Bearing in mind the prevalent occurrence of sulfur deficiency in soils, it is highly essential to comprehend the molecular processes of plant response to the changing conditions of sulfur nutrition. As there is an increasing understanding of ubiquitin-proteasomal protein degradation system participation in nutrient deficiency response, we could predict its input to the sulfur metabolism as well. Therefore, we decided to investigate the consequences of proteasome malfunction in Arabidopsis in sulfur deficient conditions.

Response to a DNA vaccine against the H5N1 virus depending on the chicken line and number of doses.
Specimen part, Treatment
View SamplesLaying hens Rosa 1 were immunized with two doses of DNA vaccine, based on the hemagglutinin (HA) DNA from H5N1 virus, in comparison to the control group, which was administered an empty vector (pCI). Additional groups of Rosa 1 hens were treated with one dose of above described vaccine or empty vector. Gene expression changes in the spleens of chickens were investigated at 7 day post last vaccination dose.

View SamplesBroilers were immunized with three variants of subunit vaccines, based on the hemagglutinin (HA) DNA and Pichia-produced HA protein from H5N1 virus, in comparison to the control group, which was administered an empty vector (pCI). Gene expression changes in the spleens of chickens were investigated at 7 day post booster dose.

View SamplesMyocardial infarction (MI) often results in left ventricular (LV) remodeling followed by heart failure (HF). It is of great clinical importance to understand the molecular mechanisms that trigger transition from compensated LV injury to HF and to identify relevant diagnostic biomarkers. In this study, we performed transcriptional profiling of LVs in rats with a wide range of experimentally induced infarct sizes and of peripheral blood mononuclear cells (PBMCs) in animals that developed HF.

View SamplesStudies in yeast and animals have revealed that histone deacetylases (HDACs) often act as components of multiprotein complexes, including chromatin remodeling complexes (CRCs). In our group, we found evidence for the interaction between Arabidopsis HD2C deacetylase and a BRM-containing SWI/SNF chromatin remodeling complex. Moreover, we revealed a novel function of HD2C as a regulator of the heat stress response. HD2C transcript levels were strongly induced in plants subjected to heat treatment and the expression of selected heat-responsive genes was up-regulated in heat-stressed hd2c mutant, suggesting that HD2C acts to down-regulate heat-activated genes.

View SamplesRepresentatives of two families of bacterial Par proteins, ParA and ParB, are encoded by the majority of bacterial chromosomes in the close vicinity of oriC. ParA(Soj) and ParB(Spo0J) proteins of Pseudomonas aeruginosa are both important for optimal growth, nucleoids segregation, cell division and different types of motility. Comparative transcriptome analysis of parAnull, parBnull mutants versus parental PAO1161 strain of P. aeruginosa demonstrated global changes in genes expression pattern in logarithmic phase of planktonic cultures grown on rich medium. The set of genes that were similarly regulated in both mutant strains as compared to the wild-type strain as well as two sets of genes uniquely affected in the particular mutant were defined suggesting that ParA and ParB may act in common and independently. In general, many genes involved in cell division, DNA and RNA processing and metabolic processes were down-regulated in mutant cells, in contrast genes which products play a role in adaptation, protection, motility, cell-to-cell signaling as well as signal transduction increased their expression in par mutant cells. Besides their role in chromosome segregation, ParA and ParB seem to have the potential to regulate genes transcription. The altered expression of a large number of genes encoding known or predicted transcriptional regulators and genes coding for products involved in c-di-GMP signalling, suggests that the part of observed global changes in genes expression pattern in parAnull and parBnull mutants might be the effect of indirect regulation mediated by regulatory genes under ParA and ParB control. The extended regulatory network provides the mechanism to modulate genes expression in response to the stage of the chromosome segregation process and cell cycle.

View SamplesDespite a substantial progress in diagnosis and therapy, acute myocardial infarction (MI) is a major cause of mortality in the general population. A novel insight into the pathophysiology of myocardial infarction obtained by studying gene expression should help to discover novel biomarkers of MI and to suggest novel strategies of therapy. The aim of our study was to establish gene expression patterns in leukocytes from acute myocardial infarction patients.
