BACKGROUND Matrix metalloproteinases (MMPs) are crucial in the inflammatory and remodeling phases of wound healing. We previously reported the correlation between pro-inflammatory cytokines and timing of successful combat-wound closure. We now extend our studies to investigate the correlation between wound-remodeling MMP expression and wound healing. METHODS Thirty-eight wounds in 25 patients...
هدف از این مطالعه بررسی اشک چشم افرادی است که در طی جنگ ایران و عراق با گاز خردل مواجه شده اند و دارای ضایعات چشمی با نشانه هایی از خشکی چشم مزمن هستند و با افراد سالم برای یافتن میزان فعالیت آنزیم های mmp-2 و mmp-9 مقایسه شده اند. روش کار: در این مطالعه 21 فرد از بین جانبازان شیمیایی که با گاز خردل مواجه شده اند و دارای خشکی چشم و ضایعات چشمی همچون بلفاریت هستند به عنوان گروه بیمار با 18 فرد...
In gastrointestinal epithelium, metaplastic conversion between predominant cell types is associated with an increased risk of neoplasia. However, the mechanisms regulating metaplastic transitions in adult epithelia are largely undefined. Here we show that matrix metalloproteinase-7 (MMP-7) is expressed not only in the majority of human pancreatic ductal adenocarcinoma specimens, but also in hum...
BMS-275291 is an p.o. bioavailable, sulfhydryl-based matrix metalloproteinase (MMP) inhibitor currently in clinical development for the treatment of cancer. This inhibitor was designed to potently inhibit MMP activities while minimally affecting those of other metalloproteases (e.g., sheddases) involved in the release of cell-associated molecules such as tumor necrosis factor-alpha, tumor necro...
Insulin-like growth factor-I (IGF-I) is thought to have antiapoptotic and mitogenic properties in colorectal cancer, whereas IGF-binding protein-3 (IGFBP-3) seems to exert a pro-apoptotic effect. Additionally, matrix metalloproteinase-7 (MMP-7), an enzyme with in vitro ability to degrade IGFBP-3, has been shown to be a prognostic factor in advanced colorectal cancer (ACRC). We studied whether c...
The syndecan family of heparan sulfate proteoglycans contribute to cell adhesion and communication by serving as co-receptors for cell signaling and extracellular matrix molecules. Syndecan-2 is located at the cell surface, and we previously reported that it induces matrix metalloproteinase-7 (MMP-7) expression in colon cancer cells. However, the underlying regulatory mechanisms are unknown. He...
Our previous papers demonstrated that preeclampsia – associated accumulation of collagen and proteoglycans in the umbilical cord tissues is a result of increased biosynthesis and decreased degradation of these components. Metalloproteinases are enzymes engaged in degradation of collagen and protein cores of proteoglycans, including those which bind peptide growth factors. Western Immunoblot met...
The corpus luteum (CL) offers the opportunity to study high proliferative processes during its development and degradation processes during its regression. We examined the mRNA expression of matrix metalloproteases (MMP)-1, MMP-2, MMP-9, MMP-14, MMP-19, tissue inhibitor of MMP (TIMP)-1, TIMP-2, tissue plasminogen activator (tPA), urokinase plasminogen activator (uPA), uPA-receptor (uPAR), PA-in...
The relationship between the expression levels of matrix metalloproteinase-2 (MMP-2) and MMP-9 and breast cancer prognosis was studied. Two breast cancer cell lines (MDA-MB-231 and MCF-7) and one human normal breast cell line (HS578Bst) were investigated. Fluorescence real-time reverse transcription-polymerase chain reaction (RT-PCR) and western blotting were used to detect cellular mRNA and pr...
