Persian Gulf Snail Crude Venom (Conus textile): A Potential Source of Anti-Cancer Therapeutic Agents for Glioblastoma through Mitochondrial-Mediated Apoptosis.

The results illustrated the significant cytotoxic effect of Conus textile crude venom on U87MG human glioma cells, that inhibits 50% (IC50=10µg/mL) of the cell growth after 12 h of exposure. Viability measurement showed which the Conus textile crude venom is selectively cytotoxic to U87MG human glioma cells, and induced activation of caspase-3 and induction of cell apoptosis via through mitochondrial signaling. Conus textile crude venom also selectively increased mitochondria swelling, ROS formation, cytochrome c release and MMP decrease in cancerous mitochondria but not normal mitochondria. Conclusion; Based on the obtained results from this investigation, it is concluded that the Conus textile crude venom contains promising natural compounds to fight U87MG human glioma cells through activation of apoptosis intrinsic pathways.
