“In this study, we showed that, indole-3-carbinol (I3C), a natural product found in broadly consumed plants of the Brassica genus, could block the cytotoxic effects of dexamethasone (Dex), and elucidated the underlying molecular mechanisms.”
“Moreover, exposure to Dex triggered a rapid onset and time-dependent superoxide overproduction in osteoblastic cells, which was effectively suppressed by addition of I3C.”
“Taken together, I3C can reverse cytotoxicity of Dex through blocking ROS overproduction and enhancement of Nrf2 expression.”
“Treatment of the cells with Dex resulted in activation of caspase-3/-8/-9 and subsequent cleavage of PARP, which was also effectively blocked by co-incubation of I3C.”
