The ability of p53 to regulate transcription is crucial for tumor suppression and implies that inherited polymorphisms in functional p53-binding sites could influence cancer. Here, we identify a polymorphic p53 responsive element and demonstrate its influence on cancer risk using genome-wide data sets of cancer susceptibility loci, genetic variation, p53 occupancy, and p53-binding sites. We uncover a single-nucleotide polymorphism (SNP) in a functional p53-binding site and establish its influenc ...[more]

Identification of Novel NRF2-Regulated Genes by ChIPSeq

Project description:Cellular oxidative and electrophilic stress triggers a protective response in mammals regulated by NRF2 (nuclear factor (erythroid-derived) 2-like; NFE2L2) binding to DNA-regulatory sequences near stress responsive genes. Studies using Nrf2-deficient mice suggest that hundreds of genes may be regulated by NRF2. To identify human NRF2-regulated genes, we conducted ChIP-sequencing experiments in lymphoid cells treated with the dietary isothiocyanate, sulforaphane (SFN) and carried out follow-up biological experiments on candidates. We found 242 high-confidence, NRF2-bound genomic regions and 96% of these regions contained NRF2-regulatory sequence motifs. The majority of binding sites were near potential novel members of the NRF2 pathway. Validation of selected candidate genes using parallel ChIP techniques and in NRF2-silenced cell lines indicated that the expression of about two thirds of the candidates are likely to be directly NRF2-dependent including retinoid X receptor alpha (RXRA). NRF2 regulation of RXRAhas implications for response to retinoid treatments and adipogenesis. In mouse 3T3-L1 cells SFN treatment affected Rxra expression early in adipogenesis and knockdown of Nrf2 delayed Rxra expression, both leading to impaired adipogenesis.

Genome-wide analysis of p53 transcriptional programs in B cells upon exposure to genotoxic stress in vivo [ChIP-Seq]

Project description:The tumor suppressor p53 is a transcription factor that coordinates the cellular response to DNA damage. Here we provide an integrated analysis of p53 genomic occupancy and p53-dependent gene regulation in the splenic B and non-B cell compartments of mice exposed to whole-body ionizing radiation, providing insight into general principles of p53 activity in vivo. In unstressed conditions, p53 bound few genomic targets; induction of p53 by ionizing radiation increased the number of p53 bound sites, leading to highly overlapping profiles in the different cell types. Comparison of these profiles with chromatin features in unstressed B cells revealed that, upon activation, p53 localized at active promoters, distal enhancers, and a smaller set of unmarked distal regions. At promoters, recognition of the canonical p53 motif as well as binding strength were associated with p53-dependent transcriptional activation, but not repression, indicating that the latter was most likely indirect. p53-activated targets constituted the core of a cell type-independent response, superimposed onto a cell type-specific program. Core response genes included most of the known p53-regulated genes, as well as many new ones. Our data represent a unique characterization of the p53-regulated response to ionizing radiation in vivo.

Genome-wide target discovery of transcripton factor E2F4 by ChIP-seq

Project description:The transcription factor E2F4 is a member of the E2F family of regulators which has critical roles in cell cycle control and differentiation. In order to fully understand the physiological roles of E2F4 and the regulatory networks it mediates, and to reveal its relationships with other members of the E2F family, it is essential to comprehensively identify E2F4 target sites throughout the genome. Here, we investigated genome-wide E2F4 targets in human lymphoblastoid cells using the recently developed unbiased target discovery technique of ChIP sequencing. We sequecned E2F4 ChIP and corresponding Input

Gene expression in human lymphoblastoid cell-line GM12878 in response to doxorubicin treatment

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. Human lymphoblastoid (GM 12878) cells at a density of 900,000 cells/ml were prepared in triplicate for each time point and treated with 0.5 µM doxorubicin (Calbiochem) for 4, 18 hr or no treatment (at 0 time). Total RNA will be extracted from each culture (9 RNA samples) using the Qiagen RNeasy kit with DNase digestion. RNA was quantified using RiboGreen (Invitrogen), check for quality by OD and Bioanalyzer and stored at -80°C. Expression analysis was conducted at at NIEHS Microarray Core using Affymetrix Human Exon 1.0 ST arrays following the Affymetrix hybridization protocols. Exon expression data were analyzed through Affymetrix Expression Console using gene-level RMA summarization and sketch-quantile normalization methods.

Structural Assessment of the Full-Length Tumor Suppressor Protein p53 by Mass Spectrometry-Guided Computational Modeling

Project description:The tetrameric tumor suppressor p53 represents a great challenge for 3D structural analysis due to its high degree of intrinsic disorder (ca. 40%). We developed and applied an integrative structural biology approach combining complementary techniques of structural mass spectrometry (MS), namely cross-linking mass spectrometry (XL-MS), protein footprinting, and hydrogen/deuterium exchange mass spectrometry (HDX-MS), with advanced protein structure prediction approaches to gain insights into the disordered C-terminal region of p53. Additionally, we evaluate possible differences in p53 regarding solvent accessibility and topology upon DNA binding. Our quantitative XL-MS and lysine labeling data show no major conformational differences in p53 between DNA-bound and DNA-free states. Integration of experimental data generate p53 models for p53’s intrinsically disordered regions (IDRs) that reflect substantial compaction of the molecule. Our models provide the most detailed description of the relationship between p53’s folded regions and IDRs that is available to date. The synergies between complementary structural MS techniques and computational modeling as pursued in our integrative approach is envisioned to serve as general strategy for studying intrinsically disordered proteins (IDPs) and IDRs.

Phosphorylation of p53 Serine 46 contributes to target gene selectivity of p53 (ChIP-seq)

Project description:The tumor suppressor p53 plays a crucial role in cellular growth control inducing a plethora of cellular response pathways. The molecular mechanisms that discriminate between the distinct p53-responses towards different stress treatments have remained largely elusive. Here, we have analyzed the p53-regulated pathways induced by two chemotherapeutical treatments, Actinomycin D inducing growth arrest and Etoposide resulting in apoptosis. We found that the genome-wide p53-binding patterns are almost identical upon both treatments notwithstanding transcriptional differences that we observed in genome-wide transcriptome analysis. To assess the role of post-translational modifications in target gene choice and activation we investigated the extent of phosphorylation of Serine 46 of p53 bound to DNA (p53-pS46), a modification that has been linked to apoptosis-pathways, and the extent of phosphorylation of Serine 15 (p53-pS15), a general p53-activation mark. Interestingly, the overall extent of S46 phosphorylation of p53 bound to DNA is considerably higher in cells directed towards apoptosis while the degree of phosphorylation at S15 of DNA bound p53 remains highly similar upon both treatments. Moreover, our data suggest that, following different chemotherapeutical treatments, the extent of chromatin-associated p53 phosphorylated at S46 but not at pS15 is higher on certain apoptosis related target genes, including the BAX and PUMA genes. These data provide evidence that cell fate decisions are not made primarily on the level of general p53 DNA-binding, but possibly through post-translational modifications of chromatin bound p53. ChIP-seq profiles of p53, p53phosphorylated at Serine 15 (p53-pS15) and p53 phosphorylated at Serine 46 (p53-pS46) in U2OS cells treated with either Actinomycin D or Etoposide.
