Mitochondrial dynamics, quality control and mtDNA in Alcohol-associated liver disease and liver cancer

Hepatology. 2024 Apr 29. doi: 10.1097/HEP.0000000000000910. Online ahead of print.ABSTRACTMitochondria are intracellular organelles responsible for energy production, glucose and lipid metabolism, cell death, cell proliferation, and innate immune response. Mitochondria are highly dynamic organelles that constantly undergo fission, fusion, and intracellular trafficking, as well as degradation and biogenesis. Mitochondrial dysfunction has been implicated in a variety of chronic liver diseases including alcohol-associated liver disease (ALD), metabolic dysfunction-associated steatohepatitis (MASH), and hepatocellular carcinoma (HCC). In this review, we provide a detailed overview of mitochondrial dynamics, mitophagy, and mtDNA-mediated innate immune response, and how dysregulation of these mitochondrial processes affects the pathogenesis of ALD and HCC. Mitochondrial dynamics and mtDNA-mediated innate immune response may thereby represent an attractive therapeutic target for ameliorating ALD and alcohol-associated HCC.PMID:38683546 | DOI:10.1097/HEP.0000000000000910
