Abstract
BackgroundEmerging evidence suggests that dysregulated apoptosis might be implicated in the pathogenesis of multiple sclerosis (MS). The aim of the current study was to evaluate the expression of Apoptotic protease activating factor-1 (APAF1) mRNA and its potential regulator miR-484 in relapsing remitting MS patients (RRMS) and to investigate their role as potential disease biomarkers. MethodsAfter Bioinformatic analysis was conducted and revealed miR-484 involvement in the regulation of APAF-1 gene expression. Reverse Transcription-quantitative Real-Time PCR (RT-qPCR) was performed to detect the expression levels of APAF-1 and miR-484 in the peripheral blood mononuclear cells (PBMCs) of 34 RRMS patients recruited from the MS clinic of kasr al ainy hospital- faculty of medicine-Egypt and 34 healthy controls. ResultsAPAF-1 mRNA was significantly downregulated in patients whereas miR-484 expression was upregulated compared to controls (p < 0.01). Sensitivity and specificity of APAF-1 and miR-484 to diagnose MS was (85.3%, 76.5%) and (88.2% and 86.7%) respectively. ConclusionAPAF-1 and miR-484 could play a role as potential MS diagnostic biomarkers. However, absence of a control group of patients with other inflammatory diseases in our study warrants further research to corroborate our findings.
