Description
To profile the changes in the pattern of gene expression in human OCa cells induced by 1,25(OH)2D3, OVCAR3 cells were treated with 0.1 pM 1,25(OH)2D3 for 0, 8, 24 and 72 h. The cells were harvested, RNA was extracted, and Affmetrix microarrays were hybridized.

Description
The activity of enhancers and promoters fine-tunes the transcriptional program of mammalian cells through the recruitment and interplay between cell type-specific and ubiquitous transcription factors. Despite their key role in modulating transcription, the identification of enhancers is challenged by their limited sequence conservation and highly variable distance from target genes. Although enhancers are characterised by the strong enrichment of mono-methylation at lysine 4 of histone H3, mirrored by low tri-methylation at the same residue, a comprehensive list of enhancers-associated histone post-translational modifications (PTMs) is still lacking. We undertook a proteomics investigation, based on chromatin immunoprecipitation combined with mass spectrometry (MS), to identify histone marks specifically associated to cis-regulatory elements in macrophages, focusing on enhancers. We also profiled their plasticity during the transcriptional activation induced by an inflammatory stimulus. The proteomic analysis suggested novel PTM associations, which were validated by analysis of ChIP- and RNA-seq data, whose intersection revealed the existence of novel sub-populations of enhancers marked by specific signatures: the dual mark H3K4me1/K36me2 labels transcription at enhancers, whereas H3K4me1/K36me3 and H3K4me1/K79me2 tag distinct intronic enhancers. While demonstrating that analyzing restricted genomic regions can disclose the combinatorial language of histone modifications, this study highlights the potential of MS-based proteomics in addressing fundamental questions in epigenetics. Overall design: Total RNA was extracted from 5x10^6 untreated RAW 264.7 cells using RNAeasy kit (Qiagen). Libraries were then prepared using TruSeq RNA sample preparation Kit (Illumina) after depleting ribosomal RNA

Description
We generated genome-wide RNASeq data from freshly isolated airway epithelial cells of asthmatics and non-asthmatics. This data was paired with genome-wide genetic and methylation data from the same individuals allowing for an integrated analysis of genetic, transcriptional, and epigenetic signatures in asthma. Overall design: examination of genome-wide genome-wide gene expression levels and comparison to phenotypes

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The main goal of our study is to identify the molecular events that determine the gonadal identity in mammals. Although testis and ovary arise from a common embryonic primordium, they represent outcomes of opposing fate determination. This decision to differentiate into a testis or an ovary hinges upon the balance between two antagonizing factors, pro-testis SOX9 and pro-ovary -catenin.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The Human T-cell Leukemia Virus (HTLV)-type-I non-structural protein p30 plays an important role in virus transmission and gene regulation. p30 has been documented to inhibit the export of certain viral mRNA transcripts from the nucleus to the cytoplasm. This nuclear retainment of RNA molecules essentially results in gene silencing, where protein products are not produced.
Publication Title
Genome wide analysis of human genes transcriptionally and post-transcriptionally regulated by the HTLV-I protein p30.
