High-Throughput Sequencing Data Reveal an Antiangiogenic Role of HNF4A-Mediated CACNA1A/VEGFA Axis in Proliferative Diabetic Retinopathy.

ABSTRACT:

Purpose

Proliferative diabetic retinopathy (PDR) is characterized by retinal new vessel formation, pointing to the importance of the antiangiogenic treatment in PDR. Hepatocyte nuclear factor 4A (HNF4A) has been highlighted to inhibit vascular endothelial growth factor (VEGF)-stimulated in vitro angiogenesis. Therefore, this study aims to elucidate the potential antiangiogenic mechanisms of HNF4A in PDR.

Methods

PDR-related high-throughput sequencing datasets (GSE94019, GSE102485, and GSE191210) were obtained from the Gene Expression Omnibus (GEO) database, followed by the screening of differentially expressed genes (DEGs). The protein-protein interaction (PPI) network of the candidate DEGs was constructed based on gene set enrichment analysis (GSEA) data and Search Tool for
