Objective: The present study aimed at evaluating the in vitro cytotoxic effect of simvastatin (sv) and alendronate (aln) on squamous cell carcinoma cell line (Hep-2 cells).
Methods: Hep-2 cells were divided into four groups; Control group where cells were cultured in the routine culture medium. Alendronate Group (A) consisting of cells cultured in aln in its IC 50. Simvastatin Group(S) cultured in sv in its IC 50. And finally, a combined group (A+S) comprising cells cultured in combined IC 50 dose of sv and aln. To assess the effect of these drugs on Hep-2 cells, cell viability was measured in addition to measuring vascular endothelial growth factor (VEGF) expression by Elisa.
Results: In all groups, a decrease in the mean viability percentages of the treated Hep-2 cells in relation to control cells was observed in all groups. The combination of both agents exhibited a significant (P-values Ë‚0.05) synergistic effect on decreasing cell viability and angiogenesis of Hep-2 cells in vitro. VEGF measures in all groups were significantly lower than the control group (P-values Ë‚ 0.05). The combination of both drugs at their IC 50 doses can lower the VEGF production by Hep-2 cancer cells (P-values Ë‚ 0.05).
Conclusion: A combination of sv and aln in their Ic50 doses has a dramatic effect on lowering the proliferation and VEGF expression in Hep-2 cancer cells cultured in vitro.
