ABSTRACT
In the spectrum of breast neoplasms, approximately 15 to 20% of all diagnosed cases are triple-negative breast carcinoma. TNBC grows and spreads faster than other invasive breast cancers and has a worse prognosis. The existing therapies and chemotherapeutic drugs have several limitations, so the development of safe and affordable treatment options is currently in demand. Hence, this research focuses on scientifically evaluating the therapeutic anticancer effect of ethyl acetate extract of MSG and its combined efficacy with doxorubicin against TNBC. MSG has shown an IC50 value of 48.40 ± 1.68 µg/ml on the MDA-MB-231 cell line, and the combination of MSG with Dox demonstrated the synergistic effect. Apoptotic changes such as membrane blebbing chromatin condensation were observed in MSG alone and in combination with doxorubicin treatments. Apoptosis was confirmed with Annexin V-FITC/PI staining and increased apoptotic markers such as Cleaved caspase-3 Bax and decreased anti-apoptotic markers Bcl-2 by western blotting. The tumor burden significantly decreased in MSG and combination treatment groups while restoring their body weights. Meanwhile, the Dox-treated group indicated a decreased tumor burden combined with weight loss. The present investigation revealed that MSG and doxorubicin have a synergistic anticancer effect in TNBC.
