A Comparative Genome-wide Transcriptome Analysis of Glucocorticoid Responder and Non-Responder Primary Human Trabecular Meshwork Cells
Abstract The genome-wide gene expression analysis of primary human trabecular meshwork (HTM) cells with known glucocorticoid (GC) responsiveness was not reported earlier. Therefore, the purpose of this study was to investigate genes and pathways involved in the GC responsiveness in human trabecular meshwork (HTM) cells using RNA sequencing. A perfusion cultured human anterior segment ex vivo model was utilized to identify the induction of GC-induced ocular hypertension in one eye of a paired eyes after dexamethasone treatment based on the maximum intraocular pressure response and in the contralateral eye, HTM cells were isolated to classify GC-responder and non-responder cells. Some previously reported and unique genes and their associated pathways were identified in HTM cells in response to dexamethasone treatment versus vehicle control and more significantly in GC-responder and non-responder cells. This study will open up the possibility of identifying suitable molecular targets which have the potential to treat GC-induced ocular hypertension/glaucoma.
