Gut microbiota plays an essential role in the progression of nonalcoholic fatty liver disease (NAFLD), making gut-liver axis a potential therapeutic strategy. Bacteroides genus, enriched gut symbionts, has shown promise treating liver. However, further investigation is needed to identify specific beneficial strains for metabolic disorders NAFLD and elucidate their underlying mechanisms. In this study, we observed positive correlation between abundance thetaiotaomicron (B. theta) alleviation...

The pandemic of SARS-CoV-2 worldwide with successive emerging variants urgently calls for small-molecule oral drugs broad-spectrum antiviral activity. Here, we show that carrimycin, a new macrolide antibiotic in the clinic and an candidate phase III trials, decreases efficiency programmed –1 ribosomal frameshifting coronaviruses thus impedes viral replication fashion. Carrimycin binds directly to coronaviral frameshift-stimulatory element (FSE) RNA pseudoknot, interrupting protein...

Berberine (BBR), a small alkaloid, is used as hypoglycemic agent in China. Stachyose (Sta), Rehmannia glutinosa oligosaccharide, acts prebiotic. This study aimed to evaluate whether BBR combined with Sta produced better glycometabolism than alone, and explored the effects on gut microbiota metabolomics. Type-2 diabetic db/db mice were administered (100 mg/kg), (200 or both by gavage once daily. Glucose metabolism, balance of α- β-cells, mucin-2 expression ameliorated treatment Sta, stronger...

Berberine (BBR) has the beneficial effects of anti-inflammation, anti-bacteria, and anti-diabetes. The clinical application BBR been hindered by its poor gastrointestinal absorption. Stachyose (Sta), a prebiotic agent, improves composition gut microbiota benefits for diabetes. We therefore investigated whether Sta anti-diabetic actions using KKAy mice. Here, we find that combination is more effective than alone in blood glucose control, improvement insulin resistance islet functions,...

Helicobacter pylori (H. pylori) has characteristics of family cluster infection; however, its family-based infection status, related factors, and transmission pattern in central China, a high-risk area for H. gastric cancer, have not been evaluated. We investigated healthy households to understand patterns disease prevention.To investigate prevention.Blood samples survey questionnaires were collected from 282 families including 772 individuals. The recruited 10 selected communities the...

3-Hydroxy-3-methyl-glutaryl CoA (HMG-CoA) reductase inhibitors or statins are competitive of the rate-limiting enzyme in cholesterol biosynthesis. Currently, used as first-line therapy treatment diabetic dyslipidemia. However, effects on β cell function remains unclear. This study aims to examine atorvastatin pancreatic obese C57BL/6 J mice and possible mechanisms. Diet-induced obesity (DIO) were treated with (30 mg/kg/day) for 58 days. was assessed by hyperglycemic clamp area...

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic worldwide, and there no specific drug to treat it. Recent results showed that 17-beta-hydroxysteroid dehydrogenase type 13 (HSD17B13) associated with diseases, but these conclusions are controversial. Here, we HSD17B13 was more highly expressed in livers of NAFLD patients, high expression induced murine models cultural hepatocytes treated using various etiologies. The facilitated progression by directly stabilizing...

Nonalcoholic fatty liver disease (NAFLD), ranging from simple steatosis to nonalcoholic steatohepatitis (NASH), is a worldwide without approved therapeutic drugs. Anti-inflammatory and hepatoprotective drug bicyclol multi-pharmacological active berberine, respectively, have shown beneficial effects on NAFLD in murine nutritional models patients, though the mechanisms remain be illustrated. Here, we investigated combined of berberine mouse induced by Western diet (WD), NASH WD/CCl4. The use...

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common metabolic of liver, characterized by hepatic steatosis in more than 5% hepatocytes. However, despite recent approval first drug, resmetirom, for management steatohepatitis, decades target exploration and hundreds clinical trials have failed, highlighting urgent need to find new druggable targets discovery innovative drug candidates against MASLD. Here, we found that glutathione S-transferase alpha 1 (GSTA1)...

Abstract Based on the multi‐target strategy to treat type 2 diabetes mellitus (T2DM), glucokinase/peroxisome proliferator‐activated receptor γ (GK/PPARγ) dual‐target molecules were constructed by rational combination of pharmacophores from known GK activators and PPARγ agonists. A series agents designed synthesized, their capacities induce transcriptional activity evaluated. Three these compounds showed particularly high potency toward GK, moderate PPARγ, structure–activity relationships...
