Time-dependent Glucocorticoid-Induced Transcriptomic Changes in Human Trabecular Meshwork and Schlemm’s Canal

Abstract Purpose To identify the transcriptomic changes induced by dexamethasone (DEX) in trabecular meshwork (TM) and Schlemm’s canal endothelial (SCE) cells with RNA-sequencing (RNA-seq). Methods Human TM (n=10) and SCE cell strains (n=5) were isolated from healthy donor eyes and exposed to DEX 100nM and vehicle (control). Three DEX exposure times were evaluated: 1-hour, 6-hours, and 2 days. RNA-seq was performed on Illumina’s TruSeq platform and gene expression was quantified using featureCount. DESeq2 paired (treated and untreated) sample test was applied to identify genes transcriptionally responsive to DEX (DEGs) at false discovery rate
