Project description:To generate the double-strand break (DSB) hotspot map in maize, we used a chromatin immunoprecipitation (ChIP) approach, in which chromatin from flowers containing zygotene meiocytes was enriched in fragments associated with RAD51.
Project description:In depth analysis of double strand break signaling was performed using mouse Pre-B cells and Human HCT116 cells. Our analysis included the induction of double strand breaks with ionizing radiation with the addition of ATM and DNA-PKcs inhibitors, alone and in combination.
Project description:CGH of stage 13 amplifying follicle cells to measure changes in replication fork progression in double-strand break repair mutants Comparative genomic hybridization was performed to compare amplification gradients of stage 13 follicle cells from several double-strand break repair mutants to wild type (OrR) gradients. Two-three replicates were done for each genotype.
Project description:In the bacterium Escherichia coli, RecG directs DNA synthesis during the repair of DNA double-strand breaks by homologous recombination. Examination of RecA binding during double-strand break repair in Escherichia coli in the presence and absence of RecG protein
Project description:We used ChIP-seq to assess where p53 binds in the human genome and how that binding changes during the DNA double-strand break response. In particular, we considered the 1-Mb-wide window centered on the MYC locus. Contrary to previous reports, we found no evidence of p53 binding at the MYC promoter. Rather, we identified three locations downstream of MYC at which p53 was bound; binding at each of these regions increased during the DNA double-strand break response.
Project description:In the bacterium Escherichia coli, RecBCD coordinates repair of two ends at a DNA double-strand break, preventing aberrant chromosome amplification
Project description:Here, we correlated and compared two different steps of the Double-Strand Break Repair pathway: RecA loading and Holliday junction formation
