Upregulation of microRNAs correlates with downregulation of HERV-K expression in Parkinson’s disease
摘要
Human endogenous retroviruses (HERVs) involvement in neurological diseases has been extensively documented, although the etiology of HERV reactivation remains unclear. MicroRNAs represent one of the potential regulatory mechanisms of HERV reactivation. We identified fourteen microRNAs predicted to bind the HERV-K transcript, and subsequently analyzed for their gene expression levels alongside those of HERV-K. We documented an increased expression of four microRNAs in patients with Parkinson’s disease compared to healthy controls, which correlated with a downregulation of HERV-K transcripts. We hypothesize that specific microRNAs may bind to HERV-K transcripts, leading to its downregulation.
