Junichiro Matsuda,Osamu Suzuki,Akihiro Oshima,Yoshie Yamamoto,Akira Noguchi,Kazuhiro Takimoto,Masayuki Itoh,Yuji Matsuzaki,Yosuke Yasuda,Seiichiro Ogawa,Yuko Sakata,Eiji Nanba,Katsumi Higaki,Yoshimi Ogawa,Lika Tominaga,Kousaku Ohno,Hiroyuki Iwasaki,Hiroshi Watanabe,Roscoe O. Brady,Yoshiyuki Suzuki +19 more
TL;DR: A galactose derivative synthesized for chemical chaperone therapy of a human neurogenetic disease, β-galactosidosis, resulted in significant enhancement of the enzyme activity in the brain and other tissues and a marked decrease of intracellular substrate storage.
Journal ArticleDOI
Chemical chaperone therapy: clinical effect in murine GM1-gangliosidosis
Yoshiyuki Suzuki,Satoshi Ichinomiya,Mieko Kurosawa,Masato Ohkubo,Hiroshi Watanabe,Hiroyuki Iwasaki,Junichiro Matsuda,Yoko Noguchi,Kazuhiro Takimoto,Masayuki Itoh,Miho Tabe,Masami Iida,Takatoshi Kubo,Seiichiro Ogawa,Eiji Nanba,Katsumi Higaki,Kousaku Ohno,Roscoe O. Brady +17 more
TL;DR: Oral administration of a chaperone compound N‐octyl‐4‐epi‐β‐valienamine to GM1‐gangliosidosis model mice was delivered rapidly to the brain, increased β‐galactosidase activity, decreased ganglioside GM1, and prevented neurological deterioration within a few months.
Journal ArticleDOI
Fibroblast screening for chaperone therapy in β-galactosidosis
Hiroyuki Iwasaki,Hiroshi Watanabe,Masami Iida,Seiichiro Ogawa,Miho Tabe,Katsumi Higaki,Eiji Nanba,Yoshiyuki Suzuki +7 more
TL;DR: Screening of β-galactosidase-deficient fibroblasts for possible chemical chaperone therapy using N-octyl-4-epi-β-valienamine (NOEV) in patients with GM1-gangliosidosis and Morquio B disease estimated that the NOEV chaper one therapy will be effective in 20–40% of the patients.
Journal ArticleDOI
Initial clinical trial of a novel hemostat, TDM-621, in the endoscopic treatments of the gastric tumors
Masashi Yoshida,Naoki Goto,Minoru Kawaguchi,Hidehiko Koyama,Junko Kuroda,Tetsuji Kitahora,Hiroyuki Iwasaki,Shinji Suzuki,Mikinori Kataoka,Fujii Takashi,Masaki Kitajima +10 more
TL;DR: The feasibility of TDM‐621, the synthetic infectious agent‐free peptides, was tested in hemostasis of the bleeding after endoscopic treatments of the gastric tumors.
Journal ArticleDOI

Akira Matsuno,Hideki Katakami,Ryo Okazaki,So Yamada,Mitsuyoshi Sasaki,Hiroshi Nakaguchi,Shoko M. Yamada,Katsumi Hoya,Mineko Murakami,Kazuto Yamazaki,Yasuo Ishida,Hiroyuki Iwasaki,Jyunpei Kuyama,Kennichi Kakudo +13 more
TL;DR: The possibility of skull base metastasis from FTC should be considered in patients with clinical symptoms of cranial nerve dysfunction and radiological findings of bone destruction, and the results confirmed the presence of metastatic tumors in the skull base.
