Description
Our results suggest that 48h of immobilization increases expression of mRNA for components of the UPP and MT function while decreasing mRNA and protein for components involved in ECM integrity. We hypothesized that 48h of immobilization would increase gene expression and respective protein products for components of the ubiquitin proteasome pathway (UPP).

Description
Mesenchymal stem cell-derived extracellular vesicles (EVs) have been shown to promote angiogenesis in the ischemic myocardium. This study examines the difference in vascular density, myocardial perfusion, molecular signaling, and gene expression between normal diet (ND) and high fat diet (HFD) groups at baseline and following intra-myocardial injection of EVs

Description
The purpose of the study was to determine what genes in DN2 pro-T cells are immediately regulated by the transcription factor GATA-3, either as activation targets or as repression targets. To do this, two pairs of Gata3-floxed and control pro-T cells were generated and analyzed by RNA-seq within the first day of deletion of the Gata3 gene. Pro-T cells were generated by differentiation in vitro on OP9-DL1 monolayers of fetal liver-derive precursors from wildtype or Gata3-floxed mice, and the Gata3 gene was acutely deleted by transduction with Cre retroviral vector. Within 20 hr after transduction, samples of acutely Gata3-deleted and control DN2 cells were sorted and RNA prepared for RNA-seq analysis. High-throughput sequencing of the samples was carried out. Experimental Gata3 deleted samples in both cases were Gata3-floxed, ROSA26R-EYFP samples infected with Cre retrovirus and sorted for EYFP+ (Cre-activated) DN2 phenotype. Control for experiment 1: wildtype (C57BL/6) DN2 pro-T cells generated in parallel, also treated with Cre retrovirus but sorted only for DN2 phenotype. Control for experiment 2: same genotype as experimental, but infected with a GFP+ empty retroviral vector and sorted for GFP+ DN2 phenotype. Overall design: Two pairs of RNA-seq samples of DN2 pro-T cells were generated for comparison, each pair consisting of a Gata3-deleted sample plus a stage-matched control.

Description
Identification of blood biomarkers that prospectively predict Mycobacterium tuberculosis treatment response. Overall design: There are a total of 914 samples used in this design. This involves samples from 100 cases and 38 controls. Most of the samples have 2 technical replicates where as 2 samples have 4. Samples from the TB cases have been collected on the start day of TB treatment and on 1,4 and 24 weeks after treatment as well. For some subjects we also have samples after the subject has been cured. The case or TB Subjects have been categorized by the nature of their response as definite,probable or possible cure. The day of cure is presented in the time to negativity column. Also provided in the metadata are the MGIT -Mycobacteria Growth Indicator Tube and XPERT (cartridge based nucleic acid amplification test, automated diagnostic test that can identify Mycobacterium tuberculosis (MTB)) values at the various times of sample collection for all TB Subjects.

Description
Tibial muscular dystrophy (TMD) is a late onset, autosomal dominant distal myopathy that results from mutations in the two last domains of titin. The cascade of molecular events leading from the causative Titin mutations to the preterm death of muscle cells in TMD is largely unknown. To identify these components, we used gene expression profiling of muscle biopsies from TMD patients and healthy controls.

Description
Identification of blood biomarkers that prospectively predict progression of Mycobacterium tuberculosis infection to tuberculosis disease might lead to interventions that combat the tuberculosis epidemic. We aimed to assess whether global gene expression measured in whole blood of healthy people allowed identification of prospective signatures of risk of active tuberculosis disease. RESULTS:Between July 6, 2005, and April 23, 2007, we enrolled 6363 from the ACS study and 4466 from independent South African and Gambian cohorts. 46 progressors and 107 matched controls were identified in the ACS cohort. A 16 gene signature of risk was identified. The signature predicted tuberculosis progression with a sensitivity of 66·1% (95% CI 63·2–68·9) and a specificity of 80·6% (79·2–82·0) in the 12 months preceding tuberculosis diagnosis. The risk signature was validated in an untouched group of adolescents (p=0·018 for RNA sequencing and p=0·0095 for qRT-PCR) and in the independent South African and Gambian cohorts (p values <0·0001 by qRT-PCR) with a sensitivity of 53·7% (42·6–64·3) and a specificity of 82·8% (76·7–86) in 12 months preceding tuberculosis. Interpretation: The whole blood tuberculosis risk signature prospectively identified people at risk of developing active tuberculosis, opening the possibility for targeted intervention to prevent the disease. Overall design: In this prospective cohort study, we followed up healthy, South African adolescents aged 12–18 years from the adolescent cohort study (ACS) who were infected with M tuberculosis for 2 years. We collected blood samples from study participants every 6 months and monitored the adolescents for progression to tuberculosis disease. A prospective signature of risk was derived from whole blood RNA sequencing data by comparing participants who developed active tuberculosis disease (progressors) with those who remained healthy (matched controls). After adaptation to multiplex qRT-PCR, the signature was used to predict tuberculosis disease in untouched adolescent samples and in samples from independent cohorts of South African and Gambian adult progressors and controls. Participants of the independent cohorts were household contacts of adults with active pulmonary tuberculosis disease.
