Innovative Screening Method Uses RNA Interference Technology to Identify "Lethal" and "Rescuer" Genes

New Rochelle, May 16, 2013–Lethal and rescuer genes are defined as genes that when inactivated result in cell death or enhanced cell growth, respectively. The ability to identify these genes in large-scale automated screening campaigns could lead to the discovery of valuable new drug targets. A genome-wide lethality screen that relies on RNA interference technology and led to the validation of 239 gene candidates essential for cell survival is described in ASSAY and Drug Development Technologies, a peer-reviewed journal published from Mary Ann Liebert, Inc., publishers. The article is available free on the ASSAY and Drug Development Technologies website.

A team of researchers led by Bhavneet Bhinder and Hakim Djaballah, Memorial Sloan-Kettering Cancer Center, New York, NY, present their work in the article "An Arrayed Genome-Scale Lentiviral-Enabled Short Hairpin RNA Screen Identifies Lethal and Rescuer Gene Candidates."   

The authors developed a high-stringency analysis method used to determine which genes result in cell death when they are "knocked down." Gene knockdown is achieved via an RNA interference approach, using double-stranded RNA molecules called short hairpin RNAs, or shRNAs. A shRNA binds to a target gene, blocking gene expression. The high-throughput screen is carried out in cells in 384-well microtiter plates.

About the Journal
Assay and Drug Development Technologies is an authoritative peer-reviewed journal published 10 times a year online with Open Access options and in print. It provides early-stage screening techniques and tools that enable identification and optimization of novel targets and lead compounds for new drug development.
