Influence of tea and coffee on biomonitoring of toluene exposure (2009)

Munaka, Masahiro, Katoh, Takahiko, Kohshi, Kiyotaka, Sasaki, Satomi

Background The intake of some benzoic acid-containing foods or drinks such as green tea and coffee is known to increase urinary hippuric acid (HA) concentrations, and, unless this can be accounted...

Replication of Prostate Cancer Risk Loci in a Japanese Case-Control Association Study (2009)

Yamada, Hiroki, Penney, Kathryn L., Takahashi, Hiroyuki, Katoh, Takahiko, Yamano, Yuko, Yamakado, Minoru, ...

Background Two prostate cancer genome-wide scans in populations of European ancestry identified several genetic variants that are strongly associated with prostate cancer risk. The effect of these...

Interaction between cytochrome P450 gene polymorphisms and serum organochlorine TEQ levels in the risk of endometriosis (2007)

Tsuchiya, Masaki, Tsukino, Hiromasa, Iwasaki, Motoki, Sasaki, Hiroshi, Tanaka, Tadao, Katoh, Takahiko, ...

Exposure to dioxins and polychlorinated biphenyls (PCBs) has been suggested as a possible etiologic factor for endometriosis, but the association remains highly controversial. To assess whether...

Pooled Analysis and Meta-analysis of Glutathione S-Transferase M1 and Bladder Cancer: A HuGE Review (2002)

Engel, Lawrence S., Taioli, Emanuela, Pfeiffer, Ruth, Garcia-Closas, Montserrat, Marcus, Pamela M., Lan, Qing, ...

Smoking is a known risk factor for bladder cancer. The product of the GSTM1 gene, glutathione S-transferase M1 (GSTM1), is involved in the detoxification of polycyclic aromatic hydrocarbons found in...

Sulfating-Activity and Stability of cDNA-Expressed Allozymes of Human Phenol Sulfotransferase, ST1A3*1 (213Arg) and ST1A3*2 (213His), Both of Which Exist in Japanese as Well as Caucasians (1999)

Ozawa, Shogo, Shimizu, Makiko, Katoh, Takahiko, Miyajima, Atsuko, Ohno, Yasuo, Matsumoto, Yoshiaki, ...

We recently found single amino acid substitutions (J13Arg/His and 223Met/Val) in polymorphic human phenol-sulfating phenol sulfotransferase (SULT: cDNAs encoding ST1A3, P PST or HAST1/2) among...

Glutathione S-transferase M1 (GSTM1) and T1 (GSTT1) genetic polymorphism and susceptibility to gastric and colorectal adenocarcinoma (1996)

Katoh, Takahiko, Nagata, Naoki, Kuroda, Yusuke, Itoh, Hideaki, Kawahara, Akio, Kuroki, Nobuyoshi, ...

Genes coding for the glutatione S-transferase M1 (GSTM1) and Theta 1 (GSTT1) proteins are polymorphic in humans and these genes are absent, or homozygous null, in 10–60% of different ethnic...

Cytochrome P4501A1 gene polymorphism and homozygous deletion of the glutathione S-transferase M1 gene in urothelial cancer patients (1995)

Katoh, Takahiko, Inatomi, Hisato, Nagaoka, Akira, Sugita, Atsuo

Japanese urothelial (bladder, renal pelvis and ureter) cancer patients (n = 83) and community controls (n = 101) were compared for rates of polymorphism in exon 7 of the cytochrome...

Comparison of Ki-ras gene mutation among simultaneously occurring multiple urethan-induced lung tumors in individual mice (1992)

Ohmori, Hisamitsu, Abe, Tetsuya, Hirano, Hideyasu, Murakami, Tadamasa, Katoh, Takahiko, Gotoh, Sadao, ...

Mouse lung tumors were induced in C57BL/6J(female) � A/J(male) F1 mice by a single s.c. injection of urethan. About 6 months later, multiple small-sized lung tumors were detectable in almost all...
