Radiation-induced accumulation was considerably less in Sf9 even as an analogous ATM/ATR-dependent nuclear translocation was observed following gamma-irradiation and etoposide.     ///    "While its nuclear translocation and ATM/ATR dependence were similar to hp53, the cytoplasmic localization and subdued accumulation following gamma-irradiation indicate functional differences from human cells.. "    ///    "Cells were pre-treated with caffeine for inhibiting ATM/ATR (ataxia-telangiectasia mutated protein/ATM and Rad-3-related protein) activation, wherever required. "
