Fangchinoline (FCL) is an active component isolated from the traditional medicinal plant Stephania tetrandra S. Moore, and has been reported to possess anti-cancer functions in several types of cancers; however, the effect of FCL on gastric cancer metastasis and its underlying molecular mechanisms remain unknown. The current study aimed to investigate the effect of FCL on the cell migration and...

Matrix metalloproteinases (MMPs) and specific endogenous tissue inhibitors of metalloproteinases (TIMPs) mediate rupture of the fetal membranes in both physiological and pathological conditions. MMPs and TIMPs are subject to regulation by DNA methylation in human malignancies and pre-eclampsia. To determine if membrane type 1 MMP (MT1-MMP), MMP2, and TIMP2 are regulated by DNA methylation in hu...

We characterized the expression profile of angiogenesis-related genes (ARG) and matrix metalloproteinase (MMP) genes in preterm infants, with and without bronchopulmonary dysplasia (BPD). We reanalyzed a gene expression dataset for preterm infants from the Gene Expression Omnibus database using the Gene-Cloud of Biotechnology Information platform. A total of 1,652 genes were differentially (1.2...

The expressions of MMP2, -7, -9, -13 and TIMP1, -2, -3 were examined in biopsies and cell lines of head and neck squamous cell carcinomas (HNSCC) to determine the association between the expression profile and TNM-staging of the primary. The expressions of MMP2, -7, -9, -13 and TIMP1, -2, -3 were analyzed in 30 HNSCC biopsies, 7 HNSCC cell lines and 1 keratinocyte cell line using RT-PCR. Negati...

Previously, we described prostate cancer (PCa) detection (83% sensitivity; 67% specificity) in seminal plasma by CE-MS/MS. Moreover, advanced disease was distinguished from organ-confined tumors with 80% sensitivity and 82% specificity. The discovered biomarkers were naturally occurring fragments of larger seminal proteins, predominantly semenogelin 1 and 2, representing endpoints of the ejacul...

BACKGROUND As a novel molecular markerof non-small cell lung cancer (NSCLC), PRDI-BF1 and RIZ homology domain containing protein 14 (PRDM14) is over-expressed in NSCLC tumor tissues. Extracellular matrix degradation mediated by the balance between matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) is one of the most important mechanism in lung cancer metastasis....

Recent evidence suggests that genetic studies may contribute to a better understanding of individual susceptibility to caries. Matrix metalloproteinases (MMPs) and their tissue inhibitors have been suggested to be involved in the caries process. The purpose of this study was to determine if polymorphisms in MMP2 (rs243865), MMP9 (rs17576), MMP13 (rs2252070), and TIMP2 (rs7501477) were associate...

Liver fibrosis occurring as an outcome of non-alcoholic steatohepatitis (NASH) can precede the development of cirrhosis. We investigated the effects of sorafenib in preventing liver fibrosis in a rodent model of NASH. Adult Sprague-Dawley rats were fed a choline-deficient high-fat diet and exposed to diethylnitrosamine for 6 weeks. The NASH group (n=10) received vehicle and the sorafenib group ...

Characterizing the behavior and robustness of enzymatic networks with numerous variables and unknown parameter values is a major challenge in biology, especially when some enzymes have counter-intuitive properties or switch-like behavior between activation and inhibition. In this paper, we propose new methodological and tool-supported contributions, based on the intuitive formalism of temporal ...
