Abstract
Alzheimer’s disease (AD) is the most common type of dementia and also one of the leading causes of death worldwide. However, the underlying mechanisms remain unclear, and currently there is no drug treatment that can prevent or cure AD. Here, we have applied the advantages of using induced pluripotent stem cell (iPSC)-derived neurons (iNs) from AD patients, which are able to offer human-specific drug responsiveness, in order to evaluate therapeutic candidates for AD. Using approach involving an inducible neurogenin-2 transgene, we have established a robust and reproducible protocol for differentiating human iPSCs into glutamatergic neurons. The AD-iN cultures that result have mature phenotypic and physiological properties, together with AD-like biochemical features that include extracellular β-amyloid (Aβ) accumulation and Tau protein phosphorylation. By screening using a gene set enrichment analysis (GSEA) approach, Graptopetalum paraguayense (GP) has been identified as a potential therapeutic agent for AD from among a range of Chinese herbal medicines. We found that administration of a GP extract caused a significantly reduction in the AD-associated phenotypes of the iNs, including decreased levels of extracellular Aβ40 and Aβ42, as well as reduced Tau protein phosphorylation at positions Ser214 and Ser396. Additionally, the effect of GP was more prominent in AD-iNs compared to non-diseased controls. These findings provide valuable information that suggests moving extracts of GP toward drug development, either for treating AD or as a health supplement to prevent AD. Furthermore, our human iN-based platform promises to be a useful strategy when it is used for AD drug discovery.

Construction of multiple linear regression models using blood biomarkers for selecting against abdominal fat traits in broilers. Poult Sci 2018; 97:17-23. [PMID: 29121351 DOI: 10.3382/ps/pex319] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Accepted: 09/24/2017] [Indexed: 01/16/2023] Open
Abstract
Plasma very low-density lipoprotein (VLDL) can be used to select for low body fat or abdominal fat (AF) in broilers, but its correlation with AF is limited. We investigated whether any other biochemical indicator can be used in combination with VLDL for a better selective effect. Nineteen plasma biochemical indicators were measured in male chickens from the Northeast Agricultural University broiler lines divergently selected for AF content (NEAUHLF) in the fed state at 46 and 48 d of age. The average concentration of every parameter for the 2 d was used for statistical analysis. Levels of these 19 plasma biochemical parameters were compared between the lean and fat lines. The phenotypic correlations between these plasma biochemical indicators and AF traits were analyzed. Then, multiple linear regression models were constructed to select the best model used for selecting against AF content. and the heritabilities of plasma indicators contained in the best models were estimated. The results showed that 11 plasma biochemical indicators (triglycerides, total bile acid, total protein, globulin, albumin/globulin, aspartate transaminase, alanine transaminase, gamma-glutamyl transpeptidase, uric acid, creatinine, and VLDL) differed significantly between the lean and fat lines (P < 0.01), and correlated significantly with AF traits (P < 0.05). The best multiple linear regression models based on albumin/globulin, VLDL, triglycerides, globulin, total bile acid, and uric acid, had higher R2 (0.73) than the model based only on VLDL (0.21). The plasma parameters included in the best models had moderate heritability estimates (0.21 ≤ h2 ≤ 0.43). These results indicate that these multiple linear regression models can be used to select for lean broiler chickens.

Human catalase gene promoter haplotype and cardiometabolic improvement after bariatric surgery. Gene 2018; 656:17-21. [PMID: 29496557 DOI: 10.1016/j.gene.2018.02.064] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2017] [Revised: 02/06/2018] [Accepted: 02/24/2018] [Indexed: 10/17/2022]
Abstract
Although its powerful impact on most co-morbidities has been widely demonstrated, the metabolic outcomes of bariatric surgery (BS) show a great heterogeneity among patients. Haplotypes of one of the major antioxidant enzyme, catalase (CAT), are associated with hypertension, dyslipidemia, and diabetes. The haplotype referred to as CAT1 includes homozygous carriers of CATH1 [-844G,-89A,-20T], whereas CAT2 haplotype includes heterozygous carriers (CATH1/CATH2) and CATH2 homozygous [-844A,-89T,-20C]. The aim of our study was to evaluate the impact of CAT1 and CAT2 haplotypes on traditional cardiovascular and metabolic markers one year after BS in a women population. The 294 women with a body mass index (BMI) >35 kg/m2 were followed-up for one year after BS, monitoring their anthropometric, metabolic and inflammatory parameters. CAT1 patients had significantly improved diastolic blood pressure (DBP) and Creactive protein (CRP) levels compared to CAT2 one year after BS. In untreated women at baseline, the change of CRP one year after BS was higher in CAT1 patients. In the population of women receiving at least one anti-lipidic, anti-hypertensive or anti-diabetic treatment at baseline, DBP and fat mass were lower one year after BS in CAT1 patients and the greater change of fat mass was associated with a higher change of adiponectin. The results highlight the beneficial impact of the CAT1 haplotype on traditional cardiovascular and metabolic parameters after BS. Our findings suggest that the CAT1 haplotype could be implicated in the level of metabolic and cardiovascular improvement after BS.

Gluconeogenesis, lipogenesis, and HBV replication are commonly regulated by PGC-1α-dependent pathway. Oncotarget 2016; 6:7788-803. [PMID: 25762623 PMCID: PMC4480716 DOI: 10.18632/oncotarget.3050] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2014] [Accepted: 01/06/2015] [Indexed: 12/22/2022] Open
Abstract
PGC-1α, a major metabolic regulator of gluconeogenesis and lipogenesis, is strongly induced to coactivate Hepatitis B virus (HBV) gene expression in the liver of fasting mice. We found that 8-Br-cAMP and glucocorticoids synergistically induce PGC-1α and its downstream targets, including PEPCK and G6Pase. Also, HBV core promoter activity was synergistically enhanced by 8-Br-cAMP and glucocorticoids. Graptopetalum paraguayense (GP), a herbal medicine, is commonly used in Taiwan to treat liver disorders. Partially purified fraction of GP (named HH-F3) suppressed 8-Br-cAMP/glucocorticoid-induced G6Pase, PEPCK and PGC-1α expression and suppressed HBV core promoter activity. HH-F3 blocked HBV core promoter activity via inhibition of PGC-1α expression. Ectopically expressed PGC-1α rescued HH-F3-inhibited HBV surface antigen expression, HBV mRNA production, core protein levels, and HBV replication. HH-F3 also inhibited fatty acid synthase (FASN) expression and decreased lipid accumulation by down-regulating PGC-1α. Thus, HH-F3 can inhibit HBV replication, gluconeogenesis and lipogenesis by down-regulating PGC-1α. Our study indicates that targeting PGC-1α may be a therapeutic strategy for treatment of HBV infections. HH-F3 may have potential use for the treatment of chronic hepatitis B patients with associated metabolic syndrome.

Abstract
BACKGROUND Many studies have demonstrated that Graptopetalum paraguayense has good antioxidant ability; however, few studies have examined its anti-inflammatory effect. The study aimed to investigate the anti-inflammatory effects of water extracts of G. paraguayense (WGP, 4 g day(-1)) in subjects with metabolic syndrome (MS). Intervention was administered for 12 weeks. Levels of inflammatory markers [high sensitivity C-reactive protein (CRP), tumour necrosis factor-α (TNF-α), and interleukin-6 (IL-6)] and antioxidant enzymes activities were measured. RESULTS Forty-two subjects completed the 12 week intervention study (placebo, n = 19; WGP, n = 23). After 12 weeks supplementation, subjects in WGP group had significantly lower levels of inflammatory markers than the baseline (P < 0.05) and the placebo group (CRP, P = 0.07; TNF-α, P = 0.04; IL-6, P = 0.03). The changes in levels of the inflammatory markers were significantly decreased in WGP group (CRP, P = 0.04; TNF-α, P = 0.06; IL-6, P = 0.01) compared to the placebo group. Levels of inflammatory markers were significantly negatively correlated with the antioxidant enzymes activities after supplementation. CONCLUSION This study demonstrated a significant reduction in inflammatory status in MS after WGP supplementation. WGP may exert an anti-inflammatory effect on MS in addition to its antioxidant ability.
