It affects the polarization of macrophages and the balance of related immune cell subpopulations, but the specific mechanism is still unclear. It has been found that silent information regulator 1 (SIRT1) is closely related to macrophage activity. The purpose of this study is to explore the mechanism of MG intervening in macrophage polarization during treatment of early adjuvant-induced (AIA) rats through the CAP-SIRT1 pathway. METHODS: We investigated the polarization of M1 macrophages and the differentiation of Th1 in AIA rats by flow cytometry. Activity of acetylcholinesterase (AChE) and the level of nicotinic adenine dinucleotide (NAD+) in serum were also detected, and immunohistochemical was used to detect the levels of alpha7 nicotinic cholinergic receptor (alpha7nAChR) and SIRT1. Then in macrophages, the molecular mechanism of MG regulating the abnormal activation of macrophages in rats with early AIA through the CAP-SIRT1 pathway was studied. RESULTS: MG can significantly inhibit the polarization of M1 macrophages and the differentiation of Th1 in AIA rats in the acute phase of inflammation. MG can significantly inhibit the activity of AChE and increase the level of NAD+, thereby further up-regulated the expression levels of alpha7nAChR and SIRT1. Meanwhile, MG inhibited nuclear factor-kappaB (NF-kappaB)-mediated inflammation by activating the CAP-SIRT1 pathway in macrophages. CONCLUSION: In summary, the stimulation of MG induced CAP activation, which up-regulated SIRT1 signal, and thereby inhibited M1 polarization through the NF-kappaB pathway, and improved the pathological immune environment of early-stage AIA rats. Title: Toxicity of gabapentin-lactam on the early developmental stage of zebrafish (Danio rerio) He Y, Jia D, Du S, Zhu R, Zhou W, Pan S, Zhang Y Ref: Environ Pollut, 287:117649, 2021 : PubMed ESTHER: He_2021_Environ.Pollut_287_117649 PubMedSearch: He 2021 Environ.Pollut 287 117649 PubMedID: 34182397 Abstract Gabapentin-lactam (GBP-L) is a transformation product (TP) of gabapentin (GBP), a widely used anti-epileptic pharmaceutical. Due to its high persistence, GBP-L has been frequently detected in the surface water. However, the effects of GBP-L on aquatic organisms have not been thoroughly investigated. In the present study, zebrafish (Danio rerio) embryos as a model organism were used to study the impacts of GBP-L in terms of embryos LC(50), spontaneous movement at 24 hpf (hours post fertilization), heartbeat rates at 48 hpf, and body length at 72 hpf, with the concentrations of GBP-L down to 0.01 microg/L, covering its environmental concentrations. Various biomarkers from nervous, antioxidant and immune systems of zebrafish larvae were analyzed, including acetylcholinesterase, acetylcholine, dopamine, gamma-aminobutyric acid, superoxide dismutase, catalase, glutathione S-transferase, C reactive protein, and lysozyme, to assess its toxicity on these systems. RT-qPCR was then used to further verify the results and explain the toxicological mechanism at the gene level. The results demonstrated that GBP-L is much more toxic than its parent compound, and could lead to adverse impacts on the aquatic organisms even at every low concentrations. Title: Hyperbaric oxygen therapy may be effective to improve hypoxemia in patients with severe COVID-2019 pneumonia: two case reports Guo D, Pan S, Wang M, Guo Y Ref: Undersea Hyperb Med, 47:181, 2020 : PubMed ESTHER: Guo_2020_Undersea.Hyperb.Med_47_181 PubMedSearch: Guo 2020 Undersea.Hyperb.Med 47 181 PubMedID: 32574433 Abstract Objectives: To determine whether hyperbaric oxygen (HBO2) therapy be effective to improve hypoxemia for severe COVID-19 pneumonia patients.

Here we optimized the GRAB(ACh) (GPCR-activation-based ACh) sensor to achieve substantially improved sensitivity in ACh detection, as well as reduced downstream coupling to intracellular pathways. The improved version of the ACh sensor retains the subsecond response kinetics, physiologically relevant affinity and precise molecular specificity for ACh of its predecessor. Using this sensor, we revealed compartmental ACh signals in the olfactory center of transgenic flies in response to external stimuli including odor and body shock. Using fiber photometry recording and two-photon imaging, our ACh sensor also enabled sensitive detection of single-trial ACh dynamics in multiple brain regions in mice performing a variety of behaviors. Title: Activation of cholinergic anti-inflammatory pathway involved in therapeutic actions of alpha-mangostin on lipopolysaccharide-induced acute lung injury in rats Yang Z, Yin Q, Olatunji OJ, Li Y, Pan S, Wang DD, Zuo J Ref: Int J Immunopathol Pharmacol, 34:2058738420954941, 2020 : PubMed ESTHER: Yang_2020_Int.J.Immunopathol.Pharmacol_34_2058738420954941 PubMedSearch: Yang 2020 Int.J.Immunopathol.Pharmacol 34 2058738420954941 PubMedID: 32886564 Abstract INTRODUCTION: Alpha-mangostin (MAN) possesses a wide variety of pharmacological effects. In this study, we investigated its effect on cholinergic anti-inflammatory pathway (CAP), and tested if CAP regulation was involved in the therapeutic action on acute lung injury (ALI). METHODS: Male Sprague Dawley rats were pre-treated with MAN (40 mg/kg) for 3 days and ALI was induced with an intraperitoneal injection of lipopolysaccharide (LPS). Certain rats received monolateral vagotomy or sham surgery. The effects on inflammatory reactions and relevant pathways in ALI rats or LPS pre-treated RAW 264.7 cells were investigated by histological, immunohistochemical, immunoblotting, RT-qPCR, and immunofluorescence assays, while levels of proinflammatory cytokines, acetylcholine (Ach) and the enzymatic activity of acetylcholinesterase (AchE) were determined by corresponding quantitative kits. RESULTS: Oral administration of MAN reduced the severity of ALI, while vagotomy surgery antagonized this effect. MAN restored the decline in alpha7 nicotinic acetylcholine receptor (alpha7nAchR) in the lungs of ALI rats, and promoted the expression of alpha7nAchR and choline acetyltransferase (CHAT) in RAW 264.7 cells. Although AchE expression was barely affected by MAN at 5 mug/ml, its catalytic activity was reduced by almost 95%. Extracellular rather than intracellular Ach was notably raised shortly after MAN treatment. Furthermore, MAN at 5 mug/ml effectively inhibited LPS-induced increase in phosphorylation and nucleus translocation of p65 subunit, and secretion of TNF-alpha and IL-1beta, which was then offset by methyllycaconitine citrate hydrate. CONCLUSION: MAN activated CAP by increasing peripheral Ach and up-regulating alpha7nAchR expression, which eventually led to NF-kappaB inhibition and remission of acute inflammations. Title: Activation of Cholinergic Anti-Inflammatory Pathway in Peripheral Immune Cells Involved in Therapeutic Actions of alpha-Mangostin on Collagen-Induced Arthritis in Rats Yin Q, Wu YJ, Pan S, Wang DD, Tao MQ, Pei WY, Zuo J Ref: Drug Des Devel Ther, 14:1983, 2020 : PubMed ESTHER: Yin_2020_Drug.Des.Devel.Ther_14_1983 PubMedSearch: Yin 2020 Drug.Des.Devel.Ther 14 1983 PubMedID: 32546965 Abstract Background: Studies have shown that alpha-mangostin (MG) could exert anti-rheumatic effects in vivo by restoring immunity homeostasis, and have indicated that activation of the choline anti-inflammatory pathway (CAP) may contribute to this immunomodulatory property. The current study was designed to further investigate the effects of MG on the CAP in peripheral immune cells and clarify its relevance to the potential anti-rheumatic actions. Methods: The catalytic activity of acetylcholinesterase (AChE) and expression of alpha7-nicotinic cholinergic receptor (alpha7nAChR) in peripheral blood mononuclear cells (PBMCs) from rats with collagen-induced arthritis (CIA) or human volunteers were evaluated after MG treatment. Consequent influences on the immune environment were assessed by flow cytometry and ELISA analyses. Indirect effects on joints resulting from these immune changes were studied in a co-culture system comprised of fibroblast-like synoviocytes (FLSs) and PBMCs. Results: MG promoted alpha7nAChR expression in PBMCs both in vivo and in vitro, and inhibited the enzymatic activity of AChE simultaneously. Activation of the CAP was accompanied by a significant decrease in Th17 cells (CD4(+)IL-17A(+)), while no obvious changes concerning the distribution of other T-cell subsets were noticed upon MG treatment. Meanwhile, MG decreased the secretion of TNF-alpha and IL-1beta under inflammatory conditions. PBMCs from MG-treated CIA rats lost the potential to stimulate NF-kappaB activation and pro-inflammatory cytokine production of FLSs in the co-culture system. Conclusion: Overall, the evidence suggested that MG can improve the peripheral immune milieu in CIA rats by suppressing Th17-cell differentiation through CAP activation, and achieve remission of inflammation mediated by FLSs. Title: Thiol-ene click reaction-induced fluorescence enhancement by altering the radiative rate for assaying butyrylcholinesterase activity Chen G, Feng H, Xi W, Xu J, Pan S, Qian Z Ref: Analyst, 144:559, 2019 : PubMed ESTHER: Chen_2019_Analyst_144_559 PubMedSearch: Chen 2019 Analyst 144 559 PubMedID: 30417195 Abstract Butyrylcholinesterase (BChE) generally acts as an important plasma biomarker for clinical diagnosis due to its major contribution to human plasma cholinesterase levels, but its current fluorometric assay relying on fluorogenic substrates frequently suffers from the lack of sufficiently fast response time and specific recognition of substrates relative to the traditional Ellman's method. In this work, we report a fluorescent molecular probe for assaying BChE activity based on thiol-triggered fluorescence enhancement via thiol-ene click reactions. A low-temperature experiment and theoretical analysis exclude the possibility of weak fluorescence of the probe caused by an intramolecular photoinduced electron transfer process and support the main cause of an ultraslow radiative rate due to the introduction of two acrylyl groups. This probe has sensitive fluorescence responses to thiols via thiol-ene click chemistry, and it can distinguish between glutathione and cysteine or homocysteine in different emission colors. The rapid reaction kinetics of this probe enables it to monitor hydrolysis reactions catalyzed by butyrylcholinesterase (BChE) in a real-time manner. This probe is used to develop the first fluorometric assay of BChE activity based on fluorescence enhancement triggered by thiol-ene click chemistry using butyrylthiocholine as the substrate. The established BChE assay shows excellent sensitivity, and is capable of avoiding the interference from glutathione and acetylcholinesterase (AChE) in a complex matrix. The inhibition test of tacrine on BChE with this assay substantiates its feasibility in screening potential inhibitors of BChE. This work demonstrates a design strategy of fluorescent probes lighted up by thiol-ene click reactions, reveals the main cause of thiol-triggered fluorescence enhancement by altering the radiative rate, and provides the first fluorometric assay of BChE based on rapid thiol-ene click reactions. Title: Redox-Controlled Fluorescent Nanoswitch Based on Reversible Disulfide and Its Application in Butyrylcholinesterase Activity Assay Chen G, Feng H, Jiang X, Xu J, Pan S, Qian Z Ref: Analytical Chemistry, 90:1643, 2018 : PubMed ESTHER: Chen_2018_Anal.Chem_90_1643 PubMedSearch: Chen 2018 Anal.Chem 90 1643 PubMedID: 29298486 Abstract Butyrylcholinesterase (BChE) mainly contributing to plasma cholinesterase activity is an important indicator for routinely diagnosing liver function and organophosphorus poisoning in clinical diagnosis, but its current assays are scarce and frequently suffer from some significant interference and instability. Herein, we report a redox-controlled fluorescence nanoswtich based on reversible disulfide bonds, and further develop a fluorometric assay of BChE via thiol-triggered disaggregation-induced emission. Thiol-functionalized carbon quantum dots (thiol-CQDs) with intense fluorescence is found to be responsive to hydrogen peroxide, and their redox reaction transforms thiol-CQDs to nonfluorescent thiol-CQD assembly. The thiols inverse this process by a thiol-exchange reaction to turn on the fluorescence. The fluorescence can be reversibly switched by the formation and breaking of disulfide bonds caused by external redox stimuli. The specific thiol-triggered disaggregation-induced emission enables us to assay BChE activity in a fluorescence turn-on and real-time way using butyrylthiocholine iodide as the substrate. As-established BChE assay achieves sufficient sensitivity for practical determination in human serum, and is capable of avoiding the interference from micromolar glutathione and discriminatively quantifying BChE from its sister enzyme acetylcholinesterase. The first design of reversible redox-controlled nanosiwtch based on disulfide expands the application of disulfide chemistry in sensing and clinical diagnostics, and this novel BChE assay enriches the detection methods for cholinesterase activity. Title: The Synergistic Effect of Microwave Radiation and Hypergravity on Rats and the Intervention Effect of Rana Sylvatica Le Conte Oil Sun W, Yang Y, Yu H, Wang L, Pan S Ref: Dose Response, 15:1559325817711511, 2017 : PubMed ESTHER: Sun_2017_Dose.Response_15_1559325817711511 PubMedSearch: Sun 2017 Dose.Response 15 1559325817711511 PubMedID: 28717348 Abstract AIM: The phenomena of hypergravity and microwave radiation are widespread, which cause more and more concern for the hazards to human health. The aim of this study was to investigate the synergistic effect of microwave radiation and hypergravity on rats and observe the protective effect of Rana sylvatica Le conte oil.

Comparison between yak and the closely related low-altitude cattle (Bos taurus) is informative in studying animal adaptation to high altitude. Here, we present the draft genome sequence of a female domestic yak generated using Illumina-based technology at 65-fold coverage. Genomic comparisons between yak and cattle identify an expansion in yak of gene families related to sensory perception and energy metabolism, as well as an enrichment of protein domains involved in sensing the extracellular environment and hypoxic stress. Positively selected and rapidly evolving genes in the yak lineage are also found to be significantly enriched in functional categories and pathways related to hypoxia and nutrition metabolism. These findings may have important implications for understanding adaptation to high altitude in other animal species and for hypoxia-related diseases in humans.

Here we present a draft genomic sequence of the CHO-K1 ancestral cell line. The assembly comprises 2.45 Gb of genomic sequence, with 24,383 predicted genes. We associate most of the assembled scaffolds with 21 chromosomes isolated by microfluidics to identify chromosomal locations of genes. Furthermore, we investigate genes involved in glycosylation, which affect therapeutic protein quality, and viral susceptibility genes, which are relevant to cell engineering and regulatory concerns. Homologs of most human glycosylation-associated genes are present in the CHO-K1 genome, although 141 of these homologs are not expressed under exponential growth conditions. Many important viral entry genes are also present in the genome but not expressed, which may explain the unusual viral resistance property of CHO cell lines. We discuss how the availability of this genome sequence may facilitate genome-scale science for the optimization of biopharmaceutical protein production.

It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression. Here we use a homozygous doubled-monoploid potato clone to sequence and assemble 86% of the 844-megabase genome. We predict 39,031 protein-coding genes and present evidence for at least two genome duplication events indicative of a palaeopolyploid origin. As the first genome sequence of an asterid, the potato genome reveals 2,642 genes specific to this large angiosperm clade. We also sequenced a heterozygous diploid clone and show that gene presence/absence variants and other potentially deleterious mutations occur frequently and are a likely cause of inbreeding depression. Gene family expansion, tissue-specific expression and recruitment of genes to new pathways contributed to the evolution of tuber development. The potato genome sequence provides a platform for genetic improvement of this vital crop. Title: Esterification activity and conformation studies of Burkholderia cepacia lipase in conventional organic solvents, ionic liquids and their co-solvent mixture media Pan S, Liu X, Xie Y, Yi Y, Li C, Yan Y, Liu Y Ref: Bioresour Technol, 101:9822, 2010 : PubMed ESTHER: Pan_2010_Bioresour.Technol_101_9822 PubMedSearch: Pan 2010 Bioresour.Technol 101 9822 PubMedID: 20713309 Abstract In this work, experiments were carried out to evaluate the esterification activity and conformation of lipase from Burkholderia cepacia in the selected conventional organic solvents, ionic liquids and their co-solvent mixture media. The results revealed that the activity of esterification of B. cepacia lipase was mostly highest in co-solvent mixture of ionic liquids-organic solvents, followed by conventional organic solvents and ionic liquids. Hence, co-solvent mixture was a high-effective strategy to enhance the activity of B. cepacia lipase for non-aqueous enzymology reaction. Conformational studies via circular dichroism spectroscopy indicated that the secondary structure of B. cepacia lipase was variant in the above-mentioned media, especially the content of alpha-helix, which was probably responsible for lipase activity difference.

Title: Hepatic lipase gene -514C/T polymorphism in the Guangxi Hei Yi Zhuang and Han populations Wu J, Yin R, Lin W, Pan S, Yang D Ref: Lipids, 43:733, 2008 : PubMed ESTHER: Wu_2008_Lipids_43_733 PubMedSearch: Wu 2008 Lipids 43 733 PubMedID: 18592285 Gene_locus related to this paper: human-LIPC Abstract Hei Yi Zhuang is an isolated subgroup of the Zhuang minority in China. This study was designed to compare the difference in the hepatic lipase gene (LIPC) -514C/T polymorphism and its association with lipid profiles between the Guangxi Hei Yi Zhuang and Han populations. Genotyping of the LIPC -514C/T was performed in 873 subjects of Hei Yi Zhuang and 867 participants of Han Chinese. The frequency of -514T allele was 43.47% in Hei Yi Zhuang, and 36.10% in Han (P < 0.001). The frequencies of CC, CT and TT genotypes were 30.01, 53.04 and 16.95% in Hei Yi Zhuang, and 40.95, 45.91 and 13.14% in Han (P < 0.001); respectively. Serum high-density lipoprotein cholesterol (HDL-C) and apolipoprotein B levels in both ethnic groups were higher in LIPC -514T carriers than in C carriers. In addition, serum triglyceride levels in Han were higher in TT genotype individuals than in CC genotype subjects (P < 0.05). Serum HDL-C levels were positively correlated with age, alcohol consumption and LIPC -514C/T genotypes, and negatively associated with hypertension and cigarette smoking in Hei Yi Zhuang (P < 0.05-0.01), whereas HDL-C levels were positively correlated with age, alcohol consumption and LIPC -514C/T genotypes, and negatively associated with body mass index and cigarette smoking in Han (P < 0.05-0.001). The differences in serum HDL-C levels between the two ethnic groups might partially attribute to the differences in the LIPC -514C/T polymorphism. Title: Lipoprotein lipase gene polymorphism at the PvuII locus and serum lipid levels in Guangxi Hei Yi Zhuang and Han populations Yin R, Wang Y, Chen G, Lin W, Yang D, Pan S Ref: Clinical Chemistry & Laboratory Medicine, 44:1416, 2006 : PubMed ESTHER: Yin_2006_Clin.Chem.Lab.Med_44_1416 PubMedSearch: Yin 2006 Clin.Chem.Lab.Med 44 1416 PubMedID: 17163816 Abstract BACKGROUND: Hei Yi (which means "black worship" and "black dressing") Zhuang is a specific subgroup of the Zhuang nationality in China. Little is known about the relationship between genetic factors and lipid profiles in this population. Therefore, the present study was undertaken to compare the effects of lipoprotein lipase gene polymorphism at the PvuII locus on lipid levels in the Guangxi Hei Yi Zhuang and Han populations. METHODS: A total of 325 Hei Yi Zhuang subjects aged from 20 to 80 years were surveyed using stratified randomized cluster sampling. Serum levels of lipids and apolipoproteins were measured. Gene polymorphism was determined using polymerase chain reaction and restriction fragment length polymorphism. The results were compared with those for 331 matched Han subjects living in the same district. RESULTS: Serum levels of total cholesterol, triglycerides, low-density lipoprotein cholesterol and apolipoprotein B were significantly lower in Hei Yi Zhuang than in Han subjects (p<0.05-0.01), whereas the levels of high-density lipoprotein cholesterol and the ratio of apolipoprotein A1 to apolipoprotein B were significantly higher in Hei Yi Zhuang than in Han subjects (both p<0.01). The allelic frequencies for P+ and P- were 52.92% and 47.08% in Hei Yi Zhuang, and 58.46% and 41.54% in Han subjects (p<0.05), respectively. The frequencies of P+P+, P+P- and P-P- genotypes were 23.08%, 59.69% and 17.23% in Hei Yi Zhuang, and 29.31%, 58.31% and 12.38% in Han subjects (p>0.05), respectively. There were no significant differences or no significant correlation between serum lipid parameters and genotypes in Hei Yi Zhuang or Han subjects, or for the combined population of Hei Yi Zhuang and Han (all p>0.05). CONCLUSIONS: The allelic frequencies of the lipoprotein lipase gene at the PvuII locus in Hei Yi Zhuang were different from those in Han subjects, but the genotypic frequencies in Hei Yi Zhuang subjects were not different from those in Han subjects. There was no significant correlation between polymorphism of the lipoprotein lipase gene at the PvuII site and serum lipid levels in the two ethnic groups.

The 14.8-billion bp DNA sequence was generated over 9 months from 27,271,853 high-quality sequence reads (5.11-fold coverage of the genome) from both ends of plasmid clones made from the DNA of five individuals. Two assembly strategies-a whole-genome assembly and a regional chromosome assembly-were used, each combining sequence data from Celera and the publicly funded genome effort. The public data were shredded into 550-bp segments to create a 2.9-fold coverage of those genome regions that had been sequenced, without including biases inherent in the cloning and assembly procedure used by the publicly funded group. This brought the effective coverage in the assemblies to eightfold, reducing the number and size of gaps in the final assembly over what would be obtained with 5.11-fold coverage. The two assembly strategies yielded very similar results that largely agree with independent mapping data. The assemblies effectively cover the euchromatic regions of the human chromosomes. More than 90% of the genome is in scaffold assemblies of 100,000 bp or more, and 25% of the genome is in scaffolds of 10 million bp or larger. Analysis of the genome sequence revealed 26,588 protein-encoding transcripts for which there was strong corroborating evidence and an additional approximately 12,000 computationally derived genes with mouse matches or other weak supporting evidence. Although gene-dense clusters are obvious, almost half the genes are dispersed in low G+C sequence separated by large tracts of apparently noncoding sequence. Only 1.1% of the genome is spanned by exons, whereas 24% is in introns, with 75% of the genome being intergenic DNA. Duplications of segmental blocks, ranging in size up to chromosomal lengths, are abundant throughout the genome and reveal a complex evolutionary history. Comparative genomic analysis indicates vertebrate expansions of genes associated with neuronal function, with tissue-specific developmental regulation, and with the hemostasis and immune systems. DNA sequence comparisons between the consensus sequence and publicly funded genome data provided locations of 2.1 million single-nucleotide polymorphisms (SNPs). A random pair of human haploid genomes differed at a rate of 1 bp per 1250 on average, but there was marked heterogeneity in the level of polymorphism across the genome. Less than 1% of all SNPs resulted in variation in proteins, but the task of determining which SNPs have functional consequences remains an open challenge.

We have determined the nucleotide sequence of nearly all of the approximately 120-megabase euchromatic portion of the Drosophila genome using a whole-genome shotgun sequencing strategy supported by extensive clone-based sequence and a high-quality bacterial artificial chromosome physical map. Efforts are under way to close the remaining gaps; however, the sequence is of sufficient accuracy and contiguity to be declared substantially complete and to support an initial analysis of genome structure and preliminary gene annotation and interpretation. The genome encodes approximately 13,600 genes, somewhat fewer than the smaller Caenorhabditis elegans genome, but with comparable functional diversity. | |||||||
