DxS is a personalized medicine company that meets the needs of the pharmaceutical industry for biomarkers and companion diagnostics to support the development and sales of cancer and other therapies. The company provides both biomarker products, which are used predominately during clinical trials, and companion diagnostics, which aid doctors in selecting therapies for patients. Working in partnership with drug companies, DxS offer validated biomarker assays to support drug development and then regulatory approval, by identifying likely responders to drug therapies. DxS have launched the world's first cancer mutation companion diagnostic to support Amgen's Vectibix colorectal cancer therapy. DxS kits detect mutations in oncogenes associated with cancer drug response. TheraScreen is the range of CE-marked diagnostic products for detecting mutations in the EGFR and K-RAS genes. Validated biomarker kits are available for research use for EGFR, RAS, RAF, BCR-ABL and other genes that show a correlation between patient mutation status and drug response.

The epidermal growth factor receptor (EGFR) is a member of the HER family receptors and its activation induced by its natural ligand EGF results in colon cancer growth and progression. Panitumumab (pmAb) is a fully human IgG2 anti-EGFR antibody that blocks the EGFR actions. In the present study, we evaluated the effects of pmAb on the EGF-mediated cellular responses in a panel of colon cancer cells (HCT-8, HT-29, DLD-1 and HCT-116). HCT-1116 and DLD-1 cells showed no significant EGF-dependent cell proliferation; HT-29 and HCT-8 exhibited an EGF-dependent proliferation, with HCT-8 cells to be the most responsive with significant EGFR phosphorylation upon treatment with EGF. The effects of pmAb were then evaluated in the most EGF-responsive cells, HCT-8. In that respect, pmAb impedes the signaling cascade mediated by EGFR intracellular phosphorylation and activity of focal adhesion kinase (FAK) as well as the EGF-induced invasive and migratory potential of colon cancer cells. At the level of matrix effectors implicated in colon cancer progression we report that pmAb is a potent inhibitor of constitute and EGF-mediated gene expression of certain matrix effectors, such as membrane-type 1 metalloproteinase (MT1-MMP), extracellular metalloproteinases inducer (EMMPRIN), urokinase plasminogen activator (uPA) and syndecan-4. The obtained data demonstrated that pmAb is a specific blocker of EGF-mediated EGFR activation, resulting in a significant inhibition of colon cancer cell proliferation in early stages of growth, migration and invasiveness as well as of matrix effector implicated in cancer progression.
