title: Increase in a specific cytochrome P-450 isoenzyme in the liver of congenitally jaundiced Gunn rats.
abstract: Congenitally jaundiced (jj) Gunn rats had a greater hepatic microsomal content of a cytochrome P-450 isoenzyme, P-450c, than did the non-jaundiced (Jj) rats. No differences in content of P-450b, P-450d and pregnenolone-16 alpha-carbonitrile-induced (PCN) P-450 were found between jj and Jj rats. This is the first demonstration of a constitutive increase in a specific cytochrome P-450 isoenzyme in association with a genetic defect.
