FABP1 and metabolic dysfunction-associated steatohepatitis: In addition, cytosolic proteins Acsl5 (long-chain fatty acid-CoA (Coenzyme A) ligase 5, KEGG: Fatty acid biosynthesis, degradation, and metabolism, PPAR signaling pathway, peroxisome) and Fabp1 (liver-specific fatty acid-binding protein 1, KEGG: PPAR signaling pathway, fat digestion and absorption) were increased in +NASH-MSC livers, indicating the stimulation of fatty acid activation towards triglyceride synthesis.
