Microarray analysis of developing mouse cortex reveals regulation of ribosomal protein mRNAs throughout development


ABSTRACT: Neocortical development is spatiotemporally regulated by exogenous factors, but the mechanism regulating timed specificity of neocortical mRNA translation is unknown. We find that active mRNA translation sites (polysomes) contain ribosomal protein subsets that undergo dynamic spatiotemporal rearrangements during mouse neocortical development. Two samples of cortext total RNA each from four embryonic time points were collected.

The mature neocortex is a unique six-layered mammalian brain region. It is composed of morphologically and functionally distinct subpopulations of primary projection neurons that form complex circuits across the central nervous system. The precisely-timed generation of projection neurons from neural stem cells governs their differentiation, postmitotic specification, and signaling, and is critical for cognitive and sensorimotor ability. Developmental perturbations to the birthdate, location, and  ...[more]
