Furthermore, in human, morbidly obese patients with hepatic steatosis showed an increase in hepatic TP53INP1 expression, and TP53INP1 expression was correlated with the level of a marker of hepatocyte death (keratin 18), with the grade of steatosis and with the expression level of the stress marker NQO1 (Supplementary Fig S2D–H and Supplementary Table S2). The gene discussed is KRT18; the disease is steatosis.
