Recently, several LH/human chorionic gonadotropin (hCG) receptor-independent activities for hCG have been described, including activation of the TGF-β receptor (TGFβR) by hyperglycosylated hCG and stimulation of trophoblast invasion. Because the hC

We have identified Kruppel-like factor 7 (KLF7) as a new candidate for conferring susceptibility to type 2 diabetes. To ascertain the possible involvement of KLF7 in the pathogenesis of type 2 diabetes, we examined the functional roles of KLF7 in var

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

As pituitary leukemia-inhibitory factor (LIF) mediates neuroimmune signals to the hypothalamo-pituitary-adrenal axis, we tested the role of intracellular SOCS-3 in corticotroph function. SOCS-3, a cytokine-inducible protein of the suppressor of cytok

In this report we show that extracellular signal-regulated kinase-1 and -2 (ERK-1 and -2) respond differently to signals that elicit proliferation and/or differentiation of myoblasts using the C2C12 cell line and nondifferentiating mutant NFB4 cells

A GnRH-expressing neuronal cell line (NLT) was used to determine whether insulin-like growth factor I (IGF-I) regulates GnRH gene expression. A receptor-binding assay demonstrated the expression of IGF-I receptors on NLT cells. Activation of IGF-I re

The growth-promoting activity of GH, the principal hormonal determinant of body size, is mediated by insulin-like growth factor I (IGF-I). Most of the IGF-I in plasma circulates in a 150-kDa complex that contains IGF-binding protein-3 (IGFBP-3) and a

Transplantation of GH3 rat pituitary tumor cells that express both PRL and GH to female Wistar-Furth rats results in tumors that secrete only GH. We have used in vivo passage of GH3 cells as a model system to study specific repression of PRL. RNA blo

Despite detailed knowledge of the regulation of individual steps in the gluconeogenic pathway, the relative importance of each step to the overall control of gluconeogenesis by insulin is not known. The aim of this study was to determine the role of

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
