Hepatocyte-specific HuR knockout will reduce the expression of APOB, UQCRB, and NDUFB6 in mice, thereby reducing liver lipid transport and ATP synthesis, exacerbating high-fat diet (HFD)-induced NAFLD.432 A recent study revealed433 that death-associated protein kinase-related apoptosis-inducing kinase 2 (DRAK2) directly binds to SRSF6, inhibits the phosphorylation of SRSF6 by SRSF kinase SRPK1, leading to abnormal AS isoforms of mitochondrial function-related genes (Polg2, Nudt13, Guf1, Rnasel and Nme4), promoting the progression of hepatic steatosis to non-alcoholic hepatitis. The gene discussed is APOB; the disease is fatty liver disease.
