[miR-9: a key factor of the physiopathological regulation of the neural progenitor state].

Abstract

microRNA are small non-coding RNA that modulate gene expression post-transcriptionally. Discovered 20 years ago, their individual functions start to be unraveled. Collectively, functional studies point to an important functional plasticity of microRNA, along the course of evolution, and across different cellular contexts. This is the case in particular for one of them, miR-9, a key factor of the regulation of the neural progenitor state in Vertebrates.
