The differences of the cytogenotoxicity and proteins expression of human B-cell lymphoblastoid cells exposed to cigarette smoke condensates (CSCs) from two kinds of cigarettes were detected with CCK-8 assay, comet assay, protein microarray and western blot assay in vitro. Human B-cell lymphoblastoid cell line was exposed to CSCs from two cigarettes (which delivers approximately 3mg tar, 0.3mg nicotine,...
Cigarette smoke condensates (CSCs) are complex mixed compounds that contain both direct and indirect mutagens/carcinogens. To detect genotoxicity of CSCs in vitro, a combination of various enzymes (e.g. activation and detoxification enzymes) called S9 is usually added. However, as S9 may induce cytotoxicity in target cells, it is unclear whether the addition of S9 can impact CSC-induced toxicity....
DNA damage of peripheral lymphocytes in 60 workers occupationally exposed to trivalent chromium [Cr(III)] in a tannery was studied using comet assay. The urinary and blood chromium levels were detected as a biomarker of internal exposure. The 90 subjects were divided into three groups: (i) exposure group I included 30 tannery workers highly exposed to chromium from tanning department; (ii) exposure...
