A proposed model of miRNA expression regulation in HHcy-induced liver injury. Under the condition of hyperhomocysteinemia (HHcy), down-regulated miR-212-5p specifically upregulates PSMD10 expression in hepatocytes. PSMD10 then activates ER stress through interacting with GRP78 and facilitates apoptosis of hepatocytes, by which Hcy induces liver injury
