Bryonia aspera Root Extracts Induce Programmed Cell Death in Selected Cell Lines of Glioblastoma, Ovarian, and Breast Cancer

Background. Medicinal plants have been remarkable sources of current chemotherapeutic agents. Ethnobotanical utilization of Bryonia species goes back to the old era, and contemporary but preliminary studies have evidenced the anticancer effects of this kind of plant. Methods. The MTT assay was used to investigate the cytotoxicity of a range of concentrations from different extracts of Bryonia aspera root in cancer and noncancer cells. The apoptosis was assessed using annexinV-FITC/PI flow cytometry assay. The expression of selected hallmark genes from different cell death modalities, including apoptosis, necroptosis, ferroptosis, and pyroptosis, was investigated using the qPCR method. The ROS production was also measured by the fluorescence technique. Results. Compared to the normal cells, all three extracts could induce significant cell death in lower doses in breast, ovarian, and glioblastoma cancer cells. Flow cytometry and gene expression studies revealed that different extracts of Bryonia aspera tend to induce different types of cell death in the selective cancer cell lines. ROS production was not impacted significantly by any of those three extracts in none of the cancer cells. Conclusion. The findings showed that all three extracts of Bryonia aspera root contain biologically active compounds that induce different types of programmed cell death in the investigated breast, ovarian, and glioblastoma cancer cells in concentrations significantly less than the doses affecting normal cells.
