Investigation of the expression of long non-coding RNA in Parkinson’s disease

Abstract Background Parkinson’s disease is the second most common age-related neurodegenerative disease after Alzheimer’s. Pathogenic factors in Parkinson’s include inflammation and oxidative stress, which lead to dopaminergic cell apoptosis. The case–control study aims to determine the expression level of long non-coding RNAs (lncRNAs) of the apoptosis pathway in Parkinson’s patients compared to healthy individuals. In the case–control study, 50 patients with Parkinson’s disease were examined, along with 50 healthy individuals matched in age and sex. In both groups, the expression of long non-coding RNAs, including taurine upregulated 1 (TUG1), metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), nuclear-enriched abundant transcript 1 (NEAT1), and growth arrest-specific 5 (GAS5), was compared using real-time polymerase chain reaction (PCR). Results The ratio of MALAT1, NEAT1, and TUG1 gene expression in the case group was statistically significantly higher than in healthy individuals. The ratio of GAS5 gene expression in people with Parkinson’s disease was lower, with a statistically significant difference. The ratio of HULC gene expression was higher in the case group, but it did not show a statistically significant difference with the control group. Conclusion The involvement of long lncRNAs that increase apoptosis may play a role in the pathogenesis of the disease, which may be used for identification and therapeutic purposes.
