Cytotoxic mechanism of Bothrops jararaca venom mediated by mitochondrial depolarization

Background: Snake venoms are natural sources of proteins and peptides with several biological activities. Therefore, this study aimed to evaluate the in vitro toxicity of crude Bothrops jararaca (B. jararaca) venom on different human tumor cells and investigate its action mechanism. Material and methods: The crude venom from B. jararaca was provided by State Foundation for Health Research and Production and Center of Toxicological Information of Rio Grande do Sul, Brazil. To investigate different sensitivities of normal and cancer cell lines, cell viability was measured by using the MTT and neutral red uptake assays.
