Outline of Final Research Achievements

The objective of this study is to determine whether Fatty acid-binding protein (FABP4) secreted from adipocytes or a macrophage in endometrial cancer maintained the tumor micro-environment.
We first confirmed the expression of FABP4 in endometrial cancer cell, and FABP4 transfered into cytoplasm exogeniously. we confirmed relation obesity to invasion and lymph node metastasis. Furthermore, We measured in computed tomography and visceral fat / subcutaneous fat ratio before cancer therapy to investigate the relaion histological type or prognosis to fat.We confirmed the patient with high ratio of fat/subcutaneous fat ratio was endometrial cancer of G3, serous, clear cell carcinoma.It was suggested to the cancer micro-environment of endometrial cancer may relate with visceral fat cell and subcutaneous fat.

Academic Significance and Societal Importance of the Research Achievements

メタボリック症候群における子宮体がん発症のメカニズムは未知な部分が多い。そこで我々はメタボリック症候群の発症に関連している新規アディポカインであるFABP4に着目し、FABP4が子宮体がん細胞内に存在し、FABP4が高い内臓脂肪が多い患者ではより悪性度の高いがん組織型であることがわかった。また内臓脂肪だけでなく皮下脂肪にもがん発症に関連することが示唆された。今後さらにこのメカニズムを解明することにより、メタボリック症候群による子宮体がん発症予防につながることが期待される。
