Project description:We treated lymphoblast cells with the iron chelator deferoxamine (DFO) for 60 hours to determine if iron chelation would affect the levels of intron lariats.
Project description:The data describe longitudinal profiling, pre and post treatment of a human B lymphoblastoid cell line (B-LCL). The cells were treated with Everolimus at timepoint 7 and the full untargeted proteomics and transcriptomics were profiled over a total of 24 timepoints (over 12 hours), with samples acquired once every half-hour. A validation experiment was repeated as a separate experiment using a subset of the time points.
Project description:Transcriptional profiling of human lymphoblastoid TK6 cells comparing mock irradiated cells with cells exposed 24 hours previously to 1.67 Gy HZE (1 GeV/amu iron ions accelerated at the NASA Space Research Laboratory (NSRL) of Brookhaven National Laboratory) or 2.5 Gy 137Cs gamma rays.
Project description:This SuperSeries is composed of the following subset Series: GSE16518: Response of human lymphoblastoid cells to HZE (iron ions) or gamma-rays GSE16519: Response of human lymphoblastoid cells to activated medium Refer to individual Series
Project description:ChIP-seq was done on one lymphoblastoid cell lines for vehicle control, or 3-MC agonist treatment to identify AHR binding regions throughout the genome. We identified 17,688 common binding peaks between all ChIP treatments
Project description:To determine if induced p53 binding is associated with gene expression in genome-wide. We examined mRNA levels with the Affymetrix Human Exon 1.0 ST platform in human lymphoblastoid GM12878 cells treated with doxorubicin to activate p53. In response to various cellular stresses, the tumor suppressor gene p53 induces activation or repression of more than a thousand human genes. Selective binding and transactivation of a large potential pool of p53 response elements (REs) is believed to regulate the variation in stress response across stress types and between cell types. To elucidate how the human genome is targeted by p53 at the chromatin level, we mapped the genome-wide localization of p53 and H3K4me3 from Doxo-treated human lymphoblastoid cells, and examined the relationships among p53 occupancy, gene expression, H3K4me3, chromatin accessibility (DNase 1 Hypersensitivity, DHS), ENCODE chromatin states, RE sequence specificity and evolutionary conservation.
Project description:Transcriptional profiling of human lymphoblastoid TK6 cells comparing mock irradiated cells with cells exposed 24 hours previously to 1.67 Gy HZE (1 GeV/amu iron ions accelerated at the NASA Space Research Laboratory (NSRL) of Brookhaven National Laboratory) or 2.5 Gy 137Cs gamma rays. TK6 cells were mock irradiated or exposed to HZE or gamma-rays, and RNA was harvested 24 hours later. 3 biological replicates were independently grown and harvested during three different runs at the NSRL. One replicate per array.
