A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Oncogene-induced senescence (OIS) is a potent barrier for the transformation of pre-cancerous cells. The molecular pathways involved in the execution of OIS are still incompletely understood, but they include chronic DNA damage signaling and post-translational modifications of key factors. Here, we show that OIS-associated transcriptional downregulation of deubiquitinating enzyme USP1 triggers and maintains a DNA damage checkpoint response with atypical DNA lesions that is dependent on functional FANCD2-FI-ATR-CHK1-p53-CDKN1A signaling. We find that a reduced USP1 level causes aberrant aggregation of its target FANCD2 concomitant with replication stress, accumulation, and colocalization of γ-H2Ax and p53-binding protein 1 (53BP1) in large and unusual sparse DNA damage foci and an increased number of polyploid cells and cells arrested in G2/M, as well as a sensitization of senescence-bypassing cells to DNA interstrand crosslinking-mediated cell death. Our study identifies USP1 as a key senescence regulator controlling genomic integrity and a promising target for anti-cancer therapy.
