Abstract

It was shown that the expression of HIF-1α in retinal pigment epithelium increased under hypoxic conditions. Eight hours after the start of hypoxic exposure, the expression of HIF-1α reached the peak and sustained after 24-hour hypoxia. However, the morphology of PRE cells began to change and the expression of HIF-1α decreased after long-term (48-hour) hypoxia. Hypoxia-induced increase in the level of HIF-1α in RPE. It can be an important step in choriodal neovascularization.
