Improved efforts are necessary to define the functional product of cancer mutations currently being revealed through large-scale sequencing efforts. Using genome-scale pooled shRNA screening technology, we mapped negative genetic interactions across a set of isogenic cancer cell lines and confirmed hundreds of these interactions in orthogonal co-culture(More)
The Ll.LtrB intron from the Gram-positive bacterium Lactococcus lactis is one of the most studied bacterial group II introns. Ll.LtrB interrupts the relaxase gene of three L. lactis conjugative elements. The relaxase enzyme recognizes the origin of transfer (oriT ) and initiates the intercellular transfer of its conjugative element. The splicing efficiency(More)
Target identification is a critical step in the lengthy and expensive process of drug development. Here, we describe a genome-wide screening platform that uses systematic overexpression of pooled human ORFs to understand drug mode-of-action and resistance mechanisms. We first calibrated our screen with the well-characterized drug methotrexate. We then(More)
—This paper presents some ideas for visualizing constraint graphs. The motivation for constraint graph visualization is for better understanding and debugging of CP (constraint programming) programs. (Constraint graphs also have the potential for visualizing logic programs such as Prolog programs.) Two important issues in providing good visualization for(More)
In this review, we discuss the use of RNA interference screens to identify genes involved in the regulation and function of membrane proteins. Briefly, cells expressing the membrane protein of interest can be transduced with a pooled lentiviral short-hairpin RNA (shRNA) library containing tens of thousands of unique shRNAs. Transduced cells are then(More)
