Stromelysin 3

We have cloned from a mouse placenta cDNA library a mouse homologue of the human stromelysin-3 (ST3) cDNA, which codes for a putative matrix metalloproteinase expressed in breast carcinomas. The ST3 protein is well conserved between humans and mice, and the pattern of ST3 gene expression is similar in both species, and shows expression in the placenta, in the uterus, and during limb bud morphogenesis. We show that the ST3 gene can also be expressed in the normal mouse mammary gland. ST3 gene expression was not detected during mammary growth, neither in virgin nor in pregnant mice, but was specifically observed during postlactating involution of the gland, an apoptotic process associated with intense extracellular matrix remodeling. ST3 transcripts were found in fibroblasts immediately surrounding degenerative ducts, suggesting that ST3 gene expression may be associated with the basement membrane dissolution, which occurs during mammary gland involution. Since the ST3 gene is also specifically expressed in fibroblastic cells surrounding invasive neoplastic cells of breast carcinomas, we suggest that ST3 is implicated in extracellular matrix remodeling processes common to mammary apoptosis and breast cancer progression.

Placode Formation

The formation of non-neurogenic placodes is critical prior to the development of several epithelial derivatives (e.g., feathers, teeth, etc.) and their development frequently involves morphogenetic proteins (or morphogens). Matrix metalloproteinases (MMPs) are important enzymes involved in extracellular matrix remodeling, and recent research has shown that the extracellular matrix (ECM) can modulate morphogen diffusion and cell behaviors. This review summarizes the known roles of MMPs during the development of non-neurogenic structures that involve a placodal stage. Specifically, we discuss feather, hair, tooth, mammary gland and lens development. This review highlights the potential critical role MMPs may play during placode formation in these systems.

The Impact

Desmoplastic tumors correspond to a unique tissue structure characterized by the abnormal deposition of extracellular matrix. Breast tumors are a typical example of this type of lesion, a property that allows its palpation and early detection. Fibrillar type I collagen is a major component of tumor desmoplasia and its accumulation is causally linked to tumor cell survival and metastasis. For many years, the desmoplastic phenomenon was considered to be a reaction and response of the host tissue against tumor cells and, accordingly, designated as “desmoplastic reaction”. This notion has been challenged in the last decades when desmoplastic tissue was detected in breast tissue in the absence of tumor. This finding suggests that desmoplasia is a preexisting condition that stimulates the development of a malignant phenotype. With this perspective, in the present review, we analyze the role of extracellular matrix remodeling in the development of the desmoplastic response. Importantly, during the discussion, we also analyze the impact of obesity and cell metabolism as critical drivers of tissue remodeling during the development of desmoplasia. New knowledge derived from the dynamic remodeling of the extracellular matrix may lead to novel targets of interest for early diagnosis or therapy in the context of breast tumors.
