Chromosome 18q allelic loss has been reported to have prognostic significance in stage II colorectal carcinoma. We have developed a fluorescent multiplex polymerase chain reaction assay to analyze five microsatellite markers (D18S55, D18S58, D18S61, D18S64 and D18S69) for allelic loss determination at the long […]

High-frequency microsatellite instability has been reported to be associated with good prognosis in colorectal adenocarcinoma. However, methods to assess microsatellite instability (MIN) are based on genetic assays, and are not ideally suited to […]

BRAF mutations in colorectal cancer are linked to loss of hMLH1 expression and proximal location, while independent of K-RAS activation

The RAF gene family encodes RAS-regulated kinases that mediate cellular responses to growth signals. Mutations within the BRAF gene occur in about 10% of colorectal cancers, and are significantly associated to defective mismatch repair (MMR) due […]
