    Sexual dimorphism in obesity is governed by RELMα regulation of adipose macrophages and eosinophils

    Jiang Li, Rebecca E Ruggiero-Ruff ... Meera G Nair
    The small macrophage-secreted protein RELMα is a sex-specific protein that protects against diet-induced obesity through regulating the macrophage–eosinophil innate immune axis in the adipose tissue.

    The Drosophila ZAD zinc finger protein Kipferl guides Rhino to piRNA clusters

    Lisa Baumgartner, Dominik Handler ... Julius Brennecke
    Kipferl, a ZAD zinc finger protein from Drosophila, determines the chromatin binding specificity of the heterochromatin protein variant Rhino, defining piRNA clusters and preventing Rhino sequestration by selfish Satellite repeats.

    A near atomic structure of the active human apoptosome

    Tat Cheung Cheng, Chuan Hong ... Christopher W Akey
    A cryo-electron microscopy model of the active human apoptosome illuminates how this "wheel of death" binds the protease procaspase-9 to initiate programmed cell death.

    The conserved genetic program of male germ cells uncovers ancient regulators of human spermatogenesis

    Rion Brattig-Correia, Joana M Almeida ... Paulo Navarro-Costa
    An interdisciplinary research platform reveals that the transcriptional identity of metazoan male germ cells is built around a small network of deeply conserved gene interactions with an overarching functional impact.

    Species-specific chromatin landscape determines how transposable elements shape genome evolution

    Yuheng Huang, Harsh Shukla, Yuh Chwen G Lee
    The ultimate driver for the substantial between-species difference in the success of transposable elements, the widely distributed genetic parasite, may lie in the overall chromatin environment.

    Decoding the activated stem cell phenotype of the neonatally maturing pituitary

    Emma Laporte, Florian Hermans ... Hugo Vankelecom
    The neonatally maturing pituitary harbors an activated stem cell compartment and shows prominent regenerative capacity, as revealed by single-cell transcriptomic profiling and in vitro (organoid) and in vivo (mouse) exploration.
