Outline of Final Research Achievements

Triple negative breast cancer (TNBC), that defined by lacking of ER and PR expression and HER2 amplification, shows aggressive phenotype, although no specific therapy has been established, except for hereditary breast cancer. Therefore, a novel therapeutic strategy for TNBC is strongly desired. We thus investigated the anticancer effects of resveratrol (RSV), one of the grape-derived polyphenols, on TNBC cells. RSV induced epithelial-like morphological changes, suppressed invasion capacity, and increased cytotoxicity of Bcl2 inhibitor (ABT263) in MDA-MB-231 and BT549-Luc cells. It also increased expression and histone acetylation of CDH1 and CDKN1A tumor suppressive genes. Moreover, transfection of CDKN1A siRNA reduced ABT263-induced apoptosis in RSV-treated MDA-MB-231 cells. In conclusion, this study demonstrated a potential of RSV as a novel therapeutic and preventive agent for TNBC through increased cytotoxicity of ABT263 and inhibition of metastatic capacity of TNBC cells.

Academic Significance and Societal Importance of the Research Achievements

TNBCは悪性度が高く予後不良であることから、新規治療・予防法の開発が望まれている。本研究では、複数のTNBC細胞を用い、エピゲノム制御作用があるRSVの治療・予防薬としての有用性とその分子機構を示すことができた。食品成分であるRSVと他の薬剤との併用効果や、RSV単剤での転移能抑制作用が解明されたことは、新規エピゲノム治療薬として食品成分の可能性を示すという学術的意義に加え、特異的治療法が確立していない疾患に対する新規治療戦略としての社会的意義が大きいと考えられる。
