Long non-coding RNA NORAD functions as a microRNA-204-5p sponge to repress the progression of Parkinson's disease in vitro by increasing the solute carrier family 5 member 3 expression.
Abstract
Parkinson's disease (PD) is one of the most common neurodegenerative disorders. Long non-coding RNAs have important regulatory values in various human diseases. Non-coding RNA Activated by DNA Damage (NORAD) was reported to regulate PD progression in vitro, but its functional mechanism is fully unknown. We used 1-methyl-4-phenylpyridinium (MPP+ ) to establish the cell-based PD model. NORAD, microRNA-204-5p (miR-204-5p), and solute carrier family 5 member 3 (SLC5A3) levels were quantified using the quantitative real-time polymerase chain reaction. Cell viability and apoptosis were determined by Cell Counting Kit-8 and flow cytometry, respectively. The protein levels were analyzed via western blot. Cytotoxicity was assessed by the released lactate dehydrogenase level in cell supernatant. Oxidative stress and inflammation were measured by the standard indicators. Dual-luciferase reporter and RNA immunoprecipitation assays were performed for intergenic combination. First, we found that NORAD was obviously reduced in MPP+ -treated neuroblastoma cells and lightened the MPP+ -induced cytotoxicity, oxidative stress, and inflammatory response. Then, NORAD was shown to be a miR-204-5p sponge and avoided the injury induced by MPP+ in neur...Continue Reading

Apoptosis
Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
