Localized mRNAs are thought to be transported in defined particles to their final destination. These particles represent large protein complexes that may be involved in recognizing, transporting, and anchoring localized messages. Few components of these ribonucleoparticles, however, have been identified yet. We chose the strategy to biochemically enrich native RNA-protein complexes involved in ...

The dose dependent effects of chronic exposure to toluene on the neuronal marker proteins (gamma-enolase, calbindin-D28k) and glial cell marker proteins (alpha-enolase, creatine kinase-B, and beta-S100 protein) were investigated in the central nervous system (CNS) of rats. Three groups of animals were exposed to 100 ppm, 300 ppm, or 1000 ppm toluene vapour eight hours a day, six days a week for...

In order to elucidate the role of S100 protein in vivo we used postembedding electron microscopical immunocytochemistry with commercially available antibodies to S100, and secondary antibodies conjugated to colloidal gold to determine the distribution of S100 protein in the sciatic nerve and the cervical sympathetic trunk of the rat. We found that S100 immunoreactivity in Schwann cells was diff...

The dynamic alterations in the cytoskeletal components actin and intermediate, etc. filaments are required for cell invasion migration. cytoskeleton is a highly structure that governed by delicate balance of filament formation disassembly. To controlling activities key epithelial mesenchymal transition (EMT) could be viable solution to metastasis. Bioinformatics technologies also allow research...

PURPOSE The pathogenesis of pterygia is still not well understood. Recent studies suggest that it may be associated with inflammation and progressive proliferation triggered by ultraviolet radiation. In this study the authors determined that the inflammatory nature of pterygium is reflected in the protein components of tears. METHODS Consent for this study was obtained from 12 patients (avera...

MRP8 and MRP14 are two S100-like calcium-binding proteins of unknown function, associated with numbers of human inflammatory disorders. Both molecules have been described as L1 complex, cystic fibrosis antigen, or p8 and p14. We report here the cloning of mouse MRP8 and MRP14 and their pattern of expression during hematopoiesis. Mouse MRP8 and MRP14 proteins share 59% identity with their human ...

BACKGROUND Studies show S100 as a possible acute ischemic stroke (AIS) marker. OBJECTIVES Determine (1) whether S100 serum concentrations correlate with stroke symptom onset, infarction volume, stroke severity, functional outcome, or length of hospital stay; (2) whether S100 serial measurements are useful markers for ongoing brain ischemia, and (3) whether S100 levels at various time interval...

In our study, we decided to compare S100 protein expression in the material obtained from the epididymes of 5- and 12-month-old calves, and adult European bison, and to detect any differences in S100 expression according to the animal age and size of the organ examined. We used the epididymes obtained from 6 adult European bison aged 6-12 years, from 6 at the age of 12 months and 6 calves aged ...
