SPION-mediated miR-141 promotes the differentiation of HuAESCs into dopaminergic neuron-like cells via suppressing lncRNA-HOTAIR.

ABSTRACT: In this study, a bioinformatics analysis and luciferase reporter assay revealed that microRNA-141 could silence the expression of lncRNA-HOTAIR by binding to specific sites on lncRNA-HOTAIR. We used superparamagnetic iron oxide nanoparticles (SPIONs) to mediate the high expression of microRNA-141 (SPIONs@miR-141) in human amniotic epithelial stem cells (HuAESCs), which was followed by the induction of the differentiation of HuAESCs into dopaminergic neuron-like cells (iDNLCs). qPCR, western blot, immunofluorescence staining and HPLC all suggested that SPION-mediated overexpression of miR-141 could promote an increased expression of brain-derived neurotrophic factor (BDNF), DAT and 5-TH in HuAESC-derived iDNLCs. The RIP and ChIP assay also showed that overexpression of miR-141 could signifi
