Outline of Final Research Achievements

We have developed endocrine-resistant breast cancer models using estrogen-sensitive MCF-7 cells. They were cultivated under an estrogen-deprived condition or exposure to an antiestrogen for over six months. Long-term estrogen-deprived (LTED) and fulvestrant (FUL)-resistant cells were established. An mRNA expression microarray revealed, 1) LTED cells showed an up-regulation of estrogen receptor (ER) signaling pathway, hypersensitivity to estrogen and an increase in cancer stem cell population. 2) FUL-resistant cells showed a down-regulation of ER signaling pathway, estrogen-insensitivity, up-regulation of hedgehog signaling pathway and increased expression levels of human epidermal growth factor receptor (HER) 1 and HER2. Increased expression levels of CXCR4 and HER4 were commonly observed in the LTED and FUL-resistant cells. We have been involved in exploratory studies on clarifying if these agents may overcome endocrine-resistance in the LTED and FUL-resistant breast cancer cells.

Academic Significance and Societal Importance of the Research Achievements

乳癌の内分泌療法耐性の原因としては、細胞内外の増殖関連シグナルが活性化が重要である。本研究においてもHERファミリーのHER1, HER2, HER4の発現増加が確認された。E枯渇下及びフルベストラント曝露下におけるHER4の発現増加は、我々の知る限り初めての報告となる。HER4のシグナルを抑制するneratinibが内分泌療法耐性の克服に役立つ可能性がある。CXCR4は、癌細胞の浸潤や転移に関わる因子として注目されているが、癌幹細胞の生存や増殖にも関与している。CXCR4の働きを特異的に阻害するCXCR4阻害薬プレリキサホルはすでに臨床導入されており、内分泌療法耐性乳癌への応用も可能である。
