Aims The impact of MMP-1 (-519A/G, -1607 1G/2G), MMP-3 Lys45Glu (A/G), MMP-7 -181A/G, and MMP-12 -82A/G variants and plasma MMP levels on obesity and microvascular reactivity in Tunisians. Methods Our population included 202 nonobese and 168 obese subjects. Anthropometric, biochemical, and microvascular parameters were determined according to standard protocols. PCR-RFLP and ELISA were used t...
PURPOSE The proteolytic activity of matrix metalloproteinases (MMPs) is involved in pathologic angiogenesis in the eye. However, it is unknown whether MMPs may stimulate the production of the major angiogenic factor, vascular endothelial growth factor (VEGF). The authors investigated whether MMP-2 and MMP-9 alter the expression of VEGF by retinal pigment epithelial (RPE) cells. They also sought...
Matrix-metalloproteases (MMPs) and their tissue-inhibitors (TIMPs), modulated by different single nucleotide polymorphisms (SNPs), are critical in sepsis development. Ninety ICU severely septic and 91 ICU uninfected patients were prospectively studied. MMP-1 (-1607 1G/2G), MMP-3 (-1612 5A/6A), MMP-8 (-799 C/T), MMP-9 (-1562 C/T), and MMP-13 (-77A/G) SNPs were genotyped. Plasma MMPs (-1, -2, -3,...
Thymomas are the common neoplasms of mediastinum, and type AB is most frequent case. All thymomasare potential for invasion to adjacent tissues considered malignant. Capsular one itsprognostic indicators. Matrix metalloproteinase-2 (MMP-2) a family proteinases that has abilityto degrade component extracellular matrix affect tumor or metastasis. Cytoplasmicexpression p21 protein can be significa...
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...
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...
Matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9) and membrane-type matrix metalloproteinase 1 (MT1-MMP) are involved in colorectal cancer invasion and metastasis. Reversion-inducing cysteine-rich protein with Kazal motifs (RECK) inhibits MMP-2, MMP-9 and MT1-MMP. We examined the clinicopathological significance of the relative expression of these genes in patients with col...
PURPOSE Matrix metalloproteinases (MMP) are proteolytic enzymes that play an important role in various aspects of cancer progression. In the present work, we have studied the prognostic significance of serum levels of gelatinase B (MMP-9), collagenase-1 (MMP-1), and collagenase-3 (MMP-13) in patients with advanced melanoma. EXPERIMENTAL DESIGN Total pretreatment serum levels of MMP-9 in 71 pa...
هدف: کبد چرب غیر الکلی طیفی از حالات بالینی – آسیب شناختی است که با رسوب قطرات چربی در کبد بیمارانی که سابقه مصرف الکل ندارند ، مشخص می شود . هیپرمتیلاسیون dna در نواحی پروموتر ژن ها نقش مهمی در کاهش بیان ژن های دخیل در بیماری کبد چرب غیر الکلی دارد . هدف از این مطالعه بررسی متیلاسیون پروموتر ژن های gstt1 ، gstp1 ، apoe ، cpt-1a ، mmp-9 و ctla-4 در بیماران مبتلا به کبد چرب غیر الکلی در جنوب شرق...
PURPOSE Matrix metalloproteinases (MMP) are proteolytic enzymes implicated in cancer progression and metastasis. We sought to determine the role of epithelial (tumor cell-derived) and stromal (host-derived) expression of MMPs in predicting the clinical outcome of patients with epithelial ovarian cancer (EOC). EXPERIMENTAL DESIGN MMP-2, MMP-9, and membrane type 1 (MT1)-MMP expression was evalu...
