• Insights into BRCA1 and TP53 associated breast cancer development from integrated whole genome analysis of mouse model mammary tumors

  Germline mutations in BRCA1 are a leading cause of hereditary breast cancer. We generated Brca1;Trp53 double conditional knockout (CKO) and Trp53 single CKO mouse models, both with either one or two copies of Trp53 deleted by Cre. We used whole-genome sequencing and optical genome mapping to interrogate the genomes of the resulting mammary tumors. Our comprehensive genomic analyses show that the Brca1;Trp53-CKO tumors recapitulate major genomic features of the human BRCA1 breast samples indicative of conserved fundamental mutational processes. This study also provides new insights into the genetic mechanisms of tumor development with potential implications for the treatment of BRCA1 cancers.

• Elevated somatic mutation burdens in normal human cells due to defective DNA polymerases

  Mutation accumulation over time in normal somatic cells contributes to cancer development and is proposed as a cause of ageing. DNA polymerases POLE and POLD1 replicate DNA with high fidelity during normal cell divisions. However, in some cancers defective proofreading due to acquired mutations in the exonuclease domains of POLE or POLD1 causes markedly elevated somatic mutation burdens with distinctive mutational signatures. POLE and POLD1 exonuclease domain mutations also cause familial cancer predisposition when inherited through the germline. Here, we sequenced normal tissue DNA from individuals with germline POLE or POLD1 exonuclease domain mutations. Increased mutation burdens with characteristic mutational signatures were found to varying extents in all normal adult somatic cell types examined, during early embryogenesis and in sperm. Mutation burdens were further markedly elevated in neoplasms from these individuals. Thus human physiology is able to tolerate ubiquitously elevated mutation burdens. Indeed, with the exception of early onset cancer, individuals with germline POLE and POLD1 exonuclease domain mutations are not reported to show abnormal phenotypic features, including those of premature ageing. The results, therefore, do not support a simple model in which all features of ageing are attributable to widespread cell malfunction directly resulting from somatic mutation burdens accrued during life.

• Transrenal DNA Analysis

  The current sequencing dataset consists of 91 whole genome sequencing data files (Fastq files) of human cell-free DNA (cfDNA) obtained from plasma and urine samples. Specifically, we extracted 20 ucfDNA and 17 plasma DNA samples from healthy pregnant women, 11 ucfDNA samples from pregnant women with preeclampsia, 19 ucfDNA samples from healthy controls, and 24 ucfDNA samples from patients with proteinuria. These extracted cfDNA samples were then constructed into DNA libraries using the TruSeq Nano DNA Library Prep Kit (Illumina) and subsequently sequenced on the Nextseq2000 platform (Illumina).
