The MASLD symptoms include dyslipidemia, hyperglycemia, insulin resistance and obesity, the liver manifestations of metabolic syndrome. Treatment option for MASH fibrosis is limited. Since the discovery of bile acids as the endogenous ligands of farnesoid X receptor (FXR) in early 1990, bile acid and FXR based-drug therapies have been developed and tested in clinical trials for cholestatic liver diseases and MASH fibrosis. However, many of these drugs have unwanted side-effects and moderate efficacy in improving fibrosis. The US Food and Drug Administration has not approved any of bile acid- and FXR-based drugs for MASH fibrosis. Drug therapies alternative to bile acid derivatives for MASH have been in clinical trials. Recently, resmetirom, a liver-specific- and thyroid hormone receptor beta-selective agonist has been approved for MASH fibrosis. Glucagon-like peptide-1 receptor agonists also are in clinical trials for MASH. This review covers recent development of novel drug therapies for MASH fibrosis, T2D and obesity.</div></div>","PeriodicalId":36741,"journal":{"name":"Liver Research","volume":"9 2","pages":"Pages 94-103"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the liver is susceptible to both acute and chronic disorders, with chronic conditions being fatal. Chronic liver diseases (CLDs), such as liver fibrosis, which usually represents the early manifestation of cirrhosis, primarily result from hepatitis B and C viruses infections, metabolic disorders, alcohol abuse, immune-mediated attacks, and cholestatic injury. The progression of liver fibrosis contributes to the development of cirrhosis, which can further lead to hepatocellular carcinoma, portal hypertension, hepatic decompensation, and hepatic encephalopathy. The extracellular matrix deposition over time leading the hepatocyte necrosis (cirrhosis) is the main structural feature of CLDs and may cause hepatic failure. Certain conditions, such as hepatitis and autoimmune diseases, may promote the rapid deterioration of liver function. Acute and chronic liver failure causes may vary, with early referral for liver transplantation improving the chance of recovery. The healthcare system need improvements to manage patients with non-alcoholic fatty liver disease and alcoholic fatty liver disease, as they have the potential to progress to cirrhosis. Both conditions involve the release of reactive oxygen species and damage-associated molecular patterns from cytokines, hepatic stellate cells, and hepatocyte autophagy, leading to prolonged inflammation. While various medications target fibrosis and liver damage, nanoparticle-based drug delivery systems offer additional promise by promoting faster liver regeneration.

The pH values and hepatic enzyme levels of cold preservation solutions and perfusate serve as dynamic indicators of hepatic injury.
