Abstract
A synthetic bacterial luciferase-based autobioluminescent bioreporter, HEK293ERE/Gal4-Lux, was developed in a human embryonic kidney (HEK293) cell line for the surveillance of chemicals displaying endocrine disrupting activity. Unlike alternative luminescent reporters, this bioreporter generates bioluminescence autonomously without requiring an external light-activating chemical substrate or cellular destruction. The bioreporter's performance was validated against a library of 76 agonistic and antagonistic estrogenic endocrine disruptor chemicals and demonstrated reproducible half maximal effective concentration (EC50) values meeting the U.S. Environmental Protection Agency (EPA) guidelines for Tier 1 endocrine disrupting chemical screening assays. For model compounds, such as the estrogen receptor (ER) agonist 17β-estradiol, HEK293ERE/Gal4-Lux demonstrated an EC50 value (7.9 × 10-12 M) comparable to that of the current EPA-approved HeLa-9903 firefly luciferase-based estrogen receptor transcription assay (4.6 × 10-12 M). Screening against an expanded array of common ER agonists likewise produced similar relative effect potencies as compared with existing assays. The self-initiated autobioluminescent signal of the bioreporter permitted facile monitoring of the effects of endocrine disrupting chemicals, which decreased the cost and hands-on time required to perform these assays. These characteristics make the HEK293ERE/Gal4-Lux bioreporter potentially suitable as a high-throughput human cell-based assay for screening estrogenic activity.

Abstract
The function of steroid receptors is not only regulated by steroid hormones, but also by multiple cellular signaling cascades activated by membrane-bound receptors which are stimulated by growth factors or cytokines. Cross-talk between JAK and steroid receptors plays a central role in the regulation of a multitude of physiological processes and aberrant signaling is involved in the development of numerous diseases including cancer. In this review we provide a brief summary of the knowledge of interactions between JAK and the function of steroid receptors in normal cells and tissues and in diseases.

The influence of estrogens on the biological and therapeutic actions of growth hormone in the liver. Pharmaceuticals (Basel) 2012; 5:758-78.

Abstract
GH is main regulator of body growth and composition, somatic development, intermediate metabolism and gender-dependent dimorphism in mammals. The liver is a direct target of estrogens because it expresses estrogen receptors which are connected with development, lipid metabolism and insulin sensitivity, hepatic carcinogenesis, protection from drug-induced toxicity and fertility. In addition, estrogens can modulate GH actions in liver by acting centrally, regulating pituitary GH secretion, and, peripherally, by modulating GHR-JAK2-STAT5 signalling pathway. Therefore, the interactions of estrogens with GH actions in liver are biologically and clinically relevant because disruption of GH signaling may cause alterations of its endocrine, metabolic, and gender differentiated functions and it could be linked to dramatic impact in liver physiology during development as well as in adulthood. Finally, the interplay of estrogens with GH is relevant because physiological roles these hormones have in human, and the widespread exposition of estrogen or estrogen-related compounds in human. This review highlights the importance of these hormones in liver physiology as well as how estrogens modulate GH actions in liver which will help to improve the clinical use of these hormones.

Abstract
Mouse models of cystic fibrosis (CF) display increased sulfotransferase 1E1 (SULT1E1) activity in hepatocytes of cystic fibrosis transmembrane receptor (CFTR)-deficient animals. SULT1E1 is responsible for the sulfation and inactivation of beta-estradiol (E2) at physiological concentrations. IGF-1 message levels in CFTR(-/-) mouse livers were positively correlated with body weight and negatively correlated with SULT1E1 activity. Growth hormone (GH) is important in the regulation of hepatic IGF-1 expression indicating that E2 levels are involved with GH signaling in hepatocytes. To investigate the effects of E2 and SULT1E1 activity on GH signal transduction in human hepatocytes, SULT1E1 was stably expressed in HepG2 cells. Effects of increased E2 sulfation on the GH signaling pathway and E2-regulated gene expression were examined. Pretreatment of HepG2 cells with 10nM E2 prior to GH stimulation increased STAT5b phosphorylation and IGF-1 expression. In SULT1E1-transfected HepG2 cells, GH-stimulated STAT5b phosphorylation was significantly decreased. E2 treatment had no effect on STAT5b phosphorylation in the absence of GH stimulation. E2 also had no effect on Jak-2 phosphorylation. E2 has an apparent rapid action on increasing GH-stimulated STAT5b phosphorylation that was not attenuated by the estrogen receptor antagonist, ICI 182,780. Physiological levels of E2 in HepG2 cells increase GH stimulation of IGF-1 production apparently through increased phosphorylated STAT5b levels and transcriptional activation of the IGF-1 gene. The enhanced SULT1E1 activity may have a role in inhibiting GH-stimulated STAT5b phosphorylation and IGF-1 synthesis via the sulfation and inactivation of E2.

Abstract
BACKGROUND Functional development of the prostate is governed by stromal mesenchyme induction and epithelial response. Stromal/epithelial signaling can be mediated through direct cell-cell contact and diffusible factors and their cell surface receptors. These inducers are likely secreted or membrane-associated extracellular proteins. Given the importance of intercellular communication, it is possible that diseases like cancer could arise from a loss of this communication. One approach to gain a molecular understanding of stromal cells is to identify, as a first step, secreted stromal signaling factors. We proposed to do this by comparative analysis between bladder and prostate. METHODS Secreted proteins were identified from cultured normal prostate and bladder stromal mesenchyme cells by glycopeptide-capture method followed by mass spectrometry. Differences in protein abundance between prostate and bladder were quantified from calculated peptide ion current area (PICA) followed by Western validation. Functional and pathway analyses of the proteins were carried out by Gene Ontology (GO) and Teranode software. RESULTS This analysis produced a list of 116 prostate and 84 bladder secreted glycoproteins with ProteinProphet probability scores > or =0.9. Stromal proteins upregulated in the prostate include cathepsin L, follistatin-related protein, neuroendocrine convertase, tumor necrosis factor receptor, and others that are known to be involved in signal transduction, extracellular matrix interaction, differentiation and transport. CONCLUSIONS We have identified a number of potential proteins for stromal signaling and bladder or prostate differentiation program. The prostate stromal/epithelial signaling may be accomplished through activation of the ECM-receptor interaction, complement and coagulation cascades, focal adhesion and cell adhesion pathways.
