    Measures of genetic diversification in somatic tissues at bulk and single-cell resolution

    Marius E Moeller, Nathaniel V Mon Père ... Weini Huang
    Single-cell and bulk sequencing data are combined through theoretical modeling to reveal the number of tissue-specific stem cells, mutation, and proliferation rates under sampling.

    Host-pathogen genetic interactions underlie tuberculosis susceptibility in genetically diverse mice

    Clare M Smith, Richard E Baker ... Christopher M Sassetti
    A novel dual genome approach that combines genetically diverse mice and a library of bacterial mutants to define the genome-wide host pathogen interactions that drive distinct outcomes to tuberculosis.

    Resolving rates of mutation in the brain using single-neuron genomics

    Gilad D Evrony, Eunjung Lee ... Christopher A Walsh
    The reanalysis of data from a recent study that claimed retrotransposon mutations are ubiquitous in the human brain outlines a general framework for the design and analysis of single-cell genomics studies.

    Computational Biology: Capturing the unpredictability of stem cells

    Arda Durmaz, Valeria Visconte
    A new mathematical model that can be applied to both single-cell and bulk DNA sequencing data sheds light on the processes governing population dynamics in stem cells.

    Increased inflammatory signature in myeloid cells of non-small cell lung cancer patients with high clonal hematopoiesis burden

    Hyungtai Sim, Hyun Jung Park ... Murim Choi
    In metastatic NSCLC patients, CHIP showed minimal impact on immunotherapy response but was more prevalent and associated with inflammatory pathways in myeloid cells, particularly in lung squamous cell carcinoma.

    Most cancers carry a substantial deleterious load due to Hill-Robertson interference

    Susanne Tilk, Svyatoslav Tkachenko ... Christopher D McFarland
    The absence of negative selection observed in most cancer genomes can be explained by the intrinsic genome-wide linkage in somatic evolution and creates a substantial proteotoxic load.

    Genetic profiling of protein burden and nuclear export overload

    Reiko Kintaka, Koji Makanae ... Hisao Moriya
    A comprehensive analysis of yeast mutants has provided clues to understanding the physiological conditions caused by protein overexpression.

    Testis single-cell RNA-seq reveals the dynamics of de novo gene transcription and germline mutational bias in Drosophila

    Evan Witt, Sigi Benjamin ... Li Zhao
    Single-cell RNA-sequencing and germline substitutions provide novel insights into how testis is a hotspot for evolutionary innovation of genes, expression, and mutation at the single-cell level.

    The multi-tissue landscape of somatic mtDNA mutations indicates tissue-specific accumulation and removal in aging

    Monica Sanchez-Contreras, Mariya T Sweetwyne ... Scott R Kennedy
    The accumulation of somatic mutations during aging is not uniform across tissue types and, in addition, shows significant variability in the source of mutation that can be modified by small molecule interventions.
