Popis: More than two decades after the discovery of adult neurogenesis in humans, researchers still struggle to elucidate the underlying transcriptional and post-transcriptional mechanisms. RNA interference is a crucially important process in the central nervous system, and its role in adult neurogenesis is poorly understood. In this work, we address the role of Dicer-dependent microRNA biogenesis in neuronal differentiation of adult neural stem cells within the subventricular zone of the mouse brain. Loss of the Dicer1 gene in the tailless (Tlx)-positive cells did not cause the decline in their numbers, but severely affected differentiation. Thus, our findings identify yet another phenomenon associated with microRNA pathway deregulation in adult neural stem cells which might be of relevance both for neuroscience and clinical practice.
