Similarly, NOX4 expression was induced in HSCs isolated from mice after BDL, in hepatocytes isolated from CCl4‐treated mice and in mice subjected to fast‐food diet (FFD) and choline‐deficient amino acid‐defined (CDAA) dietary models of NASH.14, 16, 43. The gene discussed is NOX4; the disease is metabolic dysfunction-associated steatohepatitis.
