Ventana Medical Systems, Inc. develops first-ever fully automated dual-stain technique for miRNA and protein detection in cancer
Date:9/6/2012

TUCSON, Ariz., Sept. 6, 2012 /PRNewswire/ -- Ventana Medical Systems, Inc. (Ventana), a member of the Roche Group, is introducing a first-of-its-kind fully-automated staining technique that will allow researchers to examine miRNAs and proteins related to cancer in the same section of tumor tissue. Detecting miRNAs and proteins together, in the context of the tumor microenvironment, allows researchers to visualize the association of oncogenic protein expression to those miRNAs involved in the regulation of the mRNA species responsible for protein production. This is exciting news for researchers who have been studying how this relationship plays a role in driving tumor cell growth in many tumor types including breast, lung, prostate and colorectal cancers.

Dr. Thomas Grogan, M.D., pioneering pathologist and founder of Ventana Medical Systems, Inc., is highly optimistic about the promise of this technique. "With this exciting technical breakthrough, we can now judge with a standard light microscope the link between miRNA and associated proteins in full cellular context. It will now reveal matters like message/protein dysfunction and heterogeneity. This then will add greatly to our understanding of the mechanisms of cancer biology and help direct new better informed targeted therapies."

James W. Welsh, M.D., assistant professor in the Department of Radiology at The University of Texas MD Anderson Cancer Center, believes this new technology could eventually work as a companion diagnostic tool for future miRNA pathway targeting drugs. "For the first time, using this technique, researchers will be able to observe the relationships between specific miRNAs and their known oncogenic protein targets," says Dr. Welsh. "In lung cancer, we've begun to identify pairs of miRNAs and proteins that we believe play a role in treatment resistance and metastasis; utilizing this new protocol will hopefully allow us to better und
