“Moreover, RQ-PCR analysis revealed that the enhanced cytotoxic effect of As2O3 in the presence of melatonin is mediated, at least partly, through suppressing the expression of NF-κB anti-apoptotic target genes such as MCL-1, BCL-2, survivin, XIAP, and c-IAP1 in breast cancer cells.”
“Noteworthy, an enhanced induction of apoptosis was found using As2O3 in combination with melatonin.”
