    Live-cell imaging reveals enhancer-dependent Sox2 transcription in the absence of enhancer proximity

    Jeffrey M Alexander, Juan Guan ... Orion D Weiner
    Sox2 transcription is not correlated with spatial proximity of its essential regulatory enhancer in embryonic stem cells, suggesting gene transcription is not limited to periods of direct enhancer-promoter contact.

    Bayesian inference of kinetic schemes for ion channels by Kalman filtering

    Jan L Münch, Fabian Paul ... Klaus Benndorf
    For analyzing time-dependent patch-clamp or patch-clamp fluorometry data of ion channels in terms of Markovian models, the superiority of Bayesian filtering with respect to traditional deterministic approaches is demonstrated enabling more reliable quantification of the parameters.

    NMNAT promotes glioma growth through regulating post-translational modifications of P53 to inhibit apoptosis

    Jiaqi Liu, Xianzun Tao ... R Grace Zhai
    NMNAT is genetically required for glioma development and promotes glioma growth by allowing a higher tolerance to DNA damage and inhibiting DNA damage-p53-caspase-3 apoptosis signaling pathway by enhancing NAD+-dependent posttranslational modifications (PTMs) poly(ADP-ribosyl)ation (PARylation) and deacetylation of p53.

    An experimentally validated network of nine haematopoietic transcription factors reveals mechanisms of cell state stability

    Judith Schütte, Huange Wang ... Berthold Göttgens
    A computer model built on insights gained from comprehensive experimental analysis reveals mechanisms of blood stem cell regulation.

    Human VMPFC encodes early signatures of confidence in perceptual decisions

    Sabina Gherman, Marios G. Philiastides
    Simultaneous EEG-fMRI reveals neural representations of decision confidence unfolding prior to explicit perceptual choices, in a region of the ventromedial prefrontal cortex typically linked to reward processing and value-based decisions.

    A partially nested cortical hierarchy of neural states underlies event segmentation in the human brain

    Linda Geerligs, Dora Gözükara ... Umut Güçlü
    The ongoing stream of information that comes in through our senses is segmented into distinct neural states at each level of the cortical hierarchy, which underpins our experience of distinct events.

    Lipolysis of bone marrow adipocytes is required to fuel bone and the marrow niche during energy deficits

    Ziru Li, Emily Bowers ... Ormond A MacDougald
    Bone marrow adipocyte lipolysis is required for maintaining bone mass under conditions of energy deficiency and is necessary for myelopoiesis following caloric restriction and irradiation.

    Short-range interactions between fibrocytes and CD8+ T cells in COPD bronchial inflammatory response

    Edmée Eyraud, Elise Maurat ... Isabelle Dupin
    Intercellular interactions between fibrocytes and CD8+ T lymphocytes promote inflammation through a pathophysiological positive feedback loop in bronchi of patients with chronic obstructive pulmonary disease (COPD).

    One-shot analysis of translated mammalian lncRNAs with AHARIBO

    Luca Minati, Claudia Firrito ... Massimiliano Clamer
    Detection of translated lncRNAs through selective isolation of active ribosomes, ribosome-associated RNAs and corresponding de novo synthesised peptides.

    Top-down machine learning approach for high-throughput single-molecule analysis

    David S White, Marcel P Goldschen-Ohm ... Baron Chanda
    A new analysis algorithm (DISC) enables accurate analysis of data from high-throughput single-molecule paradigms and reveals a non-cooperative binding mechanism of cyclic nucleotide-binding domains from HCN ion channels.
