Project Period (FY) 2018-04-01 – 2021-03-31
Keywords悪性骨軟部腫瘍 / フェロトーシス / SHARPIN
Outline of Final Research Achievements

TCGA dataset of soft tissue sarcoma 265 cases showed that high SHARPIN expression is associated with poor prognosis. SHARPIN inhibition enhanced resistance against ferroptosis. Further investigation will be warranted to clarify the sensitivity of ferroptosis on sarcoma entities with high SHARPIN expression which is correlated with poor prognosis.

Academic Significance and Societal Importance of the Research Achievements

悪性骨軟部腫瘍(肉腫)は難治性希少がんであり有効な化学療法が少なく新たな治療薬の開発が強く望まれている。本研究にてSHARPINと予後不良との関連および鉄依存性細胞死フェロトーシスへの関与を解明できた。本研究を礎にして、今後肉腫における新規抗がん剤治療としてフェロトーシスの有効性を明らかにし肉腫患者の予後を改善させるため臨床応用を目指したい。
