Inhibitory effect of Milk thistle seed extract on cadmium chloride induced DNA damage in liver cells
Cadmium (Cd) is a biologically non-essential but economically valuable metal. Its increase in the environment has been linked to various diseases such as diabetes, organs failure, bone damage, endocrine hormone imbalance and cancer in humans and animals. Cd mainly accumulates in the liver and lead to its malfunction. In the present paper, we investigated the inhibitory effect of mcomet assays were used to evaluate double and single breaks in DNA. The treatment of the cells with CdCl2 alone resulted in dose dependent decrease in cell viability compared to control cells; while cells co-treated with MTS increased cell viability. Furthermore, treatment of the cells with CdCl2 alone caused increase in DNA damage as shown by the % DNA in the tail and olive tail moment in both alkaline and neutral comet assays. Co-treatment with MTS inhibited the Cd-induced DNA damage as shown by the decreased % DNA in the tail and olive tail moment. Our results clearly showed the inhibitory effect of MTS on Cd-induced DNA damage in rat liver cells.Silybum marianum) on cell death and DNA damage induced by cadmium chloride (CdCl2) in rat liver cells.
