Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The ductus arteriosus (DA) is a fetal vascular shunt that is located between the main pulmonary artery and the aorta. Oxygenated fetal blood from the placenta is shunted past the uninflated fetal lungs, crosses the DA, and is then available to the peripheral organs. In utero closure of the DA is deleterious, but postnatal closure of the DA is necessary for establishment of pulmonary circulation and the transition to newborn life.
Publication Title
Transcriptional profiling reveals ductus arteriosus-specific genes that regulate vascular tone.

Description
DNA 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).

Description
miRNA-1343 is an uncharacterized miRNA predicted to target a number of genes involved in epithelial cell function including TGF-beta signaling, cell adhesion, and cell proliferation. We transiently overexpressed miRNA-1343 or a non-targeting control miRNA in A549 and 16HBE14o- human airway cell lines. As predicted, RNA-seq following miRNA-1343 overexpression showed significant downregulation of genes involved in these pathways. Furthermore, genes involved in cholesterol and lipid biosynthesis were found to be significantly upregulated by miRNA-1343 overexpression. Overall design: mRNA profiles from A549 and 16HBE14o- cells transiently transfected with miRNA-1343 or a negative control (NC) miRNA, in quintuplicate.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
ARC (NSC 188491, SMA-491), 4-amino-6-hydrazino-7-beta-d-ribofuranosyl-7H-pyrrolo-(2,3-d)-pyrimidine-5-carboxamide, is a nucleoside analog with profound in vitro anti-cancer activity. First identified in a high-throughput screen for inhibitors of p21 mRNA expression, subsequent experiments showed that ARC also repressed expression of hdm2 and survivin, leading to its classification as a global inhibitor of transcription 1. The following Hu U133 plus 2.0 arrays represent single time point (24 hour) gene expression analysis of transcripts altered by ARC treatment. Arrays for the other compounds (sangivamycin and doxorubicin) are included as comparators.
Publication Title
ARC (NSC 188491) has identical activity to Sangivamycin (NSC 65346) including inhibition of both P-TEFb and PKC.

Description
Purpose: The goal of this study is to compare the differential expression of transcripts in control kidneys compared to kidneys lacking the miR-17~92 cluster in nephron progenitors and their derivatives by RNA-seq to identify potential miRNA targets in the mutant kidneys. Overall design: mRNA profiles of control and mutant (=Six2-TGC; miR-17~92 flx/flx) embryonic day 16 kidneys were generated by deep sequencing, in triplicate, using Illumina HiSeq2000
Publication Title
MicroRNA-17~92 is required for nephrogenesis and renal function.
