dc.description.abstract | Consumption of areca nut containing principal alkaloid arecoline is a major contributor to oral cancer in India. In this study, we have investigated the role of arecoline in mitochondrial dysfunction and propose Bacopaside-I (BS-I), a saponin from Bacopa monnieri, to target the inflammatory effect of arecoline for oral cancer therapeutics. Increased mitochondrial fusion and ROS are found in arecoline-treated conditions compared to control in Cal33 cells. Additionally, arecoline contributes to the NLR family pyrin domain containing 3 (NLRP3) inflammasome activation in Cal33 cells. Inhibition of mtROS by Mito-Tempo suppressed the arecoline-mediated NLRP3 inflammasome activation. BS-I induces mitochondrial fission through the PPA2-DRP1 axis and activates PINK1-PARKIN mediated mitophagy to eliminate the dysfunctional mitochondrial population in Cal33 and FaDu cells. BS-I-induced mitophagy is compromised in parkin-deficient conditions, whereas mitochondrial fission is still evident in Hela Cells. BS-I further hinders arecoline-induced mitochondrial ROS production and NLRP3 inflammasome activation in Cal33 cells. Inhibition of mitochondrial fission through Mdivi1 and mitophagy through CQ and siPARKIN significantly hampers the inflammasome inhibition by BS-I. These results established that BS-I-induced mitochondrial fission and mitophagy help segregate and remove damaged mitochondrial sub-population, contributing to NLRP3 inflammasome inhibition in oral cancer cells. | en_US |
