Recently, matrix metalloproteinases (MMP), in particular the gelatinases MMP-2 and MMP-9, generally considered as tumor markers for clinical applications. A longitudinal 2-years follow-up survey was performed on dogs with cutaneous tumor. Serum samples were obtained from 22 dogs with different cutaneous tumors and 22 health dogs at the time of surgery and one month, three months and one year af...

Purpose: The purpose of this study was to investigate the expression of MMP-9 and MMP-13 on compression side of tooth movement. Material and Methods: Twenty male Wistar rats were used for this experiment. Maxillary right first molar was moved orthodontically with a constant force of 20 g and on the side of the maxillary left first molar was used as control group. On the 4th, 10th and 17th days ...

We report bioluminescence analysis of matrix metalloproteinase (MMP) activity in biological substances using a surface-bound luciferase probe. Intein-fused luciferase protein enables site-specific biotinylation of luciferase in the presence of N-terminus cysteine-biotin via intein-mediated splicing process, resulting in a strong association with high bioluminescence signal onto a NeutrAvidin-co...

Apart from the neoplastic cells, malignant tumours consist of the extracellular matrix (ECM) and normal cells, in particular tumour-associated macrophages (TAM). To understand the mechanisms by which TAM can influence tumour cell invasion we co-cultured the human breast cancer cell lines MCF-7, SK-BR-3 and the benign mammary epithelial cell line hTERT-HME1 with macrophages. Co-incubation enhanc...

Mesothelin (MSLN) and cancer antigen125/mucin 16 (CA125/MUC16) are potential biomarkers for pancreatic cancer (PC) that are co-overexpressed at the invading edges of PC tissues, and their expression correlates with poor survival rates. However, the role of MSLN-MUC16 molecular interaction in PC cell motility and invasion has yet to be elucidated. Using sophisticated bioengineering and molecular...

In the present work, we have synthesized thiazole-hydrazone conjugates 5(a–h) and characterized them using various analytical techniques such as UV, IR, NMR, mass spectrometry. Solvatochromic properties were evaluated in ten solvents with different polarity quantum chemical parameters a DFT study. The antibacterial activity results revealed that compounds 5c, 5d 5g exhibited good efficacy remai...

Matrix metalloproteinases (MMPs) are central to tissue remodelling; however, little is known about the temporal pattern and differential regulation of hepatic MMP expression in the course of chronic human liver disease. Using quantitative reverse transcription-PCR ELISA assays, we studied hepatic mRNA expression of MMP-1, -2, -3, -7, -9, -10, -11, -13 and -14 in patients with chronic hepatitis ...

Although enhanced cardiac matrix metalloproteinase (MMP)-2 synthesis has been associated with ventricular remodeling and failure, whether MMP-2 expression is a direct mediator of this process is unknown. We generated transgenic mice expressing active MMP-2 driven by the alpha-myosin heavy chain promoter. At 4 mo MMP-2 transgenic hearts demonstrated expression of the MMP-2 transgene, myocyte hyp...
