Matrix metalloproteinase enzymes have been implicated in degenerative processes like tumor cell invasion, metastasis, and arthritis. Specific metalloproteinase inhibitors have been used to block tumor cell proliferation. We have examined the interaction of batimastat (BB-94) with a metalloproteinase [atrolysin C (Ht-d), EC 3.4.24.42] active site at 2.0-angstroms resolution (R = 16.8%). The titl...

The matrix metalloproteinases represent an attractive target for cancer treatment, and a number of matrix metalloproteinase inhibitors are undergoing clinical trials. The results of these studies will establish whether any of these compounds are therapeutically useful. Independent of the conclusions from the first generation of studies, the field of matrix metalloproteinase inhibitors remains a...

Bovine trabecular cells in growth phase were exposed to cyclic mechanical stretching of the bottom of a culture dish at a cycle of 30 seconds for 72 hours. The stretched cells produced significantly larger amounts of metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-1 (TIMP-1) after 72 hours, compared with cells in nonstretched control. In contrast, TIMP-2 and MMP-9 levels w...

Research question Maternal alcohol consumption produces fetal retardation and malformations, probably associated with placental defects. Does perigestational up to organogenesis lead abnormal placentation embryo growth restriction by disrupting the vascular endothelial factor (VEGF) system in embryo–placental development? Design Female mice were treated 10% ethanol drinking water before day 10 ...

Advanced age is an independent risk factor for cardiovascular diseases, which might be further exacerbated by estrogen deficiency. Hormone replacement therapy (HRT) decreases risks and events in postmenopausal women; however, its effects are not fully elucidated older individuals. Thus, the aim of our study to examine impact HRT on oxidant/antioxidant homeostasis cardiac remodeling. In experime...

background: current treatments for joint diseases are moderately successful, but unfortunately are associated with significant side effects. this study was undertaken to investigate the combination effects of il-4 and prednisolone on tissue characteristics and production of matrix metalloproteinase-1(mmp-1) in il-lα-treated bovine nasal cartilage (bnc) explants. methods: bnc explants were cultu...

objective(s):n-myc downstream regulated gene 2 (ndrg2) is a candidate gene for tumor suppression. the expression of ndrg2 is down-regulated in several tumors including lung cancer. the aim of this study was to explore the effect of ndrg2 overexpression on invasion, migration, and enzymatic activity of matrix metalloproteinase-2 (mmp-2) and -9 (mmp-9) in human lung adenocarcinoma a549 cells.  ma...

background: the role of matrix metalloproteinase 9 (mmp9) in tumor invasion and progression is prominent. a single nucleotide polymorphism (snp) in the promoter region of mmp9 (-1562 c/t) increases the transcription and expression of this gene. on the other hand, mhc class i chain-related protein a and b (mica/b) in soluble forms may impair tumor immunogenicity by reducing natural killer group ...
