WebNov 3, 2024 · We first determined the time point at which cisplatin induces H2AX phosphorylation in ovarian cancer cells. γH2AX at S139 is a well-established marker of DNA breaks, including those that arise during the processing of platinum adducts by different repair pathways ( 20 ). WebApr 15, 2009 · Conclusion: Cisplatin has long-term effects on the early double-strand break response of γ-H2AX and Rad51 foci formation after ionizing radiation. Inhibition of sensing and processing of double-strand break by γ-H2AX and Rad51 foci formation are important mechanisms by which cisplatin can alter the radiation response. Translational Relevance
