Effect of age on the etiologic role of the hepatitis B virus in hepatocellular carcinoma in blacks.

abstract：BACKGROUND & AIMS:The effects of aging on pancreatic acinar cell proliferation have not been clearly defined. Phosphatidylinositol 3-kinase (PI3K)-mediated phosphorylation of Akt is a critical step for proliferation of various cell types and insulin secretion from pancreatic endocrine cells; however, its role in acinar...
