BACKGROUND
Cortisol binding globulin (CBG) is produced by liver cells and is inhibited by proinflammatory cytokines such as interleukin (IL) 6. CBG serum levels are typically low during prolonged inflammatory processes. Thus, observed changes of cortisol during anti-tumour necrosis factor (TNF)
BACKGROUND
The human breast contains all the enzymes responsible for local bioformation of estradiol (E2). Two principal pathways are implicated in the last steps of E2 formation: the 'aromatase' which transforms androgens into estrogens, and the 'sulfatase' which converts estrogen sulfates into
To determine if delta 1-testololactone can inhibit the peripheral aromatization of androstenedione (delta), nine postmenopausal women with metastatic breast cancer were studied before and after 2 weeks of therapy with 250 mg of the drug, given every 6 h by mouth. The conversion ratio of delta to
The effect of the adrenal steroids androst-5-ene-3 beta,17 beta-diol (delta 5-diol) and androstenedione (delta 4-dione) was studied on the growth of mammary carcinoma induced in the rat by dimethylbenz[a]anthracene (DMBA). The plasma levels of the two steroids were maintained at values within the
Estrogens are involved in numerous physiological processes and have crucial roles in certain disease states such as mammary carcinoma. Estradiol, the most potent endogenous estrogen, is biosynthesized from androgens by the cytochrome P450 enzyme complex called aromatase. Aromatase is found in breast
Estrogens are involved in numerous physiologic processes and have crucial roles in particular disease states, such as mammary carcinomas. Estradiol, the most potent endogenous estrogen, is biosynthesized from androgens by the cytochrome P-450 enzyme complex called aromatase. Aromatase is found in
Extracts of black cohosh (Actaea racemosa) and soy are used as 'natural' alternatives to conventional hormone replacement therapy (HRT) and there is some evidence that soy may protect against breast cancer by inhibiting the production of active oestrogens. This study compares the action of ethanolic
OBJECTIVE
Adrenal androgens activate the androgen receptor and stimulate prostate cancer growth. Ketoconazole is used as an inhibitor of adrenal androgen synthesis in men with androgen-independent prostate cancer. This study analyzes the relationship between pretreatment androgen levels and outcome
The authors report a case of Leydig cell tumor in a 46-year-old woman who first presented with severe clinical hyperandrogenism and associated complex medical history. Investigations revealed markedly raised serum concentrations of testosterone (28.3 nmol/l) and free androgen index (54.4), whereas
Plasma and urinary steroid hormones were measured before and after an injection of human chorionic gonadotropin (hCG) to a postmenopausal woman with a mucinous ovarian tumor of borderline malignancy. Hormones were also measured in blood from a vein draining the tumor, and circulating gonadotropins
This Phase II study was designed to determine the efficacy and tolerability of vorozole (R83842), a new nonsteroidal aromatase inhibitor, in postmenopausal women with advanced breast cancer in progression being treated with tamoxifen, and to correlate these effects with the hormonal profile and
About one third of unselected postmenopausal women with advanced breast cancer respond to treatment with aminoglutethimide and hydrocortisone, but they all eventually relapse, and further progression of disease occurs. In this study, 36 patients who initially responded to this treatment were
A phase II study with cyproterone acetate (CPA) was done as the primary treatment in female breast cancer patients. Twenty-three patients, mean age 64 years, range 52-75 years, were entered and treated with CPA 400 mg daily. Twenty patients were evaluable and responses were sparse. There was one
In vitro, ketoconazole has been shown to block testicular and adrenal 17,20-lyase, which converts progestins to androgens. At higher concentrations, it also inhibits 11 beta-hydroxylase, 20,22-desmolase and 17 alpha-hydroxylase. To determine the differential hormonal effects of a 2-week ketoconazole
