Role of Ocrelizumab in modulating gene and microRNA expression in multiple sclerosis
Multiple sclerosis is an autoimmune neurodegenerative disease and one of the most significant challenges in modern neurology, impacting approximately 2.8 million people globally. As a multifactorial condition, susceptibility to MS can result from a combination of genetic and environmental factors. Current treatment strategies aim to prevent acute attacks, slow disease progression, and alleviate symptoms. Ocrelizumab, a monoclonal antibody targeting CD20, has demonstrated efficacy in clinical trials by reducing both disease activity and frequency of relapses.
Given the recent approval of this treatment, we investigated whether Ocrelizumab alters the expression of key miRNAs and genes involved in neuroinflammation, such as let-7a-5p, miR-14a-5p, miR-21a-5p, miR-338-3p, IL-1, IL-6, NEAT1, NEFL, NESTIN, SLC16A10 and TNF-alpha, by comparing their expression in patients’ blood before and after one year of treatment with Ocrelizumab. Additionally, we explored potential inverse correlations and direct or indirect interactions among the genes and miRNAs that showed significant changes in expression. Lastly, we conducted a pathway analysis to understand the overall effects potentially exerted by the drug.
Results revealed a significant decrease in the expression of TNF-alpha, SLC16A10, NEFL and IL-6, and an increase in let-7a-5p expression. There was an inverse correlation between let-7a-5p and the four genes, while the genes positively correlated with each other, suggesting let-7a-5p as a common modulator. These findings indicate that further investigation is needed to determine if the drug directly upregulates let-7a-5p, thereby downregulating the four genes, or if these expression changes are an indication of an overall reduction in inflammation.
期刊介绍:
Non-coding RNA Research aims to publish high quality research and review articles on the mechanistic role of non-coding RNAs in all human diseases. This interdisciplinary journal will welcome research dealing with all aspects of non-coding RNAs-their biogenesis, regulation and role in disease progression. The focus of this journal will be to publish translational studies as well as well-designed basic studies with translational and clinical implications. The non-coding RNAs of particular interest will be microRNAs (miRNAs), small interfering RNAs (siRNAs), small nucleolar RNAs (snoRNAs), U-RNAs/small nuclear RNAs (snRNAs), exosomal/extracellular RNAs (exRNAs), Piwi-interacting RNAs (piRNAs) and long non-coding RNAs. Topics of interest will include, but not limited to: -Regulation of non-coding RNAs -Targets and regulatory functions of non-coding RNAs -Epigenetics and non-coding RNAs -Biological functions of non-coding RNAs -Non-coding RNAs as biomarkers -Non-coding RNA-based therapeutics -Prognostic value of non-coding RNAs -Pharmacological studies involving non-coding RNAs -Population based and epidemiological studies -Gene expression / proteomics / computational / pathway analysis-based studies on non-coding RNAs with functional validation -Novel strategies to manipulate non-coding RNAs expression and function -Clinical studies on evaluation of non-coding RNAs The journal will strive to disseminate cutting edge research, showcasing the ever-evolving importance of non-coding RNAs in modern day research and medicine.
