- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin. However, the pleiotropic effects of auxin or auxin-like molecules on root systems complicate the study of lateral root development. Here we describe a small-molecule screen in Arabidopsis thaliana that identified naxillin as what is to our knowledge the first non-auxin-like molecule that promotes root branching. By using naxillin as a chemical tool, we identified a new function for root cap-specific conversion of the auxin precursor indole-3-butyric acid into the active auxin indole-3-acetic acid and uncovered the involvement of the root cap in root branching. Delivery of an auxin precursor in peripheral tissues such as the root cap might represent an important mechanism shaping root architecture. To further explore the specificity of naxillin for lateral root development, we compared the early effects of naxillin at the transcriptome level with NAA (1-Naphthaleneacetic acid) in roots of 3-day-old seedlings after 2-h and 6-h treatment.

Illumina Genome Analyzer II, Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
We performed ChIP-Seq analysis of SOX10, histone H3 lysine 27 acetylation (H3K27ac) and H3K27 trimethylation (H3K27me3) in melanocytes to profile the genomic binding sites of SOX10 and the chromatin landscape. In parallel, we generated Sox10 haploinsufficient cell lines using gene knockout approaches and conducted microarray gene expression analysis to identify functional gene targets of SOX10 transcriptional regulation in melanocytes. We demonstrate that SOX10 predominantly engages open chromatin, binds to melanocyte enhancer elements and plays a central role in transcriptional activation and repression of functionally distinct classes of genes. Furthermore, we identified cis-regulatory sequence motifs of putative co-regulatory transcription factors that define SOX10-activated and SOX10-repressed target genes. Our results uncover novel mechanisms and roles of SOX10 in global transcriptional regulation of diverse regulatory pathways in the melanocyte lineage.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Characterization of genes associated with adipose tissue is key to understanding the pathogenesis of obesity and developing treatments for this disorder. Differential gene expression in the adipose tissue has been described in adulthood but none studies have been developed on childhood. The purpose of this study was to compare gene expression in omental adipose tissue from obese prepubertal and normal weight children. We selected 5 obese (BMI adjusted for age and sex z score >2) and 6 normal weight children. RNA was extracted from omental adipose tissue biopsies and cRNA was hybridizated on the human genome U133 Plus 2.0 Arrays (Affymetrix). Microarray experiments were performed for each sample, and selected group of gene expression values were confirmed with real-time RT-PCR in 10 obese and 10 normal weigth prepubertal children. 1276 genes were found to be differentially expressed at P<0.05. Of those differential genes, 201 were upregulated (Fc>2) and 42 were downregulated (Fc<-2). Genes involved in metabolic and signalling pathways were altered in childhood obesity.
