The expression of oncofetal H19 RNA and its localization/cellular source was analyzed in synovial tissue (ST) and isolated synovial macrophages (Mphi) or synovial fibroblasts (SFBs) by reverse transcriptase-polymerase chain reaction (RT-PCR), in situ hybridization, and immunohistochemistry. RT-PCR showed significantly higher H19 expression in ST from(More)
A very basic secreted protein which displays antifungal activity was isolated from the medium of the mold Aspergillus giganteus. The protein consists of 51 amino acid residues whose sequence was determined as Ala-Thr-Tyr-Asn-Gly-Lys-Cys-Tyr-Lys-Lys-Asp-Asn- Ile-Cys-Lys-Tyr-Lys-Ala-Gln-Ser-Gly-Lys-Thr-Ala-Ile-Cys-Lys-Cys-Tyr-Val- Lys-(More)
A C-terminal truncated form of membrane-type 4 matrix metalloproteinase (MT4-MMP; MMP 17), lacking the hemopexin-like and transmembrane domain, was expressed in Escherichia coli. The catalytic domain was produced by tryptic activation of the recombinant proenzyme and proved to be catalytically active towards the fluorogenic substrate for matrix(More)
C-terminal truncated membrane-type 2 matrix metalloproteinase (MT2-MMP1-269), comprising prodomain and catalytic domain, was expressed as a soluble protein in Escherichia coli. Unlike the corresponding form of MT1-MMP, which can be isolated as a 31 kDa protein, MT2-MMP1-269 proved to be comparatively instable, and already the freshly isolated preparation(More)
The gene encoding the precursor of a small secretory protein with antifungal activity was isolated from A. giganteus and characterized by restriction mapping, hybridization and nucleotide sequencing. The promoter contains a typical TATA-box at a distance of 135 bp upstream of the open reading frame. The open reading frame is interrupted by two small introns(More)
The three forms of neutrophil gelatinase B-monomer, homodimer and monomer/lipocalin complex-, were isolated from phorbolester stimulated neutrophil granulocytes by chromatography on gelatin-Sepharose and heparin-Ultrogel. On average, about 50% of the monomer/lipocalin complex was found to be complexed with TIMP-1. After activation with trypsin monomer,(More)
Membrane binding of urokinase type plasminogen activator (u-PA) is thought to play a pivotal role in connective tissue remodeling and invasive processes. We compare the ability of different matrix-metalloproteinases involved in connective tissue turnover to cleave pro-urokinase type plasminogen activator between the catalytic domain and the receptor binding(More)
Prevotella intermedia, a Gram-negative obligate anaerobic black-pigmented oral bacterium, belongs to a small group of microorganisms that is closely associated with the initiation of periodontal diseases. Lipopolysaccharide (LPS), an outer membrane component, is one of the main virulence factors of this bacterium. The aim of this study was to examine the(More)
OBJECTIVE To investigate the efficacy of oral type II collagen in the treatment of early rheumatoid arthritis (RA). METHODS Ninety patients with RA (disease duration < or = 3 years) were treated for 12 weeks with oral bovine type II collagen at 1 mg/day (n = 30) or 10 mg/day (n = 30) or with placebo (n = 30), in a double-blind randomized study.
