ABSTRACT
OBJECTIVE:
Dysregulation of covalently closed circular RNAs (circRNAs) has been associated with neurological disorders, the role of circHIVP2 in Parkinson's disease (PD) and its molecular mechanism is not well understood.METHODS:
127 patients with PD and 85 healthy people were enrolled. RT-qPCR was employed to examine the levels of circHIVEP2. ROC curve to explore the diagnostic. Mpp+ induced the SH-SY5Y to construct an in vitro PD cell model. Cell viability, apoptosis, and secretion levels of inflammatory factors were analyzed by CCK-8, flow cytometry, and ELISA assay. CircHIVEP2 targets miRNA predicted by bioinformatics database and validated by the dual luciferase reporter and RIP assays.RESULTS:
CircHIVEP2 was typically lower in PD patients than in controls. CircHIVEP2 has certain specificity and sensitivity to recognize PD patients from healthy individuals. miR-485-3p, a target miRNA of circHIVEP2, was significantly elevated in PD patients. Additionally, MPP+ induction reduced cell viability and promoted apoptosis and inflammatory factor overproduction. However, overexpression of circHIVEP2 significantly inhibited the effects of MPP+, but this inhibition was significantly attenuated by elevated miR-485-3p.CONCLUSION:
circHIVEP2 is a potential diagnostic biomarker for PD, and its upregulation mitigated MPP+-induced nerve damage and inflammation and this may be through targeted by the miR-485-3p.Key words
