| [en] The actin-binding protein gelsolin is involved in cell motility via the regulation of actin cytoskeleton, and its expression is modified in several human cancers. However, the potential implication of this protein in colorectal carcinogenesis is debated. By using immunohistochemistry, we studied gelsolin expression in 69 cases of colon adenocarcinomas and in 72 lesions representative of the different stages of colonic tumorigenesis. In addition, we performed Northern blot analysis of gelsolin messenger RNA in 12 paired samples of human colon cancer and normal corresponding mucosa. Gelsolin protein and messenger RNA expressions were severely down-regulated in all adenocarcinomas tested. Moreover, gelsolin protein was down-regulated in a large proportion of high-grade adenomas (14/16) before the acquisition of invasive properties but in only a small proportion of low grade adenomas and serrated adenomas (2/30) and in none of the 9 cases of nonneoplastic hyperplastic polyps tested. Our results therefore demonstrate that gelsolin down-regulation is an early and almost constant event in colon carcinogenesis and is associated with the transition from adenoma to carcinoma. | |
