UNLABELLED Intrahepatic cholestasis of pregnancy (ICP) is the most prevalent pregnancy-specific liver disease and is associated with an increased risk of adverse fetal outcomes, including preterm labor and intrauterine death. The endocrine signals that cause cholestasis are not known but 3α-sulfated progesterone metabolites have been shown to be elevated in(More)
Estrogens have an important role in the development and progression of breast cancer. 17beta-Hydroxysteroid dehydrogenase type 1 (17HSD1), type 2 (17HSD2), and type 5 (17HSD5) are associated with sex steroid metabolism in normal and cancerous breast tissue. The mRNA expressions of the 17HSD1, 17HSD2, and 17HSD5 enzymes were analyzed in 794 breast carcinoma(More)
17 beta-Hydroxysteroid dehydrogenases (17HSDs) catalyze the interconversions between active 17 beta-hydroxysteroids and less-active 17-ketosteroids thereby affecting the availability of biologically active estrogens and androgens in a variety of tissues. The enzymes have different enzymatic properties and characteristic cell-specific expression patterns,(More)
The 17 beta-hydroxysteroid dehydrogenase (17HSD) enzymes are involved in the regulation of the biological activity of sex steroids. We analyzed the expression of 17HSD type 1 and 2 enzymes which catalyze opposite reactions of estrogen metabolism, in normal gastric mucosa and various gastric diseases of 81 tissue specimens. No expression of 17HSD type 1 mRNA(More)
Nuclear receptor interacting protein (Nrip1), also known as RIP140, is a co-regulator for nuclear receptors that plays an essential role in ovulation by regulating the expression of the epidermal growth factor-like family of growth factors. Although several studies indicate a role for RIP140 in breast cancer, its role in the development of the mammary gland(More)
The biological characteristics of prostate-specific antigen were studied in the Nigerian African. Two hundred and fourteen persons were selected for the study. The group was made up of 59 apparently healthy men (age range 22-76 years), 58 men (age range 40-91 years) who had biopsy proven diagnosis of cancer of the prostate gland, 81 men (age range 46-87(More)
The mRNA expression of 17beta-hydroxysteroid dehydrogenase (17HSD) types 1 and 2 enzymes catalyzing opposite reaction of estrogen metabolism was investigated in colon cancer. Further, the significance of the 17HSD type 2 enzyme as a possible marker of colorectal cancer (CRC) prognosis was studied. In the normal mucosa, 17HSD type 2 mRNA was predominantly(More)
17 beta-Hydroxysteroid dehydrogenases (17HSDs) regulate the biological activity of sex steroid hormones in a variety of tissues by catalyzing the interconversions between highly active steroid hormones, e.g. estradiol and testosterone, and corresponding less active hormones, estrone and androstenedione. Epidemiological and endocrine evidence indicates that(More)
The 17HSDs are a group of isozymes that catalyze the interconversion between high-activity 17 beta-hydroxysteroids and low-activity 17-ketosteroids. In the present study, we characterized the expression of 17HSD types 1 and 2 in normal and malignant gastrointestinal tissues and cells. Using the colon as a model for cancer of the gastrointestinal tract,(More)
Estrogen action plays a crucial role in many processes throughout the human life span, including development. Estrogens are pivotal in the regulation of female reproduction, but little is known about their role during ovarian development. To better understand estrogen action during ovarian development, the expression of estrogen receptors (ERs)-alpha and(More)
