| Popis: | During retinal development, a physiologic hypoxia stimulates endothelial cell proliferation. The hypoxic milieu warrants retina vascularization and promotes the activation of several mechanisms aimed to ensure homeostasis and energy balance of both endothelial and retinal cells. Autophagy is an evolutionarily conserved catabolic system that contributes to cellular adaptation to a variety of environmental changes and stresses. In association with the physiologic hypoxia, autophagy plays a crucial role during development. Autophagy expression profile was evaluated in the developing retina from birth to post-natal day 18 of rat pups, using qPCR, western blotting and immunostaining methodologies. The rat post-partum developing retina displayed increased active autophagy during the first postnatal days, correlating to the hypoxic phase. In latter stages of development, rat retinal autophagy decreases, reaching a normalization between post-natal days 14-18, when the retina is fully vascularized and mature. Collectively, the present study elaborates on the link between hypoxia and autophagy, and contributes to further elucidate the role of autophagy during retinal development. |
