Human peripheral blood mononuclear cells were cultured in presence of H37Ra strain at 37oC, 5%CO2. Cellular aggregates were collected at 24h, and RNA extracted and hybridized to Affymetrix microarrays (HG-U133). Raw data from microarray experiments was analyzed with dCHIP and SAM programs to determine the significance of changes at the biological context.

View SamplesThe goal of the study was to characterize the molecular signatures of CD8 T cell subpopulations sorted from HIV+ lymph nodes and HIV- tonsils. We compared the transcriptome profiles of follicular and non -foliccular CD8 T cells (sorted based on the surface expression fo CCR7 and CXCR5, chemokine receptors that govern the intratissue trafficking of T cells). This is the first study addressing this question. We found several genes differentially expressed in these two CD8 T cell populations. Our pathway analysis revealed that several pathways related to costimulation/activation as well as to beta-catenin pathway were differentially expressed in these two CD8 t cell populations too. Overall design: CD8 T cell populations were sorted and whole transcriptome analysis was performed using an Illumina machine
Follicular CD8 T cells accumulate in HIV infection and can kill infected cells in vitro via bispecific antibodies.

View SamplesA toxicogenomic analysis from liver of different pharmacological active coumarins (mammea A/BA+A/BB 3:1 and soulatrolide ) was performed on mice treated (20mg/kg/daily) for a whole week to evaluate if such compounds possess or could develop a hazardous profile on liver.

View SamplesHow chromatin controls transcription elongation and splicing is an open question. Here we determine the transcriptomic changes of cells partially depleted of core histones. For that we construct a cell line with Doxycycline-controlled levels of the histone regulatory protein SLBP (HCT-shSLBP). HCT-shSLBP is derived from the human colon cancer cell line HCT116.
Defective histone supply causes changes in RNA polymerase II elongation rate and cotranscriptional pre-mRNA splicing.

View SamplesEpstein Barr virus causes linfectious mononucleosis and establishes lifelong infection associated with cancer and autoimmune disease. To better understand immunity to EBV, we performed a prospective study of natural infection in healthy humans. These anlyses were undertaken in order to determine what gene expression changes occur as the result of primary Epstein Barr virus infection. Samples were taken both before and following acquisition of the virus for direct comparison of samples for single subjects. These data provide an important first description of the response to natural herepesvirus infection in humans.

View SamplesWe identified RNA targets of Matrin3 using SH-SY5Y by PAR-CLIP analysis. Because Matrin3 mainly bound to intron of pre-mRNA, in order to find the effect of Matrin3 on splicing pattern and expression, we knocked down Matrin3 using SH-SY5Y cells by electroporation and extracted total RNAs from those cells. The total RNAs were subjected to whole transcripts microarray GeneChip Affymetrix Human Transcriptome array 2.0.
Matrin3 binds directly to intronic pyrimidine-rich sequences and controls alternative splicing.
