Ascorbate acts as a highly potent inducer of chromate mutagenesis and clastogenesis: linkage to DNA breaks in G(2) phase by mismatch repair
Here we examined the role of cellular vitamin C in genotoxicity of carcinogenic chromium(VI) that requires reduction to induce DNA damage. In the presence of ascorbate (Asc), low 0.2–2 μM doses of Cr(VI) caused 10–15 times more chromosomal breakage in primary human bronchial epithelial cells or lung...
