TL;DR: Growth inhibition by sulfa drugs was reduced by the addition of folic acid, indicating that they inhibit folate synthesis in green algae.
Journal ArticleDOI
Fluorescent Probes for Hydrogen Peroxide Based on a Non‐Oxidative Mechanism
Hatsuo Maeda,Yuka Fukuyasu,Shoko Yoshida,Masako Fukuda,Kanako Saeki,Hiromi Matsuno,Yuji Yamauchi,Kenji Yoshida,Kazumasa Hirata,Kazuhisa Miyamoto +9 more
Journal ArticleDOI

Yuko Ueda,Ikumi Ooshio,Yasuyuki Fusamae,Kaori Kitae,Megumi Kawaguchi,Kentaro Jingushi,Hiroaki Hase,Kazuo Harada,Kazumasa Hirata,Kazutake Tsujikawa +9 more
TL;DR: This study found that ALKBH3 effectively demethylated 1-meA and 3-meC within endogenously methylated RNA and identified N6-methyladenine in mammalian transfer RNA (tRNA) as a novel AL KBH3 substrate.
Journal ArticleDOI
Prediction of interindividual differences in hepatic functions and drug sensitivity by using human iPS-derived hepatocytes
Kazuo Takayama,Yuta Morisaki,Shuichi Kuno,Yasuhito Nagamoto,Kazuo Harada,Norihisa Furukawa,Manami Ohtaka,Ken Nishimura,Kazuo Imagawa,Fuminori Sakurai,Masashi Tachibana,Ryo Sumazaki,Emiko Noguchi,Mahito Nakanishi,Kazumasa Hirata,Kenji Kawabata,Hiroyuki Mizuguchi +16 more
TL;DR: It is found that cytochrome P450 metabolism capacity and drug responsiveness of the primary human hepatocytes–human induced pluripotent stem cells–hepatocyte-like cells (PHH-iPS-HLCs) were highly correlated with those of PHHs, suggesting that the PHH- iPS- HLCs retained donor-specific CYP metabolism capacityand drug responsiveness.
Journal ArticleDOI
Biosynthetic regulation of phytochelatins, heavy metal-binding peptides
TL;DR: Recent advances in the understanding of the molecular mechanisms for PC biosynthesis and functions are introduced in order to supply basic information about the unique and attractive peptides applicable to various fields.
