    Ribosomal protein S27-like is a physiological regulator of p53 that suppresses genomic instability and tumorigenesis

    Xiufang Xiong, Yongchao Zhao ... Yi Sun
    The ribosomal protein, Rps27l, plays an oncogenic role by promoting p53 degradation via stabilizing the Mdm2-Mdm4 complex, but a tumor suppressor role by preventing the aneuploidy and loss of p53 heterozygosity.

    FXR1 regulates transcription and is required for growth of human cancer cells with TP53/FXR2 homozygous deletion

    Yichao Fan, Jiao Yue ... Bin Xiang
    Functional and mechanistic analyses of cancer cells containing homozygous deletion of TP53 and FXR2 reveal that inhibition of FXR1 blocks cell proliferation in a collateral lethality manner, opening an avenue to develop therapies targeting such cancers.

    MPI depletion enhances O-GlcNAcylation of p53 and suppresses the Warburg effect

    Nataly Shtraizent, Charles DeRossi ... Jaime Chu
    Mannose phosphate isomerase is a metabolic enzyme regulating cell survival in both embryonic and cancer cells.

    Endogenous p53 expression in human and mouse is not regulated by its 3′UTR

    Sibylle Mitschka, Christine Mayr
    The endogenous 3′UTR does not regulate TP53 mRNA or protein level and the 3′UTR is repressive when used alone in reporters, but addition of the coding region has a dominant repressive effect.

    Inactivation of the ATMIN/ATM pathway protects against glioblastoma formation

    Sophia M Blake, Stefan H Stricker ... Axel Behrens
    Deletion of the ATM cofactor ATMIN reduces PDGFRA expression and strongly suppresses tumorigenesis in a TP53-deficient mouse model of glioblastoma.

    SMC5/6 is required for replication fork stability and faithful chromosome segregation during neurogenesis

    Alisa Atkins, Michelle J Xu ... Philip W Jordan
    The structural maintenance of chromosomes complex, SMC5/6, is crucial for brain development and function as it ensures proficient DNA replication in neural progenitor cells prior to chromosome segregation.

    A requirement of Polo-like kinase 1 in murine embryonic myogenesis and adult muscle regeneration

    Zhihao Jia, Yaohui Nie ... Shihuan Kuang
    Inhibition of Polo-like kinase that has been shown to exhibit antitumor effect unexpectedly disrupts muscle stem cell function, leading to developmental and regenerative failures.

    Transglutaminase 2 contributes to a TP53-induced autophagy program to prevent oncogenic transformation

    Shi Yun Yeo, Yoko Itahana ... Koji Itahana
    Loss-of-function screening identified transglutaminase 2 (TGM2) as a putative tumor suppressor in the TP53 pathway and revealed that TGM2-mediated autophagy and CDKN1A-mediated cell cycle arrest are two critical barriers that prevent oncogenic transformation.

    MCMBP promotes the assembly of the MCM2–7 hetero-hexamer to ensure robust DNA replication in human cells

    Yuichiro Saito, Venny Santosa ... Masato T Kanemaki
    The MCM-binding protein (MCMBP) promotes the hexamer assembly of the replicative MCM2–7 helicase by interacting with the nascent MCM3 subunit, playing a key role in achieving high expression levels of the functional MCM2–7 helicase for maintaining genome integrity.
