    RAD50 deletion in intestinal epithelial cells exacerbates ulcerative colitis and increases the risk of colitis-associated cancer in murine models.

  • 2

    Loss of RAD50 leads to increased DNA double-strand breaks and heightened inflammatory responses in colitis and cancer models.

  • 3

    RAD50 interacts with STAT3, inhibiting its phosphorylation and disrupting the IL-6-JAK1/2-STAT3 signaling loop.

  • 4

    Pharmacological inhibition of STAT3 alleviates colitis symptoms in RAD50-deficient mice, highlighting RAD50's protective role.

  • 5

    Enhancing RAD50 levels in colon tissues may offer a therapeutic strategy for patients suffering from ulcerative colitis and colitis-associated cancer.
