A global understanding of the actions of the nuclear hormone 1α,25-dihydroxyvitamin D(3) (1α,25(OH)(2)D(3)) and its vitamin D receptor (VDR) requires a genome-wide analysis of VDR binding sites. In THP-1 human monocytic leukemia cells we identified by ChIP-seq 2340 VDR binding locations, of which 1171 and 520 occurred uniquely with and without(More)
BACKGROUND Microarray technologies are rapidly becoming available for new species including teleost fishes. We constructed a rainbow trout cDNA microarray targeted at the identification of genes which are differentially expressed in response to environmental stressors. This platform included clones from normalized and subtracted libraries and genes selected(More)
BACKGROUND High throughput methods of the genome era produce vast amounts of data in the form of gene lists. These lists are large and difficult to interpret without advanced computational or bioinformatic tools. Most existing methods analyse a gene list as a single entity although it is comprised of multiple gene groups associated with separate biological(More)
Alpha-synuclein containing cellular inclusions are a hallmark of Parkinson Disease, Lewy Body Dementia, and Multiple System Atrophy. A genome wide expression screen was performed in C. elegans overexpressing both wild-type and A53T human alpha-synuclein. 433 genes were up- and 67 genes down-regulated by statistical and fold change (> or <2) criteria. Gene(More)
The liver X receptors (LXRs) are oxysterol sensing nuclear receptors with multiple effects on metabolism and immune cells. However, the complete genome-wide cistrome of LXR in cells of human origin has not yet been provided. We performed ChIP-seq in phorbol myristate acetate-differentiated THP-1 cells (macrophage-type) after stimulation with the potent(More)
We present POXO, a comprehensive tool series to discover transcription factor binding sites from co-expressed genes (www.bioinfo.biocenter.helsinki.fi/poxo). POXO manages tasks such as functional evaluation and grouping of genes, sequence retrieval, pattern discovery and pattern verification. It also allows users to tailor analytical pipelines from these(More)

BACKGROUND The analysis of over-represented functional classes in a list of genes is one of the most essential bioinformatics research topics. Typical examples of such lists are the differentially expressed genes from transcriptional analysis which need to be linked to functional information represented in the Gene Ontology (GO). Despite the importance of(More)
BACKGROUND One essential step in the massive analysis of transcriptomic profiles is the calculation of the correlation coefficient, a value used to select pairs of genes with similar or inverse transcriptional profiles across a large fraction of the biological conditions examined. Until now, the choice between the two available methods for calculating the(More)
The basic helix-loop-helix protein BHLHE40 functions as a transcriptional repressor and is involved in the control of cellular growth, development and circadian rhythms. By the use of genome-wide data on vitamin D receptor (VDR) location, open chromatin and histone modification backed-up by gene-specific mRNA expression studies we show that the human(More)
