    Circadian disruption is linked to tumorigenesis, but the role of circadian genes in osteosarcoma remains unclear.

  • 2

    A five-gene prognostic signature related to circadian rhythms was established and validated for osteosarcoma.

  • 3

    SULT1A1 was identified as a critical gene for osteosarcoma cell proliferation and sensitivity to melatonin.

  • 4

    Knockdown of SULT1A1 significantly reduced osteosarcoma cell proliferation and enhanced melatonin's anti-tumor effects.

  • 5

    This study suggests a mechanism connecting circadian gene networks to tumor cell state plasticity in osteosarcoma.
