The study has revealed the presence of fibronectin (FN) fragments and a lack of intact FN in 72 seminal plasma samples. The FN fragmentation was examined by immunoblotting with a monoclonal antibody specific to the central cellular FN domain and was confirmed with a monoclonal antibody directed to the C-terminal domain of FN. Nine FN fragments between 60(More)
OBJECTIVE To determine whether the expression of some fibronectin (FN) domains and a degree of FN degradation are associated with the progression of rheumatoid arthritis (RA). METHODS Based on the radiographs of the hands of RA patients, three groups of synovial fluid and plasma samples were distinguished: (i) those with early radiological changes, (ii)(More)
N-Acetyltransferase (NAT), a rate-limiting enzyme in the melatonin synthesis which converts serotonin to N-acetylserotonin, shows a distinct circadian rhythm in the rat pineal gland and retina, with low activities during the light phase and peak activities during the dark phase. Hydroxyindole-O-methyltransferase (HIOMT), an enzyme which methylates(More)
The expressions of terminal sugars in synovial and plasma fibronectins were studied in relation to rheumatoid arthritis (RA) progression defined according to the early, established and late radiological changes in the patients’ hands. The relative amounts of sialic acid and fucose were analyzed by lectin-ELISA using appropriate sialic acid-linked α2-3(More)
In the present study the expression of alternatively spliced synovial EDA-containing FN (EDA-FN) was analyzed in plasma and synovial fluid samples of rheumatoid arthritis (RA) patients with from 2 months to 20 years disease duration. The patient samples were divided into groups: those with early, established, and late progressive radiographic changes as(More)
The aim of the work was to analyse fibronectin (FN) domain immunoreactivities and profiles of FN fragmentation in seminal plasmas of fertile normozoospermic and infertile leucocytospermic male patients. ELISA with domain-specific monoclonal antibodies and immunoblotting were used in these measurements. Immunoblotting of normal and leucocytospermic seminal(More)
To find whether the plasma fibronectin (FN) molecular status can be useful to differentiate between rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). The expression of plasma FN domains was determined by ELISA using monoclonal domain-specific antibodies. FN molecular forms were revealed by immunoblotting and analyzed by densitometry. The(More)
Fibronectin is an extracellular matrix component which appears in different isoforms, due to alternative mRNA splicing of the ED-A, ED-B and III-CS regions and subsequent post-translational modification. It is composed of multiple homologous repeats and contains many functional domains. Because of its ability to interact with many ligands including cells,(More)
