Journal ArticleDOI
Antagonistic action of imidazolineoxyl N-oxides against endothelium-derived relaxing factor/.NO through a radical reaction.
Takaaki Akaike,Masaki Yoshida,Yoichi Miyamoto,Keizo Sato,Masahiro Kohno,Kazumi Sasamoto,Kiminori Miyazaki,Shoichi Ueda,Hiroshi Maeda +8 more
TL;DR: It was clarified that imidazolineoxyl N-oxide antagonize EDRF/.NO via a unique radical-radical reaction with .NO.
Journal ArticleDOI
Overexpression of B7-H1 (PD-L1) significantly associates with tumor grade and postoperative prognosis in human urothelial cancers.
TL;DR: The results demonstrate that the aberrant expression of B7-H1 in urothelial cancer is associated with aggressive tumors, suggesting a regulatory role of tumor-associated B7 H1 in antitumor immunity, and may become a beneficial target for immunotherapy in human uroclinical cancer.
Journal ArticleDOI
Age-related changes in cholinergic and purinergic neurotransmission in human isolated bladder smooth muscles
Masaki Yoshida,Yukio Homma,Akito Inadome,Makoto Yono,Hiroshi Seshita,Yutaka Miyamoto,Shigetaka Murakami,Kazuki Kawabe,Shoichi Ueda +8 more
TL;DR: The atropine sensitive and resistant parts of contraction induced by electrical field stimulation were decreased and increased with age, respectively, and the age-related changes in neurotransmissions may contribute to the changes in bladder function in the elderly.
Journal ArticleDOI
Therapeutic effects of imidazolineoxyl n-oxide against endotoxin shock through its direct nitric oxide-scavenging activity
Masaki Yoshida,Takaaki Akaike,Yoshihiro Wada,Keizo Sato,Kazuyoshi Ikeda,Shoichi Ueda,Hiroshi Maeda +6 more
TL;DR: It is indicated that carboxy-PTIO exhibits a potent therapeutic value in endotoxin shock through the direct scavenging action against NO.
Journal ArticleDOI
Ras Oncoprotein Induces CD44 Cleavage through Phosphoinositide 3-OH Kinase and the Rho Family of Small G Proteins
Yoshiaki Kawano,Isamu Okamoto,Daizo Murakami,Hiroshi Itoh,Masaki Yoshida,Shoichi Ueda,Hideyuki Saya +6 more
TL;DR: The results suggest that Ras > PI3K > Cdc42/Rac1 pathway plays an important role in CD44 cleavage and may provide a novel molecular basis to explain how the activated Ras facilitates cancer cell migration.
