    Predictive nonlinear modeling of malignant myelopoiesis and tyrosine kinase inhibitor therapy

    Jonathan Rodriguez, Abdon Iniguez ... Richard A Van Etten
    A physiological mathematical model of chronic myeloid leukemia, validated by experiments in transgenic mice and clinical data, identifies mechanisms underlying the response to tyrosine kinase inhibitor therapy, predicts biomarkers of primary resistance, and suggests new strategies to improve treatment outcomes.

    Allosteric conformational ensembles have unlimited capacity for integrating information

    John W Biddle, Rosa Martinez-Corral ... Jeremy Gunawardena
    The effective higher-order binding cooperativities arising from an ensemble of dynamically interchanging conformations are identified and shown to fully describe integration of binding information at thermodynamic equilibrium.

    Distinct representation of cue-outcome association by D1 and D2 neurons in the ventral striatum’s olfactory tubercle

    Nuné Martiros, Vikrant Kapoor ... Venkatesh N Murthy
    Real-time imaging of neural activity in behaving mice reveals that the two canonical types of neurons in the olfactory tubercle carry distinct information about learned odor cues, with D1 neurons representing stimulus valence and D2 neurons mainly representing stimulus identity.

    Mating activates neuroendocrine pathways signaling hunger in Drosophila females

    Meghan Laturney, Gabriella R Sterne, Kristin Scott
    Postmated increases in sucrose consumption in Drosophila melanogaster females is executed by a female specific circuit that alters neuroendocrine centers to promote hunger.

    De novo apical domain formation inside the Drosophila adult midgut epithelium

    Jia Chen, Daniel St Johnston
    Drosophila enteroblasts form septate junctions, an apical domain and an internal lumen inside the midgut epithelium before they reach the gut surface, thereby maintaining the intestinal barrier as they integrate.

    Determining cellular CTCF and cohesin abundances to constrain 3D genome models

    Claudia Cattoglio, Iryna Pustova ... Anders S Hansen
    Absolute quantification of CTCF and cohesin reveals quantitative constraints on 3D genome organization and illuminates the molecular architecture of the cohesin complex.

    Delta-dependent Notch activation closes the early neuroblast temporal program to promote lineage progression and neurogenesis termination in Drosophila

    Chhavi Sood, Md Ausrafuggaman Nahid ... Sarah E Siegrist
    Notch signaling regulates the neuroblast intrinsic temporal program to determine when neuroblasts terminate their cell divisions during development.

    Recovering mixtures of fast-diffusing states from short single-particle trajectories

    Alec Heckert, Liza Dahal ... Xavier Darzacq
    Tracking proteins in live cells is challenging due to technical limitations and biological complexity, but approaches based in Bayesian nonparametrics stand a decent chance at recovering a target protein's dynamic profile from noisy data.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat, Dagny Von Ahrens ... Amit Verma
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.
