Cloning, characterization and validation of inosine 5′-monophosphate dehydrogenase of Babesia gibsoni as molecular drug target
Xuan, Xuenan; Nishikawa, Yoshifumi; Igarashi, Ikuo; Suzuki, Hiroshi; Masatani, Tatsunori; Kamyingkird, Ketsarin; Goo, Younkyoung; Li, Yan; Yu, Longzheng; Luo, Yuzi; Zhou, Mo; Terkawi, Mohamad A; Aboge, Gabriel O; Cao, Shinuo (Department of Public Health, Pharmacology and Toxicology, 2013-04)The inosine monophosphate dehydrogenase (IMPDH) enzyme has been characterized and validated as a molecular drug target in other apicomplexans but not in the genus Babesia. Subsequently, we cloned and expressed a Babesia ... -
Cloning, Expression, and Characterization of Babesia gibsoni Dihydrofolate Reductase-Thymidylate Synthase: Inhibitory Effect of Antifolates on Its Catalytic Activity and Parasite Proliferation
Aboge, Gabriel O; Terkawi, Mohamad A; Goo, Youn-Kyoung; Nishikawa, Yoshifumi; Sunaga, Fujiko; Namikawa, Kuzuhiko; Tsuji, Naotoshi; Igarashi, Ikuo; Suzuki, Hiroshi; Fujisaki, Kozo; Xuan, Xuenan (Department of Public Health Pharmacology and Toxicology, 2008)Dihydrofolate reductase-thymidylate synthase (DHFR-TS) is a well-validated antifolate drug target in certain pathogenic apicomplexans, but not in the genus Babesia, including Babesia gibsoni. Therefore, we isolated, cloned, ... -
Identification of Secreted Antigen 3 from Babesia gibsoni
Jia, Honglin; Terkawi, M. Alaa; Aboge, Gabriel Oluga; Goo, Youn-Kyoung; Ma, Liqing; Zhou, Jinlin; Nishikawa, Yoshifumi; Igarashi, Ikuo; Fujisaki, Kozo; Xuan, Xuenan (Department of Public Health, Pharmacology and Toxicology, 2009)A cDNA expression library of Babesia gibsoni was screened with the serum collected from a dog experimentally infected with B. gibsoni. A novel antigen sharing homology with secreted antigen 1 of B. gibsoni was isolated. ... -
