Outline of Final Research Achievements

This study revealed the intracellular target of azithromycin (AZM) for autophagy inhibition, and clarified one of the mechanisms how AZM inhibited autophagy. Additionally, we compared the autophagy inhibitory effect with other autophagy inhibitors, HCQ and Bafilomycin, and showed in which point AZM disrupted the autophagy. Particularly, unlike HCQ, we showed that AZM did not induce HIF-1a which is an important gene to sustain and promote cancer stem cell ability. Moreover, we also showed that AZM inhibited autophagy in transplanted tumors by oral administration, and suppressed tumor growth with xenograft mice model. These data show that AZM can be a good candidate for cancer therapy.

Academic Significance and Societal Importance of the Research Achievements

近年、がんにおけるオートファジーの様々な役割が明らかとなり、オートファジー阻害薬ががん治療の候補の1つに挙げられているが、実際に臨床で用いることのできるオートファジー阻害薬は1つしか無く、また、副作用が存在することもあり、臨床で用いることのできる新しいオートファジー阻害薬の開発は選択肢を増やす上でも非常に有用であり、望まれていることである。AZMは抗生物質として長年臨床の場で用いられた薬剤であり、また、本研究で明らかとなったAZMのオートファジー阻害効果の詳細は、AZMをオートファジー阻害薬として臨床応用する上での重要な意義を持つと考える。
