Description:
Retroviral short hairpin RNA (shRNA)-mediated genetic screens in mammalian cells are powerful tools for discovering loss-of-function phenotypes. We describe a highly parallel multiplex methodology for screening large pools of shRNAs using half-hairpin barcodes for microarray deconvolution. We carried out dropout screens for shRNAs that affect cell proliferation and viability in cancer cells and normal cells. We identified many shRNAs to be antiproliferative that target core cellular processes, such as the cell cycle and protein translation, in all cells examined. Moreover, we identified genes that are selectively required for proliferation and survival in different cell lines. Our platform enables rapid and cost-effective genome-wide screens to identify cancer proliferation and survival genes for target discovery. Such efforts are complementary to the Cancer Genome Atlas and provide an alternative functional view of cancer cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2981870/" 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/PMC2981870/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schlabach, Michael R -- Luo, Ji -- Solimini, Nicole L -- Hu, Guang -- Xu, Qikai -- Li, Mamie Z -- Zhao, Zhenming -- Smogorzewska, Agata -- Sowa, Mathew E -- Ang, Xiaolu L -- Westbrook, Thomas F -- Liang, Anthony C -- Chang, Kenneth -- Hackett, Jennifer A -- Harper, J Wade -- Hannon, Gregory J -- Elledge, Stephen J -- F31 NS054507-01/NS/NINDS NIH HHS/ -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-36/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 AG011085/AG/NIA NIH HHS/ -- T32CA09216/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Feb 1;319(5863):620-4. doi: 10.1126/science.1149200.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Genetics, Center for Genetics and Genomics, Brigham and Women's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18239126" target="_blank"〉PubMed〈/a〉
