Stevioside mediated chemosensitization studies and cytotoxicity assay on breast cancer cell lines MDA-MB-231 and SKBR3

Abstract EN

Cancer is one of the most impacting life-threatening disease for the human populace.

Hence, over the years we have seen a consistent interest to study and investigate new treatments to cure and prevent this disease.

Medicinal plants have played a progressive part in treatment since many years.

In this research study, we have explored the cytotoxicity effect of purified bioactive compound isolated from Stevia rebaudiana leaves and the key mechanism responsible for apoptosis in human breast cancer cells.

The anticancer properties of Stevia rebaudiana leaves has been suggested in earlier literature.

Hence, the aim of this study was to investigate the cytotoxicity of purified stevioside in human breast cancer cell lines MDA-MB-231 and SKBR3.

Results showed that purified stevioside inhibited the growth of cancerous cell lines.

The IC50 obtained after treatment with stevioside on cancer cells MDA-MB-231 and SKBR3 are 55 µM and 66 µM respectively.

This shows purified stevioside is capable of inducing apoptosis indicating its promising anticancer activity.

However, so far chemosensitization effects of stevioside on breast cancer have not been fully explained by other studies.

Hence, additionally, this study also evaluates the chemosensitization potential of stevioside in combination with 5-FU.

This research study shows the importance of Stevia rebaudiana as a good source of bioactive compounds with high anti-cancer property.
