Triple negative breast cancer (TNBC) is difficult to treat due to lack of the three receptors, commonly used for treating breast cancers. Current standard of cure is either ineffective or refractive to many patients. Thus, there is a critical need for alternate, affordable therapies for TNBC cancers. Towards this, electrical pulse-mediated chemotherapy, known as electrochemotherapy is a viable option, because it uses the synergy of electrical pulses and the anticancer properties of chemo drug. Considering the cost and the harsh side effects of various commonly administered chemo drugs, in this study, low cost, yet effective, natural phytochemical curcumin is studied for its anticancer effect on MDA-MB-231, TNBC cells. We applied eight 10 μs, 2500 V/cm or 5000 V/cm pulses with 10 μM concentration of curcumin, and measured cell viability and cytotoxicity. Results indicate that cell survival, as low as 4% was induced by 5000 V/cm pulses, after 72 h, while it was 15% after 24 h. This demonstrates the potential of this treatment for TNBC and the transfer to clinical practice.
