Our previous studies found that carnosic acid (CA), an important polyphenol antioxidant, could significantly delay Abeta(1-42)-mediated acute paralysis. However, many details and underlying mechanisms of CA's neuroprotection against Abeta-induced cholinergic system defects and mitochondrial dysfunction remain unclear. Herein, we deeply investigated the effects and the possible mechanisms of CA-mediated protection against Abeta toxicity in vivo through several AD Caenorhabditis elegans strains. The results showed CA delayed age-related paralysis and Abeta deposition, and significantly protected neurons from Abeta-induced toxicity. CA might downgrade the expression of ace-1 and ace-2 genes, and upregulate cha-1 and unc-17 genes to inhibit acetylcholinesterase activity and relieve Abeta-caused cholinergic system defects. Furthermore, CA might also ameliorate Abeta-induced mitochondrial imbalance and oxidative stress through up-regulating the expression of phb-1, phb-2, eat-3, and drp-1 genes. The enhancements of the cholinergic system and mitochondrial function might be the reasons for the amelioration of Abeta-mediated toxicity and Abeta aggregation mediated by CA. These findings have helped us to understand the CA anti-Abeta activity in C. elegans and the potential mechanism of action. Title: Pisa syndrome in dementia with Lewy bodies: A Chinese multicenter study Su Z, Liu S, Chen G, Gan J, Bao X, Zhu H, Wang X, Wu H, Ji Y Ref: Parkinsonism Relat Disord, 103:50, 2022 : PubMed ESTHER: Su_2022_Parkinsonism.Relat.Disord_103_50 PubMedSearch: Su 2022 Parkinsonism.Relat.Disord 103 50 PubMedID: 36041278 Abstract BACKGROUND: Pisa syndrome (PS) is rarely reported in Dementia with Lewy bodies (DLB). The aim of this article is to investigate the prevalence rate of PS and the correlation with clinical features evaluated in patients with DLB. METHODS: A total of 209 DLB patients were consecutively recruited and underwent standardized clinical evaluation in our multicenter study. The associations between PS and clinical factors were evaluated. RESULTS: The prevalence rate of PS in patients with DLB was 15.3%, which was higher in the moderate and severe stages than mild cognitive impairment and mild stages (81.2% vs. 18.8%). Patients with PS had a longer duration of disease (P = 0.020) and parkinsonism (P = 0.003), higher scores of NPI (P = 0.028), ADL (P = 0.002) and UPDRS part III (P < 0.001), lower scores of clock drawing test (P = 0.009), visuospatial/executive abilities (P = 0.018), attention (P = 0.020), language and praxis (P = 0.020), registration (P = 0.012), greater H&Y stage (P < 0.001), and higher proportion of cholinesterase inhibitors used (P = 0.044) than those without PS. Longer disease duration (OR = 1.166, P = 0.023), presence of parkinsonism (OR = 7.971, P = 0.007), moderate and severe dementia (OR = 3.215, P = 0.021) were associated with the presence of PS. Patients had a longer duration of PS (P = 0.014) and lower mean age of onset (P = 0.040) in the group with severe lateral trunk flexion. CONCLUSION: The development of PS may be associated with longer disease duration, the presence of parkinsonism and severe stages of dementia in DLB. Cholinesterase inhibitors may have a correlation with PS. The severity of lateral flexion is related to the duration of PS and mean age of onset. Title: Enzyme-Triggered Disassembly of Perylene Monoimide-based Nanoclusters for Activatable and Deep Photodynamic Therapy Cai Y, Ni D, Cheng W, Ji C, Liu Y, Su Z, Chen C, Yin M, Mullen K, Wang Y Ref: Angew Chem Int Ed Engl, :, 2020 : PubMed ESTHER: Cai_2020_Angew.Chem.Int.Ed.Engl__ PubMedSearch: Cai 2020 Angew.Chem.Int.Ed.Engl PubMedID: 32363672 Abstract Photodynamic therapy (PDT) exhibits great potential for cancer therapy, but still suffers from nonspecific photosensitivity and poor penetration of photosensitizer. Here, a smart perylene monoimide-based nanocluster with enzyme-triggered disassembly is reported as an activatable and deeply penetrable photosensitizer. A novel carboxylesterase (CE)-responsive tetrachloroperylene monoimide (P1) was synthesized and assembled with folate-decorated albumins into a nanocluster ( FHP ) with a diameter of ~100 nm. Once P1 is hydrolyzed by the tumor-specific CE, FHP disassembles into ultrasmall nanoparticles (~10 nm), facilitating the deep tumor penetration of FHP . Furthermore, such enzyme-triggered disassembly of FHP leads to enhanced fluorescence intensity (~8-fold) and elevated singlet oxygen generation ability (~4-fold), enabling in situ near-infrared fluorescence imaging and promoted PDT. FHP permits remarkable tumor inhibition in vivo with minimal side effects through imaging-guided, activatable, and deep PDT. This work confirms that this cascaded multifunctional control via enzyme-triggered molecular disassembly is an effective strategy for precise cancer theranostics. Title: Hippocampal Proteomic Alteration in Triple Transgenic Mouse Model of Alzheimer's Disease and Implication of PINK 1 Regulation in Donepezil Treatment Zhou X, Xiao W, Su Z, Cheng J, Zheng C, Zhang Z, Wang Y, Wang L, Xu B and Pui Man Hoi M <2 more author(s)> Zhou X, Xiao W, Su Z, Cheng J, Zheng C, Zhang Z, Wang Y, Wang L, Xu B, Li S, Yang X, Pui Man Hoi M (- 2) Ref: J Proteome Res, 18:1542, 2019 : PubMed ESTHER: Zhou_2019_J.Proteome.Res_18_1542 PubMedSearch: Zhou 2019 J.Proteome.Res 18 1542 PubMedID: 30484658 Abstract Donepezil is a clinically approved acetylcholinesterase inhibitor (AChEI) for cognitive improvement in Alzheimer's disease (AD). Donepezil has been used as a first-line agent for the symptomatic treatment of AD, but its ability to modify disease pathology and underlying mechanisms is not clear. We investigated the protective effects and underlying mechanisms of donepezil in AD-related triple transgenic (APPSwe/PSEN1M146V/MAPTP301L) mouse model (3xTg-AD). Mice (8-month old) were treated with donepezil (1.3 mg/kg) for 4 months and evaluated by behavioral tests for assessment of cognitive functions, and the hippocampal tissues were examined by protein analysis and quantitative proteomics. Behavioral tests showed that donepezil significantly improved the cognitive capabilities of 3xTg-AD mice. The levels of soluble and insoluble amyloid beta proteins (Abeta1-40 and Abeta1-42) and senile plaques were reduced in the hippocampus. Golgi staining of the hippocampus showed that donepezil prevented dendritic spine loss in hippocampal neurons of 3xTg-AD mice. Proteomic studies of the hippocampal tissues identified 3131 proteins with altered expression related to AD pathology, of which 262 could be significantly reversed with donepezil treatment. Bioinformatics with functional analysis and protein-protein interaction (PPI) network mapping showed that donepezil significantly elevated the protein levels of PINK 1, NFASC, MYLK2, and NRAS in the hippocampus, and modulated the biological pathways of axon guidance, mitophagy, mTOR, and MAPK signaling. The substantial upregulation of PINK 1 with donepezil was further verified by Western blotting. Donepezil exhibited neuroprotective effects via multiple mechanisms. In particular, PINK 1 is related to mitophagy and cellular protection from mitochondrial dysfunction, which might play important roles in AD pathogenesis and represent a potential therapeutic target. Title: Granularity and Laxative Effect of Ultrafine Powder of Dendrobium officinale Luo D, Qu C, Zhang Z, Xie J, Xu L, Yang H, Li C, Lin G, Wang H, Su Z Ref: J Med Food, 20:180, 2017 : PubMed ESTHER: Luo_2017_J.Med.Food_20_180 PubMedSearch: Luo 2017 J.Med.Food 20 180 PubMedID: 28146409 Abstract Constipation is a common disorder that is a significant source of morbidity among people around the world ranging from 2% to 28%. Dendrobium officinale Kimura et Migo is a traditional herbal medicine and health food used for tonicity of the stomach and promotion of body fluid production in China. This study aimed to prepare the ultrafine powder of Dendrobium officinale (UDO) and investigate its laxative effect and potential mechanism in mice with diphenoxylate-induced constipation. Results indicated that the mean diameter (d50) of UDO obtained by ball milling was 6.56 mum. UDO (62.5, 125, and 250 mg/kg, p.o.) could significantly enhance the gastrointestinal transit ratio and promote fecal output. Moreover, UDO treatment resulted in significant increases in the serum levels of acetylcholinesterase (AChE), gastrin (Gas), motilin (MTL), and substance P (SP), and obviously decreased serum contents of somatostatin (SS). Taken together, UDO, which can be easily obtained through milling to a satisfactory particle size, exhibited obvious laxative effect in diphenoxylate-induced constipated mice, and the mechanism might be associated with elevated levels of AChE, Gas, MTL, SP, and reduced production of SS. UDO has the potential for further development into an alternative effective diet therapy for constipation. Title: Intranasal administration of TAT-haFGF(14-154) attenuates disease progression in a mouse model of Alzheimer's disease Lou G, Zhang Q, Xiao F, Xiang Q, Su Z, Zhang L, Yang P, Yang Y, Zheng Q, Huang Y Ref: Neuroscience, 223:225, 2012 : PubMed ESTHER: Lou_2012_Neurosci_223_225 PubMedSearch: Lou 2012 Neurosci 223 225 PubMedID: 22885230 Abstract Human acidic fibroblast growth factor (haFGF), a neurotrophin-like growth factor in the brain, plays important roles in the development, differentiation and regeneration of brain neurons, which makes it potential to treat Alzheimer's disease (AD). In this study, haFGF(14-154) and TAT-haFGF(14-154) (haFGF(14-154) fused with the cell-penetrating peptide transactivator of transcription protein transduction domain (TAT-PTD)) were intranasally administrated for 5 weeks to investigate the effects on senescence-accelerated mouse prone-8 (SAMP8) mice (a mouse model of AD). Results showed that TAT-PTD could increase the concentration of haFGF in the brain significantly, and TAT-haFGF(14-154) was more effective than haFGF(14-154) in the same dosage (300 ug/kg). Importantly, TAT-haFGF(14-154) improved the learning and memory abilities of SAMP8 mice in the behavioral test, and promoted the function of cholinergic system by measuring the relevant biomarkers (acetylcholine (ACh) level, acetylcholinesterase (AChE) and choline acetyltransferase (ChAT) activities). TAT-haFGF(14-154) also significantly reduced beta-amyloid protein(1-42) (Abeta(1-42)) deposits as well as the levels of Abeta soluble forms in the mice brains and prevented the neurons from apoptosis. Besides, the oxidative stress impairment in the brain and serum was also ameliorated. The results suggest that TAT-haFGF(14-154) could attenuate the disease progression of SAMP8 AD mice, and the mechanism is related to the regulation of neurons microenvironment including neurotransmitters, Abeta pathology and oxidative stress. Title: DWARF27, an iron-containing protein required for the biosynthesis of strigolactones, regulates rice tiller bud outgrowth Lin H, Wang R, Qian Q, Yan M, Meng X, Fu Z, Yan C, Jiang B, Su Z and Wang Y <1 more author(s)> Lin H, Wang R, Qian Q, Yan M, Meng X, Fu Z, Yan C, Jiang B, Su Z, Li J, Wang Y (- 1) Ref: Plant Cell, 21:1512, 2009 : PubMed ESTHER: Lin_2009_Plant.Cell_21_1512 PubMedSearch: Lin 2009 Plant.Cell 21 1512 PubMedID: 19470589 Abstract Tillering in rice (Oryza sativa) is one of the most important agronomic traits that determine grain yields. Previous studies on rice tillering mutants have shown that the outgrowth of tiller buds in rice is regulated by a carotenoid-derived MAX/RMS/D (more axillary branching) pathway, which may be conserved in higher plants. Strigolactones, a group of terpenoid lactones, have been recently identified as products of the MAX/RMS/D pathway that inhibits axillary bud outgrowth. We report here the molecular genetic characterization of d27, a classic rice mutant exhibiting increased tillers and reduced plant height. D27 encodes a novel iron-containing protein that localizes in chloroplasts and is expressed mainly in vascular cells of shoots and roots. The phenotype of d27 is correlated with enhanced polar auxin transport. The phenotypes of the d27 d10 double mutant are similar to those of d10, a mutant defective in the ortholog of MAX4/RMS1 in rice. In addition, 2'-epi-5-deoxystrigol, an identified strigolactone in root exudates of rice seedlings, was undetectable in d27, and the phenotypes of d27 could be rescued by supplementation with GR24, a synthetic strigolactone analog. Our results demonstrate that D27 is involved in the MAX/RMS/D pathway, in which D27 acts as a new member participating in the biosynthesis of strigolactones.

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: ABT-089: pharmacological properties of a neuronal nicotinic acetylcholine receptor agonist for the potential treatment of cognitive disorders Rueter LE, Anderson DJ, Briggs CA, Donnelly-Roberts D, Gintant GA, Gopalakrishnan M, Lin NH, Osinski MA, Reinhart GA and Sullivan JP <8 more author(s)> Rueter LE, Anderson DJ, Briggs CA, Donnelly-Roberts D, Gintant GA, Gopalakrishnan M, Lin NH, Osinski MA, Reinhart GA, Buckley MJ, Martin RL, McDermott JS, Preusser LC, Seifert TR, Su Z, Cox BF, Decker MW, Sullivan JP (- 8) Ref: CNS Drug Rev, 10:167, 2004 : PubMed ESTHER: Rueter_2004_CNS.Drug.Rev_10_167 PubMedSearch: Rueter 2004 CNS.Drug.Rev 10 167 PubMedID: 15179445 Abstract ABT-089 [2-methyl-3-(2-(S)-pyrrolidinylmethoxy)pyridine dihydrochloride salt] is a selective neuronal nicotinic receptor (NNR) modulator with cognitive enhancing properties in animal models of cognitive functioning. Amongst NNR subtypes, ABT-089 shows selectivity for the cytisine binding site on the alpha4beta2 receptor subtype as compared to the alpha-bungarotoxin (alpha-BgT) binding sites on the alpha7 and alpha1beta1deltagamma receptor subtypes. In functional in vitro electrophysiological and cation flux assays, ABT-089 displays differential activity including agonism, partial agonism and antagonism depending upon the NNR subtype and assay. ABT-089 is as potent and efficacious as (-)-nicotine at evoking acetylcholine (ACh) release from hippocampal synaptosomes. Furthermore, ABT-089 is neuroprotective against excitotoxic glutamate insults, with even greater potency seen after chronic treatment. Similarly, ABT-089 is effective in models of cognitive functioning, including enhancement of baseline functioning as well as improvement of impaired cognitive functioning seen following septal lesioning and natural aging. In neuroprotective assays the compound is most potent by chronic administration. In stark contrast to the positive effects in the cognitive models, ABT-089 shows little propensity to induce adverse effects such as ataxia, hypothermia, seizures, cardiovascular or gastrointestinal side effects. Together these data suggest that ABT-089 is a NNR modulator with the potential for treating cognitive disorders with markedly limited adverse cardiovascular and gastrointestinal side effects. | |||||||
