Abstract:
Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease, affecting more than 30% of adults and 7%-14% of youths globally. MASLD and its advanced form of metabolic dysfunction-associated steatohepatitis (MASH) can progress to liver cirrhosis and hepatocellular carcinoma. Despite its growing burden, effective therapies for MASLD and MASH remain limited. Accumulating evidence indicates that short-chain fatty acids (SCFAs) modulate the activation of hepatic innate and adaptive immune cells, influencing liver inflammation and fibrosis. Moreover, SCFAs modulate liver lipid and glucose metabolism and insulin sensitivity, affecting MASLD progression. This review summarizes the cellular and molecular mechanisms through which SCFAs impact liver inflammation, fibrosis, and energy metabolism. Several key molecular signaling pathways are discussed. Clinical trials aiming to modulate SCFA production through different treatments are reviewed. Collectively, emerging evidence supports that targeting SCFA-mediated function represents a promising therapeutic strategy for MASLD and MASH.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
