Our group aims to understand the role of epigenetic changes in cancer initiation and progression and decipher the link between genetic and epigenetic modifications. We obtained insights about the role of genetic and epigenetic changes in specific cancer types: neuroblastoma, Ewing sarcoma and erythroleukemia. We also developed pioneer methodology to analyze high-throughput data from DNA sequencing and ChIP-seq experiments generated for cancer samples.

  • HMCan-diff: a method to detect changes in histone modifications in cells with different genetic characteristics. H. Ashoor, C. Louis-Brennetot, I. Janoueix-Lerosey, V.B. Bajic, and V. Boeva. Nucleic Acids Research. 2017. doi: 10.1093/nar/gkw1319, Link. HMCan-diff is the first computational method for detection of differential ChIP-seq or ATAC-seq signal in cancer cells. The main improvement of HMCan-diff over methods developed for normal cells is its ability to correct the signal for the GC-content and copy number bias.
  • Jarid2 is implicated in the initial Xist-induced targeting of PRC2 to the inactive X chromosome. S.T. da Rocha, V. Boeva, M. Escamilla-Del-Arenal, K. Ancelin, C. Granier, N. Reis Matias, S. Sanulli, J. Chow, E. Schulz, C. Picard, S. Kaneko, K. Helin, D. Reinberg, A. F. Stewart, A. Wutz, R. Margueron and E. Heard. Molecular Cell, 2014, 53 (2): 301-316. PMID: 24462204. Here we show that the Jarid2 protein works as a mediator between binding of the long noncoding RNA Xist coating the X chromosome being inactivated and the Polycomb Repressive Complex 2, which disposes repressive histone mark H3K27me3.
  • HMCan: a method for detecting chromatin modifications in cancer samples using ChIP-seq data. H. Ashoor, A. Hérault, A. Kamoun, F. Radvanyi, V.B. Bajic, E. Barillot and V. Boeva. Bioinformatics, 2013, 29 (23): 2979-2986. PMID: 24021381. Here we propose the first method to detect regions of enrichment in histone modifications in cancer ChIP-seq data. We show that existing methods, such as MACS or SICER, suffer from significant copy number bias.
  • Control-FREEC: a tool for assessing copy number and allelic content using next generation sequencing data. V. Boeva, T. Popova, K. Bleakley, P. Chiche, I. Janoueix-Lerosey, O. Delattre and E. Barillot. Bioinformatics, 2012, 28(3):423-5. PMID: 22155870. In this paper, we present one of the first methods to assess copy number and genotype information in whole genome and exome sequencing data. When applied to cancer data, our method allows correcting for contamination by normal cells and variable sample ploidy.
