The human SFRS9/SRp30c belongs to the SR family of splicing regulators. Despite evidence that members of this protein family may be targeted by arginine methylation, this has yet to be experimentally addressed. In this study, we found that SFRS9 is a target for PRMT1-mediated arginine methylation in vitro, and that it is immunoprecipitated from HEK-293 lysates by antibodies that recognize both mono- and dimethylated arginines. We further observed that upon treatment with the methylation inhibitor Adox, the fluorescent EGFP-SFRS9 re-localizes to dot-like structures in the cell nucleus. In subsequent confocal analyses, we found that EGFP-SFRS9 localizes to nucleoli in Adox-treated cells. Our findings indicate the importance of arginine methylation for the subnuclear localization of SFRS9.

Mucus glycoproteins (mucins), the principal determinants of mucus protective qualities and mucosal defense, are studied extensively to define pathological aberrations in the relation to gastrointestinal disease and to develop the mucous barrier strengthening agents. Recent work from our laboratory provided evidence as to the initial stages of the gastrointestinal mucin synthesis, molecular size of the apomucin, its macromolecular organization and interaction with other elements of gastrointestinal mucus. Using monoclonal antibodies against apomucin (clone 1H7), O- glycosylated with N-acetylgalactosamine apomucin (clone 2B4), and that against carboxyl terminal of the apomucin (clone 3G12), the mucin synthesizing polysomes were isolated and glycosylated peptides ranging in size from 6-60kDa identified. The in vitro synthesis in the cell-free system also afforded 60-64kDa products recognized by 1H7 and 3G12 antimucin MAbs. The obtained results provided evidence that the mucin core consists of 60kDa peptide which at cotranslational stage is O-glycosylated with N-acetylgalactosamine. Studies on mucin polymer assembly revealed that mucin preparations prepared by equilibrium density gradient centrifugation and Sepharose 2B chromatography (Mantle, M., Mantle, D., and Allen, A. (1981) Biochem. J. 195, 277-285) are not completely purified and contain DNA and extraneous proteins. The evidence was obtained that so called mucin “link protein”, 118kDa glycopeptide, is a N-glycosylated fragment of fibronectin, whereas the supposedly native undegraded mucin isolated by Carlstedt et al. (Biochem. J. (1983) 211, 13-22) was found to contain mucin-fibronectin-DNA complexes. The general picture that emerged from the studies is that the pure mucin consists of 60kDa glycosylated peptides only. The carboxyl terminal (8-12kDa fragment) of these peptides is not glycosylated (naked) and is responsible for mucin interaction with fibronectin and other fibronectin-like extracellular matrix proteins. While the formation of the mucosal coat depends on many other factors and extracellular components, our findings on mucin structure and interaction with the extracellular matrix proteins provide explanation as to the possible mechanism of mucin adherence to the epithelial surfaces.

The immunoreactivity of haemagglutinin (HA) polypeptides of equine influenza virus was compared among the strains isolated in Poland, using H3 monoclonal antibody. A stronger signal in immunoblot reaction was observed for A/equi/Pulawy/2008 HA polypeptides compared to A/equi/Pulawy/2006, despite the fact that both strains are phylogenetically closely related and belong to Florida clade 2 of American lineage. The strongest signal, observed in the case of A/equi/Pulawy/2008, seemed to be connected with the presence of G135, 1213, E379, and/or V530 instead of R135, M213, G379, and 1530 present in A/equi/Pulawy/2006 HA sequence. This implies that point mutations within amino acid sequences of HA polypeptides of equine influenza virus may change their immunoreactivity even when they are not located within five basic antigenic sites.

Blood and lymphatic vessel formation is an indispensable factor for cancer progression and metastasis. Therefore, various strategies designed to block angiogenesis and lymphangiogenesis are being investigated in the hope to arrest and reverse tumor development. Monoclonal antibodies, owing to their unequalled diversity and specificity, might be applied to selectively inhibit the pathways that cancer cells utilize to build up a network of blood vessels and lymphatics. Among the possible targets of antibody-based therapies are proangiogenic and prolymphangiogenic growth factors from the VEGF family and the receptors to which they bind (VEGFRs). Here, we present molecular mechanisms of angiogenesis and lymphangiogenesis exploited by tumors to progress and metastasise, with examples of antibody-based therapeutic agents directed at interfering with these processes. The expanding knowledge of vascular biology helps to explain some of the problems encountered in such therapies, that arise due to the redundancy in signaling networks controlling the formation of blood and lymphatic vessels, and lead to tumor drug resistance. Nonetheless, combined treatments and treatments focused on newly discovered proangiogenic and prolymphangiogenic factors give hope that more prominent therapeutic effects might be achieved in the future.

Prompt and accurate diagnosis is necessary to start adequate treatment for different affecting species including P. falciparum and P. vivax. Here we described the Wondfo Rapid diagnostic Kit (Pf-HRP2/PAN-pLDH) for the detection of P. falciparum and pan-plasmodium in patient specimen by using a nano-gold immunochromatographic assay. Our rapid assay adapted nano-gold labeling techniques and the monoclonal antibodies (mAbs) against both histidine rich protein-2 (Pf HRP-2) of P. falciparum and pan plasmodium-specific pLDH (pan pLDH). The established two-antibody sandwich immunochromatographic assay could detect P. falciparum and pan-plasmodium. The sensitivity and specificity of Wondfo rapid diagnostic kit were determined by comparing with the “gold standard” of microscopic examination of blood smears. In this study1023 blood samples were collected from outpatient clinics in China and Burma, and detected by both Wondfo kit and microscopic examination. The detection sensitivity and specificity of Wondfo rapid diagnostic kit were 96.46% and 99.67% for P. falciparum (HRP2), 95.03% and 99.24% for pLDH, 96.83% and 99.74% for non-falciparum species, 96.70% and 99.74% for P. vivax, respectively. These results indicate that Wondfo rapid diagnostic assay may be useful for detecting P. falciparum and non-P. falciparum (especially P.v.) in patient specimen.
