    HLJ1 amplifies endotoxin-induced sepsis severity by promoting IL-12 heterodimerization in macrophages

    Wei-Jia Luo, Sung-Liang Yu ... Kang-Yi Su
    Single-cell RNA sequencing reveals HLJ1 as a novel immunomodulator for multicellular pathway of macrophages and NK cells, contributing to organ injury and sepsis death through amplified IL-12/IFN-γ axis.

    A functional screen of RNA binding proteins identifies genes that promote or limit the accumulation of CD138+ plasma cells

    David J Turner, Alexander Saveliev ... Martin Turner
    A genetic screening approach identifies RNA binding proteins that enhance or inhibit the accumulation of CD138+ plasma cells in vitro, and chimeric mouse models demonstrate that YTHDF2 promotes the accumulation of antibody secreting cells in vivo.

    Stella modulates transcriptional and endogenous retrovirus programs during maternal-to-zygotic transition

    Yun Huang, Jong Kyoung Kim ... M Azim Surani
    Soon after fertilisation, a critical portion of the embryonic genome is switched on through the actions of maternally inherited Stella, in part through controlling the activation of transposable elements.

    DePARylation is critical for S phase progression and cell survival

    Litong Nie, Chao Wang ... Junjie Chen
    DePARylation is essential for cell survival and thus poly(ADP-ribose) glycohydrolase (PARG) expression correlates with cytotoxicity induced by PARG inhibition, which will benefit the development of PARG inhibitors for cancer treatment.

    HAT cofactor TRRAP modulates microtubule dynamics via SP1 signaling to prevent neurodegeneration

    Alicia Tapias, David Lázaro ... Zhao-Qi Wang
    The Trrap-HAT-Sp1 axis operates a conserved transcriptional program to control proper microtubule dynamics in brain homeostasis and prevents neurodegeneration.

    The transcription factors TFE3 and TFEB amplify p53 dependent transcriptional programs in response to DNA damage

    Owen A Brady, Eutteum Jeong ... Rosa Puertollano
    Disruption of TFEB and TFE3 results in diminished p53 signaling capacity and altered cell cycle regulation under genotoxic stress conditions.
