Project description:To identify genes whose expressions in primary human trabecular meshwork (TM) cell cultures are affected by the transcription factor PITX2 and to identify genes that may have roles in glaucoma. Expression profiles derived using microarrays were compared between TM control cells and cells treated with PITX2 siRNAs
Project description:To identify genes whose expressions in primary human trabecular meshwork (TM) cell cultures are affected by the transcription factor PITX2 and to identify genes that may have roles in glaucoma. Expression profiles derived using microarrays were compared between TM control cells and cells treated with PITX2 siRNAs TM1 and TM2 cells were cultured in 6 well plates were transfected with either of two PITX2 specific siRNAs or scrambled siRNA (as control). The scrambled siRNA treatment was performed in duplicate for each TM. Forty eight hours after exposure to siRNAs, cells were harvested and RNA was extracted. Considering the two siRNAs for PITX2 transcription factor, the two scrambled siRNA treatments, and the two TM primary cultures, we performed 8 array hybridizations.
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: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.
Project description:To identify genes whose expressions in primary human trabecular meshwork (TM) cell cultures are affected by the transcription factorfoxc1 and to identify genes that may have roles in glaucoma. Expression profiles derived using microarrays were compared between TM control cells and cells treated with foxc1 siRNAs.
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:we employed RNA-Seq to delineate the TGF-β2 induced changes in the transcriptome of normal primary human trabecular meshwork cells (HTM).
