Researchers use RNAi libraries to identify regulators of apoptosis and chemoresistance

When it comes to the deadly skin cancer melanoma, studying functional tissue rather than cell lines may better provide insight into the disease's development, according to new research from a Howard Hughes Medical Institute predoctoral fellow at Stanford University School of Medicine. . Though multiple genetic alterations are associated with melanoma development, scientists have not been able to...

New RNAi tools enable systematic studies of gene function

An international public-private research team led by scientists at the Broad Institute of MIT and Harvard announced today the construction and availability of an extensive library of molecular reagents to silence most human and mouse genes. . As described in the March 24 issue of Cell, this library consists of small RNA molecules that can switch off genes individually, allowing the user to dissec...

Tool developed to silence genes in specific tissues using RNAi

Researchers at The University of Texas M. D. Anderson Cancer Center say they have jumped a significant hurdle in the use of RNA interference (RNAi), believed by many to be the ultimate tool to both decode the function of individual genes in the human genome and to treat disease. . .. Previously reported approaches to achieve this were either technically cumbersom...

For Stanford scientists, RNAi gene therapy takes two steps forward, one step back

Three years ago Mark Kay, MD, PhD, published the first results showing that a hot new biological phenomenon called RNA interference was an effective gene-therapy technique in mice. That finding kicked off an RNAi gene therapy research flurry amongst both academic and industry research groups. . Now, with three human RNAi gene therapy trials under way, Kay's initial excitement is proving to be on...

RNAi shows promise in gene therapy, Stanford researcher says

Three years ago Mark Kay, MD, PhD, published the first results showing that a biological phenomenon called RNA interference could be an effective gene therapy technique. Since then he has used RNAi gene therapy to effectively shut down the viruses that cause hepatitis and HIV in mice. . With three human RNAi gene therapy trials now under way - two in macular degeneration and one in RSV pneum...
