Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Platelet-derived growth factor-C (PDGF-C) is one of three known ligands for the tyrosine kinase receptor PDGFR. Analysis of Pdgfc null mice has demonstrated roles for PDGF-C in palate closure and the formation of cerebral ventricles, but redundancy with other PDGFR ligands might hide additional functions. In search of further developmental roles for PDGF-C, we generated mice that were double mutants for Pdgfc -/- and Pdgfra GFP/+. These mice display a range of severe phenotypes including cerebellar malformation, neuronal over-migration in the cerebral cortex, spina bifida and lung emphysema. We focused our analysis on the central nervous system (CNS), where PDGF-C was identified as a critical factor for the formation of meninges and assembly of the glia limitans basement membrane.

Description
Adipocyte precursor cells were treated with Pdgfa during 1 or 2 hours in vitro to identify early changes in transciprion in response to treatment. This experiment supports the evidence that Pdgfa induces proliferation and maintenance of adipocyte stem cells. Overall design: Adipocyte precursor cells were isolated by FACS and treated with 30ng/ml of recombinant mouse Pdgfa for 1 or 2 hours.

Description
Embryonic stem (ES) cells have a remarkable capacity to self-organize complex, multi-layered optic cups in vitro via a culture technique called SFEBq. During both SFEBq and in vivo optic cup development, Rax (Rx) expressing neural retina epithelial (NRE) tissues utilize Fgf and Wnt/ß-catenin signalling pathways to differentiate into neural retina (NR) and retinal-pigmented epithelial (RPE) tissues, respectively. How these signaling pathways affect gene expression during optic tissue formation has remained largely unknown, especially at the transcriptome scale. Overall design: We generated Day 10 Rx+ optic tissue using SFEBq, exposed these tissues to either Fgf or Wnt/ß-catenin stimulation, and assayed their gene expression at Days 12 and 15 using RNA-Seq. We measured gene expression in these 5 sample groups in biological triplicate using RNA-seq (Illumina HiSeq) .

Description
Cockayne syndrome (CS) is an autossomal human disorder characterized by premature aging along with other symptoms. At the molecular level, CS is characterized by a deficiency in the Transcription-couple DNA repair pathway caused by a mutation mainly in ERCC6 gene and the absence of its functional protein. It has been shown that the presence of DNA damage and the lack of some functional proteins related to DNA repair constitute a barrier for somatic cell reprogramming. Recently, it was demonstrated that one protein involved in Genome Global Repair controls the expression of an important pluripotent gene, highligting its importance for cellular reprogramming.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Maternal obesity during the pre-implantation period leads to a pro-inflammatory milieu in the ovaries. We conducted a global transcriptomic profiling in ovaries from TEN fed rats during the pre-implantation period. Microarray analysis revealed that obesity lead to increased expression of genes related to inflammation, decreased glucose transporters, and dysregulation of ovarian function-related genes in the ovaries. Our results suggest maternal obesity led to an up-regulation of inflammatory genes and Egr-1 protien expression in peri-implantation ovarian tissue, and a concurrent down-regulation of glucose transporters mRNA and AKT and PI3K protein levels.
Publication Title
Maternal obesity is associated with ovarian inflammation and upregulation of early growth response factor 1.

Description
The simultaneous genotyping of tens of thousands of SNP using SNP microarrays is a very important tool that is revolutionizing genetics and molecular biology. In this work, we present a new application of this technique by using it to assess chromatin immunoprecipitation (CHIP) as a means to assess the multiple genomic locations bound by a protein complex recognized by an antibody. We illustrate the use of this technique with an analysis of the change in histone H4 acetylation, a marker of open chromatin and transcriptionally active genomic regions, which occur during the differentiation of human myoblasts into myotubes. Our results are validated by the observation of a significant correlation between the histone modifications detected and the expression of the nearby genes, as measured by DNA microarrays.
