Tumor necrosis factor-like weak inducer of apoptosis (TWEAK) and its receptor fibroblast growth factor-inducible immediate-early response protein 14 (Fn14) have been detected in several human tumors, and demonstrated to regulate multiple cellular responses, including proliferation, survival, migration, apoptosis and differentiation, suggesting roles in cancer. The objective of this study was to clarify the role of TWEAK/Fn14 in the development of human endometrial cancer. We found that TWEAK gene...
