- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
A role of vitamin C (ascorbic acid) as an antioxidant molecule has been recognized, largely based on in vitro studies. However, more recently, the concept of antioxidant molecule has been reconsidered and its biological function is no longer considered to be simply due to its ability to act as electron donors, rather, it appears to act by modulating signaling and gene expression.

Illumina HiSeq 2000
Description
strand specific sequencing of RNAs from MAoECs to determine the endothelial-specific expression profile of protein-coding and long non-coding RNAs Overall design: Total RNA was isolated from cultured MAoECs (passage 4) and processed for a strand-specific RNA sequencing. The RNA purity and integrity were assessed using the Fragment Analyzer Automated CE System (Advanced Analytical). A RQN of 8.8 and a 28S/18S ratio of 2.2 were considered acceptable for next generation sequencing assay. Five µg of DNase-treated RNA were used to prepare Massive Analysis of cDNA ends (MACE) libraries needed to perform a DNA-Methylation-Sequencing (Meth-Seq) PCR bias free quantification with TrueQuant Technology, followed by a high-throughput sequencing on the Illumina Genome Analyzer II system (GenXPro GmbH, Frankfurt, Germany). The procedure consist in the extraction of poly-adenylated RNA from 5 µg RNA and reverse transcribed with biotinylated poly(T) primers. cDNA is fragmented to an average size of 250 bp. Biotinylated ends are captured by streptavidin beads and ligated to modified adapters (TrueQuant DNA adapter, GenXPro). The libraries are amplified by PCR, purified by SPRI beads and sequenced (2 x 100 bp Illumina HiSeq2000 TrueSeq, 2 x 20 Mio. Reads poly-A selected paired-end reads). Paired end sequencing of both DNA strands from each end is required for fragment strand specificity.

Description
Unraveling the complexity of transcriptional programs coded by different cell types has been one of the central goals of cell biology. Using genome-wide location analysis, we examined how two different cell types generate different responses to the NF-kappaB signaling pathway. We showed that, after tumor necrosis factor-alpha (TNF-alpha) treatment, NF-kappaB p65 subunit binds to distinct genome locations and subsequently induces different subsets of genes in human monocytic THP-1 cells versus HeLa cells . Interestingly, the differential p65 binding in two cell types correlates with pre-existing cell-type specific enhancers prior to TNF-alpha stimulation, marked by histone modifications. We also found that two transcription factors, PU.1 and C/EBPalpha, appear to synergistically mediate enhancer creation and affect NF-kappaB target selection in THP-1 cells. In HeLa cells, co-expression of PU.1 and C/EBPalpha conferred TNF-alpha responsiveness to a subset of THP-1 specific NF-kappaB target genes. These results suggest that the diversity of transcriptional programs in mammalian cells arises, at least in part, from pre-existing enhancers that are established by cell specific transcription factors.

Description
Both genetic and environmental factors are implicated in Type 1 Diabetes (T1D). Since environmental factors can trigger epigenetic changes, we hypothesized that variations in histone posttranslational modifications (PTMs) at the promoter/enhancer regions of T1D susceptible genes may be associated with T1D. We therefore evaluated histone PTM variations at known T1D susceptible genes in blood cells from T1D patients versus healthy non-diabetic controls, and explored their connections to T1D. We used the chromatin-immunoprecipitation-linked-to-microarray approach to profile key histone PTMs, including H3-lysine-4 trimethylation (H3K4me3), H3K27me3, H3K9me3, H3K9 acetylation (H3K9Ac) and H4K16Ac at genes within the T1D susceptible loci in lymphocytes, and H3K4me3, H3K9me2, H3K9Ac and H4K16Ac at the IDDM1 region in monocytes of T1D patients and healthy controls separately. We screened for potential variations in histone PTMs using computational methods to compare datasets from T1D and controls. Interestingly, we observed marked variations in H3K9Ac levels at the upstream regions of HLA-DRB1 and HLA-DQB1 within the IDDM1 locus in T1D monocytes relative to controls. Additional experiments with THP-1 monocytes demonstrated increased expression of HLA-DRB1 and HLA-DQB1 in response to interferon- and TNF-treatment that were accompanied by changes in H3K9Ac at the same promoter regions as that seen in the patient monocytes. These results suggest that the H3K9Ac status of HLA-DRB1 and HLA-DQB1, two genes highly associated with T1D, may be relevant to their regulation and transcriptional response towards external stimuli. Thus, the promoter/enhancer architecture and chromatin status of key susceptible loci could be important determinants in their functional association to T1D susceptibility.
