TranscriptomicsExpression data of HUVEC cells after TNF-alpha treatment
Tumor necrosis factor a (TNF-aplha) is a potent cytokine that orchestrates the inflammatory response by sequentially activating the expression of many genes in cultured human umbilical vein cells (HUVECs). We apply samples collected every 7.5 min to arrays and monitor the growth of several long tran...

TranscriptomicsRec8 guides canonical Spo11 distribution along yeast meiotic chromosomes
Spo11-mediated DNA double strand breaks (DSBs) that initiate meiotic recombination are temporally and spatially controlled. The meiotic cohesin Rec8 has been implicated in regulating DSB formation, but little is known about the features of their interplay. To shed light on this point, we investigate...

TranscriptomicsGlobal expression analysis of HNF4alpha and HNFgamma-mediated transcriptional control
Hepatocyte nuclear factor-4α (HNF4α, NR2A1) is a nuclear receptor which has a critical role in hepatocyte differentiation and the maintenance of homeostasis in the adult liver. However, a detailed understanding of native HNF4α in the steady state remains to be elucidated. Here we report the native H...

TranscriptomicsIntegrated array-CGH and expression microarray analyses on medulloblastomas in heterozygous Ptch1 mice, expression
Genomic radiation signature illuminates low-dose effects with sharply reflected transcriptome in Ptch1-deficient medulloblastomas. Cancer risks of low-dose radiation are of great concern especially in relation to rapidly increasing medical exposures; however, their accurate assessments cope with man...

TranscriptomicsTime course of localization of histone modifications, insulators, RNA polymerase II on TNF alpha responsive genes
The many modifications involved in transcription are extensively coupled, and levels of histone modifications, insulators, and RNA polymerase II could be measured using genomic tiling microarrays. After 0, 30, 60 min of stimulation of HUVEC with TNF alpha, we crosslinked cells and fixed, then immuno...

TranscriptomicsPITX1 suppresses TERT transcription
Using microcell-mediated chromosome transfer (MMCT) into the mouse melanoma cell line, B16F10, we have previously found that human chromosome 5 carries a gene, or genes, that can negatively regulate TERT expression. To identify the gene responsible for the regulation of TERT transcription, we perfor...
