title: Gas1 is present in germinal niches of developing dentate gyrus and cortex.
abstract: Gas1 is a pleiotropic protein that inhibits cell growth when overexpressed in tumors but during development, it acts as a co-receptor for sonic hedgehog to promote the proliferation and survival of various growing organs and systems. This protein has been extensively studied during development in the cerebellum. However, in other structures of the central nervous system, information concerning Gas1 is limited to in situ hybridization studies. We investigate the pattern of Gas1 expression during various developmental stages of the cortex and dentate gyrus of the mouse brain. The levels of Gas1 decrease in the developing brain and the protein is mainly found in progenitor cells during the development of the cortex and dentate gyrus.
