Dexrazoxane 0-5 H2A.X variant histone Mus musculus 189-198 25609833-8 2015 DXR treatment for 24 h increased gammaH2AX phosphorylation, specifically increasing the number of foci-positive granulosa cells in antral follicles, while Dexra pretreatment inhibited DXR-induced gammaH2AX phosphorylation foci formation. Dexrazoxane 155-160 H2A.X variant histone Mus musculus 196-205 17875725-5 2007 In the present study, we showed that dexrazoxane specifically abolished the DNA damage signal gamma-H2AX induced by doxorubicin, but not camptothecin or hydrogen peroxide, in H9C2 cardiomyocytes. Dexrazoxane 37-48 H2A.X variant histone Mus musculus 94-104
