Abstract

Purpose

Oxidative stress has been implicated in the pathogenesis of various disorders, including diabetic retinopathy (DR). Oxidative stress-responsive apoptosis-inducing protein (ORAIP; a tyrosine-sulfated secreted form of eukaryotic translation initiation factor 5A [eIF5A]) is a recently discovered pro-apoptotic ligand that is secreted from cells in response to oxidative stress and induces apoptosis in an autocrine fashion. This study aimed to determine if ORAIP plays a role in DR.

Methods

To investigate the role of ORAIP in DR, we analyzed the levels of ORAIP in the vitreous body and their relationship with the extent of proliferative diabetic retinopathy (PDR). Enzyme-linked immunosorbent assay was used to quantify the levels of ORAIP, vascular endothelial growth factor (VEGF), C–C motif chemokine ligand 2 (CCL2), interleukin-6 (IL-6), and IL-8 in the vitreous body of 40 eyes from 28 patients with PDR and 11 patients with non-PDR (NPDR). We also analyzed the expression of ORAIP in insoluble proliferative tissues from vitreous body samples by immunofluorescent staining.

Results

The vitreous body concentration of ORAIP was significantly (P = 0.0433) higher in the PDR group (52.26 ± 8.68 [mean ± SE] ng/mL, n = 29) than in the NPDR group (28.21 ± 7.30 ng/mL, n = 11). However, there were no significant correlations between the concentration of ORAIP and those of VEGF, IL-6, CCL2, or IL-8. ORAIP expression was observed in the insoluble proliferative tissues in vitreous body samples of most patients in the PDR group, whereas almost no expression of ORAIP was observed in patients in the NPDR group.

Conclusions

Our findings strongly suggest that ORAIP plays a role in oxidative stress-induced retinal injury and may be a sensitive diagnostic marker and a promising therapeutic target for oxidative stress-induced cytotoxicity.
