β-elemene down-regulates HIF-lα VEGF and iNOS in human retinal pigment epithelial cells under high glucose conditions

摘要

To investigate the effects and mechanism of β-elemene on the expressions of hypoxia-inducible factor-1α (HIF-lα), vascular endothelial growth factor (VEGF) and inducible nitric oxide synthase (iNOS) in human retinal pigment epithelial (RPE) cells under high glucose conditions.
