Arsenic Induced Cytotoxicity Study Against Human Epithelial Carcinoma (HeLa) Cell

Abstract

The present investigation was undertaken to find out the cytotoxic effects of various amounts of arsenic exposure to human epithelial carcinoma (HeLa) cell. Cells were treated with a final concentration (0, 10, 20, 30, 40 and 50 µg/l) of arsenite in 5 ml MEM for 24 h where 0 concentration was considered as control. Cell viability was determined by the trypan blue (TB) exclusion test using hematocytometer and automated BIO-RAD TC 10^TM cell counting machine. It was demonstrated that survival rate of cancer cells treated with arsenite (0, 10, 20, 30, 40 and 50 µg/l) for 24 h decreased in a dose-dependent manner. Further, it was revealed that arsenite caused a time-dependent increase in cell death. In the highest concentration of arsenite (50 µg/l) cell survival rate was 1% and 2% in manual and automated counting. The possible mechanism that promote cytotoxicity of arsenite was addressed as oxidative damage of cells.
