The basal breast cancer subtype is enriched for triple-negative (TNBC) and displays consistent large chromosomal deletions. Here, we characterize evolution maintenance of chromosome 4p (chr4p) loss in cancer. Analysis Cancer Genome Atlas data shows recurrent deletion chr4p Phylogenetic analysis a panel 23 primary tumor/patient-derived xenograft cancers reveals early deletion. Mechanistically show that associated with enhanced proliferation. Gene function studies identify an unknown gene, C4orf19, within chr4p, which suppresses proliferation when overexpressed—a member the PDCD10-GCKIII kinase module name PGCKA1. Genome-wide pooled overexpression screens using barcoded library human open reading frames regions, including suppress overexpressed context-dependent manner, implicating network interactions. Together, these results shed light on emergence complex aneuploid karyotypes involving adaptive landscapes shaping genomes.

Intra-tumor heterogeneity (ITH) is a mechanism of therapeutic resistance and therefore an important clinical challenge. However, the extent, origin, drivers ITH across cancer types are poorly understood. To address this, we extensively characterize whole-genome sequences 2,658 samples spanning 38 types. Nearly all informative (95.1%) contain evidence distinct subclonal expansions with frequent branching relationships between subclones. We observe positive selection driver mutations most identify type-specific patterns gene mutations, fusions, structural variants, copy number alterations as well dynamic changes in mutational processes expansions. Our results underline importance its tumor evolution provide pan-cancer resource comprehensively annotated events from sequencing data.

Abstract Cancer is a leading cause of death worldwide and, despite new targeted therapies and immunotherapies, many patients with advanced-stage- or high-risk cancers still die, owing to metastatic disease. Adoptive T-cell therapy, involving the autologous allogeneic transplant tumour-infiltrating lymphocytes genetically modified T cells expressing novel receptors chimeric antigen receptors, has shown promise in treatment cancer patients, durable responses some cases, cure. Technological advances genomics, computational biology, immunology cell manufacturing have brought aspiration individualised for closer reality.

Identifying the origin of cancer Many cancers are classified on basis organ or tissue from which they originated. However, identifying specific cells and conditions that precede tumorigenesis can help us understand better treat resulting disease.

Abstract Richter transformation (RT) is a paradigmatic evolution of chronic lymphocytic leukemia (CLL) into very aggressive large B cell lymphoma conferring dismal prognosis. The mechanisms driving RT remain largely unknown. We characterized the whole genome, epigenome and transcriptome, combined with single-cell DNA/RNA-sequencing analyses functional experiments, 19 cases CLL developing RT. Studying 54 longitudinal samples covering up to years disease course, we uncovered minute subclones carrying genomic, immunogenetic transcriptomic features cells already at diagnosis, which were dormant for before transformation. also identified new driver alterations, discovered mutational signature (SBS-RT), recognized an oxidative phosphorylation (OXPHOS) high –B receptor (BCR) low -signaling transcriptional axis in showed that OXPHOS inhibition reduces proliferation cells. These findings demonstrate early seeding advanced stages cancer uncover potential therapeutic targets
