    Stochastic modelling, Bayesian inference, and new in vivo measurements elucidate the debated mtDNA bottleneck mechanism

    Iain G Johnston et al.
    New modelling, statistics, and experiments show that cellular populations of mitochondrial DNA (mtDNA) evolve during development according to solvable stochastic dynamics involving binomial partitioning and random turnover, facilitating a predictive and quantitative theory of the mtDNA bottleneck.

    Distinct modes of SMAD2 chromatin binding and remodeling shape the transcriptional response to NODAL/Activin signaling

    Davide M Coda et al.
    NODAL/Activin-induced SMAD2 binding directly drives remodeling of both open and closed chromatin and does not directly correlate with temporal patterns of gene expression upon prolonged signaling.

    Dynamic regulation of transcription factors by nucleosome remodeling

    Ming Li et al.
    Single molecule DNA unzipping reveals a novel model for the regulation of transcription factors and nucleosome positioning via nucleosome remodeling in yeast.

    Phenotype-based cell-specific metabolic modeling reveals metabolic liabilities of cancer

    Keren Yizhak et al.
    Genome-scale metabolic modeling of individual cancer cells and healthy human cells identifies specific and selective metabolic vulnerabilities.

    ATP-dependent chromatin assembly is functionally distinct from chromatin remodeling

    Sharon E Torigoe et al.
    The Chd1 motor protein performs two functionally distinct ATP-dependent activities, nucleosome assembly and chromatin remodeling, to generate periodic arrays of nucleosomes.

    Ten simple rules for the computational modeling of behavioral data

    Robert C Wilson, Anne GE Collins
    Computational modeling of cognitive and neuroscience data is an insightful and powerful tool, but has many potential pitfalls that can be avoided by following simple guidelines.

    Single-cell modeling of routine clinical blood tests reveals transient dynamics of human response to blood loss

    Anwesha Chaudhury et al.
    Unsteady state modeling of blood cell populations reveals that blood loss triggers a cellular clearance delay and a cellular production increase, and modeling provides earlier detection and individualized patient characterization.

    Modelling primaquine-induced haemolysis in G6PD deficiency

    James Watson et al.
    In silico modelling of all available data shows that a twenty-day ascending-dose primaquine regimen could be safe to administer to G6PD deficient patients for the radical cure of vivax malaria.

    Mathematical modeling of the West Africa Ebola epidemic

    Jean-Paul Chretien et al.
    A review of mathematical models applied to the West Africa Ebola epidemic suggests ways to improve the use of mathematical modeling in responding to public health emergencies.

    Nucleosome breathing and remodeling constrain CRISPR-Cas9 function

    R Stefan Isaac et al.
    The inhibitory influence of nucleosomes on CRISPR-Cas9 is mitigated by nucleosomal DNA breathing and chromatin remodeling.
