- Extracellular matrix (ECM) macromolecules are important for creating the cellular environments required during development and morphogenesis of tissues. Matrix metalloproteinases (MMPs) are a family of Zn-dependent endopeptidases that collectively are capable of cleaving virtually all ECM substrates, and play an important role in some physiological and pathological processes. MMP activity can be inhibited by some natural and artificial inhibitors. A newly found membrane-anchored regulator of MMPs, the reversion-inducing-cysteine-rich protein with kazal motifs (RECK), is downregulated when the cells undergo a process of malignant transformation, and is currently the subject of considerable research activity because of its specific structure and function. In this review, we have chosen to concentrate our efforts on the structure, function, regulation, and future prospect of RECK in order to provide a new target for prevention and treatment of tumours

- Abstract: The inhibitor of differentiation/DNA binding 1 (Id-1), a negative regulator of basic helix-loop-helix transcription factors, plays an important role in the regulation of cell proliferation and differentiation. We examined the Id-1 expression by immunohistochemistry in 9 adenomas, 79 primary colorectal adenocarcinomas matched with 40 adjacent normal mucosa specimens and its relationship with clinicopathological factors. The Id-1 expression was increased in the carcinoma compared to the adjacent normal mucosa either in the unmatched and matched samples or to the adenoma. There was no significant difference in the Id-1 expression between normal mucosa and adenoma. The Id-1 expression of carcinoma was increased from Dukes' stages A to B, to C and to D. The cases with lymph node metastasis had a higher rate of a stronger Id-1 expression than those without lymph node metastasis. In conclusion, Id-1 overexpression plays an important role in colorectal cancer progression.
