Cervical cancer is the second most common type of cancer among women worldwide, for which radiotherapy is a standard treatment. Ferula gummosa Boiss (Apiaceae) is an extremely precious medicinal plant which naturally grows throughout the Mediterranean and Central Asia. The present study examined the cytotoxic effects on HeLa cells from the induction of apoptosis and radiation sensitivity by Ferula gummosa.


HeLa cells were cultured in a RPMI1640 medium, incubated with different concentrations of Ferula gummosa (0-250 µg/ml), and afterwards exposed to 2 Gy γ-rays. The cytotoxicity effect was determined by the MTT assay. Via flow cytometry, apoptotic cells were quantified by apropidium iodide (PI) staining of DNA fragmentation.


Ferula gummosa decreased cell viability in the HeLa cell line in a concentration- and time - dependent manner. Ferula gummosa compared to the control induced a sub-G1 peak in the flow cytometry histogram of treated cells thus indicating that apoptotic cell death is involved in Ferula gummosa-induced toxicity. It was also shown it can sensitize cells to radiation-induced toxicity and apoptosis.


The concurrent use of Ferula gummosa and radiation increases radiation sensitivity and cell death. Therefore, Ferula gummosa can be considered as a potential agent and radiosensitizer in the medical treatment of cancer.
