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.

Gene expression analysis in hLECs treated with gain of function or loss of function of MDK in human melanoma cells. Overall design: Biological triplicates of hLEC treated for 3 days with EGM-2 MV conditioned media of melanoma cells. Cell line SK-Mel-147 KD for MDK (shMDK) and its corresponding control (shCtrl (LoF) and WM164 cell line overexpressing MDK (MDK) or an empty vector (NEG) (GoF) were used to produce the conditioned media.

Description
Background: Changes in gene regulation are thought to be crucial for the adaptation of organisms to their environment. Transcriptome analyses can be used to identify candidate genes for ecological adaptation, but can be complicated by variation in gene expression between tissues, sexes, or individuals. Here we use high-throughput RNA sequencing of a single Drosophila melanogaster tissue to detect brain-specific differences in gene expression between the sexes and between two populations, one from the ancestral species range in sub-Saharan Africa and one from the recently colonized species range in Europe. Results: Relatively few genes (<100) displayed sexually dimorphic expression in the brain, but there was an enrichment of sex-biased genes, especially male-biased genes, on the X chromosome. Over 340 genes differed in brain expression between flies from the African and European populations, with the between-population divergence being highly correlated between males and females. The differentially expressed genes include those involved in stress response, olfaction, and detoxification. Expression differences were associated with transposable element insertions at two genes implicated in insecticide resistance (Cyp6g1 and CHKov1). Conclusions: Analysis of the brain transcriptome revealed many genes differing in expression between populations that were not detected in previous studies using whole flies. There was little evidence for sex-specific regulatory adaptation in the brain, as most expression differences between populations were observed in both males and females. The enrichment of genes with sexually dimorphic expression on the X chromosome is consistent with dosage compensation mechanisms affecting sex-biased expression in somatic tissues. Overall design: mRNA profiles of Drosophila melanogaster brains from adult males and females from a European and an African population (2 biological replicates each)

Description
Post-translational modifications of proteins by Small Ubiquitin-like Modifiers (SUMOs) regulate protein degradation and localization, protein-protein interaction, and transcriptional activity. SUMO E3 ligase functions are executed by SIZ1/SIZ2 in yeast and PIAS family members in human. The Arabidopsis genome contains only one gene, SIZ1, that is orthologous to yeast SIZ1/SIZ2. Here, we show that the Arabidopsis SIZ1 interacts with SUM1 and SCE1a, the SUMO E2 conjugating enzyme. Compared to WT, the null mutant siz-1-3 is smaller in statue because of reduced expression of gene involved in brassinosteroid biosynthesis and signalling. Drought stress induces the accumulation of SUMO-protein conjugates, which is in part dependent on SIZ1 but not on ABA. Mutant plants of siz1-3 have significant lower tolerance to drought stress. Genome wide expression analysis identified about 2,000 Arabidopsis genes that are responsive to drought, and SIZ1 mediates the induction of 600 of these genes by a pathway independent of DREB2A and ABA. SIZ1-dependent, drought-responsive genes include those encoding enzymes of the anthocyanin synthesis pathway and jasmonate response. From these results, we conclude that SIZ1 regulates Arabidopsis development and plays a role in drought stress response probably through the control of gene expression.

We report the role of LSM1-7 complex in the Arabidopsis tolerance to abiotic stresses. LSM1-7 controls gene expression reprogramming at the post-transcriptional level by promoting the decapping of mRNA. This function is selectively achieve over selected stress-induced transcripts depending on stress nature.

Description
Purpose: Aerobic capacity is a strong predictor of cardiovascular mortality. To determine the relationship between inborn aerobic capacity and soleus gene expression we examined genome-wide gene expression in soleus muscle of rats artificially selected for high and low running capacity (HCR and LCR, respectively) over 16 generations. The artificial selection of LCR caused accumulation of risk factors of cardiovascular disease similar to the metabolic syndrome seen in man, whereas HCR had markedly better cardiac function. We also studied alterations in gene expression in response to exercise training in the two groups, since accumulating evidence indicates that exercise has profound beneficial effects on the metabolic syndrome.
