Outline of Final Research Achievements

The energy metabolic activity of mitochondrial electron transport chains could be measured in transplanted tumor tissue from mice and spontaneous tumors from dogs using the Seahorse XFp Analyzer. In the future, the prognostic factors such as malignancy and differentiation as well as the relationship with response to therapy can be investigated by improving the sampling method and accumulating the number of clinical cases.

Academic Significance and Societal Importance of the Research Achievements

本研究は多種多様な腫瘍のイヌから腫瘍組織をサンプリングし、ミトコンドリア電子伝達系活性を評価することで、自然発生の腫瘍のエネルギー代謝を解明する糸口となり、エネルギー代謝を標的とした新たな抗ガン治療として発展する可能性が高い。また、今後、症例数を蓄積することで腫瘍のエネルギー代謝が腫瘍の予後因子に関連することが証明できれば、腫瘍のエネルギー代謝を測定することがより一般的になり、後続研究へ応用される可能性が非常に高い。
