Some researchers claim that it may suppress growth, migration, and invasion of gastric cancer cells in vitro and tumor growth and metastasis in vivo by upregulating the hepatocyte nuclear factor 4 alpha (HNF4α) [17], promoting apoptosis in human hepatoma cells in vitro [18], and acting as anti-inflammatory factor in rats [19]. The gene discussed is HNF4A; the disease is gastric cancer.
