Radiation enhanced mitochondrial mTOR and mitochondrial respiration in other human cancer cells.

<p>(A) Human colon cancer HCT116 and (B) brain tumor U87 cells were irradiated or sham irradiated with IR and collected at indicated time points. Mitochondrial ATP production and oxygen consumption were measured to determine the enhancement of mitochondrial functions after radiation. (C) Western blotting of mitochondrial fractions of HCT116 and U87 were performed to detect mTOR localization at time points shown after radiation. Data are mean ± SEM, p-values were included in each data.
