Neural progenitors and stem cells: mechanisms of progenitor heterogeneity.

abstract：:The PTEN tumor suppressor gene is a lipid phosphatase that negatively regulates cell survival mediated by the phosphatidyl inositol 3' kinase-protein kinase B/Akt signaling pathway. Recent in vivo studies have revealed a novel role for PTEN in the size control of neurons. Dysregulation of cell growth control by PTEN i...

abstract：:The plasticity of the nervous system is due to the ability of neurons to change their properties by altering the function of their proteome. A major mechanism for this is through altering the amount of proteins by regulating their translation. In this review, we focus on recent advances in the elucidation of the mecha...
