1 Induction of rat liver microsomal epoxide hydrolase by thiazole and pyrazine: hydrolysis of 2-cyanoethylene oxide. Pyrazines epoxide hydrolase 1 Rattus norvegicus
2 Immunoblot analyses using rabbit anti-rat mEH antibody revealed a significant increase in mEH levels in hepatic microsomes isolated from either thiazole- or pyrazine-treated animals. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
3 Immunoblot analyses using rabbit anti-rat mEH antibody revealed a significant increase in mEH levels in hepatic microsomes isolated from either thiazole- or pyrazine-treated animals. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
4 Another protein (approximately 43 kd) cross-reacting with polyclonal mEH antibody was found to be increased concomitantly following pyrazine treatment. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
5 Northern and slot blot analyses showed substantial increases in mEH mRNA following either thiazole or pyrazine treatment. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
6 Approximately 20- and 16-fold increases in mEH mRNA were also observed at 48 and 72 h respectively following treatment with pyrazine. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
7 The level of polymerase chain reaction (PCR)-amplified mEH DNA derived from poly(A)+ RNA was clearly elevated following either thiazole or pyrazine treatment relative to that from untreated animals. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
8 These kinetic data correlate well with the increases in mEH mRNA observed after administration of thiazole or pyrazine to rats. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
9 These results provide evidence that administration of thiazole or pyrazine induces mEH with a large increase in mEH mRNA, and that the induced mEH catalyzes the hydrolysis of CEO. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
10 These results provide evidence that administration of thiazole or pyrazine induces mEH with a large increase in mEH mRNA, and that the induced mEH catalyzes the hydrolysis of CEO. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
11 These results provide evidence that administration of thiazole or pyrazine induces mEH with a large increase in mEH mRNA, and that the induced mEH catalyzes the hydrolysis of CEO. Pyrazines epoxide hydrolase 1, microsomal Mus musculus
