Insulin plays a central role in coordinating MetF through molecular mechanisms such as signaling pathways, transcriptional responses, and circadian regulation. Insulin resistance (IR) can impair MetF, contributing to type 2 diabetes and obesity, often stemming from continuous challenges such as sedentary lifestyles, poor diets, and circadian disruptions. Transient IR episodes, like gestational diabetes or stress-induced hyperglycemia, also heighten the risk of later diabetes development. Yet, the molecular processes post-transient IR remain poorly understood despite their health significance.<h3>Aims and Methods</h3>Our aims were to characterize the hepatic response to a high fat diet challenge in mice previously exposed to a transient IR episode. We integrated transcriptomic, epigenomic, lipidomic, and molecular clock assessments to provide a molecular basis for the observed dysregulations.<h3>Results</h3>Our study shows that temporarily blocking the insulin receptor in young mice leads to later-life liver issues hindering PPARα-mediated adaptation to a high-fat diet. This is linked to decreased histone active marks at PPARα sites and reduced endogenous PPARα ligands. Transient insulin receptor blockade also altered the liver's molecular clock, particularly affecting PPARα transcriptional responsiveness.<h3>Conclusions</h3>Seemingly reversible and unnoticed metabolic challenges in early adulthood may predispose the liver to exacerbated metabolic dysfunctions when confronted with chronic challenges later in life.","PeriodicalId":15888,"journal":{"name":"Journal of Hepatology","volume":"25 1","pages":""},"PeriodicalIF":25.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143393418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although fibroblast growth factor 21 (FGF21) analogs have shown promising therapeutic benefits for MASH in multiple preclinical and clinical studies, the underlying mechanisms remain elusive.<h3>Methods</h3>Liver-specific PPP6C knockout (PPP6C LKO) mice, βKlotho knockout (βKlotho LKO) and their wild-type littermates were fed with Amylin liver NASH (AMLN) diet for 16 weeks or choline-deficient, L-amino acid-defined, high-fat diet (CDA-HFD) for 8 weeks, followed by daily subcutaneous injection of rFGF21 (0.5 mg/kg) or vehicle for 4 weeks. Mass spectrometry assay was used for identification of PPP6C as a βKlotho binding protein. The <em>in vitro</em> phosphatase assay was used to evaluate the effects of FGF21 on PPP6C activity. Human studies shown that deregulation of PPP6C is associated with the progression of MASH.<h3>Results</h3>We identified serine and threonine phosphatase PPP6C as a direct target of FGF21. Hepatic PPP6C deficiency accelerates MASH progression in mice fed with AMLN diet or CDA-HFD, which blocks FGF21 action on MASH. Mechanistically, PPP6C is sufficient to interact with the coreceptor βKlotho upon FGF21 treatment, directly dephosphorylates tuberous sclerosis complex 2 (TSC2) at Ser939 and Thr1462, thereby inhibiting mTORC1 and promoting nuclear entry of TFE3 and Lipin1. In livers of MASH subjects, expression levels of PPP6C are decreased whereas TSC2 phosphorylation is elevated.<h3>Conclusions</h3>These results define a fundamental mechanism underlying FGF21 signals in hepatocytes and demonstrate that targeting PPP6C may have therapeutic potential for treating MASH.<h3>Impact and implications</h3>MASH is a severe chronic liver disease that increases susceptibility to more severe cirrhosis and hepatocellular carcinoma, yet currently lacks effective clinical therapeutic strategies. Here we have identified serine and threonine protein phosphatase PPP6C as a key regulator of MASH progression in mice and humans. PPP6C is directly activated by FGF21 via FGFRs/βKlotho and improves MASH features through dephosphorylation of TSC2 in hepatocytes. This study implies that pharmacological approaches, genetic or metabolic factors targeting PPP6C activity may offer attractive prospects for treating liver fibrosis and MASH.","PeriodicalId":15888,"journal":{"name":"Journal of Hepatology","volume":"15 1","pages":""},"PeriodicalIF":25.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143385128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study tested the efficacy and safety of icosabutate, a FFAR1/FFAR4 agonist, in MASH patients.<h3>Methods</h3>We performed a phase 2b, multicenter, 52-week, randomised, placebo-controlled trial (ICONA) testing the efficacy of icosabutate in MASH patients with F1-F3 (mild to severe) fibrosis. Patients were randomized 1:1:1 to receive once-daily, oral icosabutate 300 mg, 600 mg or placebo for 52 weeks. The primary efficacy endpoint was the proportion of patients with MASH resolution with no worsening of fibrosis in the 600 mg arm.<h3>Results</h3>The primary population for efficacy analysis comprised 187 patients [placebo (n=62), 300 mg icosabutate (n= 58) or 600 mg icosabutate (n=67)]. The percentage of patients with MASH resolution favoured the icosabutate 600 mg arm without reaching statistical significance (23.9% vs. 14.5%; odds ratio, 2.01; 95% confidence interval [CI], 0.8 to 5.08; P=0.13). A higher percentage of patients treated with icosabutate achieved a ≥1-stage improvement in fibrosis, with a response rate of 29.3% in the 300 mg arm (odds ratio, 2.89; 95% CI, 1.09 to 7.70))and 23.9% in the 600 mg arm (odds ratio, 2.4; 95% CI, 0.90 to 6.37)) vs. 11.3% in the placebo arm.
