| Outline of Final Research Achievements |
The pathophysiological role of glucagon-like peptide-1 receptor (GLP-1R) in endometrial cancer has not been fully elucidated. Here, we investigated the effects of the GLP-1R agonist liraglutide in endometrial cancer cells and examined the association between GLP-1R expression and clinicopathological characteristics in endometrial cancer patients. Liraglutide dose dependently suppressed the cellular growth of Ishikawa endometrial cancer cells and the effect was turned out to be the induction of autophagy and subsequent cell death. Immunohistochemical analysis revealed that GLP-1R expression was associated with positive estrogen and progesterone receptor status, and higher GLP-1R expression was significantly correlated with better progression-free survival. The use of liraglutide to target autophagy in endometrial cancer cells may be a novel potential treatment for endometrial cancer, and higher GLP-1R expression may be associated with better prognosis in endometrial cancer patients.
