The cholesterol side-chain cleavage enzyme, P450scc, initiates biosynthesis of all steroid hormones. Adrenal and gonadal P450scc expression requires steroidogenic factor-1 (SF1), but P450scc expression in human placental JEG-3 cells utilizes an SF1-i

Epidemiological studies have consistently shown that an early full-term pregnancy is protective against breast cancer. We hypothesize that the hormonal milieu that is present during pregnancy results in persistent changes in the pattern of gene expre

The role of testosterone (T) and 17 beta-estradiol (E2) in the control of chinook salmon gonadotropin II beta subunit (sGTHII beta) gene was examined. Both E2 and T specifically stimulated GTHII beta gene expression in cultured juvenile rainbow trout
Transcriptional and posttranscriptional regulation of human androgen receptor expression by androgen

Autoregulation is a control mechanism common to several proteins of the steroid/thyroid hormone receptor superfamily. In this work, the effect of androgens and antiandrogens on the expression of the human androgen receptor (hAR) in prostate and breas

The insulin-like growth factors (IGFs) are potent mitogens with both endocrine and autocrine-paracrine effects on cell growth. The IGF binding proteins (IGFBPs) are found in many human biological fluids and in the conditioned media of many cell cultu

In the steroidogenic pathways present in the gonads and adrenal cortex, 3 beta-hydroxysteroid dehydrogenase isomerase (3 beta HSD) is a key enzyme which controls the formation of delta 4-3-ketosteroids from delta 5-3 beta-hydroxysteroids. Herein, we

We have previously reported the immunohistochemical localization of transforming growth factor-alpha (TGF alpha) in the intact bovine anterior pituitary gland. Furthermore, we have purified TGF alpha from the conditioned medium of cell cultures deriv

The ability of high doses of cortisol to retard the involution process in the rat ventral prostate was related to alterations in the pattern of gene expression. Poly(A)+ RNA preparations from the prostates of noncastrated, castrated, and castrated ra

3T3-F442A cells differentiate from preadipocytes to adipocytes when cultured in medium containing fetal calf serum and insulin. We examined the regulation of the S14 gene in 3T3-F442A preadipocytes and adipocytes to determine whether these cells woul

To obtain information about the functional significance of the structural heterogeneity that has been described for rat insulin-like growth factor I (IGF-I) cDNAs, we hybridized polyadenylated RNAs from rat tissues at different developmental stages w
