“…The captive reproduction of Crotalus durissus terrificus is an important practice once their venom is a natural source of bioactive substances with therapeutic potential, such as antitumoral properties, as well as for antiophidic serum production (Cura et al, 2002;Soares et al, 2010;Calvete et al, 2011;Kumar et al, 2014;Nudel et al, 2012). The search for new drugs has indicated toxins from Crotalus durissus terrificus venom as inhibitors of cell adhesion, cell migration, epidermal tumor growth factor, metastases induced in experimental mice models, and use of some specific proteins for production of drugs (Cura et al, 2002;Cunha et al, 2015;Neves et al, 2015;Reeks et al, 2015).…”
