Project description:Trabecular meshwork cells in eyes with glaucoma aquire mesenchymal phenotypes. The types of microRNAs in exosomes may differ between static and glaucomatous status and their effects on aqueous humor regulation are still uknown. We used microarrays to identify the differential microRNA expression related to interaction between trabecular meshwork cells and Schlemm's canal endothelial cells.
Project description:The changes in the trabecular meshwork in steroid-induced glaucoma are similar to those in human primary open-angle glaucoma. To explore the changes in the trabecular meshwork in POAG, we extracted RNA from human trabecular meshwork cells with or without dexamethasone, followed by next-generation transcriptome sequencing to observe changes in gene expression in trabecular meshwork cells, thereby better understanding the mechanism of increased IOP.
Project description:Microarray study comparing trabecular meshwork-derived cells (TMDCs) from the iridocorneal angle of the human eye, with other human cell types such as scleral fibroblasts, corneal fibroblasts, retinal pigmented epithelial (RPE) cells, corneal stroma, human embryonic stem cells (hESC), neural precursors differentiated from hESC, human umbilical vein endothelial (HUVEC) cells and human adipose-tissue-derived mesenchymal stromal cells (MSC)

Project description:Glucocorticoids with different chemical structures but similar glucocorticoid receptor potency regulate subsets of common and unique genes in human trabecular meshwork cells. Gene expression changes of human trabecular meshwork cells, TM 86 and TM 93, due to treatment with dexamethasone (Dex), fluocinolone acetonide (FA), and triamcinolone acetonide (TA).
Project description:To clarify the effects of dexamethasone treatment for primary trabecular meshwork cell gene expression, which may relates to the pathophysiology of glucocorticoid-induced glaucoma Three lots (lot #2584, 3423 and 4973) of primary culture human trabecular meshwork (TM) cells were purchased from ScienCell Research Laboratories (Carlsbad, CA). The TM cells were treated with and without 100nM dexamethasone (DEX) for 14 days. Genomewide gene expression analysis was carried out using Agilent 8X60K array.
Project description:Aqueous humor drainage through the trabecular meshwork is regulated in part by hormonal cues, including norepinephrine (NE) and dexamethasone (DEX), and its circadian variation is thought to reflect rhythmic changes in these signals. However, the transcriptional programs and molecular pathways through which NE and DEX influence human trabecular meshwork cells remain incompletely defined. In this study, we performed RNA-seq analysis of immortalized human primary trabecular meshwork cells (abm; T0371) exposed to NE or DEX for 6 hours, with vehicle-treated cells as controls, to identify stimulus-responsive genes and pathways associated with trabecular meshwork function and aqueous humor outflow.
