| Outline of Final Research Achievements |
Our studies revealed that the expression of sST2, a soluble receptor for IL-33, in human and mouse colorectal cancer cells suppress sporadic metastasis via modulating inflammatory tumormicroenvironments. Importantly, the administration of recombinant sST2 showed antitumor and antimetastatic effects in human or mouse colon tumor-bearing mice. Our results also indicated that ST2 expression levels in tumor tissues may be an effective prognostic biomarker in colon cancer. Collectively, our studies demonstrate the potential for developing novel ST2-based therapeutic and diagnostic strategies for colorectal cancer.
