Effects of piperonyl butoxide and β-naphthoflavone on cytochrome P4501A expression and activity in Atlantic salmon (Salmo salarL.)

Autor: Bjørn Einar Grøsvik, Håvard E. Larsen, Anders Goksøyr

Publikováno v: Environmental Toxicology and Chemistry. 16:415-423

The effects of piperonyl butoxide (PBO) and β-naphthoflavone (BNF) on cytochrome P4501A (CYP1A) expression and activity in juvenile Atlantic salmon (Salmo salar L.) with regard to time and temperature was investigated. The time exposure study was pe

Juvenile Atlantic cod were placed in net cages on the bottom at 20–30 m depth at four sites from the inner end of Sorfjorden (Hardanger, Western Norway), to the northern mouth of the fjord in October 1990. After 4 weeks the fish were killed, and li

Cytochrome P450 in seals: monooxygenase activities, immunochemical cross-reactions and response to phenobarbital treatment

Autor: Jonny Beyer, Håvard E. Larsen, Lars Förlin, Anders Goksøyr, Tommy Andersson

Publikováno v: Marine Environmental Research. 34:113-116

Cytochrome P450 monooxygenase activities, reflecting the expression of various subfamilies of P450, were measured in liver samples of harp and hooded seal. Differences in some of the investigated parameters were observed between the two species, betw

Application of a cytochrome P-450 IA1-ELISA in environmental monitoring and toxicological testing of fish

Autor: Astrid-Mette Husøy, Håvard E. Larsen, Anders Goksøyr

Publikováno v: Comparative Biochemistry and Physiology Part C: Comparative Pharmacology. 100:157-160

1. An enzyme-linked immunosorbent assay (ELISA) based on polyclonal rabbit anti-cod cytochrome P-450 IA1 IgG has been developed in our laboratory. 2. The antibodies employed in the ELISA demonstrate good cross-reactivity with the homologous protein i

The cytochrome P450 system of Atlantic salmon (Salmo salar): II. Variations in hepatic catalytic activities and isozyme patterns during an annual reproductive cycle

Autor: Anders Goksøyr, Håvard E. Larsen, Malin Celander

Publikováno v: Fish physiology and biochemistry. 10(4)

A group of Atlantic salmon (Salmo salar) was followed through their first year of maturation and spawning. At monthly intervals, starting with juvenile fish in December, 5–7 fish of each sex were killed, and liver and plasma were sampled. The last

The cytochrome P450 system of atlantic salmon (Salmo salar): I. Basal properties and induction of P450 1A1 in liver of immature and mature fish

Autor: Anders Goksøyr, Håvard E. Larsen

Publikováno v: Fish physiology and biochemistry. 9(4)

The major components of the cytochrome P450 (P450) system in liver microsomes of Atlantic salmon were studied using spectrophotometric, catalytic and immunochemical techniques. In juvenile fish sampled during the winter season, high basal activities
