Description:
During development, cells monitor and adjust their rates of accumulation to produce organs of predetermined size. We show here that central nervous system-specific deletion of the essential adherens junction gene, alphaE-catenin, causes abnormal activation of the hedgehog pathway, resulting in shortening of the cell cycle, decreased apoptosis, and cortical hyperplasia. We propose that alphaE-catenin connects cell-density-dependent adherens junctions with the developmental hedgehog pathway and that this connection may provide a negative feedback loop controlling the size of developing cerebral cortex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556178/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2556178/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lien, Wen-Hui -- Klezovitch, Olga -- Fernandez, Tania E -- Delrow, Jeff -- Vasioukhin, Valeri -- P41 RR011823/RR/NCRR NIH HHS/ -- P41 RR011823-128171/RR/NCRR NIH HHS/ -- R01 CA098161/CA/NCI NIH HHS/ -- R01 CA098161-01A1/CA/NCI NIH HHS/ -- R01 CA098161-02/CA/NCI NIH HHS/ -- R01 CA098161-03/CA/NCI NIH HHS/ -- R01 CA098161-04/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1609-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Human Biology, Fred Hutchinson Cancer Research Center, Seattle, WA 98109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16543460" target="_blank"〉PubMed〈/a〉
