Outline of Research at the Start

がん悪液質は、体重減少・骨格筋萎縮・食思不振を主徴とする臨床症候群である。進行がん患者の約8割が、悪液質を発症し、世界では年間900万人近くのがん患者が悪液質を発症していると推定されている。現在、悪液質の本態は不明で、実効性のある早期診断方法や治療介入法が存在しない。本研究では、悪液質モデル動物および臨床検体を組み合わせ、総合的に解析して悪液質治療薬の開発基盤を構築する。

Outline of Final Research Achievements

Cancer cachexia is characterized by significant weight loss, reduced appetite, and muscle wasting. The underlying mechanisms of cancer cachexia are not yet fully understood, and there is currently no effective treatment. In studies involving mouse models of cancer cachexia, we observed that NAD (nicotinamide adenine dinucleotide) levels were reduced by about 50%, and the expression of CD38, an enzyme that degrades NAD, was significantly increased. Vitamin B cocktails containing NAD precursors did not prolong survival in the SEKI cancer cachexia mouse models. Administrating compound 78c, a CD38 inhibitor, increased their liver and skeletal muscle mass. Additionally, we observed a decrease in blood levels of tryptophan, a precursor for NAD, in both mice with cancer cachexia and patients with gastric cancer cachexia. These findings provide crucial insights into the metabolic disturbances associated with cancer cachexia and could guide the development of future therapies.

Academic Significance and Societal Importance of the Research Achievements

がん悪液質は、進行性の体重減少・骨格筋萎縮・食思不振を主徴とする複合的な代謝性症候群である。多くの進行がん患者が、悪液質を発症し、がん悪液質はがん患者の約20%にとって直接死因であるとされる。紀元前の文献にも、悪液質に関する記録が残されているが、現在に至るまで、悪液質の本態は不明である。がん悪液質の本態は依然として不明で、実効性のある早期診断方法や治療介入法の開発が望まれている。本研究成果はがん悪液質の代謝学的側面の解明に関して一定の貢献をすることが期待される。
