	abstract = {<p>Ruviprase, a 4.4~kDa peptide isolated from Daboia russelii russelii venom demonstrated antiproliferative activity against EMT6/AR1, U-87MG, HeLa and MCF-7 cancer cells with an IC50 value of 23.0, 8.8, 5.8 and 4.0~μg ml(-1), respectively. However, it was nontoxic to non-cancerous human embryonic kidney cell and human peripheral blood lymphocytes. Flow-cytometric analysis confirmed the apoptosis induction in MCF-7 cells by Ruviprase where it induced DNA condensation but did not cause mitotic blockage or chromosomal aberration in treated-cells. Immunofluorescence microscopic analysis indicated Ruviprase induced apoptosis in MCF-7 cells through p53 and p21-mediated pathways. Ruviprase generated reactive oxygen species (ROS), altered the mitochondrial transmembrane potential, and significantly decreased the cellular glutathione (GSH) content of MCF-7 cells. Immunoblotting and quantitative real-time PCR (qRT-PCR) analyses suggested that Ruviprase down-regulated the expression of anti-apoptotic protein Bcl-2, increased cleavage of poly (ADP-ribose) polymerase (PARP) protein, and up-regulated the expression of pro-apoptotic protein Bax, as well as executer protein caspase-7 to induced apoptosis in MCF-7 cells via intrinsic pathway. This is the first report on the characterization of the anticancer potential of a small, non-toxic and anticoagulant peptide purified from Russell{\textquoteright}s viper venom.</p>},
