Biomarker for Malignant Breast Cancer Shows Promise for Diagnosis, Therapy, Mayo Clinic, Northwestern University Feinberg School of Medicine and Children's Memorial Research Center Study
Published: May 17, 2012
A collaborative study involving investigators from Mayo Clinic and Children’s Memorial Research Center, Northwestern University Feinberg School of Medicine, led by Mary J.C. Hendrix, PhD and Edith Perez, MD, investigates the clinical significance of Nodal expression in breast cancer. Nodal, a gene that is essential for cellular and structural organization in early development reappears in certain types of aggressive cancers, including melanoma and prostate carcinoma. In the current study, the authors determined the immunohistochemical level of Nodal in breast tissues of over 400 patients previously diagnosed with benign or malignant breast disease. The data reveal that Nodal expression is significantly higher in malignant versus benign breast disease; moreover, the degree of Nodal staining correlates with poorly differentiated, advanced stage and lymph node positive breast cancer. The researchers then treated two human breast cancer cell lines with a Nodal blocking antibody, which significantly reduced proliferation and colony-forming ability. These findings suggest that Nodal can be exploited as a novel prognostic biomarker, and that anti-Nodal therapy may be successfully developed to target breast cancer. The article, published in BioMed Central’s open access journal Breast Cancer Research, was the subject of a commentary and selected as an “Editor’s pick” in the journal.
