Transforming growth factor-β-activated kinase 1 (TAK1) is a crucial central signaling molecule of hepatic cell death, inflammation and fibrogenesis through NF-κB and MAPK in metabolic dysfunction-associated steatotic liver disease (MASLD). Its pharmacological inhibition using the TAK1 inhibitor HS-276 was tested in vivo in a murine model of diet-induced MASLD.

There is a growing consensus that alcohol-related liver disease (ALD) should be considered a metabolic disorder under the influence of the gut-liver axis. Metabolome data have highlighted fatty acid-activated G protein-coupled receptors (GPCRs) as the main affected pathways, where the relationship of G-protein-coupled receptor 119 (GPR119) with ALD remains unexplored.

Adipose triglyceride lipase (ATGL), a central mediator of triglyceride hydrolysis and fatty acid mobilization, modulates hepatic lipid homeostasis and metabolic signaling pathways that contribute to the activation of fibrogenic responses.

Alterations in PNPLA3, particularly the I148M variant, impair lipid metabolism in hepatocytes, leading to lipid accumulation and driving progression from steatosis to fibrosis and cirrhosis. Targeting this genetic driver may offer a strategy to reduce steatosis and limit disease progression.

Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by lipid accumulation in the liver and inflammation. Sterol O-acyltransferase 2 (SOAT2) is a key enzyme in intestinal absorption and hepatic secretion of cholesterol. PRD Therapeutics Inc. has developed PRD-001, a selective SOAT2 inhibitor currently in phase I trials for MASH.

Several presentations at EASL highlight a new generation of therapies coming into view, with the work from Tune Therapeutics Inc. standing out as one of the most relevant for the novelty it represents and the step forward it signals. The company is investigating the use of TUNE-401 as a potential treatment for hepatitis B.

In the treatment of hepatocellular carcinoma (HCC), the long-term benefits of second-line tyrosine kinase inhibitors such as sorafenib are often limited by resistance mechanisms and adverse effects. The deubiquitinase ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) is upregulated in advanced HCC disease and has been linked to poor prognosis and treatment resistance.

Researchers from Pilatus Biosciences SA recently presented preclinical efficacy data for PLT-012, a humanized IgG4 antibody targeting CD36, in metabolic dysfunction-associated steatohepatitis (MASH) models.

At the recently concluded European Association for the Study of the Liver meeting, presentations underscored how increasingly granular insights into liver pathobiology are driving the rapid identification of new druggable targets across diverse indications.
