We next examined the H19 expression status during hepatic steatosis and found that during oleic acid (OA, at 0.05 mmol/L)‐induced hepatic steatosis,45 H19 expression was significantly up‐regulated in hepatocytes at 72 hours after OA treatment (Figure 1B, panels a and b), suggesting that H19 expression may be associated with hepatic steatosis. Here, H19 is linked to fatty liver disease.
