 2 and calcium activated chloride channel A1 were probably potential biomarkers of colorectal cancer. Annexin A3 was a potentially valuable therapeutic target of CRC.

Abstract : Analyses of genome-wide association study (GWAS) data have revealed that detectable genetic mosaicism involving large (>2 Mb) structural autosomal alterations occurs in a fraction of individuals. We present results for a set of 24,849 genotyped individuals (total GWAS set II [TGSII]) in whom 341 large autosomal abnormalities were observed in 168 (0.68%) individuals. Merging data from the new TGSII set with data from two prior reports (the Gene-Environment Association Studies and the total GWAS set I) generated a large dataset of 127,179 individuals; we then conducted a meta-analysis to investigate the patterns of detectable autosomal mosaicism (n = 1,315 events in 925 [0.73%] individuals). Restricting to events >2 Mb in size, we observed an increase in event frequency as event size decreased. The combined results underscore that the rate of detectable mosaicism increases with age (p value = 5.5 x 10(-31)) and is higher in men (p value = 0.002) but lower in participants of African ancestry (p value = 0.003). In a subset of 47 individuals from whom serial samples were collected up to 6 years apart, complex changes were noted over time and showed an overall increase in the proportion of mosaic cells as age increased. Our large combined sample allowed for a unique ability to characterize detectable genetic mosaicism involving large structural events and strengthens the emerging evidence of non-random erosion of the genome in the aging population.

Abstract : The regulation of lipid metabolism is complex, and is currently an extensive area of research. In this study, the partial sequences of 15 genes involved in lipid metabolism were cloned from the liver of Synechogobius hasta, including g6pd, 6pgd, me, icdh, fas, acc-alpha, acc-beta, lpl, atgl, hsla, hslb, cpt 1a, srebp-1, ppar-alpha, and ppar-gamma. Phylogenetic analysis further identified these genes, and confirmed the classification and evolutionary status of S. hasta. mRNA of all genes was detected in the liver, spleen, muscle, gill, brain, intestine, and heart, but at varying levels. Practical applications: Excessive fat accumulation and disordered lipid metabolism have become serious problems in the sustainable and healthy development of aquaculture. The present study facilitates studies on the regulation of lipid metabolism at the molecular level in fish. The tissue expression profiles of genes increase our understanding of their physiological roles.

Title : Hepatic cholesteryl ester accumulation in lysosomal acid lipase deficiency: non-invasive identification and treatment monitoring by magnetic resonance - Thelwall_2013_J.Hepatol_59_543

Ref : Journal of Hepatology , 59 :543 , 2013
Abstract : BACKGROUND & AIMS: Lysosomal Acid Lipase (LAL) deficiency is a rare metabolic storage disease, caused by a marked reduction in activity of LAL, which leads to accumulation of cholesteryl esters (CE) and triglycerides (TG) in lysosomes in many tissues. We used (1)H magnetic resonance (MR) spectroscopy to characterize the abnormalities in hepatic lipid content and composition in patients with LAL deficiency, and in ex vivo liver tissue from a LAL deficiency rat model. Secondly, we used MR spectroscopy to monitor the effects of an enzyme replacement therapy (ERT), sebelipase alfa (a recombinant human lysosomal acid lipase), on hepatic TG and CE content in the preclinical model.
METHODS: Human studies employed cohorts of LAL-deficient patients and NAFLD subjects. Rat experimental groups comprised ex vivo liver samples of wild type, NAFLD, LAL-deficient, and LAL-deficient rats receiving 4weeks of sebelipase alfa treatment. Hepatic (1)H MR spectroscopy was performed using 3T (human) and 7T (preclinical) MRI scanners to quantify hepatic cholesterol and triglyceride content.
RESULTS: CE accumulation was identified in LAL deficiency in both human and preclinical studies. A significant decrease in hepatic CE was observed in LAL-deficient rats following treatment with sebelipase alfa.
CONCLUSIONS: We demonstrate an entirely non-invasive method to identify and quantify the hepatic lipid signature associated with a rare genetic cause of fatty liver. The approach provides a more favorable alternative to repeated biopsy sampling for diagnosis and disease progression / treatment monitoring of patients with LAL deficiency and other disorders characterised by increased free cholesterol and/or cholesteryl esters.

Abstract : Complex environmental conditions can significantly affect bacterial genome size by unknown mechanisms. The So0157-2 strain of Sorangium cellulosum is an alkaline-adaptive epothilone producer that grows across a wide pH range. Here, we show that the genome of this strain is 14,782,125 base pairs, 1.75-megabases larger than the largest bacterial genome from S. cellulosum reported previously. The total 11,599 coding sequences (CDSs) include massive duplications and horizontally transferred genes, regulated by lots of protein kinases, sigma factors and related transcriptional regulation co-factors, providing the So0157-2 strain abundant resources and flexibility for ecological adaptation. The comparative transcriptomics approach, which detected 90.7% of the total CDSs, not only demonstrates complex expression patterns under varying environmental conditions but also suggests an alkaline-improved pathway of the insertion and duplication, which has been genetically testified, in this strain. These results provide insights into and a paradigm for how environmental conditions can affect bacterial genome expansion.

Title : t-AUCB, an improved sEH inhibitor, suppresses human glioblastoma cell growth by activating NF-kappaB-p65 - Li_2012_J.Neurooncol_108_385

Abstract : Although sEH inhibitors are well studied in inflammatory and cardiovascular diseases, their effects on gliomas are unclear. In this study, we investigated the effects of t-AUCB, a more potent and selective sEH inhibitor, on U251 and U87 human glioblastoma cell lines and the HepG2 human hepatocellular carcinoma cell line. Our results showed that t-AUCB efficiently inhibited sEH activities in all three cell lines (the inhibition rate was more than 80% in each) and suppressed U251 and U87 cell growth in a dose-dependent manner, but exhibited no cell growth inhibition on HepG2. We detected high levels of phosphorylated NF-kappaB-p65 (Ser536) in t-AUCB-treated U251 and U87 cells, and then found that the NF-kappaB inhibitor PDTC can completely abolish t-AUCB-induced growth inhibition. This indicated that t-AUCB suppresses U251 and U87 cell growth by activating NF-kappaB-p65. Moreover, we found that t-AUCB induces cell-cycle G0/G1 phase arrest by regulating Cyclin D1 mRNA and protein levels and CDC2 (Thr161) phosphorylation level. We propose to further test this promising reagent for its anti-glioma activity in clinical relevant orthotopic brain glioma models.

Title : The apoptosis-resistance in t-AUCB-treated glioblastoma cells depends on activation of Hsp27 - Li_2012_J.Neurooncol_110_187
Author(s) : Li J , Hu W , Lan Q
Ref : J Neurooncol , 110 :187 , 2012
Abstract : We previously reported that sEH inhibitor t-AUCB suppresses the growth of human glioblastoma U251 and U87 cell lines and induces cell-cycle G0/G1 phase arrest. In present study, we found even 96 h-treatment of 200 muM t-AUCB can not induce apoptosis in U251 and U87 cells. We also revealed that 200 muM t-AUCB significantly elevates the activation of p38 MAPK, MAPKAPK2 and Hsp27. The p38 MAPK inhibitor SB203580 and the inhibitor of Hsp27 phosphorylation, KRIBB3, were used to investigate the mechanism of the apoptosis-resistance. The results showed that, after blocking the activation of Hsp27 by SB203580 or KRIBB3, 200 muM t-AUCB significantly induces apoptosis and increases caspase-3 activities in U251 and U87 cells. Our data demonstrated that t-AUCB induces cell apoptosis after blocking itself-induced activation of Hsp27, and that the activation of Hsp27 may confer chemoresistance in GBM cells. The combination of t-AUCB and the inhibitor of Hsp27 phosphorylation may be a potential strategy for treatment of glioblastoma.

Abstract : We previously reported a highly potent DPP-IV inhibitor 6 with low in vivo efficacy. While trying to maintain consistent in vitro and in vivo biological activity, we initiated a pharmacokinetic property-driven optimization to improve the metabolic stability and permeability of inhibitor 6. A simple scaffold replacement of thienopyrimidine with pyrrolopyrimidine (21a) led to significantly improved metabolic stability (4% vs. 65% remaining). Further modification of the pyrrolopyrimidine scaffold to produce compound 21j resulted in much better oral bioavailability than 6. Importantly, compound 21j exhibits greater in vivo efficacy than does 6 and Alogliptin and is worthy of further development.

Abstract : Using next-generation sequencing technology alone, we have successfully generated and assembled a draft sequence of the giant panda genome. The assembled contigs (2.25 gigabases (Gb)) cover approximately 94% of the whole genome, and the remaining gaps (0.05 Gb) seem to contain carnivore-specific repeats and tandem repeats. Comparisons with the dog and human showed that the panda genome has a lower divergence rate. The assessment of panda genes potentially underlying some of its unique traits indicated that its bamboo diet might be more dependent on its gut microbiome than its own genetic composition. We also identified more than 2.7 million heterozygous single nucleotide polymorphisms in the diploid genome. Our data and analyses provide a foundation for promoting mammalian genetic research, and demonstrate the feasibility for using next-generation sequencing technologies for accurate, cost-effective and rapid de novo assembly of large eukaryotic genomes.

Abstract : Schistosomiasis remains a serious public health problem with an estimated 200 million people infected in 76 countries. Here we isolated ~ 8,400 potential protein-encoding cDNA contigs from Schistosoma japonicum after sequencing circa 84,000 expressed sequence tags. In tandem, we undertook a high-throughput proteomics approach to characterize the protein expression profiles of a number of developmental stages (cercariae, hepatic schistosomula, female and male adults, eggs, and miracidia) and tissues at the host-parasite interface (eggshell and tegument) by interrogating the protein database deduced from the contigs. Comparative analysis of these transcriptomic and proteomic data, the latter including 3,260 proteins with putative identities, revealed differential expression of genes among the various developmental stages and sexes of S. japonicum and localization of putative secretory and membrane antigens, enzymes, and other gene products on the adult tegument and eggshell, many of which displayed genetic polymorphisms. Numerous S. japonicum genes exhibited high levels of identity with those of their mammalian hosts, whereas many others appeared to be conserved only across the genus Schistosoma or Phylum Platyhelminthes. These findings are expected to provide new insights into the pathophysiology of schistosomiasis and for the development of improved interventions for disease control and will facilitate a more fundamental understanding of schistosome biology, evolution, and the host-parasite interplay.

Abstract : We report improved whole-genome shotgun sequences for the genomes of indica and japonica rice, both with multimegabase contiguity, or almost 1,000-fold improvement over the drafts of 2002. Tested against a nonredundant collection of 19,079 full-length cDNAs, 97.7% of the genes are aligned, without fragmentation, to the mapped super-scaffolds of one or the other genome. We introduce a gene identification procedure for plants that does not rely on similarity to known genes to remove erroneous predictions resulting from transposable elements. Using the available EST data to adjust for residual errors in the predictions, the estimated gene count is at least 38,000-40,000. Only 2%-3% of the genes are unique to any one subspecies, comparable to the amount of sequence that might still be missing. Despite this lack of variation in gene content, there is enormous variation in the intergenic regions. At least a quarter of the two sequences could not be aligned, and where they could be aligned, single nucleotide polymorphism (SNP) rates varied from as little as 3.0 SNP/kb in the coding regions to 27.6 SNP/kb in the transposable elements. A more inclusive new approach for analyzing duplication history is introduced here. It reveals an ancient whole-genome duplication, a recent segmental duplication on Chromosomes 11 and 12, and massive ongoing individual gene duplications. We find 18 distinct pairs of duplicated segments that cover 65.7% of the genome; 17 of these pairs date back to a common time before the divergence of the grasses. More important, ongoing individual gene duplications provide a never-ending source of raw material for gene genesis and are major contributors to the differences between members of the grass family.

Title : Amyloid-beta increases acetylcholinesterase expression in neuroblastoma cells by reducing enzyme degradation - Hu_2003_J.Neurochem_86_470

Abstract : Amyloid-beta (Abeta) is the principal protein constituent of 'senile plaques' and is a suspected mediator in Alzheimer's disease (AD). Senile plaques also contain acetylcholinesterase (AChE; EC 3.1.1.7), which may have a role in promoting Alphabeta-toxicity. We have found that Alphabeta can affect AChE expression in a neuron-like line, the N1E.115 neuroblastoma cell. When 1 micro mAlphabeta 1-42 or 25-35 was added for 24 h to differentiating N1E.115 in culture, AChE activity increased 30-40% in adherent cells, and 100% or more in nonadherent cells. The changes in both tetrameric (G4) and monomeric (G1) AChE forms were comparable. Turnover studies indicated that the elevation of AChE activity reflected slowed AChE degradation rather than accelerated synthesis. With a similar time course, Alphabeta also increased the quantity of muscarinic receptors on the plasma membrane. Immunocytochemistry for a lysosomal membrane protein (LAMP-1) indicated no change in abundance or localization of lysosomes in treated cells. But decreased labeling by pH-sensitive fluorescent dye pointed to an impairment of lysosomal acidification. We consider that the alteration of AChE expression after Alphabeta-exposure could reflect lysosomal dysfunction, and might itself enhance Alphabeta-toxicity.

Title : Evolutionary and biomedical implications of a Schistosoma japonicum complementary DNA resource - Hu_2003_Nat.Genet_35_139

Abstract : Schistosoma japonicum causes schistosomiasis in humans and livestock in the Asia-Pacific region. Knowledge of the genome of this parasite should improve understanding of schistosome-host interactions, biomedical aspects of schistosomiasis and invertebrate evolution. We assigned 43,707 expressed sequence tags (ESTs) derived from adult S. japonicum and their eggs to 13,131 gene clusters. Of these, 35% shared no similarity with known genes and 75% had not been reported previously in schistosomes. Notably, S. japonicum encoded mammalian-like receptors for insulin, progesterone, cytokines and neuropeptides, suggesting that host hormones, or endogenous parasite homologs, could orchestrate schistosome development and maturation and that schistosomes modulate anti-parasite immune responses through inhibitors, molecular mimicry and other evasion strategies.

Ref : Zhonghua Yi Xue Yi Chuan Xue Za Zhi , 16 :233 , 1999
Abstract : OBJECTIVE: To investigate the gene mutation of lipoprotein lipase(LPL) of familial LPL deficiency in China.
METHODS: The DNA sequencing of LPL gene of the patients was performed with the dideoxy method based on the polymerase chain reaction amplification using the genomic DNA as a template.
RESULTS: It was identified that a missense mutation in exon 6 of LPL gene (6G(979)-->A) resulted in the substitution of Glu(242) by Lys in a heterozygous state. CONCLUSION: The missense mutation of LPL may play a key role in the decrease of LPL activity. This is the first report about the gene mutation of LPL at this site in familial LPL deficiency. Moreover, it contributes to the elucidation of the pathophysiological mechanisms of atherosclerosis and some metabolic diseases.
