Outline of Final Research Achievements |
Although cancer treatment is no longer limited to poor prognosis, partly due to the advent of molecular-targeted drugs, anticancer drugs can cause various organ complications. Cardiovascular disease is an important factor affecting the long-term prognosis of cancer patients. Secondly, the decline in physical function has a significant impact on daily life and prognosis, and skeletal muscle loss is an important cause. It is suggested that cardiac dysfunction and skeletal muscle damage caused by anticancer drugs interact, and establishing a therapy is expected to improve the prognosis of cancer patients. The research plan was based on the assumption that the reduction of alternative autophagy is involved in the molecular mechanism of doxorubicin-induced cardiac and skeletal muscle dysfunction.

Academic Significance and Societal Importance of the Research Achievements |
抗癌剤による心機能障害と骨格筋障害は、相互に影響していることが示唆され、治療法を確立することは、癌患者の予後改善につながることが期待されます。ドキソルビシンによる心筋障害および骨格筋障害の分子機序に関与する機序として、オートファジーの低下が影響することが示唆された。
