Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
BACKGROUND: Understanding individual patient host response to viruses is key to designing optimal personalized therapy. Unsurprisingly, in-vivo human experimentation to understand individualized dynamic response of the transcriptome to viruses are rarely studied because of the obvious limitations stemming from ethical considerations of the clinical risk.

Description
High fat feeding is deleterious for skeletal muscle metabolism, while exercise has well documented beneficial effects for these same metabolic features. To identify the genomic mechanisms by which exercise ameliorates some of the deleterious effects of high fat feeding, we investigated the transcriptional and epigenetic response of human skeletal muscle to 9 days of a high-fat diet (HFD) alone (Sed-HFD) or in combination with resistance exercise (Ex-HFD), using genome-wide profiling of gene expression (by RNA-seq) and DNA methylation (by Reduced Representation Bisulfite Sequencing). HFD markedly induced expression of immune and inflammatory genes which was not attenuated by Ex. In contract, Ex markedly remodelled expression of genes associated with muscle growth and structure. We detected marked DNA methylation changes following HFD alone and in combination with Ex. Among the genes that showed significant association between DNA methylation changes and gene expression were glycogen phosphorylase, muscle associated (PYGM), which was epigenetically regulated in both groups, and angiopoiten like 4 (ANGPTL4), which was regulated only following Ex. We conclude that Short-term Ex does not prevent HFD-induced inflammatory response, but provokes a genomic response that may preserve skeletal muscle from atrophy. Epigenetic adaptation provides important mechanistic insight into the gene specific regulation of inflammatory and metabolic processes in human skeletal muscle. Overall design: Sedentary or exercising human subjects undergo high-fat diet intervention.

Description
Pax6 is a highly conserved transcription factor among vertebrates and is important in various aspects of the central nervous system (CNS) development. However, the gene regulatory circuitry of Pax6 underlying these functions remains elusive. We find that, following expression in neural progenitor cells, Pax6 targets many promoters embedded in an active chromatin environment. Intriguingly, many of these sites are also bound by another progenitor factor, Sox2, which cooperates with Pax6 in gene regulation. A combinatorial analysis of Pax6 binding dataset with transcriptome changes in Pax6-deficient neural progenitors reveals a dual role for Pax6, in which it activates the neuronal (ectodermal) genes while concurrently represses the mesodermal and endodermal genes thereby ensuring the unidirectionality of lineage commitment towards glutamatergic neuronal differentiation. Furthermore, Pax6 is critical for inducing activity of transcription factors that elicit neurogenesis and repress others that promote non-neuronal lineages. In addition to many established downstream effectors, Pax6 directly binds and activates a number of genes that are specifically expressed in neural progenitors but have not been previously implicated in neurogenesis. The in utero knockdown of one such gene, Ift74, during brain development impairs polarity and migration of new-born neurons. These findings demonstrate new aspects of the gene regulatory circuitry of Pax6, revealing how it functions to control neuronal development at multiple levels to ensure unidirectionality and proper execution of the neurogenic program.

Description
Rapid nerve conduction in the CNS is facilitated by the insulation of axons with myelin, a specialized oligodendroglial compartment distant from the cell body. Myelin is turned over and adapted throughout life; however, the molecular and cellular basis of myelin dynamics is not well understood. Hypothesizing that only a fraction of all myelin-related mRNAs has been identified so far, we subjected myelin biochemically purified from mouse brains at various ages to RNA sequencing. We find a surprisingly large pool of transcripts abundant and/or enriched in myelin. Furthermore, a comprehensive analysis showed that the myelin transcriptome is closely related to the myelin proteome but clearly distinct from the transcriptomes of oligodendrocytes and brain tissues, suggesting that the incorporation of mRNAs into the myelin compartment is highly selective. The mRNA-pool in myelin displays maturation-dependent dynamic changes of composition, abundance, and functional associations; however ageing-dependent changes after 6 months of age were minor. We suggest that this transcript pool provides a basis for the local modulation of myelin turnover and adaptation, i.e. in the individual internode. Overall design: A light-weight membrane fraction enriched for myelin was purified from mouse brains as described previously (Jahn et al., Neuromethods, 2013). For RNA-Seq, RNA was isolated from myelin of mice from indicated ages.

Description
Whole genome sequencing revealed CLL as a disease of the genome and epigenome defined by somatic mutations and aberrant DNA-methylation. To uncover the impact of aberrant methylation on transcription, gene expression and methylation array profiling was performed in CLL and B-cells. RNA from 13 CLL patients and 6 healthy donor samples was analyzed on expression arrays.
