Description
We report a pilot investigation for poly-A RNAs differentially expressed during Mycobacterium tuberculosis infection. Participation in this investigation from March 2010 to July 2013 was voluntary, only subjects that were >18 years old and that informed written consent were considered eligible. The recruitment of tuberculosis (TB) patients was done at public hospitals in Rio de Janeiro, Brazil. The diagnostic criteria for active pulmonary tuberculosis was at least one AFB (acid-fast bacilli) -positive sputum sample for M. tuberculosis and/or positive sputum culture and/or compatible clinical evolution for pulmonary TB and less than 15 days of anti-TB treatment and was in accordance with those of the Brazilian Ministry of Health. Blood was collected from recent close contacts (rCt) and active tuberculosis (TB) index cases (n=6). Latent TB infection (LTBI) was accessed by both tuberculin skin test (TST, cut-off = 5mm) and in house interferon-gamma release assays (IGRA, cut-off = 100 pg/ml), therefore, 12 rCt were classified as uninfected controls and 16 with LTBI. Subsequently, the sequencing was performed following the standard protocols on Illumina HiSeq® 2500 Sequencing System (Illumina, San Diego, CA) running 100 bp paired-end reads (PE100) and generating approximately 30 million reads passing filter for each sample to produce the mRNA reads. Mining these RNAseq data, highly prominent modulation of DOCK9, EPHA4, and NPC2 mRNA expression was observed in the TB samples, indicating that they might have a role in TB pathogenesis. These differential modulations upon M. Tuberculosis infection were further validated by additional evidences in larger cohorts from different geographical areas. Overall design: We collected blood samples from the recent close contacts (rCt) at the recruitment and monitored them for 1-year. All TB participants were treatment-naïve. An infection mRNA signature was derived from whole blood RNA sequencing data by comparing TB and uninfected rCt. We selected the 3 most prominent genes, by area under the ROC curve analysis, for additional validations. Some of the LTBI participants also showed the mRNA infection profile.

Description
Mutations in the enzymes IDH1 and IDH2 have been identified in a wide variety of tumors like glioma, chondrosarcoma, thyroid cancer, lymphoma, melanoma, and in acute myeloid leukemia. Mutated IDH1/2 produces the metabolite 2-hydroxyglutarate (2HG), which interferes with epigenetic regulation of gene expression, and thus may promote tumorigenesis.

Description
Oxidized phospoholipids are a pro-inflammatory component of minimally modified lipoproteins that get trapped in the subendothelial space of atherosclerotic plaques of large arteries. To model the response of endothelial cells in a pro-atherosclerotic enviroment we measured the expression in primary endothelial cells with and without treatment with oxidized phsopolipids from 96 genetically identical donors of anonymous origin.

Description
Mutations in the gene encoding the transcription factor forkhead box P1 or FOXP1 occur in patients with neurodevelopmental disorders, including autism. However, the function of FOXP1 in the brain remains mostly unknown. Here, we identify the gene expression program regulated by FoxP1 in both human neural cells and mouse brain and demonstrate a conserved role for FOXP1 transcriptional regulation of autism and Fragile X Mental Retardation Protein (FMRP) mediated pathways. Coexpression networks support a role for Foxp1 in neuronal activity, and we show that Foxp1 is necessary for neuronal excitability. Using a Foxp1 mouse model, we observe defects in ultrasonic vocalizations. This behavioral phenotype is reflected at the genomic level as striatal Foxp1-regulated overlap with genes known to be important in rodent vocalizations. These data support an integral role for FOXP1 in regulating signaling pathways vulnerable in developmental disorders and the specific regulation of pathways important for vocal communication. Overall design: We carried out RNA-sequencing (RNA-seq) and ChIP-sequencing of human neural progenitors cells. We carried out RNA-sequencing (RNA-seq) of mouse striatal tissue, mouse hippocampal tissue and mouse cortical tissue. For the RNA-seq, four indipendent replicates were used for the neural progenitor cells and mouse tissues. For the Chip-seq, a single neural progenitor cell line was used.

Description
The conserved RNA-binding protein Musashi1 (MSI1) has emerged as a key oncogenic factor in numerous solid tumors, including glioblastoma. However, its mechanism of action has not yet been established comprehensively. We set out to map its impact on the transcriptome in U251 cells using RNA-seq and iCLIP. Overall design: Examination of gene expression and splicing changes upon KD of Musashi1 in U251 cells and link to iCLIP-identified Musashi1 RNA binding sites

Description
Bovine leukemia virus (BLV) Tax is a transcriptional activator of viral replication and a key contributor to oncogenic potential. We previously identified interesting mutant forms of Tax with elevated (TaxD247G) or reduced (TaxS240P) transactivation effects on BLV replication and propagation. In this study, to identify genes that play a role in the cascade of signal events regulated by wild-type and mutant Tax proteins, we used a large-scale host cell gene-profiling approach.
