Abstract

Cancer stem cells (CSCs) are chemoresistance and could be a preferential target for reversing resistance. Doxorubicin is one of the most effective chemotherapy agents, but resistance still occurs. Doxorubicin generates reactive oxygen species (ROS). The increased specific activity of MnSOD has been suggested as one possible mechanism for breast cancer stem cells (BCSCs) to maintain stemness and survival. The study performed to determine the effect of andrographolide on oxidative status and its relation to the viability of BCSCs given repeated doxorubicin. CD24-/CD44+ BCSCs were grown in DMEM/F12 medium with 0,1µM doxorubicin for 14 days, then treated with a combination of 0,1µM doxorubicin and 0,285 mM andrographolide until day 22. MnSOD activity was suppressed on day 4 when BCSCs were still sensitive to doxorubicin treatment. Viability significantly increased on day 20 along with increased MnSOD activity. Andrographolide restored the sensitivity of BCSCs to doxorubicin, which correlated with MnSOD activity but not catalase. There was no change in MDA levels in all days of treatment which means BCSCs can maintain oxidative stress level. Andrographolide supplementation can decrease MnSOD activity but not catalase and is closely related to decreased cell viability with low sensitivity to doxorubicin.
