The effectiveness of estrogens in stimulating gene transcription mediated by the estrogen receptor (ER) appears to depend on ER interactions with coactivator proteins. These coactivators bind to ER when it is liganded with an estrogen agonist, but not when it is liganded with an estrogen antagonist. Because estrogen agonists are known to induce a(More)
Currently, the method most used for gene detection calls on Affy-metrix oligonucleotide arrays is provided as part of the MAS5.0 software. The MAS method uses Wilcoxon statistics for determining presence-absence (MAS-P/A) calls. It is known that MAS-P/A is limited by its need to use both perfect match (PM) and mismatch (MM) probe data in order to call a(More)
Estrogens exert profound effects on the physiology of diverse target cells and these effects appear to be mediated by two estrogen receptor (ER) subtypes, ERalpha and ERbeta. We have investigated how ER ligands, ranging from pure agonists to antagonists, interact with ERalpha and ERbeta, and regulate their transcriptional activity on different genes.(More)
We have identified a novel DEAD box RNA helicase (97 kDa, DP97) from a breast cancer cDNA library that interacts in a hormone-dependent manner with nuclear receptors and represses their transcriptional activity. DP97 has RNA-dependent ATPase activity, and mapping studies localize the interacting regions of DP97 and nuclear receptors to the C-terminal region(More)
Gene expression studies have been widely used in an effort to identify signatures that can predict clinical progression of cancer. In this study we focused instead on identifying gene expression differences between breast tumors and adjacent normal tissue, and between different subtypes of tumor classified by clinical marker status. We have collected a set(More)
The estrogen receptor (ER), a member of the nuclear hormone receptor superfamily, is a hormone-regulated transcription factor that mediates the effects of estrogens and antiestrogens in breast cancer and other estrogen target cells. Because of the role of estrogens in promoting the growth and progression of breast cancer, there is great interest in(More)
Gonadotropin-releasing hormone (GnRH) receptors are expressed in prostate cancer, specifically in the most aggressive stage of the tumor (castration-resistant prostate cancer, CRPC) for which the standard treatment, docetaxel-based chemotherapy, can only improve the median survival time by few months. We previously showed that GnRH agonists exert an(More)
Although the prevalence of fully expressed Eating Disorders is rare in young children, childhood eating disturbances are fairly common. Parents can play a facilitating role for the development of overweight and eating problems among their children. The aim of this study is to detect the possible relationships between children's eating attitudes and(More)
