View SamplesBackground: With less than a 5% survival rate pancreatic adenocarcinoma (PDAC) is almost uniformly lethal. In order to make a significant impact on survival of patients with this malignancy, it is necessary to diagnose the disease early, when curative surgery is still possible. Detailed knowledge of the natural history of the disease and molecular events leading to its progression is therefore critical.

View SamplesDNA methylation is an essential epigenetic modification, present in both unique DNA sequences and repetitive elements, but its exact function in repetitive elements remains obscure. Here, we describe the genome-wide comparative analysis of the 5mC, 5hmC, 5fC and 5caC profiles of repetitive elements in mouse embryonic fibroblasts and mouse embryonic stem cells. We provide evidence for distinct and highly specific DNA methylation/oxidation patterns of the repetitive elements in both cell types, which mainly affect CA repeats and evolutionary conserved mouse-specific transposable elements including IAP-LTRs, SINEs B1m/B2m and L1Md-LINEs. DNA methylation controls the expression of these retro-elements, which are clustered at specific locations in the mouse genome. We show that TDG is implicated in the regulation of their unique DNA methylation/oxidation signatures and their dynamics. Our data suggest the existence of novel epigenetic code for the most recently acquired evolutionary conserved repeats that could play a major role in cell differentiation. Overall design: Transcriptome (RNA-seq) analyses of shRNA treated MEFs (control, shSCR or Tdg knockdown, shTDG).

View SamplesDuring development, neural crest cells are induced by signaling events at the neural plate border of all vertebrate embryos. Initially arising within the central nervous system, NC cells subsequently undergo an epithelial to mesenchymal transition to migrate into the periphery, where they differentiate into diverse cell types. Here we provide evidence that postnatal human epidermal keratinocytes, in response to FGF2 and IGF1 signals, can be reprogrammed toward a neural crest fate. Genome-wide transcriptome analyses show that keratinocyte-derived NC cells are similar to those derived from human embryonic stem cells. Moreover, they give rise in vitro and in vivo to neural crest derivatives such as peripheral neurons, melanocytes, Schwann cells and mesenchymal cells (osteocytes, chondrocytes, adipocytes and smooth muscle). By demonstrating that human KRT14+ keratinocytes can form neural crest cells, even from clones of single cells, our results have important implications in stem cell biology and regenerative medicine. Overall design: mRNA profiles of KC and KC derived NC (from 3 biological replicates) were generated by deep sequencing using Illumina HiSeq 2500 platform (pair-end (2x50 bp) rapid run mode).

View SamplesWe identify regulatory mechanisms that influence inflammation and metabolism during metabolic disease development. In addition to the other data represented in our paper, we performed RNA-seq to demonstrate a role for miR-146a, an anti-inflammatory miRNA, in regulating both inflammation and cellular metabolism during obesity. Overall design: Each sample represents pooled cells from three mice of the same genotype and treatment group. Samples were pooled before FACS to ensure sufficient cell numbers for sorting and RNA collection. WT or miR-146a-/- mice were treated with either high fat diet or normal chow diet for 14 weeks starting from 6 weeks of age. Mice were sacrificed and live, singlet CD45+ CD11b+ F4/80+ cells were sorted from the stromal vascular fraction of adipose tissue using FACS Aria. RNA was collected from the sorted cells via Qiazol/RNeasy Kit (Qiagen) and library preparation used Illumina TruSeq Stranded RNA Kit with Ribo-Zero Gold. RNA-seq was performed using Illumina HiSeq 50 cycle single-read sequencing version 4. Sequence alignment was performed through the University of Utah Bioinformatics Core Facility.
