Detection of genomic DNA damage induced by X-ray irradiation or H2O2 treatment. (A) Representative images of immunofluorescence staining of γH2AX (red spot) in HF-TERT cells, before (CTRL) and after X-rays irradiation (X-rays). (B,C) Graphs evidencing data about the frequency of γH2AX after irradiation and hydrogen peroxide treatment. Bars correspond to standard error of γH2AX. Statistical analysis is performed between HFFF2 and HF-TERT cells. * p < 0.05; ** p < 0.01 by t-test.
