ULK1 and infection: In the current study, we discovered that the upregulation of miR-142-5p (Accession number: MIMAT0000154) severely stunted neuronal morphogenesis during PHEV infection by targeting the unc-51-like-kinase1 (Ulk1, NCBI Reference Sequence: NM_009469.3) mRNA 3′ untranslated region (3′UTR), which suggested that PHEV largely exploited spatiotemporal control of host microRNAs for neurological disorders.
