Abstract

From ancient times to the present-day animal venoms had been used as medicinal and therapeutic agents. Recently it has been reported that the scorpion venom is a potential source of active and therapeutic compounds to design potent drugs against variety of cancerous cells and other diseases. The current study aimed to evaluate the selective toxicity of Iranian Mesobuthus eupeus (IMe) crude venom as a potential source of anticancer compounds on cancerous CLL B-lymphocytes and normal lymphocytes. For this purpose, we isolated cancerous CLL B-lymphocytes and normal lymphocytes from chronic lymphocytic leukemia patients and healthy volunteers. Cancerous CLL B-lymphocytes and normal lymphocytes were treated with different concentration (0, 5, 10, 20, 40 and 80 µg/ml) of IMe crude venom for 12 hours and cytotoxicity, reactive oxygen species (ROS) production, collapse of mitochondrial membrane potential (MMP) and lysosomal membrane integrity were determined. The data demonstrated the significant cytotoxic effect of IMe crude venom on cancerous CLL B-lymphocytes, with a concentration value (IC50) that inhibits 50% of the cell viability of 60 µg/ ml after 12 h of incubation. MTT assay proved that the IMe crude venom is selectively toxic to cancerous CLL B-lymphocytes, and IMe crude venom induced selective cell death via activation of ROS formation and mitochondrial/lysosomal dysfunction. These finding showed that IMe crude venom has a selective mitochondrial/lysosomal-mediated cell death effect on cancerous CLL B-lymphocytes. Therefore, the IMe crude venom and its fractions may be promising in the future anticancer drug development for treatment of CLL and variety of cancers.
