Cytotoxic and antiproliferative effects of hellebrin on breast and lung cancer cells

This study aimed to investigate the impact of hellebrin on human lung cancer cell (H1299) and breast cancer cell (MCF-7) lines over time. The viability of various concentrations of hellebrin (100 nM-400 nM) on two cancer cell lines was measured using the MTT method. The cellular proliferation over time was examined using xCELLigence real-time cell analysis (RTCA). The results showed a significant decrease in cell viability with increasing concentrations of hellebrin in both cancer cell lines compared to the control group (p˂0.0001). While the viability of both cancer cells decreased after a certain period of hellebrin application, the viability of the control groups increased over time. These findings indicate that hellebrin has high antiproliferative and cytotoxic effects on breast and lung cancer cells. Consequently, this study suggests that hellebrin may have potential as a treatment for other cancers, especially lung cancer, and further in vitro and in vivo experiments are needed to investigate this possibility.
