The cytidine deaminase AID hypermutates immunoglobulin genes but can also target oncogenes, leading to tumorigenesis. The extent of AID's promiscuity and its predilection for immunoglobulin genes are unknown. We report here that AID interacted broadly with promoter-proximal sequences associated with stalled polymerases and chromatin-activating marks. In contrast, genomic occupancy of replication protein A (RPA), an AID cofactor, was restricted to immunoglobulin genes. The recruitment of RPA to t ...[more]

A mouse model of endemic Burkitt translocations reveals the long-range boundaries of Ig-mediated oncogene deregulation

Project description:Igh/Myc translocations underlie both sporadic Burkitt lymphoma (BL) and the endemic clinical form affecting African children infected with malaria. However, while sporadic translocations decapitate Myc from 5' proximal regulatory elements, most endemic events occur hundreds of kilobases away from Myc. The origin of these rearrangements and how they deregulate oncogenes at such distances remain unclear. Here we recapitulate endemic BL-like translocations in plasmacytomas from uracil N-glycosylase (UNG) deficient mice. We demonstrate that in these animals, rare endemic-like translocations arise from non-targeted DNA breaks at Myc loci. Deep-sequencing analyses revealed that the deregulated 3' Igh enhancer alpha physically interacts with and remodels 0.45Mb of translocated chromatin. The results thus explain the long-range deregulation of oncogenes in human and mouse B cell tumors. ChIP-Seq, 4C, and 1 RNASeq samples used to characterize mouse plasmacytoma cell lines and in vitro activated mouse B cells. Biological replicates are present for many of the samples.

RPA accumulation during class switch recombination represents 5'-3' DNA end resection during the S-G2/M phase of the cell cycle

Project description:AID promotes chromosomal translocations by inducing DNA double-strand breaks (DSBs) at immunoglobulin (Ig) genes and oncogenes in G1. RPA is a ssDNA-binding protein that associates with resected DSBs in the S phase and facilitates the assembly of factors involved in homologous repair (HR) such as Rad51. Notably, RPA deposition also marks sites of AID-mediated damage, but its role in Ig gene recombination remains unclear. Here we demonstrate that RPA associates asymmetrically with resected ssDNA in response to lesions created by AID, RAG, or other nucleases. Small amounts of RPA are deposited at AID targets in G1 in an ATM-dependent manner. In contrast, recruitment in S-G2/M is extensive, ATM-independent, and associated with Rad51 accumulation. RPA in S-G2/M increases in NHEJ-deficient lymphocytes, where there is more extensive DNA-end resection. Thus, most RPA recruitment during CSR represents salvage of un-repaired breaks by homology-based pathways during the S-G2/M phases of the cell cycle. Chip-Seq of RPA from mouse activated B cells (n = 40), mouse thymocytes (n = 6), and MEFs (n = 1). Different genotypes and/or inhibitors were used.

Genome wide localization of Activation induced cytidine deaminase (AID), Spt5, and RNA Polymerase II (PolII) in mouse

Project description:Activation induced cytidine deaminase (AID) initiates antibody gene diversification by creating U:G mismatches. However, AID is not specific for antibody genes. Off-target lesions can activate oncogenes or cause chromosome translocations. Despite its importance in these key transactions little is known about how AID finds its target sites. To examine AID regulation we performed an shRNA screen. We found that Spt5, a factor associated with paused RNA polymerase II (Pol II) and single stranded DNA (ssDNA), is required for class switch recombination (CSR). Spt5 interacts with AID, it is required for the association of AID and Pol II, and for AID recruitment to switch regions. ChIP-seq experiments reveal that Spt5 co-localizes with AID and stalled Pol II. Further, Spt5 accumulation at sites of Pol II pausing is predictive of AID-induced mutation. Our data suggest that Spt5 acts as an adaptor, which brings AID to Pol II on target DNA. PolII, AID, and Spt5 were immunoprecipitated from in vitro activated B cells. For Spt5 and AID, two different antibodies were used in separate, biological replicates

High-throughput pyrosequencing of endogenous small RNAs in O. Europaea

Project description:Small RNAs of 20 to 25 nucleotides in length maintain genome integrity and control gene expression in a multitude of developmental and physiological processes. Despite RNA silencing has been primarily studied in model plants, the advent of high-throughput sequencing technologies has enabled profiling of the small RNA component of more than 40 plant species. Here, use deep sequencing and molecular methods to report the first inventory of small RNAs in olive (Olea europaea). Small RNAs of 24 nts dominate the small RNA transcriptome and atypically accumulate to levels never seen in other plant species, suggesting an active role of heterochromatin silencing in the maintenance and integrity of its large genome. By contrast, small RNAs of 20 to 22 nts were poorly represented in the population at levels lower than those found in most plant species tested. A total of 14 known miRNA families were identified in two libraries prepared from growing and dormant lateral buds. We found that some known miRNAs showed tissue- and/or developmental-specific expression. Also, seven novel, olive-specific miRNA candidates were found in our sequenced set of which 1 were supported by their star strands. Potential precursors for these miRNA candidates with intramolecular folding capacities were found in the olive EST database. Target mRNAs of conserved miRNAs and new olive-specific miRNA were computationally predicted among the olive EST collection and experimentally validated through endonucleolytic cleavage assays. Two samples analyzed: growing (juvenile) and dormant (adult) lateral buds from the progeny of a genetic cross between the Picual and Arbequina olive varieties

RNA polymerase V targets transcriptional silencing components to promoters of protein-coding genes

Project description:Transcriptional gene silencing controls transposons and other repetitive elements through RNA-directed DNA methylation (RdDM) and heterochromatin formation. A key component of the Arabidopsis RdDM pathway is ARGONAUTE4 (AGO4), which associates with sizs to mediate DNA methylation. Here, we show that AGO4 preferentially targets transposable elements embedded within promoters of protein-coding genes. This pattern of AGO4 binding cannot be simply explained by the sequences of AGO4-bound siRNAs; instead, AGO4 binding to specific gene promoters is also mediated by long non-coding RNAs (lncRNAs) produced by RNA polymerase V. lncRNA-mediated AGO4 binding to gene promoters directs asymmetric DNA methylation to these genomic regions and is involved in regulating the expression of targeted genes. Finally, AGO4 binding overlaps sites of DNA methylation affected by the biotic stress response. Based on these findings, we propose that the targets of AGO4-directed RdDM are regulatory units responsible for controlling gene expression under specific environmental conditions.

Genome-wide targets of conserved histone chaperone Asf1 in budding yeast

Project description:Asf1, through its histone chaperone activity, helps chromatin closing/opening during DNA replication, repair, recombination and transcription. Despite extensive research on Asf1-mediated physiological functions, a genome-wide localization map is lacking, limiting our knowledge of chromosomal features targeted by Asf1. We present a high-resolution genome-wide map of Asf1, localizing at essentially all pol III-transcribed genes, highly active pol II-transcribed genes and heterochromatic features. Pol III-transcribed genes are negatively regulated by Asf1, whereas pol II genes are regulated indirectly by Asf1-dependent H3K56 acetylation. Interestingly, Asf1 localization along yeast chromosomes shows nearly identical distribution to that of the condensin complex, predicting a functional overlap in chromosome architecture and genome organization. ChIP-seq analysis of Asf1 targets using a yeast strain that expresses an 18-Myc tag fused to the C-terminus of ASF1. Two biological replicates and one mock/control were performed. The Illumina GAII was used. ChIP-seq reads are aligned to the budding yeast sacCer3 (2011) assembly.
