Although smad4 is regarded as a signaling mediator of the tgfβ signaling pathway, its role as a major suppressor of colorectal cancer progression and the molecular events underlying this phenomenon, remain elusive. Loss of chromosome 18q21 is well documented in colorectal cancer, and it has been suggested that this loss targets the dcc , dpc4 / smad4 , and smad2 genes. Colorectal cancer patients with tumours expressing high smad4 levels have significantly better survival than patients with low level (alazzouzi et al, 2005; In addition to colon cancer, poor prognosis has been associated with mutations, deletions and low levels of smad4 in gliomas and pancreatic, prostate and lung cancers. The vast majority are adenocarcinomas. Using 99 clinical specimens and human colorectal cancer cell lines, we investigate the relationship between smad4 expression and neutrophil accumulation. The tgfβ family of cytokines regulates critical processes during the lifecycle of metazoans, with. Smad4 frequently is lost from colorectal cancers (crcs), which is associated with the development of metastases and a poor prognosis. In mice, colon tumors that express ccl9 recruit ccr1þ myeloid cells, which facilitate tumor invasion and metastasis by secreting matrix metalloproteinase 9.
