Liver-derived Exosomal miRNA in NAFLD: Mechanisms of Action, Biomarkers, and Therapeutic Applications.

Nonalcoholic fatty liver disease (NAFLD) is of global concern due to its high prevalence worldwide. NAFLD, as one of the most common causes of liver function abnormalities, is associated with obesity, insulin resistance, and type 2 diabetes mellitus, and there are no medications available to treat NAFLD. Extracellular vesicles (EVs) are nanosized, membrane-bound vesicles that deliver biomolecules between cells.

Ferroptosis as an emerging therapeutic target in liver diseases.

Ferroptosis is an iron-dependently nonapoptotic cell death characterized by excessive accumulation of lipid peroxides and cellular iron metabolism disturbances. Impaired iron homeostasis and dysregulation of metabolic pathways are contributors to ferroptosis. As a major metabolic hub, the liver synthesizes and transports plasma proteins and endogenous fatty acids.

The essential effect of mTORC1-dependent lipophagy in non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is a chronic progressive liver disease with increasing prevalence. Lipophagy is a type of programmed cell death that plays an essential role in maintaining the body's balance of fatty acid metabolism. However, the livers of NAFLD patients are abnormally dysregulated in lipophagy.

Osthole delays hepatocarcinogenesis in mice by suppressing AKT/FASN axis and ERK phosphorylation.

Hepatocellular carcinoma (HCC) is one of the most common fatal malignancies worldwide. Inhibition of the lipogenic enzymes involved in hepatic de novo lipogenesis can both effectively restrain proliferation of HCC cells in vitro and reduce the risk of hepatocarcinogenesis in vivo. Although a natural coumarin derivative osthole shows efficacy in suppressing cell proliferation and inducing apoptosis in cultured hepatoma cells and HCC xenograft tumors, the molecular mechanism by which osthole delays hepatocellular malignant transformation during lipogenesis-driven hepatocarcinogenesis remains unknown.
