Avaliação do efeito citotóxico e apoptótico induzido pela ação dos venenos do gênero Bothrops e Tityus em linhagens de carcinoma cervical transformadas por papilomavírus humano. 2015. 70f. Dissertação (Mestrado em Ciências Farmacêuticas) - Centro de Ciências da Saúde, Universidade Federal do Rio Grande do Norte, Natal, 2015.https://repositorio.ufrn.br/jspui/handle/123456789/21709Among the types of cancer incidents in Brazil, cervical cancer is the fourth most common type among women, with more than 99.7% of cases associated with infection by human papillomaviruses (HPV) types 16 and 18 mainly. The limited of malignant tumors to conventional chemotherapy response led to the development of new pharmacological strategies based on knowledge of new therapeutic targets. Considering the diversity of scorpions and snakes of Brazilian fauna, these poisonous animals have a pharmacological potential in their venom, being of great interest in the new drugs research and development from raw or fractions poison. Thus, faced with these poisons opens an expectation in the search for new compounds with therapeutic action in the treatment of cancer. The objective of this study was to evaluate the cytotoxic effect and apoptosis of the poisons of the scorpion Tityus serrulatus (TSR), Bothrops jararaca (BJ) and Bothrops erythromelas (BE) in cervical carcinoma cell lines SiHa and HeLa, tranform by the respective HPV 16 and 18. In relation to cell viability by MTT method was obtained challenged cytotoxicity in tumor cell lines with the poisons of snakes BJ and BE compared to the TSR poisons. Similarly, the process of cell death was greater when challenged with BJ and BE. Therefore, Bothrops poisons showed a cytotoxic and apoptotic action on the lines studied, dose-dependent and time-response manner. This study suggests for the first time, a cytotoxic and apoptotic role of poisons of snakes B. jararaca and B. erythromelas in cervical carcinoma cell lines.Acesso AbertoCâncer cervicalPapilomavírus humanoCitotoxicidadeTityus serrulatusBothrops jararacaBothrops erythromelasmasterThesisCNPQ::CIENCIAS DA SAUDE::FARMACIA
