Affymetrix Maize Genome Array (maize)
Description
The maize inbred line A661 shows a characteristic phenotype when grown at suboptimal temperatures for three weeks and then is exposed to optimal temperatures for one extra week. After this period the third leaf showed two well defined sections: distal (chlorophyll-less; CL) and proximal (chlorophyll-containing; CC) sections. To further investigate the performance of the inbred line A661 under cold conditions a gene expression profiling analysis was conducted using large scale maize microarrays. A total of 1002 transcripts change their expression between both leaf sections and the majority of these codify for proteins located to the chloroplast.
Publication Title
Genetic regulation of cold-induced albinism in the maize inbred line A661.

Description
Oligodendrocytes are cells from the central nervous system that can be grouped into precursors, myelin-forming, and non-myelinating perineuronal. The function of perineuronal oligodendrocytes is unknown; it was suggested that they can ensheath denuded axons. We tested this hypothesis. Using cell-specific tags, microarray technology and bioinformatics tools to identify gene expression differences between these subpopulations allowed us to capture the genetic signature of perineuronal oligodendrocytes. Here we report that perineuronal oligodendrocytes are configured for a dual role. As perineuronal, they integrate a repertoire of transcripts designed to create a cell with its own physiological agenda. But they maintain a reservoir of untranslated transcripts encoding the major myelin proteins for we speculate a pathological eventuality. We posit that the signature molecules PDGFR-, cytokine PDGF-CC, and the transcription factor Pea3 used among others - to define the non-myelinating phenotype, may be critical for mounting a myelinating programme during demyelination. Harnessing this capability is of therapeutic value for diseases such as multiple sclerosis. This is the first molecular characterization of perineuronal oligodendrocytes.

Description
ZBTB4 is a mammalian transcription factor with Zinc fingers and a BTB/POZ domain, which can bind methylated CpGs, as well as certain unmethylated consensus sequences. ZBTB4 is frequently downregulated in human cancers, but it is unclear whether this is a cause or consequence of transformation. To investigate the role of ZBTB4 in normal and pathological conditions, we generated Zbtb4-/- mice

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Prion infection in animals results in neurodegeneration and eventually death. To examine the cellular impact of Prion disease, we profiled non-proliferative fully differentiated C2C12 cells, which can replicate prions to high levels. Results suggest that accumulation of high levels of PrPSc in C2C12 myotubes does not cause any overt cellular dysfunction or molecular pathology.

Description
The weaning period consist of a critical postnatal window for structural and physiologic maturation of rat beta cells. To investigate transcriptome changes involved in the maturation of beta cells neighboring this period we performed microarray analysis in FACS beta cell enriched populations to detail the global programme of gene expression to identify its changes during this process.
