Background PIK3IP1 contains 1 kringle domain and is a negative regulator of phosphatidylinositol-3-kinase (PI3K), suppresses the development of hepatocellular carcinoma. PI3K is a well-known regulator of cell division, motility, metabolism and survival in most cell types. Proper liver function and development highly depend on intact PI3K signal transduction. Aberrant PI3K pathway signaling in the liver is associated with hepatocellular carcinoma. PI3K signaling is involved in the homeostasis of lipid and glucose metabolism. Activation of the PI3K pathway induces lipogenesis and glycogenesis in the liver, since both Akt overexpressing transgenic mice and PTEN knockout mice develop fatty liver and hypoglycemia. PIK3IP1 overexpression can contribute to glucose homeostasis and fatty deposition.
