Similar to other members of the Pim family (i.e. Pim-1 and Pim-2), Pim-3 can prevent apoptosis and promote cell survival and protein translation, thereby enhancing cell proliferation of normal and malignant cells. Pim-3 is expressed in vital organs, such as the heart, lung, and brain. However, minimal phenotypic changes in Pim-3-deficient mice suggest that Pim-3 may be physiologically dispensable. Pim-3 expression is enhanced in several cancer tissues, particularly those of endoderm-derived organs, including the liver, pancreas, colon, and stomach. The development of hepatocellular carcinoma is accelerated in mice expressing the Pim-3 gene selectively in the liver only when these mice are treated with a hepatocarcinogen, indicating that Pim-3 can act as a promoter but not as an initiator. Moreover, inhibition of Pim-3 expression can retard in vitro cell proliferation of hepatocellular, pancreatic, and colon carcinoma cell lines by promoting cell apoptosis. Furthermore, a Pim-3 kinase inhibitor has been reported to inhibit cell proliferation in an in vivo xenograft model using a human pancreatic cancer cell line without inducing any major adverse effects. Thus, Pim-3 kinase may be a candidate molecule for the development of molecular targeting drugs against cancer. © 2011 Japanese Cancer Association.}, pages = {1437--1442}, title = {Roles of Pim-3, a novel survival kinase, in tumorigenesis}, volume = {102}, year = {2011} }
