Strain differences in rat liver (UDP-glucuronyltransferase activity towards androsterone.
نویسندگان
چکیده
Male Donryu, Wistar King rats showed discontinuous variations in hepatic microsomal UDP-glucuronyltransferase activities towards androsterone, but not towards testosterone, bilirubin, phenolphthalein and 4-nitrophenol. Fresh microsomal fraction with a low transferase activity towards androsterone formed 0.049--0.080 nmole of glucuronide/min per mg of protein, whereas fresh microsomal fraction with a high transferase activity towards androsterone formed 0.335--0.557 nmol of glucuronide/min per mg of protein. The microsomal fraction with low enzyme activity towards androsterone was not stimulated by treatment with Triton X-100 or freezing and thawing. In contrast, male Long Evans and Sprague-Dawley rats did not exhibit such diversity.

Glucuronidation of bile acids by rat liver 3-OH androgen UDP-glucuronyltransferase.
The glucuronidation of bile acids is an important pathway for the detoxification and elimination of retained bile acids during cholestasis. A 3-OH-specific androgen UDP-glucuronyltransferase was purified from solubilized female rat liver microsomes using Chromatofocusing and UDP- hexanolamine -Sepharose 4B affinity chromatography. The purified 3-OH androgen UDP-glucuronyltransferase is reactive...

UDP-glucuronyltransferase activities towards 4-nitrophenol, bilirubin, 1-naphthol and morphine were co-immunoprecipitated from solubilized Wistar-rat liver preparations. 3. UDP-glucuronyltransferase activities towards 1-naphthol, 2-aminophenol and 4-nitrophenol were precipitated from solubilized Gunn-rat liv...
متن کاملClassification and genetic expression of Wistar rats with high and low hepatic microsomal UDP-glucuronosyltransferase activity towards androsterone.
Male and female Wistar rats with high and low hepatic microsomal UDP-glucuronosyltransferase activity towards androsterone were classified by partial hepatectomy. The breeding experiments between the classified high-activity and low-activity rats show that the genetic expression of the high transferase activity is inherited in an autosomal dominant fashion.
متن کاملThe full length coding sequence of rat liver androsterone UDP-glucuronyltransferase cDNA and comparison with other members of this gene family.
Cloned cDNAs coding for hepatic UDP-glucuronyltransferase (UDPGT) have been isolated from a rat liver cDNA library in the expression vector bacteriophage lambda gt11 using anti-UDPGT antibodies. Four different mRNAs have been identified by sequencing of 15 UDPGT cDNA clones. The sequences of the four classes of cDNA were determined to be 85-95% homologous. Restriction fragments were isolated fr...

Qualitative and quantitative differences of purified hepatic 3 alpha-hydroxysteroid UDP-glucuronosyltransferase were investigated in Wistar and Sprague-Dawley rats. Individual differences in the glucuronidation rate of androsterone and chenodeoxycholic acid were observed in hepatic microsomal fractions from Wistar but not Sprague-Dawley rats. No individual variation was observed in the glucuron...
