Purpose: Caveolin-1 is a membrane protein highly expressed in many tumors and plays an important role in tumor progression and metastasis. This review describes the structure of the Caveolin-1 protein and its pre-clinical and clinical significance, demonstrating that Caveolin-1 is a novel biomarker for radioresistance which has the promising potential to improve the clinical outcome of cancer patients undergoing radiation treatment.

Summary: Targeted radiation therapy has shown immense benefits for cancer treatment. However, one of the major challenges for effective clinical outcome of radiation therapy for cancer patients is the development of radioresistance during radiation treatment. As a consequence, radiation therapy becomes a less effective modality for successful clinical outcome. Furthermore, a radioresistant tumor has the ability to repair its genome, and therefore becomes more aggressive and …
