MEDI 9331 Scholarly Activities Clinical Years

Introduction:

Diabetic retinopathy is an ocular condition caused by a multitude of factors as a result of elevated blood glucose. One of the primary mechanisms of damage is a result of oxidative stress. It has been found that levels of IRBP in the vitreous are decreased in the setting of diabetic retinopathy, which could be associated with damage from resulting oxidative stress.

Purpose:

This article will address the protective role of IRBP in diabetic retinopathy by discussing the overexpression and under expression of IRBP and its resulting effect on the retina. Increased levels of IRBP in rats with diabetic retinopathy …

Since the publication of our previous paper, Visual cycle proteins: Structure, function, and roles in human retinal disease (Tsin, et.al, JBC 293:13016, 2018) there has been significant progress on multiple topics discussed in this paper. In the present communication, we further explore research advances on two visual cycle proteins: DES1 and IRBP. In addition, we emphasize the progress of clinical translation of other visual cycle protein research, including the breakthrough of FDA-approved gene therapy for Leber’s congenital amaurosis, and additional gene therapies at different stages of clinical trials for various retinal diseases such as retinitis pigmentosa, diabetic retinopathy, and Stargardt’s …
