MicroRNAs miR-25, let-7 and miR-124 regulate the neurogenic potential of Müller glia in mice [NanoString]


ABSTRACT: In order to identify the miRNAs in postnatal day 2 (P2) retinal progenitor cells (RPCs), and P8, P11, and adult Müller glia (MG) of the neural retina, we isolated the retinal progenitors from Sox2-CreER: Stopf/f-tdTomato and MG from Rlbp-CreER: Stopf/f-tdTomato mice by means of fluorescent activated cell sorting and analyzed their miRNAs using NanoStrings Technologies®. We next compared miRNA expression of RPCs with MG. We found that most specific miRNAs decline with glial maturation (RPC miRNAs) while others increase (MG miRNAs). Overexpression of miRNA-25 found in RPCs and inhibition of MG miRNA let-7 can induce a neurogenic potential in MG and initiates a de novo differentiation toward neuronal fates.
