Melanotransferrin is a glycoprotein expressed at the cell membrane and secreted in the extracellular environment. Recombinant truncated form of membrane-bound melanotransferrin (sMTf) was reported to exert in vitro anti-angiogenic properties. Here we show that sMTf treatment leads to a 50% inhibition of neovascularization in Matrigel implants when stimulated by growth factors. Using a glioblast...

BACKGROUND Rut-C30 is a cellulase-hyperproducing Trichoderma reesei strain and, consequently, became the ancestor of most industry strains used in the production of plant cell wall-degrading enzymes, in particular cellulases. Due to three rounds of undirected mutagenesis its genetic background differs from the wild-type QM6a in many ways, of which two are the lack of a 83 kb large sequence in s...

Rat hepatic microsomal squalene synthetase (EC 2.5.1.21) was induced 25-fold by feeding rats with diet containing the hydroxymethylglutaryl-coenzyme A reductase inhibitor, fluvastatin, and cholestyramine, a bile acid sequestrant. A soluble squalene synthetase protein with an estimated mass of 32-35 kDa, as determined by gel filtration chromatography on Sephacryl S-200 column, was solubilized ou...

2-5A-dependent RNase is the terminal factor in the interferon-regulated 2-5A system thought to function in both the molecular mechanism of interferon action and in the general control of RNA stability. However, direct evidence for specific functions of 2-5A-dependent RNase has been generally lacking. Therefore, we developed a strategy to block the 2-5A system using a truncated form of 2-5A-depe...

The most area consuming arithmetic operations in high-performance circuit’s Finite Impulse Response (FIR) multiplication is one. We are using different types of multipliers to reducing the cost of effective parameters in FIR filter design. We use only truncated multipliers in design, by using these multipliers we consume some more area and power, and ineffective results in transposed form. The ...

Hepatocyte growth factor (scatter factor) is an angiogenic growth factor that binds to its cellular transmembrane receptor, c-met. Both HGF and c-met are expressed by vascular smooth muscle and endothelial cells, where HGF may exert autocrine and paracrine effects. We have found that human aortic smooth muscle cells (HASMCs) and human umbilical vein endothelial cells (HUVECs) release a soluble,...

Motivations Lipases, mainly of microbial origin, represent the most widely used class of enzymes in biotechnological applications and organic chemistry. Bacterial lipases are members of the structural superfamily of / hydrolases that catalyze the hydrolysis and synthesis of a variety of acylglycerols at the lipid-water interface. Optimization of features and catalytic activity of lipases as the...

BACKGROUND Kawasaki disease (KD) is an acute vasculitis in children that can cause coronary artery abnormalities. Its diagnosis is challenging, and many cytokines, chemokines, acute phase reactants, and growth factors have failed evaluation as specific biomarkers to distinguish KD from other febrile illnesses. We performed protein profiling, comparing plasma from children with KD with febrile c...

Catechol 2,3-dioxygenases (C23Os, E.C.1.13.12.2) are two domain enzymes that catalyze degradation of monoaromatic hydrocarbons. The catalytically active C-domain of all known C23Os comprises ferrous ion ligands as well as residues forming active site pocket. The aim of this work was to examine and discuss the effect of nonsense mutation at position 289 on the activity of catechol 2,3-dioxygenas...

‘I’hc truncated singular value decomposition (SW) is considered as a method for rcgularization of ill-posed linear lcast squares pro&ins. In particular, the .truncatcd SVl> solution is compared wi th the usua l rcguiarizcd so.lution. Ncccssary conditions arc d&cd in which the two m&hods will yield similar results.
