Mouse blood gene expression after administration of 137 Cesium

ABSTRACT: In the current study, we investigated the gene expression response of blood cells of mice that were injected with variable amounts of 137Cs We isolated total RNA from peripheral blood from mice with 0 (control), 158, 191, 215 and 259 uCi cesium source amount on days 2, 3, 5, 7 and 14 days after injection. Using Agilent Mouse Whole Genome microarrays, we identified x genes that were significantly differentially expressed across the 14-day time course of this study. We identified common biological functions affected that persisted across the 14-day study.

Impaired transcriptional profile in the hippocampus following loss of Kdm5a

Project description:KDM5A encodes a histone lysine demethylase that removes methyl groups from lysine 4 of histone H3, resulting in repression of target genes. In order to identify KDM5A targets, we profiled transcripts from hippocampi of WT and Kdm5a -/- mice. Loss of KDM5A resulted in dysregulation of 450 genes (FDR-corrected P ≤0.05 and log2 fold change ≥|0.3|), of which 191 genes were upregulated and 259 genes were downregulated.

Gene expression in blood of mice with internal exposure to Cs-137

Project description:Cesium-137 is a radionuclide of concern in fallout from reactor accidents or nuclear detonations. When ingested or inhaled, it can expose the entire body for an extended period of time, potentially contributing to serious health consequences ranging from acute radiation syndrome to increased cancer risks. In order to identify changes in gene expression that may be informative for detecting such exposure, and to begin examining the molecular responses involved, we have profiled global gene expression in mice injected with 137CsCl. We extracted RNA from the blood of control or 137CsCl-injected mice at 2, 3, 5, 20 or 30 days after exposure. Gene expression was measured using Agilent Whole Mouse Genome Microarrays, and the data was analyzed using BRB-ArrayTools. Three-month old male C57Bl/6 mice were injected intraperitoneally with 8.0 M-BM-1 0.3 MBq 137CsCl solution in a volume of 50 M-NM-<L, or left as controls. Groups of treated and control mice were sacrificed at intervals during the first 2-30 days after exposure, and total blood was collected using cardiac puncture. RNA was extracted from the blood, globin-transcript reduced, and subjected to whole genome expression microarray analysis.

Gamma irradiation does not induce detectable changes in DNA methylation in exposed human cells

Project description:Ionizing radiation, released during accidents at nuclear power plants or after atomic bomb explosions, is a potentially serious health threat for the exposed human population. This type of high-energy radiation causes DNA damage including single- and double-strand breaks and induces chromosomal rearrangements and mutations, but it is not known if ionizing radiation directly induces changes in the epigenome of irradiated cells. We treated normal human fibroblasts and normal human bronchial epithelial cells with different doses of gamma-radiation emitted from a cesium 137 (137Cs) radiation source. After a recovery period, we analyzed global DNA methylation patterns in the irradiated and control cells using the methylated-CpG island recovery assay (MIRA) method in combination with high-resolution microarrays. Bioinformatics analysis revealed only a small number of potential methylation changes with low fold-difference ratios in the irradiated cells. These minor methylation differences seen on the microarrays could not be verified by COBRA (combined bisulfite restriction analysis) or bisulfite sequencing of selected target loci. Our study shows that acute gamma-radiation treatment of two types of human cells had no appreciable effect on DNA cytosine methylation patterns in exposed cells.

Transcription profiling of human human prostate adenocarcinoma cells following irradiation to a dose of 10 Sv from a Cesium-137 gamma source

Project description:The experiment was a time course experiment on LNCaP C4-2 human prostate adenocarcinoma cells following irradiation to a dose of 10 Sv from a Cesium-137 gamma source. Total RNA was extracted from cells at 1, 2, 4, 6, 8, 12, 16, 20 and 24 hours after irradiation. The untreated control sample, labeled 0, was collected concurrently with the cells extracted at 24 hr. After extraction, the samples were processed and hybridized to the Affymetrix (Santa Clara, CA, www.affymetrix.com) HG-U95Av2 chip, and then washed, stained and scanned according to Affymetrix's protocols contained in the GeneChip(R) Expression Analysis Manual. Transcript abundance data from the scans was processed initially with Affymetrix' Microarray Suite 5(R), then by Silicon Genetics' (Redwood City, CA, www.silicongenetics.com) GeneSpring(R).

Pyrimidine Triones as Potential Activators of p53 Mutants

Project description:p53 is a crucial tumor suppressor in vertebrates that is frequently mutated in human cancers. Most mutations are missense mutations that render p53 inactive in suppressing tumor initiation and progression. Developing small molecule drugs to convert mutant p53 into an active, wild-type-like conformation is a significant focus for personalized cancer therapy. Prior research indicates that reactivating p53 suppresses cancer cell proliferation and tumor growth in animal models. Early clinical evidence with a compound selectively targeting p53 mutants with substitutions of tyrosine 220 suggests potential therapeutic benefits of reactivating p53 in patients. This study identifies and examines the UCI-1001 compound series as a potential corrector for several p53 mutations. The findings indicate that UCI-1001 treatment in p53 mutant cancer cell lines inhibits growth and reinstates wild-type p53 activities, including DNA binding, target gene activation, and induction of cell death. Cellular thermal shift assays, conformation-specific immunofluorescence staining, and differential scanning fluorometry suggest that UCI-1001 interacts with and alters the conformation of mutant p53 in cancer cells. These initial results identify pyrimidine trione derivatives of the UCI-1001 series as candidates for p53 corrector drug development.
