Discovery of Novel Antitumor Sulfonamides Targeting G1 Phase of the Cell Cycle
Takashi Owa,Hiroshi Yoshino,Tatsuo Okauchi,Kentaro Yoshimatsu,Yoichi Ozawa,Naoko Hata Sugi,Takeshi Nagasu,Nozomu Koyanagi,Kyosuke Kitoh +8 more
TL;DR: N-(3-chloro-7-indolyl)-1,4-benzenedisulfonamide (E7070) showed significant antitumor activity against HCT116 human colon carcinoma both in vitro (IC(50) 0.11 microg/mL in cell proliferation assay) and in vivo (not only growth suppression but also a marked reduction of tumor size in nude mice).
Journal ArticleDOI
Eribulin mesilate suppresses experimental metastasis of breast cancer cells by reversing phenotype from epithelial–mesenchymal transition (EMT) to mesenchymal–epithelial transition (MET) states
Taku Yoshida,Yoichi Ozawa,Takayuki Kimura,Yoshiaki Sato,Galina Kuznetsov,Shanqin Xu,Mai Uesugi,Sergei Agoulnik,Noel Taylor,Yasuhiro Funahashi,Junji Matsui +10 more
TL;DR: Eribulin exerted significant effects on EMT/MET-related pathway components in human breast cancer cells in vitro and in vivo, consistent with a phenotypic switch from mesenchymal to epithelial states, and corresponding to observed decreases in migration and invasiveness in vitro as well as experimental metastasis in vivo.
Journal ArticleDOI
Lenvatinib plus anti-PD-1 antibody combination treatment activates CD8+ T cells through reduction of tumor-associated macrophage and activation of the interferon pathway.
Yu Kato,Kimiyo Tabata,Takayuki Kimura,Ayako Yachie-Kinoshita,Yoichi Ozawa,Kazuhiko Yamada,Junichi Ito,Sho Tachino,Yusaku Hori,Masahiro Matsuki,Yukiko Matsuoka,Samik Ghosh,Hiroaki Kitano,Kenichi Nomoto,Junji Matsui,Yasuhiro Funahashi +15 more
TL;DR: It is shown that lenvatinib modulates cancer immunity in the tumor microenvironment by reducing TAMs and, when combined with PD-1 blockade, shows enhanced antitumor activity via the IFN signaling pathway.
Journal ArticleDOI
Eribulin mesylate reduces tumor microenvironment abnormality by vascular remodeling in preclinical human breast cancer models.
Yasuhiro Funahashi,Kiyoshi Okamoto,Yusuke Adachi,Taro Semba,Mai Uesugi,Yoichi Ozawa,Osamu Tohyama,Taisuke Uehara,Takayuki Kimura,Hideki Watanabe,Makoto Asano,Satoshi Kawano,Xavier Tizon,Paul J. McCracken,Junji Matsui,Ken Aoshima,Kenichi Nomoto,Yoshiya Oda +17 more
TL;DR: It is shown that eribulin induces remodeling of tumor vasculature through a novel antivascular activity in MX‐1 and MDA‐MB‐231 human breast cancer xenograft models, suggesting that Eribulin‐induced remodelling of abnormal tumor vasculation leads to a more functional microenvironment that may reduce the aggressiveness of tumors due to elimination of inner tumor hypoxia.
Journal ArticleDOI
Immunomodulatory activity of lenvatinib contributes to antitumor activity in the Hepa1-6 hepatocellular carcinoma model
Takayuki Kimura,Yu Kato,Yoichi Ozawa,Kotaro Kodama,Junichi Ito,Kenji Ichikawa,Kazuhiko Yamada,Yusaku Hori,Kimiyo Tabata,Kazuma Takase,Junji Matsui,Yasuhiro Funahashi,Kenichi Nomoto +12 more
TL;DR: Lenvatinib has immunomodulatory activity that contributes to the antitumor activity of lenvatinIB and enhances the antitUMor activity in combination treatment with anti‐PD‐1 antibody, and warrants further investigation against advanced HCC.
