Gene expression of heat shock protein (HSP 105) in MCTS cultures treated by E. scaber, tamoxifen citrate, and their combinatorial treatment as measured by real-time quantitative PCR. E. scaber ethanol extract 60 μg/mL (ES60), tamoxifen citrate 3.125 μg/mL (TC3), and tamoxifen citrate 6.25 μg/mL (TC6). The results are expressed as fold change relative to the untreated control group. Data are presented as means ± SEM of three independent experiments. ∗Statistical significance () between control cells and treatment groups.
