DNA Double-Strand Breaks by Cr(VI) Are Targeted to Euchromatin and Cause ATR-Dependent Phosphorylation of Histone H2AX and Its Ubiquitination
Hexavalent chromium is a human respiratory carcinogen that undergoes intracellular activation in vivo primarily via reduction with ascorbate. Replication of Cr-adducted DNA triggers mismatch repair that generates toxic DNA double-strand breaks (DSBs) as secondary lesions. Here, we examined the intra...
