MultiOmyx™ IF assay signaling pathway interrogation

In the United States, colorectal cancer (CRC) is the third most common cancer and the third leading cause of tumor associated death in men and women. CRC is a heterogeneous disease defined by different receptor tyrosine kinase (RTK) activation, signaling through phosphatidylinositol 3-kinase (PI3K)/AKT and RAS/MAP2K pathways. A comprehensive signaling pathway profile analysis may be a critical guide for selecting effective clinical strategies for targeted drugs in combinations or in sequential regimens.
