    N-terminus of Drosophila melanogaster MSL1 is critical for dosage compensation

    Valentin Babosha, Natalia Klimenko ... Oksana Maksimenko
    N‑terminus of MSL1 protein, involved in dosage compensation in Drosophila, is required for the interaction with non-coding roX2 RNA and the assembly of the complex on the male X chromosome.

    Complex aneuploidy triggers autophagy and p53-mediated apoptosis and impairs the second lineage segregation in human preimplantation embryos

    Marius Regin, Yingnan Lei ... Claudia Spits
    Aneuploid human embryonic cells are eliminated by p53-mediated apoptosis in a gene dosage dependent manner.

    Reassessing the substrate specificities of the major Staphylococcus aureus peptidoglycan hydrolases lysostaphin and LytM

    Lina Antenucci, Salla Virtanen ... Perttu Permi
    Robust NMR approach allowed simultaneous detection of substrate cleavage site and real-time kinetics of hydrolysis for Staphylococcus aureus peptidoglycan hydrolases lysostaphin and LytM, and revealed D-alanyl-glycine activity for LytM.

    Linking the evolution of two prefrontal brain regions to social and foraging challenges in primates

    Sebastien Bouret, Emmanuel Paradis ... Cecile Garcia
    Across primates, volumes of specific brain regions relate to specific socio-ecological factors, bridging the gap between neuro-cognitive operations from laboratory studies and challenges primates face in their natural environment.

    Extreme positive epistasis for fitness in monosomic yeast strains

    Hanna Tutaj, Katarzyna Tomala ... Ryszard Korona
    Monosomy in yeast results in numerous gene dosage insufficiencies with potentially lethal collective effect, but strong positive epistasis rooted in the modular structure of cell metabolism cancels it.

    Patient-derived xenografts and single-cell sequencing identifies three subtypes of tumor-reactive lymphocytes in uveal melanoma metastases

    Joakim W Karlsson, Vasu R Sah ... Jonas A Nilsson
    Single-cell sequencing and functional analysis identify T cells that can be useful for marker selection and cell therapy in uveal melanoma, a disease largely unresponsive to conventional immune checkpoint therapies.

    Katanin, kinesin-13, and ataxin-2 inhibit premature interaction between maternal and paternal genomes in C. elegans zygotes

    Elizabeth A Beath, Cynthia Bailey ... Francis J McNally
    Limiting cytoplasmic streaming contributes to maintaining spatial separation of the sperm contents from the female meiotic spindle after fertilization.

    Thermal phenotypic plasticity of pre- and post-copulatory male harm buffers sexual conflict in wild Drosophila melanogaster

    Claudia Londoño-Nieto, Roberto García-Roa ... Pau Carazo
    Natural temperature variation across an optimal reproductive range for wild flies (Drosophila melanogaster) modulates the impact of sexual conflict on female fitness via asymmetric effects on pre- and post-copulatory male harm mechanisms.
