About
Brief Description: UCLA researchers in the Division of Digestive Disease in the Department of Medicine at the David Geffen School of Medicine, led by Drs. Charalabos Pothoulakis and Dimitrios Iliopoulos, have identified several biomolecules that are potential diagnostic markers for colon cancer. These markers can be used singularly or combined, depending on the diagnostic testing need. There is increased flexibility for testing as a positive correlation is related to increased marker levels, decreased marker levels, or the presence of the molecule, depending on the biomarker. Advantages: Biomolecular markers easily identified from biopsy tissue Advanced, FDA-approved diagnostic equipment can be used to measure microRNAs Increased levels, decreased levels, and presence of biomarkers correlate to disease Stage of cancer correlated to measured levels of biomolecules Markers include microRNAs 133α, 21, and 155, Aftiphilin, Neurotensin 1 Receptor, PTEN, and MYD88 Full Description: Colon cancer is the third most common cancer in both men and women and the second leading cause of death from cancer in North America. Current treatment options include surgery alone or in combination with chemotherapy. Although early intervention by surgery can cure up to 90% of patients, colon cancer is often diagnosed at an advanced stage, with colonoscopy as one of the most sensitive screening tests available. To detect colon cancer early and to supplement current testing methods, new diagnostic tests are needed. Related Materials: Bakirtzi, K, et al.
