Abstract |
The target and degree of methylmercury cytotoxicity are dose-dependent. Following 6 h exposure to 2.5 - 7.5 microMolar, methylmercury (MeHg) progressively inhibits DNA synthesis and induces chromosomal damage in murine erythroleukemic cells. However, following exposure to 10 - 50 microMolar MeHg, the plasma membrane/cytoplasm complex is grossly perturbed, cell cycle progression is blocked, and chromosomes appear in ring formations. These findings, together with those previously observed following organotin exposure, also suggest that severe and nonspecific toxicity may be a common endpoint of exposure to high levels of organometals. |
