Gupta and Robert A. Somer Abstract High-throughput genomic technologies have revealed a full mutational landscape of tumors could help reconstruct remarkably complex portrait of intratumor heterogeneity in their phylogenetic trees and trace the subclonal origins of cancer and have shown that tumors evolve through a reiterative therapeutic resistance, relapsed disease, and distant metastases, process of genetic diversification and clonal selection. This the major causes of cancer-related mortality. Real-time assess- discovery has challenged the classical paradigm of clonal ment of the tumor subclonal architecture, however, remains dominance and brought attention to subclonal tumor cell limited by the high rate of errors produced by most genome- populations that contribute to the cancer phenotype. Dynamic wide sequencing methods as well as the practical difficulties evolutionary models may explain how these populations grow associated with serial tumor genotyping in patients. This review within the ecosystem of tissues, including linear, branching, focuses on novel approaches to mitigate these challenges using neutral, and punctuated patterns. Recent evidence in breast bulk tumor, liquid biopsies, single-cell analysis, and deep cancer favors branching and punctuated evolution driven by sequencing techniques. The origins of intratumor heterogene- genome instability as well as nongenetic sources of heteroge- ity and the clinical, diagnostic, and therapeutic consequences neity, such as epigenetic variation, hierarchal tumor cell orga- in breast cancer are also explored.

We investigated the impact of a telomere-driven crisis on 23 the structural integrity of the genome by undertaking whole genome sequence analyses of 24 clonal populations of cells that had escaped crisis.

Discrepant Outcomes in Two Brazilian
Moreira et al. Journal of Medical Case Reports 2013, 7:284 JOURNAL OF MEDICAL http://www.jmedicalcasereports.com/content/7/1/284 CASE REPORTS CASE REPORT Open Access Discrepant outcomes in two Brazilian patients with Bloom syndrome and Wilms’ tumor: two case reports Marilia Borges Moreira1,2,3*, Caio Robledo DC Quaio1, Aline Cristina Zandoná-Teixeira1, Gil Monteiro Novo-Filho1, Evelin Aline Zanardo1, Leslie Domenici Kulikowski2 and Chong Ae Kim1 Abstract Introduction: Bloom syndrome is a rare, autosomal recessive, chromosomal instability disorder caused by mutations in the BLM gene that increase the risk of developing neoplasias, particularly lymphomas and leukemias, at an early age. Case presentation: Case 1 was a 10-year-old Brazilian girl, the third child of a non-consanguineous non-Jewish family, who was born at 36 weeks of gestation and presented with severe intrauterine growth restriction. She had Bloom syndrome and was diagnosed with a unilateral Wilms’ tumor at the age of 3.5 years. She responded well to oncological treatment and has remained disease-free for the last 17 years. Case 2 was a 2-year-old Brazilian girl born to non-Jewish first-degree cousins. Her gestation was marked by intrauterine growth restriction. She had Bloom syndrome; a unilateral stage II Wilms’ tumor was diagnosed at the age of 4 years after the evaluation of a sudden onset abdominal mass. Surgical removal, neoadjuvant chemotherapy and radiotherapy were not sufficient to control the neoplasia. The tumor recurred after 8 months and she died from clinical complications. Conclusion: Our study reports the importance of rapid diagnostics and clinical follow-up of these patients. -

Chromothripsis occurs commonly in various human cancers and is thought to be associated with increased malignancy and carcinogenesis. However, the causes and consequences of chromothripsis remain unclear. -

Genome-wide Purification of Extrachromosomal Circular DNA from Eukaryotic Cells. J. Vis. Exp. (110), e54239, doi:10.3791/54239 (2016). Abstract Extrachromosomal circular DNAs (eccDNAs) are common genetic elements in Saccharomyces cerevisiae and are reported in other eukaryotes as well. EccDNAs contribute to genetic variation among somatic cells in multicellular organisms and to evolution of unicellular eukaryotes. Sensitive methods for detecting eccDNA are needed to clarify how these elements affect genome stability and how environmental and biological factors induce their formation in eukaryotic cells. This video presents a sensitive eccDNA-purification method called Circle-Seq. The method encompasses column purification of circular DNA, removal of remaining linear chromosomal DNA, rolling-circle amplification of eccDNA, deep sequencing, and mapping. Extensive exonuclease treatment was required for sufficient linear chromosomal DNA degradation. The rolling-circle amplification step by φ29 polymerase enriched for circular DNA over linear DNA. -
Double Minute Chromosomes in Glioblastoma Multiforme Are Revealed by Precise Reconstruction of Oncogenic Amplicons
Published OnlineFirst August 12, 2013; DOI: 10.1158/0008-5472.CAN-13-0186 Cancer Tumor and Stem Cell Biology Research Double Minute Chromosomes in Glioblastoma Multiforme Are Revealed by Precise Reconstruction of Oncogenic Amplicons J. Zachary Sanborn1,2,Sofie R. Salama2,3, Mia Grifford2, Cameron W. Brennan4, Tom Mikkelsen6, Suresh Jhanwar5, Sol Katzman2, Lynda Chin7, and David Haussler2,3 Abstract DNA sequencing offers a powerful tool in oncology based on the precise definition of structural rearrange- ments and copy number in tumor genomes. Here, we describe the development of methods to compute copy number and detect structural variants to locally reconstruct highly rearranged regions of the tumor genome with high precision from standard, short-read, paired-end sequencing datasets. We find that circular assemblies are the most parsimonious explanation for a set of highly amplified tumor regions in a subset of glioblastoma multiforme samples sequenced by The Cancer Genome Atlas (TCGA) consortium, revealing evidence for double minute chromosomes in these tumors. Further, we find that some samples harbor multiple circular amplicons and, in some cases, further rearrangements occurred after the initial amplicon-generating event. Fluorescence in situ hybridization analysis offered an initial confirmation of the presence of double minute chromosomes. Gene content in these assemblies helps identify likely driver oncogenes for these amplicons. RNA-seq data available for one double minute chromosome offered additional support for our local tumor genome assemblies, and identified the birth of a novel exon made possible through rearranged sequences present in the double minute chromosomes. Our method was also useful for analysis of a larger set of glioblastoma multiforme tumors for which exome sequencing data are available, finding evidence for oncogenic double minute chromosomes in more than 20% of clinical specimens examined, a frequency consistent with previous estimates. -
