It is reported that AR could regulate arachidonic acid metabolism and ether lipid metabolism by modulating the expressions of cytochrome P450 1A2 (CYP1A2), phosphate Cytidylyltransferase 1A (PCYT1A) and cytochrome P450 Family one Subfamily B Member 1 (CYP1B1) through network pharmacology techniques, to effectively ameliorate liver fibrosis (Wang et al., 2019). The gene discussed is CYP1A2; the disease is Hepatic fibrosis.
