Research Abstract

MicroRNA-124a (miR-124a) is one of the most abundant microRNAs in the central nervous system (CNS). In order to clarify roles of miR-124a in the mature CNS, we are generating floxed miR-124a mice. We established the conditional gene deletion method upon Cre-recombinase expression in the retina and the brain using adeno-associated virus (AAV). Moreover, we identified candidate miR-124a target genes in the brain. The results in the current study contributed to progress of understanding on the miR-124a function in the CNS.
