Hydroxylation and sulfation of sex steroid hormones in inflammatory liver

Sex steroids, also known as gonadal steroids, are oxidized with hydroxylation by cytochrome P450, glucuronidation by UDP-glucuronosyltransferase, sulfation by sulfotransferase, andO-methylation by catechol O-methyltransferase. Thus, it is important to determine the process by which inflammation influences metabolism of gonadal hormones. Therefore, we investigated the mechanism of metabolic enzy...

Effect of androgen and estrogen on the hydroxylation of steroid hormones by rat liver microsomes.

Castration in male rats decreased the activities of testosterone and progesterone hydroxylations and reduced the magnitude of spectral change caused by testosterone and progesterone in liver microsomes, accompanying less marked decrease in microsomal P-450 content and NADPH-neotetrazolium reductase activities. The administration of testosterone or methyltestosterone to the castrated rats comple...

The correlation of anandamide with gonadotrophin and sex steroid hormones during the menstrual cycle

Objective(s): The purpose of this study was to investigate the change in plasma anandamide (AEA) levels throughout the normal menstrual cycle, and to analyze the relationship among AEA, sex steroids and gonadotrophins. Materials and Methods: The patients were fertile women with normal menstrual cycle, proposed to get in vitro fertilization (IVF) treatment due to oviduct obstruction or male infe...

[Decreased hydroxylation of steroid hormones by liver microsomes from rats bearing Walker carcinosarcoma 256].

The hydroxylating activities of liver microsomes for proges terone and testosterone were markedly decreased in male and female rats bearing Walker carcinosarcoma 256. The decreases in the hydroxylating activities were greater in the male rats than in the female rats. The content of cytochrome P-450 in liver microsomes was decreased in the tumor-bearing male and female rats. Moreover, the bindin...

Acetaminophen (Paracetamol) Use Modifies the Sulfation of Sex Hormones

BACKGROUND Acetaminophen (paracetamol) is one of the most common medications used for management of pain in the world. There is lack of consensus about the mechanism of action, and concern about the possibility of adverse effects on reproductive health. METHODS We first established the metabolome profile that characterizes use of acetaminophen, and we subsequently trained and tested a model t...
