Decoding Brain Somatic Mosaicism with New Single-Cell Copy Number Analysis Methods
Copy number variants (CNVs) represent a significant but understudied form of somatic variation in the human brain, with potential implications for neurodevelopment, aging and disease. While single-cell whole-genome sequencing (scWGS) enables genome-wide profiling at single-cell resolution, existing …

Decoding Copy Number Substructure and Evolution From Single Cell Genomics
… model of TNBC evolution is the Punctuated Copy Number Evolution (PCNE), in which tumors undergo a period of elevated genomic instability, acquiring complex genomic rearrangements within a short timeframe followed by clonal stasis. However, these observations rely on limited cell numbers and …

Genomic Evolution of Chemoresistance In Triple-Negative Breast Cancer Delineated By Single Cell Sequencing
… To investigate this question we applied single cell DNA and RNA sequencing methods and deep-exome sequencing to longitudinal time-point samples collected from a cohort of 20 TNBC patients. Deep-exome sequencing of the cohort at three time points revealed patterns of both clonal extinction …

A Pan-Cancer Single-Cell Analysis of Intratumoral Copy Number Diversity and Evolution
… is a hallmark of human cancers, with many copy number aberrations (CNAs) being associated with disease progression. Previous studies have revealed extensive inter-patient heterogeneity (IPH) in copy number profiles. However, the extent of intratumoral heterogeneity (ITH) and its …

Measuring ongoing chromosomal instability in single-cell DNA sequencing data
… – a computational tool to correctly estimate single-cell ploidy and replication status. Cancer cells often exhibit DNA copy number aberrations and can vary widely in their ploidy as a consequence. Correct estimation of the ploidy of single cell genomes is crucial for many aspects of downstream …

Probabilistic modelling of somatic alterations in bulk tissue and single cells using repeat DNA
… class of structural alterations are somatic copy number alterations (SCNAs). SCNAs have been shown to be major drivers of oncogenesis and are associated with prognosis and response to therapies. Current sequencing and array-based methods that are used to infer SCNAs are cost-prohibitive for …
