Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
We identified secreted frizzled-related protein-5 (Sfrp5) as a transcript that is upregulated during adipocyte differentiation and that is increased in white adipose tissue (WAT) of obese mice, compared to lean mice. To investigate the function of sFRP5 in adipose tissue biology, we studied sFRP5Q27stop mice, in which ENU mutagenesis was used to create a premature stop codon at Gln27, thereby creating a likely null allele.
Publication Title
Secreted frizzled-related protein 5 suppresses adipocyte mitochondrial metabolism through WNT inhibition.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
Because it excises thymine from GT mismatches, TDG was proposed to counter mutagenesis by 5-methylcytosine deamination. Yet, TDG was also observed to attack 5-methycytosine itself, making it a candidate DNA demethylase, and interactions with transcription factors implicated additional functions in gene regulation. Unlike other DNA glycosylases, TDG is essential for embryonic development. Fibroblasts from Tdg null embryos show massively impaired gene regulation, and this correlates with imbalanced histone modification and CpG methylation. TDG associates with the promoters of affected genes in MEFs and in embryonic stem cells, but epigenetic aberrations appear only in differentiated cells. TDG also contributes to the maintenance of active and bivalent chromatin during cell differentiation, using its DNA glycosylase activity to counter aberrant de novo methylation. Thus, TDG dependent DNA repair stabilizes epigenetic states during cell differentiation.

Embryonic lethal phenotype reveals a function of TDG in maintaining epigenetic stability.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
SW480 were stably transfected with an episomal plasmid expressing GFP and miRNA34 from a bidirectional doxycyclin regulatable promoter (Bornkamm et al Nucleic Acids Res. 2005 Sep 7;33(16)). Polyclonal cell lines were obtained by selection with Hygromycin at 350ug/ml for 10 days. The cell llnes identified as GFP only express GFP, whereas the cell lines identified as miRNA34a express both GFP and miRNA34 under doxycyclin control. For the present experiment, cells were treated with 1ug/ml Docycyclin for 72h. Cells were harvested and total RNA was isolated using Trizol (Invitrogen). After RNA cleanup (RNeasy, Qiagen) Affymetrix 133 Plus 2.0 micorarrays were hybridized using standard techniques.

Description
3 subtypes of cortical projection neurons were purified by fluorescence-activated cell sorting (FACS) at 4 different stages of development from mouse cortex. A detailed description of the data set is described in Arlotta, P et al (2005) and Molyneaux, BJ et al (2009). The hybridization cocktails used here were originally applied to the Affymetrix mouse 430A arrays and submitted as GEO accession number GSE2039. The same hybridization cocktails were then applied to the Affymetrix mouse 430 2.0 arrays, and those data are contained in this series.

Description
Mutations of the transcriptional regulator Mecp2 cause the X-linked autism spectrum disorder Rett syndrome (RTT), and Mecp2 has been implicated in several other neurodevelopmental disorders. To identify potential target genes regulated directly or indirectly by MeCP2, we performed comparative gene expression analysis via oligonucleotide microarrays on Mecp2-/y (Mecp2-null) and wild-type CPN purified via fluorescence-activated cell sorting (FACS).

Reduction of aberrant NF-κB signalling ameliorates Rett syndrome phenotypes in Mecp2-null mice.

Illumina HiSeq 2500
Description
How the various cell-types of the body achieve their specific shapes is fundamentally unknown. Here, we explore this issue by identifying genes involved in the elaboration of the complex, yet conserved, cellular morphology of Müller glial (MG) cells in the retina. Using genomic based strategies in zebrafish, we found more than 40 candidate genes involved in specific aspects of MG morphogenesis. The successive steps of cell morphogenesis correlate with the timing of the expression of cohorts of inter-related genes that have roles in generating the particular anatomical features of these cells, suggesting that a sequence of genetic regulomes govern stepwise cellular morphogenesis in this system. Overall design: 12 samples with three replicates each are provided. GFAP:GFP positive and negative cells were FAC sorted from wild type animals from each developmental stage
