    Inositol pyrophosphate dynamics reveals control of the yeast phosphate starvation program through 1,5-IP8 and the SPX domain of Pho81

    Valentin Chabert, Geun-Don Kim ... Andreas Mayer
    Analysis of inositol pyrophosphate dynamics upon inorganic phosphate (Pi) starvation identifies 1,5-IP8 as the inositol pyrophosphate isomer signaling Pi sufficiency to the SPX domain of Pho81 that controls the transcriptional Pi starvation program.

    Single molecule analysis of CENP-A chromatin by high-speed atomic force microscopy

    Daniël P Melters, Keir C Neuman ... Yamini Dalal
    A novel analytical workflow to quantitatively track motions of thousands of nucleosomes within chromatin fibers by high-speed atomic force microscopy.

    Selective loss of CD107a TIGIT+ memory HIV-1-specific CD8+ T cells in PLWH over a decade of ART

    Oscar Blanch-Lombarte, Dan Ouchi ... Julia G Prado
    PLWH over a decade of ART showed a significant reshaping of the function and expression of inhibitory receptors across the CD8+ T cell landscape, ultimately leading to a decrease of CD107a TIGIT HIV-1-specific CD8+ T cells recovered by TIGIT blockade.

    Lmx1a is a master regulator of the cortical hem

    Igor Y Iskusnykh, Nikolai Fattakhov ... Victor V Chizhikov
    LIM-homeodomain transcription factor Lmx1a co-regulates multiple developmental processes in the cortical hem, a major signaling center necessary for hippocampus formation in the mammalian brain.

    Epigenetic signature of human immune aging in the GESTALT study

    Roshni Roy, Pei-Lun Kuo ... Luigi Ferrucci
    Identification of human DNA sites differentially methylated with aging across six different primary immune cells suggests that the sensing of hypoxia drives the epigenetic clock.

    Resting-state fMRI signals contain spectral signatures of local hemodynamic response timing

    Sydney M Bailes, Daniel EP Gomez ... Laura D Lewis
    The frequency content of resting-state fMRI signals contains information that can characterize and predict local variations in hemodynamic response timing which enhances the temporal precision of fMRI.

    BATF relieves hepatic steatosis by inhibiting PD1 and promoting energy metabolism

    Zhiwang Zhang, Qichao Liao ... Lei Zhou
    Gene function studies confirmed that the BATF-PD1 axis and BATF-IL27 axis are regulatory factor for lipid accumulation in hepatocytes and adipocytes.

    Effects of smoking on genome-wide DNA methylation profiles: A study of discordant and concordant monozygotic twin pairs

    Jenny van Dongen, Gonneke Willemsen ... Michael C Neale
    Analysis of data from monozygotic twins reveals that DNA methylation level in human blood cells is reactive to cigarette smoking.

    Biosensor-integrated transposon mutagenesis reveals rv0158 as a coordinator of redox homeostasis in Mycobacterium tuberculosis

    Somnath Shee, Reshma T Veetil ... Amit Singh
    Genome-scale integration of transposon mutagenesis with a redox biosensor identified a hypothetical transcription factor- Rv0158 required to calibrate the growth, cytoplasmic redox potential, and respiration of Mycobacterium tuberculosis in response to metabolic switching from glucose to fatty acids.

    A generic binding pocket for small molecule IKs activators at the extracellular inter-subunit interface of KCNQ1 and KCNE1 channel complexes

    Magnus Chan, Harutyun Sahakyan ... David Fedida
    Characterization of an extra-membrane site in IKs formed by KCNQ1 S1, Pore and S6 domains and the near extracellular region of KCNE1, which forms a binding pocket for channel activators.
