Biglycan, a small leucine-rich proteoglycan, is a ubiquitous ECM component; however, its biological role has not been elucidated in detail. Here we show that biglycan acts in macrophages as an endogenous ligand of TLR4 and TLR2, which mediate innate immunity, leading to rapid activation of p38, ERK, and NF-kappaB and thereby stimulating the expression of(More)
There is growing evidence that the two small leucine-rich proteoglycans biglycan and decorin regulate the assembly of connective tissues and alter cell behavior during development and pathological processes. In this study, we have used an experimental animal model of unilateral ureteral ligation and mice deficient in either biglycan or decorin. We(More)
During glomerular inflammation mesangial cells are the major source and target of nitric oxide that pro-foundly influences proliferation, adhesion, and death of mesangial cells. The effect of nitric oxide on the mRNA expression pattern of cultured rat mesangial cells was therefore investigated by RNA-arbitrarily-primed polymerase chain reaction. Employing(More)
Oats as a source of antioxidants and complex polysaccharides are currently an important component in human nutrition. Producing healthy, safe and high-quality grain for this purpose depends upon growing oat cultivars with improved resistance to diseases caused by Fusarium spp. producing mycotoxins. Thirteen cultivars of naked (Ábel, Detvan, Izák and(More)
Nephrin is an important constituent of the glomerular filtration barrier and alteration of its expression is associated with severe proteinuria. In this study we show that injection of an anti-Thy1.1 antibody in rats not only induces a mesangioproliferative glomerulonephritis associated with increased proteinuria, but also leads to a sustained increase of(More)
PDGF and nitric oxide (NO) have been shown to participate in the progression of several forms of glomerulonephritis. A potential influence of NO on PDGF-mediated signaling cascades was therefore examined. Treatment of rat mesangial cells (MC) with the NO donors diethylenetriamine NO (DETA-NO) or spermine-NONOate resulted in a time- and dose-dependent(More)
We present a software tool for high-level design and analysis of large-scale embedded real-time software, which has been integrated into a vehicle control platform development tool chain. The integration framework of the tool chain is based on CORBA services, and the data exchanges among different tools are carried out through an analysis interchange format(More)
The artificial gene D6D encoding the enzyme ∆⁶desaturase was designed and synthesized using the sequence of the same gene from the fungus Thamnidium elegans. The original start codon was replaced by the signal sequence derived from the wheat gene for high-molecular-weight glutenin subunit and the codon usage was completely changed for optimal expression in(More)
Membrane-bound desaturases play key role in metabolism of polyunsaturated fatty acids. Characterization of these enzymes and their genes is the first step in basic understanding of their proper functioning in living cells as well as in tailor-made preparation of highly-specific and highly-productive strains of microorganisms interesting for applied(More)
Polyunsaturated fatty acids (PUFAs) affect diverse physiological processes and human health. Most cereals are poor in n-3 and n-6 PUFAs. Using biolistics, barley (Hordeum vulgare L. cv. Golden Promise) was transformed with an artificial gene encoding Δ6-desaturase (D6D) under an endosperm-specific promoter. This artificial gene was designed from the(More)
