Description
The purpose of this study was to characterize the transcriptional effects induced by intramuscular IFN-beta-1a treatment (Avonex, 30 g once weekly) in patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of peripheral blood mononuclear cells from 24 MS patients within the first four weeks of IFN-beta administration.

Description
The purpose of this study was to analyze the transcriptional effects induced by glatiramer acetate treatment (GA; Copaxone, 20 mg injected subcutaneously once daily) in blood monocytes of patients with relapsing-remitting form of multiple sclerosis (MS). By using Affymetrix DNA microarrays, we obtained genome-wide expression profiles of monocytes from 8 MS patients within the first two months of GA administration.

Description
This study was performed to identify gene expression differences in not otherwise specified soft tissue sarcomas (NOS, malignant fibrous histiocytomas) and correlate them to histological findings and the clinical course. RNA was isolated and differential gene expression was analysed by the microarray technique.

Description
We assessed the apoptotic and antiproliferative effects of resveratrol, pycnogenol and its metabolites on HT1080 human fibrosarcoma cells in vitro. Viability, apoptosis and necrosis were quantified by FACS analysis (Propidiumiodide/AnnexinV staining). Gene expression was analysed by RNA-Microarray. Cell proliferation was analysed by BrdU ELISA assay.
Publication Title
Resveratrol induces apoptosis and alters gene expression in human fibrosarcoma cells.

Description
Through Next Generation Sequencing (mRNA-Seq) of intracellular miRNAs in measles virus-stimulated B and CD4+ T cells isolated from high and low antibody responders to measles vaccination, we identified a set of B cell-specific miRNAs (e.g., miR-151a-5p, miR-223, miR-29, miR-15a-5p, miR-199a-3p, miR-103a, and miR-15a/16 cluster) associated with measles-specific antibody response after vaccination. No CD4+ T cell-specific miRNA expression differences between high and low antibody responders were found. DIANA tool was used for gene/target prediction and pathway enrichment analysis and this yielded several biological processes/pathways, including regulation of adherens junction proteins, Fc-receptor signaling pathway, phosphatidylinositol-mediated signaling pathway, growth factor signaling pathway/pathways, transcriptional regulation, apoptosis and virus-related processes, that were significantly associated with neutralizing antibody titers after measles vaccination. This study demonstrates that miRNA expression directly or indirectly influences humoral immunity to measles vaccination and suggests that B cell-specific miRNAs may potentially serve as predictive biomarkers of vaccine response. Overall design: Examination of miRNA expression differences in/between purified B and CD4+ T cells of high and low responders to measles vaccination.
Publication Title
Differential miRNA expression in B cells is associated with inter-individual differences in humoral immune response to measles vaccination.

Description
RNase Y of Bacillus subtilis is a key member of the degradosome and important for bulk mRNA turnover. In contrast to B. subtilis, the RNase Y homologue (rny/cvfA) of Staphylococcus aureus is not essential for growth. Here we found that RNase Y plays a major role in virulence gene regulation. Accordingly, rny deletion mutants demonstrated impaired virulence in a murine bacteraemia model. RNase Y is important for the processing and stabilisation of the immature transcript of the global virulence regulator system SaePQRS. Moreover, RNase Y is involved in the activation of virulence gene expression at the promoter level. This control is independent of both the virulence regulator agr and the saePQRS processing and may be mediated by small RNAs some of which were shown to be degraded by RNase Y. Besides this regulatory effect, mRNA levels of several operons were significantly increased in the rny mutant and the half-life of one of these operons was shown to be extremely extended. However, the half-life of many mRNA species was not significantly altered. Thus, RNase Y in S. aureus influences mRNA expression in a tightly controlled regulatory manner and is essential for coordinated activation of virulence genes.
