Project description:Use of microarray analyses to determine the effect of hyperoxia and hypoxia on gene expression in early oxygen-induced retinopathy (OIR).
Project description:To identify the N6-methyladenosine (m6A) modified circular RNAs (circRNAs) involved in a mouse model of oxygen-induced retinopathy (OIR), microarray analysis was performed with the retinal samples from OIR mice and Room air controls.
Project description:Analysis of gene expression changes in oxygen-induced retinopathy mice treated intravitreally with inhibitors. oxygen-induced retinopathy(OIR)mice is one of the experimental systems that mimic retinal ischemic diseases. This model is widely used as an evaluation system for various surgical procedures.
Project description:In order to find out the vital genes during retinal neovascularization (RNV), we set up OIR (oxygen-induced retinopathy; induced with 75%±2% oxygen) and wild-type C57BL/6J murine models. We observed the retinal vascular growth process daily both in OIR and wild-type mice through retinal flat-mount, and isolated total retinal RNA at different time points (P8, P9, P12, P13, P30) both in OIR and wild-type mice for gene expression analysis. At least three different retinae were accessed at each time point for observing the retinal vascular growth process. Ten neural retinae from five mice were harvested and pooled into one sample for gene expression analysis. Three biological replicates were used for each time point. Dye-swaps were performed.

Project description:We aimed at identifying the regulatory network of Aflibercept in the context of pathological neovascularization by using the oxygen-induced retinopathy mouse model as a surrogate of proliferative diabetic retinopathy Total RNA was collected from entire retinal cups dissected from 50-days old mice subjected to the oxygen-induced retinopathy protocol and subsequently injected with Aflibercept either on postnatal days 13 and 15 (OIR+AFLx2) or on postnatal days 13, 15 and 17. Non-injected OIR littermates (OIR) and age-matched mice housed in normoxic conditions (normoxia) were used as controls.

Project description:The purpose of this study is to identify disease-related miRNAs in retinas of a mouse model of oxygen-induced retinopathy (OIR). OIR pups were exposed to 75% oxygen at postnatal day (P)7 for 5 days, and were returned to room air at P12. The miRNAs expression profiles in the retinas from OIR mice at P17 and room air controls were determined through microarray analysis. Expressions of significantly upregulated and downregulated miRNAs in the OIR retinas and controls were confirmed through quantitative real-time RT-PCR (qPCR). Compared to the room air controls, 3 miRNAs were significantly up-regulated, and 8 miRNAs were down-regulated in OIR retinas. Our findings indicated that several miRNAs were differentially expressed in the oxygen-induced retinal neovascularization, which might provide novel therapeutic targets in regulating retinal neovascular diseases.
Project description:To study early and late transcriptional changes introduced to blood and retinal tissue in murine oxygen-induced retinopathy (OIR). From retinal cells RNA was extracted at three time points: immediately after end of hyperoxia (P12), at P17 and P28.
