Long non-coding RNA RP11-820 promotes extracellular matrix production via regulating miR-3178/MYOD1 in human trabecular meshwork cells

Project description:To further explore t of the role lncRNAs in glaucoma patients, we have employed lncRNAs microarray expression profiling as a discovery platform to identify abnormal genes under oxidative stress in HTMCs. Our results revealed that lncRNA-RP11 was significantly up-regulated under oxidative stress in HTMCs. Further studies found that lncRNA-RP11-820 directly binds miR-3178, through which regulates the expression of MYOD1. Importantly, MYOD1 can transcriptionally activate ECM genes. Furthermore, MYOD1 binds STAT3 to form a transcription complex, and transcriptionally activates ECM genes expression in HTMCs. Taken together, our data established taht oxidative stress induced lncRNA-RP11-820 plays a key role in regulating miR-3178/MYOD1/ECM axis in HTMCs.

Trabecular meshwork cell-derived exosomal microRNA expression

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.

Transcription profiling of human trabecular meshwork cells after TGF-beta1 and 2 treatment

Project description:TGF-beta levels are known to increase in the aqueous humor of eye cells in patients with glaucoma. Increase TGF-beta is assumed to have a biochemical impact on the trabecular meshwork, and an increase in extracellular matrix formation, which may be responsible for decrease outflow facility of the eye. This may increase extracellular pressure, causing glaucoma. TGF-beta 1 may be the cause of abnormal accumulation of extracellular matrices in trabecular meshwork of eyes with primary open angle glaucoma. Transforming growth factor (TGF)-beta2 regulates the expression of proteoglycans in aqueous humor from human glaucomatous eyes. To identify gene expression changes as a result of TGF-beta1 and 2 treatment of human trabecular meshwork cells. We expect to see a change in expression of the proteoglycans in HTM cells as a response to TGF-beta treatment. Human Trabecular Meswork cells in the eye were bathed by aqueous humor. TM cells were removed from individuals with the following ages: 16,66,67,73, and 76. Each individual was treated with EtOH (control), TGF-beta1, or TGF-beta2. Total RNA from each individual was pooled for each chip. Technical replicates were created for each treatment type, for a total of 6 chips.

Effects of dexamethasone for primary trabecular meshwork cell gene expression

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.
