Popis: Macrovipera lebetina obtusa (MLO) is a venomous snake endemic to Middle East. Here we describe the therapeutic potential of the MLO snake venom. In S-180 sarcoma-bearing mouse model, we showed that the MLO snake venom inhibits tumour growth by 50%. In human dermal microvascular endothelial cells (HMVEC-D), treatment with the MLO snake venom lead to an increase of expression levels of the vascular endothelial growth factor (VEGF), while the level of the expression of caspase 8 did not change. In HMVEC-D cells MLO snake venom induces necroptosis, rather than apoptosis. In the chick embryo chorioallantoic membrane (CAM) assay, exposure to MLO snake venom inhibited bFGF-induced angiogenesis by 22%. Taken together, these results indicate that the MLO snake venom has a potent cytotoxic activity. Regulated necroptic cell death pathway, which is engaged by MLO snake venom, may become a promising novel target for antitumor therapies.
