Abstract

Este estudo teve como objetivo avaliar os efeitos da morina em complexos cúmulo-oócito (COC) suínos, quando adicionada em diferentes concentrações no meio de maturação in vitro (MIV). Os COC suínos foram maturados in vitro em um meio base (grupo controle) e com 5, 10, 50 e 100 µM de morina. A viabilidade, as taxas de maturação nuclear e os níveis de espécies reativas de oxigênio (ROS) foram avaliados nos oócito; a apoptose das células do cúmulo foi medida por citometria de fluxo. Os níveis de progesterona do meio de MIV em 22h e 44h foram medidos por imunoensaio de micropartículas quimioluminescente. A adição de morina durante a MIV não afetou a viabilidade dos oócitos. A exposição a 50 µM e 100 µM de morina no meio de maturação diminuiu significativamente a maturação nuclear dos oócitos. Os níveis de progesterona no meio de MIV aumentaram significativamente em todos os grupos experimentais entre 22h e 44h. A adição de 100 µM de morina diminuiu significativamente a produção de progesterona em 22h e 44h de incubação. Os níveis de ROS nos grupos de 5 µM e 10 µM foram significativamente menores do que no controle. A morina modifica significativamente o perfil de apoptose e afeta a viabilidade das células do cúmulo. A morina atua como um antioxidante e possui efeitos tanto benéficos quanto prejudiciais nos oócitos suínos de maneira dose-dependente.
