Third, as inflammation is a critical factor in the progression of fatty liver disease from simple steatosis to NASH, we also analyzed two inflammatory marker genes - adhesion G protein-coupled receptor E1 (Adgre1, also named Emr1 or F4/80) and chemokine (C-C motif) ligand 2 (Ccl2, also named MCP-1). The gene discussed is CCL2; the disease is steatosis.
