| Research Abstract |
Molecular mechanism of cell death induced by ionizing radiation, heat or ultrasound was examined. Stable knockdown of TAK1 caused increase in subG1 fraction and apoptosis induced by X-rays in HeLa cells. Inhibition of DNA-PK increased heat-induced apoptosis in HeLa cells and the knockdown of an identified gene, NR1D1, also enhanced apoptosis. For the cell death induced by ultrasound, cell death signal is modulated by the balance between p53 and Akt via ATM and DNA-PK and the pathway of DNA-PK/Akt is predominant in sonicated cells.
