The role of KISS1/KISS1R system in tumor growth and invasion of differentiated thyroid cancer.

Abstract

Increased expression of KISS1 is possibly acquired to prevent further tumor invasiveness and formation of local or distant metastasis. It appears that malignant cells in DTC express increased levels of KISS1 as the tumor invades extrathyroidal tissues. Decreased expression of KISS1R seems to attenuate signaling of the KISS1/KISS1R system, possibly leading to tumor growth.
