Abstract

Integrin β3 (ITGB3) is linked to critical processes in tumor progression, including invasion and metastasis.

  • Dysregulated ITGB3 expression activates pathways associated with cell movement and growth.
  • Key malignant processes influenced by ITGB3 include angiogenesis and immune evasion.
  • ITGB3 is identified as a valuable biomarker for early cancer diagnosis and prognosis.
  • Therapeutic strategies targeting ITGB3 include small-molecule inhibitors and monoclonal antibodies.
  • Traditional Chinese Medicine formulations may provide unique regulatory benefits for targeting ITGB3.
