Page 1 Feb.2011 20/20 GeneSystems, Inc. The need for multiplex detection of tissue biomarkers. There is an ever growing demand for increased biomarker analysis in human tissue specimens. Analysis of tissue biomarkers is key to understanding the activation status of particular pathways in specific cell types and can be indicative of disease diagnosis, prognosis, and prediction of therapeutic eff...

Activation of the hedgehog pathway is reported in lung cancer, but its frequency remains unknown. We examine activation of this pathway in lung cancers by in situ hybridization and immunohistochemstry, and find that less than 10% of the tumors have elevated hedgehog target gene expression. We further identify a cell line NCI-H209 and two primary tumors with no detectable Su(Fu), a negative regu...
