Colorectal cancer (CRC) is a leading cause of cancer related death in the western countries. It remains an important health problem, often under-diagnosed. The symptoms can appear very late and about 25% of the patients are diagnosed at metastatic stage. Familial adenomatous polyposis (FAP) is an inherited colorectal cancer syndrome, characterized by the early onset of hundred to thousands of adenomatous polyps in the colon and rectum. Left untreated, there is a nearly 100% cumulative risk of progression to CRC by the age of 35-40 years, as well as an increased risk of various other malignancies. CRC can be prevented by the identification of the high risk population and by the timely implementation of rigid screening programs which will lead to special medico-surgical interventions. [less ▲]

Desmoid tumours are locally invasive soft tissue tumours in which beta-catenin mediated TCF-dependent transcription is activated. The role of soluble factors secreted by the myofibroblastic desmoid tumour, which could stimulate tumour invasiveness, was investigated. Using collagen gel invasion assays, the presence of factors stimulating invasion in desmoid conditioned media (CM) could be established. Since matrix metalloproteinases (MMPs) have been implicated in the process of tumoral invasion, the expression levels of the MMP family members were evaluated. Quantitative reverse transcription-PCR was used to determine the expression levels of MMP1, MMP2, MMP3, MMP7, MMP11, MMP12, MMP13, MMP14 and the inhibitors TIMP1, TIMP2 and TIMP3. Besides overexpression of MMP7, a known TCF-dependent target gene, a striking upregulation of the expression levels of MMP1, MMP3, MMP11, MMP12 and MMP13 in desmoid tumours, compared to unaffected fibroblasts from the same patients, was found. Treating the CM of desmoids with a synthetic and a physiologic MMP inhibitor reduced the invasion-stimulating capacity of the desmoid CM by approximately 50%. These results suggest the involvement of soluble factors, released by the desmoid cells, in stimulating invasion and implicate the MMPs as facilitators of invasion. [less ▲]
