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

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. Oxidative stress induced lncRNAs expression in human trabecular meshwork cells were measured at 2 hours after exposure to doses of 300mM.
