The identification of mechanisms to store glucose carbon in the form glycogen rather than fat hepatocytes has important implications for prevention nonalcoholic fatty liver disease (NAFLD) and other chronic metabolic diseases. In this work, we show that glycogenesis uses its intermediate metabolite uridine diphosphate (UDPG) antagonize lipogenesis, thus steering both mouse human toward storing as glycogen. underlying mechanism involves transport UDPG Golgi apparatus, where it binds site-1 protease (S1P) inhibits S1P-mediated cleavage sterol regulatory element-binding proteins (SREBPs), thereby inhibiting lipogenesis hepatocytes. Consistent with mechanism, administration is effective at treating NAFLD a model organoids. These findings indicate potential opportunity ameliorate disordered metabolism liver.

Abstract Nonalcoholic fatty liver disease, also called metabolic dysfunction‐associated steatotic is the most common disease worldwide and has no approved pharmacotherapy. Due to its beneficial effects on regulation, inflammation suppression, cell death prevention, fibrogenesis inhibition, farnesoid X receptor (FXR) widely accepted as a promising therapeutic target for nonalcoholic steatosis (NASH) or steatohepatitis (MASH). Many FXR agonists have been developed NASH/MASH therapy. Obeticholic acid (OCA) pioneering frontrunner agonist first demonstrating success in clinical trials. Unfortunately, OCA did not receive regulatory approval NASH pharmacotherapy because moderate benefits outweigh safety risks, which may cast shadow over FXR‐based drug development NASH/MASH. This review summarizes milestones of discuss limitations, including hepatoprotection undesirable side dyslipidemia, pruritus, cholelithiasis, toxicity risk, depth. More importantly, we provide perspectives therapy NASH/MASH, hoping support successful bench‐to‐clinic transition.

Abstract The gut microbiota plays a critical role in maintaining human health, influencing wide range of physiological processes, including immune regulation, metabolism, and neurological function. Recent studies have shown that imbalances composition can contribute to the onset progression various diseases, such as metabolic disorders (e.g., obesity diabetes) neurodegenerative conditions Alzheimer's Parkinson's). These are often accompanied by chronic inflammation dysregulated responses, which closely linked specific forms cell death, pyroptosis ferroptosis. Pathogenic bacteria trigger these death pathways through toxin release, while probiotics been found mitigate effects modulating responses. Despite insights, precise mechanisms influences diseases remain insufficiently understood. This review consolidates recent findings on impact immune‐mediated inflammation‐associated conditions. It also identifies gaps current research explores potential advanced technologies, organ‐on‐chip models microbiome–gut–organ axis, for deepening our understanding. Emerging tools, single‐bacterium omics spatial metabolomics, discussed their promise elucidating microbiota's disease development.
