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

    Shi Yun Yeo et al.
    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.

    Parallel CRISPR-Cas9 screens clarify impacts of p53 on screen performance

    Anne Ramsay Bowden et al.
    The protein p53 negatively impacts the ability of a CRISPR screen to discriminate between essential and non-essential genes, hence, p53 status should be considered in these screens.

    Prosurvival long noncoding RNA PINCR regulates a subset of p53 targets in human colorectal cancer cells by binding to Matrin 3

    Ritu Chaudhary et al.
    Functional and mechanistic analysis of p53-regulated lncRNA PINCR and its interacting RNA-binding protein Matrin 3 uncovers context-dependent regulation of specific p53 target genes during DNA damage.

    Inactivation of oncogenic cAMP-specific phosphodiesterase 4D by miR-139-5p in response to p53 activation

    Bo Cao et al.
    The tumor suppressor p53 prevents tumor cell growth by employing a small RNA called miR-139-5p to inhibit the activity of an tumorigenic protein, cAMP-specific phosphodiesterase 4D.

    Nerve growth factor receptor negates the tumor suppressor p53 as a feedback regulator

    Xiang Zhou et al.
    The nerve growth factor receptor (NGFR) protein regulates p53 via two negative feedback mechanisms, which are hijacked by cancer cells.

    Quality control in oocytes by p63 is based on a spring-loaded activation mechanism on the molecular and cellular level

    Daniel Coutandin et al.
    p63 uses an intricate network of domain-domain interactions to control its function in long-term quality maintenance of resting oocytes.

    Dissecting the DNA binding landscape and gene regulatory network of p63 and p53

    Konstantin Riege et al.
    A resource of p63-regulated genes, genomic loci bound by p63, p63 DNA recognition motifs, and potential co-factors is generated through a meta-analysis of high-throughput datasets.

    TP53 exon-6 truncating mutations produce separation of function isoforms with pro-tumorigenic functions

    Nitin H Shirole et al.
    Genetic and molecular analysis of TP53 exon-6 truncating mutations reveal that these mutations, contrary to current belief, promote tumorigenesis and point towards strategies for treating cancers driven by these prevalent mutations.

    Activation of PTHrP-cAMP-CREB1 signaling following p53 loss is essential for osteosarcoma initiation and maintenance

    Mannu K Walia et al.
    The loss of p53 in bone cells activates critical signaling pathways; these are also essential in bone cancer.

    Global analysis of p53-regulated transcription identifies its direct targets and unexpected regulatory mechanisms

    Mary Ann Allen et al.
    The first global analysis of the effects of the transcription factor p53 on RNA synthesis illuminates several novels aspects of the molecular mechanism of action of this potent tumor suppressor.
