Apoptotic related biochemical changes in human amnion cells induced by tributyltin.
Tributyltin (TBT) is one of the environmental pollutants, which is mostly accumulated in marine animals. The toxic effects of TBT have been extensively documented in several types of cells, but the molecular mechanisms responsible for TBT-induced cell damage are still not fully elucidated. The present study was undertaken to evaluate the apoptotic related biochemical changes in human amnion cells induced by TBT. After cells were exposed to TBT at the concentrations of 1-4 microM for 2h, the results suggested that TBT could induce an early and typical apoptosis, moreover caspase-3, the modifications of cytoskeletal structure and the Bcl-2 family were involved in this process. The results will deepen our understanding about the toxic mechanism of TBT on human amnion cells.
