Matrix metalloprotease 2 (MMP-2) and matrix metalloprotease 9 (MMP-9) type IV collagenases in colorectal cancer.
Using quantitative zymography, we measured activity of the type IV collagenases metalloprotease 2 (MMP-2) and MMP-9 in 192 biopsies from colorectal carcinomas, adenomas, and normal bowel. The median level of MMP-9 in samples from Dukes' stage A (n = 18) or C (n = 48) tumors was significantly higher than in stage B carcinomas (n = 65), adenomas (n = 25), and normals (n = 36; P = 0.0001). The med...
متن کاملImmunohistochemical expression of matrix metalloprotease-2 and matrix metalloprotease-9 in the disks of patients with temporomandibular joint dysfunction.
PURPOSE Matrix metalloproteases (MMPs) are tissue-remodeling enzymes that function during the remodeling process, such as in immune-inflammatory diseases. Metalloprotease-2 (MMP-2) and metalloprotease-9 (MMP-9) are gelatinases that degrade several types of extracellular matrix collagen. It is hypothesized that in temporomandibular joint (TMJ) dysfunction, MMP-2 and MMP-9 expression levels may b...
متن کامل4215 Matrix-metalloprotease activation in cultured corneas
Purpose. Vascular endothelial growth factor (VEGF) binds to oorneal endothelial cells (BCE). We screened BCE for the expression of the VEGF receptors KDRIFLK-I and FLT-1 and analysed their functions. Methods. The expression of KDRIFLK-1 and FLT-1 mRNA was analysed by northern-blot. BCE were also transfeoted with expression vectors carriing the VEGF receptors sequences. Their ability to prolifer...
متن کاملEndostatin inhibits human tongue carcinoma cell invasion and intravasation and blocks the activation of matrix metalloprotease-2, -9, and -13.
Endostatin, a 20-kDa collagen XVIII fragment, inhibits angiogenesis and tumor growth in vivo, but the mechanisms are still unclear. Matrix metalloproteases (MMPs), a family of extracellular and membrane-associated endopeptidases, collectively digest almost all extracellular matrix and basement membrane components, and thus play an important role in tumor progression. We studied the effects of r...
متن کاملKey role of the NO-pathway and matrix metalloprotease-9 in high blood flow-induced remodeling of rat resistance arteries.
OBJECTIVE Blood flow is altered in metabolic and ischemic diseases with dramatic consequences. Resistance arteries structure and function remodel in response to chronic blood flow changes through a mechanism remaining mainly unknown. We hypothesized that the NO pathway and matrix metalloproteases (MMPs) activation might play a role in flow (shear stress)-induced microvascular remodeling. METH...
