d) Representative Immuno-FISH micrographs (using telomere‐specific (CCCTAA) peptide nucleic acid probe and anti-γH2A.X antibody). Arrows indicate co-localization between telomeres and γH2A.X; e) Mean number and % of Telomere-associated DDR foci (TAF). Data are mean±S.E.M. of 3 independent experiments;
