""This pilot study aimed to assess an original test based on the analysis of exfoliated colonocytes as a new approach to colorectal cancer (CRC) detection. DNA was isolated from exfoliated cells collected from the surface of the rectal mucosa by a standardized minimally invasive procedure in a case-control trial involving 66 patients with CRC diagnosis and 110 healthy volunteers (age 50�C70). PicoGreen staining and quantitative real-time PCR (QRTPCR) were used for DNA quantification. Mean DNA scores in ��g/ml obtained http://www.selleck.cn/products/gsk126.html for the control and cancer groups were 2.1 http://www.selleckchem.com/products/Cyclopamine.html (95% CI 1.7�C2.5) and 9.0 (CI 6.7�C11.2) respectively (p
