Abstract :

Scorpion venoms efficiently block the normal neurotransmitter signaling pathway by prejudicing the ion-channel operating mechanism in the body system. Beside its negative effect, venoms also possess some of the beneficial components for the human being. The venom has also been shown to exhibit anti-cancer properties in various cancer types. This unique property of the venom as anti-cancer agent is mainly due to its role in initiating apoptosis and by inhibiting several signaling cascades mechanism which promote cancer cell proliferation and growth. In this study, we examine the effect of venom on phenotypic changes as well as changes at the molecular levels in colorectal and breast cancer cell lines. A dramatic decrease in cell invasion was observed in both cancer cell lines upon venom treatment. Additionally, there was decrease in IL-6, RhoC, Erk1/2 and STAT3 in venom treated cell lines rendering strong messages of its anti-cancer properties. Furthermore, decrease in the expression of anti-apoptotic proteins and also up-regulation of pro-apoptotic proteins by these lines were observed upon venom treatment. Moreover, a vivid picture of DNA damage was also detected upon venom treatment. In conclusion, the scorpion venom possesses significant potential as an anti-cancer agent against colorectal (HCT-8) and breast cancer (MDA-MB-231) cell lines.
