Mitochondrial DNA Depletion Induces Radioresistance by Suppressing G2Checkpoint Activation in Human Pancreatic Cancer Cells

28 Apr 2009

Abstract excerpt

We hypothesized that mitochondrial function regulates cell cycle checkpoint activation and radiosensitivity. Human pancreatic tumor cells (MiaPaCa-2, rho(+)) were depleted of mitochondrial DNA (rho degrees ) by culturing cells in the presence of ethidium bromide. Depletion of mitochondrial DNA was verified by PCR amplification of total DNA using primer pairs specific for mitochondrial DNA. Loss of mitochondrial...
