Regulation Of Pim1 Under Hypoxia In Prostate Cancer, Eva Sahakian

Loma Linda University Electronic Theses, Dissertations & Projects

A defining characteristic of solid tumors is the capacity to divide and spread under conditions of nutrient deprivation and limited oxygen availability. These microenvironmental stresses arise from structural abnormalities in tumor vessels that lead to aberrant microcirculation. Hypoxia acts as a physiological “selection pressure” in the progression of cancer by activating pathways and enhancing the expression of specific genes in tumor cells which eventually diminish their apoptotic potential. Ultimately, hypoxic microenvironment functions as a “stress factor”, selecting cells with the ability to survive and divide under anoxic conditions. The members of the PIM family of cytoplasmic serine threonine kinases are …
