Affymetrix Plasmodium/Anopheles Genome Array (plasmodiumanopheles)
Description
With their genome sequenced, Anopheles gambiae mosquitoes now serve as a powerful tool for basic research in comparative, evolutionary and developmental biology. The knowledge generated by these studies is expected to reveal molecular targets for novel vector control and pathogen transmission blocking strategies. Comparisons of gene-expression profiles between adult male and nonblood-fed female Anopheles gambiae mosquitoes revealed that roughly 22% of the genes showed sex-dependent regulation. Blood-fed females switch the majority of their metabolism to blood digestion and egg formation within 3 h after the meal is ingested, in detriment to other activities such as flight and response to environment stimuli. Changes in gene expression are most evident during the first, second and third days after a blood meal, when as many as 50% of all genes showed significant variation in transcript accumulation. After laying the first cluster of eggs (between 72 and 96 h after the blood meal), mosquitoes return to a nongonotrophic stage, similar but not identical to that of 3-dayold nonblood-fed females. Ageing and/or the nutritional state of mosquitoes at 15 days after a blood meal is reflected by the down-regulation of 5% of all genes. A full description of the large number of genes regulated at each analysed time point and each biochemical pathway or biological processes in which they are involved is not possible within the scope of this contribution. Therefore, we present descriptions of groups of genes displaying major differences in transcript accumulation during the adult mosquito life. However, a publicly available searchable database (Anopheles gambiae Gene Expression Database at UC Irvine) has been made available so that detailed analyses of specific groups of genes based on their descriptions, functions or levels of gene expression variation can be performed by interested investigators according to their needs.

Illumina HiSeq 2500
Description
We report RNA sequencing data from tenocytes treated with IGF1. Tenocytes were obtained from the tail tendons of adult C57Bl/6 mice via collagenase digestion. Tenocytes were grown to 60% confluence, and then treated with 100ng/mL of recombinant IGF1 for a period of 0, 1, 2, 6, or 24 hours. Experiments were conducted in quadruplicate. RNA was isolated and prepared for RNA sequencing. Overall design: Differential expression of mRNAs were evaluated from tenocytes isolated from tail tendons of adult wild type C57Bl/6 mice that were treated with recombinant IGF1 for 0, 1, 2, 6, and 24 hours.
Publication Title
Insulin-like growth factor 1 signaling in tenocytes is required for adult tendon growth.

Description
To obtain a comprehensive view of genes contributing to long-term memory we performed mRNA sequencing from single Drosophila heads following behavioral training that produces long-lasting memory. Overall design: Drosophila trained with an appetitive conditioning paradigm using Sucrose were collected prior to starvation, training, and 1 or 4 hours post-training, 5 to 6 replicates each, for RNA-Seq analysis of the fly heads with an Illumina HiSeq 2000.

- Affymetrix Mouse Gene 2.1 ST Array (mogene21st)
Description
Platelet-derived growth factor receptor (PDGFR) signaling plays an important role in the embryonic formation of many different tissues. There is a family of PDGF isoforms which signal through the PDGF receptors (PDGFR) and (PDGFR). PDGF regulates many key cellular processes of mesenchymal cell function including proliferation, differentiation, migration and extracellular matrix (ECM) synthesis. While PDGF has been used to enhance flexor tendon healingin vivo, its role in postnatal tendon growth has remained largely unexplored. To determine the importance of PDGFR signaling in postnatal tendon growth, we performed pharmacological blockade of PDGFR and PDGFR, and then induced tendon growth via mechanical overload using the hindlimb synergist ablation model. Our hypothesis was that inhibition of PDGFR signaling will restrict normal growth of tendon tissue in response to mechanical loading.

Description
Rett syndrome (RTT, OMIM #312750) is a severe X-linked neurodevelopmental disorder linked to heterozygous de novo mutations in the MECP2 gene. MECP2 encodes methyl-CpG-binding protein 2 (MeCP2), which represses gene transcription by binding to 5-methylcytosine residues in symmetrically positioned CpG dinucleotides. The disorder is almost exclusively diagnosed in females, because males affected by the disease usually die perinatally due to severe encephalopathy. Direct MeCP2 target genes underlying the neuropathogenesis of RTT remain largely unknown.
Publication Title
FXYD1 is an MeCP2 target gene overexpressed in the brains of Rett syndrome patients and Mecp2-null mice.

- Affymetrix Chicken Genome Array (chicken)
Description
Comparative analysis of gene expression profiles in newly developed housing systems is important to understand gene functions in chicken for adaptation and possible gene-environment interactions among layer lines. Therefore, the objective of this study was to characterize the molecular processes that are different among the two layer lines Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) using whole genome RNA expression profiles. Despite their approximately identical egg production performance these layer lines differ markedly in other phenotypic traits. The two layer lines were kept under the production environment of the newly developed small group housing system Eurovent German with two different group sizes and three tiers.

Differential gene expression from genome-wide microarray analyses distinguishes Lohmann Selected Leghorn and Lohmann Brown layers.

Description
To address the functional role of KDM6A in the regulation of Rhox genes, male and female mouse ES cells were transfected with a mixture of three small interfering RNA duplexes, each of which targets a different region of Kdm6a mRNA. We found that Kdm6a knockdown in mouse ES cells caused a decrease in expression of a subset of Rhox genes, Rhox6 and 9. Furthermore, Rhox6 and 9 expression was decreased in female ES cells but not male ES cells indicating that KDM6A regulates Rhox gene expression in a sexually dimorphic manner.
Publication Title
