Outline of Research at the Start

がん細胞を取り巻く微小環境は酸性化しているが、なぜ通常細胞にとって害悪な酸性環境下でがん細胞が増殖し続けられるか、よくわかっていない。申請者はがん細胞の酸性適応機構の一端としてリソソーム内のプロトンが細胞外に放出されるlysosomal exocytosisの重要性を見つけており、本研究でこの現象の酸性環境適応におけるがん種、生物種を超えた普遍的な役割を示すことを目指す。

Outline of Final Research Achievements

We found that increased PRL3 expression under acidic conditions is important for the induction of lysosomal exocytosis, and that the overexpression of PRL3 in malignant cancer cells is part of the physiological adaptation to the acidic environment. In addition, from chemical screening using compounds with known targets we also revealed the importance of signaling pathways that are activated in malignant cancer tissues.

Academic Significance and Societal Importance of the Research Achievements

本研究によりlysosomal exocytosisの普遍的重要性を明らかにでき、酸性環境適応の理解が大きく進んだと考えられる。今後さらに多様な生物種においても同様の仕組みで酸性環境適応が行われているかなど、研究を展開させてゆくことで地球上の生命に共通した、さらに「普遍的」な重要性についても明らかにしてゆけると期待される。
