MiR-130a-3p regulates neural stem cell differentiation in vitro by targeting Acsl4.

ABSTRACT: In the adult mammalian brain, neural stem cells (NSCs) are the precursor cells of neurons that contribute to nervous system development, regeneration, and repair. MicroRNAs (miRNAs) are small non-coding RNAs that regulate cell fate determination and differentiation by negatively regulating gene expression. Here, we identified a post-transcriptional mechanism, centred around miR-130a-3p that regulated NSC differentiation. Importantly, overexpressing miR-130a-3p promoted NSC differentiation into neurons, whereas inhibiting miR-130a-3p function reduced the number of neurons. Then, the quantitative PCR, Western blot and dual-luciferase reporter assays showed that miR-130a-3p negatively regulated acyl-CoA synthetase long-chain family member 4 (Acsl4) expression. Additionally, inhibition of Acsl
