Available in PDF, EPUB and Kindle. Book excerpt: Estrogen signaling is primarily mediated by two estrogen receptors (ERs), ER[alpha] and ER[beta]. ER[alpha] is expressed in ~70% of breast cancers and is an important diagnostic and therapeutic target. Developing better treatment options and overcoming limitations of endocrine therapy depend on a detailed understanding of ER[alpha]-signaling pathways. ER[alpha], a member of the class I nuclear receptor superfamily of transcription factors, localizes mainly to the nucleus and interacts with DNA regulatory sequences either directly or through interaction with other transcription factors to regulate gene transcription. ER[alpha] is also rapidly activates signaling cascades. S-palmitoylation, a reversible lipid modification is catalyzed by palmitoyl acyl-transferases (PAT), which increase affinity of proteins to the membrane. Based on the results of previous studies, it is hypothesized that palmitoylation of ER[alpha] regulates extranuclear and nuclear signaling of ER[alpha]. We utilized palmitoylation-defective mutant ER[alpha]C447A-expressing MDA-MB-468 breast cancer cells to dissect the role of palmitoylation in a breast cancer cell line model. The substitution of ER[alpha] palmitoylation site abrogated ER[alpha] palmitoylation, membrane localization and estrogen-dependent phosphorylation of ERK1/2 in MDA-MB-468 cell line. Besides loss of E2-dependent extranuclear signaling, the substitution of palmitoylation sites led to the loss of other ER[alpha]-dependent events in ER[alpha]C447A-expressing MDA-MB-468 cells, such as decreased E2-dependent S118 phosphorylation, impaired regulation of certain target genes, and loss of estrogen-dependent cell cycle inhibition. This study thus highlights the importance of ER[alpha] palmitoylation in both nuclear and extranuclear ER signaling pathways in breast cancer cells. A better understanding of the mechanisms of estrogen action will help us to design more effective drugs affecting signal pathways depending on both membrane and nuclear receptors.

Available in PDF, EPUB and Kindle. Book excerpt: The discovery of ER by Dr. Elwood Jensen exactly 60 years ago has not only led to the birth of a whole new vital nuclear receptor research field but also made a rapid, direct and lasting impact on the treatment and prevention of breast cancer. Since that landmark discovery, tremendous progress has been made in our understanding of the molecular functions of ER and development of targeted therapies against ER pathways for breast cancer treatment. However, there is currently no book available addressing these discoveries and recent advancement in a historical and systematic fashion. This book is intended to provide comprehensive, most up-to-date information on the history and recent advancement of ER and breast cancer by world renowned leaders in the field. These chapters include the history of the discovery of ER; physiological and pathological roles of ER; recent discovery of ER cistrome, transcriptome and its regulation of noncoding RNAs such as microRNAs and enhancer RNAs in breast cancer; development and clinical practices of the first targeted therapy Tamoxifen and other antiestrogens for breast cancer treatment; structural basis of ER and antiestrogen actions; molecular insights into endocrine resistance; the role of ER mutants, ER-beta and environmental estrogens in breast cancer; and emerging state-of-the-art therapeutic approaches currently in development to overcome treatment resistance and future perspectives. The book will provide undergraduate and graduate students, basic scientists and clinical cancer researchers, residents, fellows, as well as clinicians, oncology educators and the general public a thorough and authoritative review of these exciting topics.

Download or read book Mechanisms of Transcriptional Activation of Estrogen Responsive Genes in Breast Cancer Cells written by Chien-Cheng Chen and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Estrogen receptor (ER) acts as a ligand-activated transcription factor that regulates the expression of genes. The genomic mechanisms of ER action include ligand-induced dimerization of ER which binds estrogen responsive elements (EREs) in the promoters of target genes. There are also nongenomic mechanisms of ER action which are associated with membrane bound or cytosol ER-dependent activation of various protein-kinase cascades which also influence expression of target genes. Egr-1 is an immediate-early gene induced by 17B-estradiol (E2) in the rodent uterus and breast cancer cells. Deletion analysis of the Egr-1 promoter identified a minimal E2-responsive region that contained serum response element (SRE3) which bound Elk-1 and serum response factor (SRF) in gel mobility shift assays. Hormone-responsiveness of Egr-1 in MCF-7 cells was specifically inhibited by PD98059, a MAPKK inhibitor, but not by LY294002, an inhibitor of PI3-K. These results contrasted with the hormone-dependent activation of the SRE in the c-fos promoter, which was inhibited by both PD98059 and LY294002, suggesting that Egr-1, like c-fos, is activated through non-genomic pathways of estrogen action but through activation of different kinases. COUP-TFs are orphan nuclear receptors expressed in a variety of tissues where they regulate biological functions and organogenesis. In this study, we investigated coactivation of ERa by COUP-TF1 in cell lines transiently cotransfected with the pERE3 construct. COUP-TFI coactivated ERał-mediated transactivation, but unlike many other coactivators, COUP-TFI also enhanced transactivation of ERa when cells were cotransfected with the TAF1-ERa mutant or the 19c-ERa mutant. These data indicate that helix 12 of ERa is not required for coactivation by COUP-TFI when AF-1 of ERa is intact. However, when the AF-1 of ERa is deleted, the intact AF-2 function is required for coactivation by COUP-TFI. Analysis of multiple COUP-TFI deletion mutants showed that the DNA-binding domain and C-terminal region of COUP-TFI were important for coactivation of ERa. Point mutations of the DNA-binding domain of COUP-TFI resulted in loss of interactions with ERa, suggesting that the DNA-binding domain of COUP-TFI is important for its coactivation activity facilitating interactions with ERa. These results demonstrate that COUP-TFI coactivated ERa through a non-classical LXXLL-independent pathway.

Korach and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: From our current knowledge, it is obvious that estrogen action in volves more than reproduction and fertility. Rather, estrogens affect and influence a number of other organ systems such as the immune, cardiovascular and central nervous system as well as the gastrointes tinal tract, urinary tract and skeleton. The importance of estrogens and estrogen receptor activity is appreciated from the spectrum of significant physiological dysfunctions that occur when there is a loss The participants of the workshop VI Preface of the hormone or the receptor activity. Loss of estrogen, however (for instance during menopause), occurs with time and results in a variety of clinical conditions. We know that the developmental loss of estrogen, as seen in clinical cases of aromatase gene mutations and experimental models, has dramatic effects in both men and women alike. The evidence that these effects are mediated through the estrogen receptor(s) is based on similar but not always identical phenotypes as observed in experimental animal models of estrogen receptor mutations as well as the single clinical case of an estrogen receptor alpha mutant patient. Developing an understanding of the spectrum of estrogen in a variety of tissues related to the condition of estrogen loss is a major and highly active clinical as well as basic scientific research area. Following the discovery of a second estrogen receptor and possible receptor ligand-independent activity as well as the genomic and non genomic actions of estrogen, it is clear that the mechanisms of the effects of estrogen are multifaceted.

Download or read book Mechanisms of Aryl Hydrocarbon Receptor and Estrogen Receptor Action in Breast Cancer Cells written by Jeong Eun Lee and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In MCF7 and T47D cells cotreated with 1 nM 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) plus 0.1-10 uM 3̕,4̕ -dimethoxy flavone (DMF), there was a concentration-dependent decrease in the TCDD-induced ethoxyresorufin O-deethylase (EROD) activity. Gel mobility shift assays showed that 3̕,4̕ -DMF inhibited TCDD-induced aryl hydrocarbon receptor (AhR) transformation in rat liver cytosol and blocked TCDD-induced formation of the nuclear AhR complex in MCF7 and T47D cells. The antiestrogenic activity of TCDD in estrogen-induced transactivation assays in MCF7 cells was reversed by 3̕,4̕ -DMF, confirming the AhR antagonist activity of this compound in breast cancer cells. Cotreatment of T47D and MCF7 cells with TCDD and 10 uM resveratrol inhibited induction of CYP1A1 mRNA and EROD activity. Resveratrol did not inhibit TCDD-induced AhR transformation and reporter gene activity. Actinomycin D chase experiments in T47D cells showed that the mechanism of inhibition of CYP1A1 mRNA and EROD activity is due to an increased rate of CYP1A1 mRNA degradation, suggesting that resveratrol inhibits CYP1A1 via an AhR-independent post-transcriptional pathway. Vitamin D receptor-interacting protein 150 (DRIP150) coactivated estrogen receptor [alpha] (ER [alpha])-mediated transactivation and the response was AF2-dependent in ZR75 breast cancer cells. C-and N-terminal NR-boxes (amino acids 1186-1182 and 73-69, respectively) were not necessary for coactivation of ER [alpha]. Analysis of DRIP150 deletion mutants identified a 23 amino acid sequence (811-789) required for coactivation. The 23 amino acid contained two regions at amino acids 789-794 and 795-804 which resembled [alpha] -helical motifs identified in Lanuguinosa lipase/histamine N-methyl transferase and hepatocyte nuclear factor 1, respectively. A squelching assay using specific point mutations within each [alpha] -helix showed that the NIFSEVRVYN (795-804) region was the critical sequence required for the coactivator activity of DRIP150.

This book was released on 2007 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: ERá is a critical regulator in breast cancer and mammary gland development. Deregulation of ER signaling correlates with abnormal mammary gland development and breast cancer. However, the role of epithelial ER remains to be clarified in vivo and the mechanism of ER signaling regulation is far from comprehensive. We hypothesize that 1) mammary epithelial ER plays critical roles in mammary gland development during pregnancy and lactation and that 2) novel, as yet identified factors in ER transcriptional regulation are involved in breast cancer development. The loxP-Cre system was used to generate epithelial ERKO mice. The well characterized MMTV-Cre and WAP-Cre transgenic mice were used to delete ER in mammary epithelial cells at different developmental stages. Early expression of MMTV-Cre arrested mammary gland development at the neonatal stage. Successive pregnancy and lactation activated epithelial ER ablation, which compromised side-branching, alveolar development, and epithelial proliferation. Further analysis revealed a massive loss of luminal epithelial cells presumably caused by apoptosis. The abnormal mammary gland development decreased milk production, thereby, caused growth retardation in the offspring. Similar phenotypes were also observed in MMTV-ERKO females in lactation. Thus, we concluded that epithelial ER is essential for mammary gland development during pregnancy and lactation stages. To further pursue the molecular mechanism of ER signaling regulation, a human mammary gland cDNA library was screened to identify novel factors that interact with ER. One novel ERá binding protein identified in the screen contains two conserved LXXLL motifs (NR-box) and a coiled-coil domain. The protein product, which we named NRCC, consists of 3 isoforms that vary in their N-terminal region. NRCC is conserved in vertebrates and its mRNA was detected in human breast cancer cells and mouse breast tumors. We found that NRCC-A interacts with ERá and enhances ERá transcriptional activity in human cancer cells. Moreover, NRCC-A co-localized with ERá in the cell nucleus and was recruited to ER target gene promoters. SiRNA analysis indicated that NRCC proteins are important for endogenous ERá-mediated transcriptional activity and estrogen dependent cell proliferation. Taken together, these data indicate that NRCC-A is a novel coactivator for ERá.

Available in PDF, EPUB and Kindle. Book excerpt: Estrogen plays a critical role in the development and progression of breast cancer. While endocrine therapies play an important part in breast cancer treatment, the failure of these therapies reflects a lack of knowledge concerning the molecular mechanisms involved in estrogen signaling. The biological activities of estrogen are mediated by estrogen receptors (ER) . In addition, a large number of proteins termed cofactors are involved in ER signaling. Until recently, our knowledge regarding these cofactors was based on their ability to bind receptors in vitro and affect transcriptional activation in transfection experiments. The in vivo role of these cofactors and the specific target genes involved in breast cancer are not well known. Therapeutic agents, such as tamoxifen, also bind ER, but block proliferation in breast cells. However, tamoxifen increases the risk of endometrial cancer. We have used chromatin immunoprecipitation (ChIP) to investigate cofactor involvement in ER signaling in vivo and to understand the mechanisms underlying the different actions of tamoxifen in breast and endometrial cells. We are in the process of using ChIP to identify the set of genes regulated by ER and its cofactors in these tissues. The detailed understanding of tissue- and ligand-dependent changes in gene expression gained through these studies will lead to more effective therapies for ER-dependent breast cancer.

This book was released on 2012-12-06 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Breast Cancer: Cellular and Molecular Biology [Kluwer Academic Pub lishers, 1988], we tried to present an introduction to the emerging basic studies on steroid receptors, oncogenes, and growth factors in the regulation of normal and malignant mammary epithelium. The response to this volume was superb, indicating a tremendous interest in basic growth regulatory mechanisms governing breast cancer and controlling its malignant progres sion. In the two years since its publication, much new and exciting in formation has been published and the full interplay of regulatory mechanisms is now beginning to emerge. We have divided this book into four sections that we hope will unify important concepts and help to crystallize areas of consensus and/or disagreement among a diverse group of basic and clinical scientists working on the disease. The first section is devoted to studies on oncogenes, antioncogenes, proliferation, and tumor prognosis. The first chapter, by Sunderland and McGuire, introduces the characteristics of breast cancer as studied by patho logists to establish prognostic outcome. Of particular interest is a new proto oncogene called HER-2 (or neu), which is rapidly becoming accepted as a valuable new tumor marker of poor prognosis. The second chapter, by Lee Bookstein and Lee, introduces the best known antioncogene, the retinoblas toma antioncogene, whose expression is sometimes lost in breast cancer. Malignant progression appears to be influenced by the balance of proto oncogene and antioncogene expression.

Available in PDF, EPUB and Kindle. Book excerpt: Estrogen receptors (ERs) are typical members of the superfamily of nuclear receptors that mainly function as ligand-inducible transcription factors that bind chromatin, as homodimers, at specific response elements. A tight reciprocal coupling between rapid 'non-genomic' and 'genomic' ER actions may also occur in many physiological processes. ERs have long been evaluated for their roles in controlling the expression of genes involved in vital cellular processes such as proliferation, apoptosis, and differentiation. Therefore, given the various and pleiotropic functions of ERs, the dysregulation of their pathways contributes to several diseases such as the hormone-dependent breast; endometrial and ovarian cancers; and neurodegenerative diseases, cardiovascular diseases, and osteoporosis. In this printed edition of the Special Issue, "Molecular Pathways of Estrogen Receptor Action," promising results on understanding the mechanisms underlying ER-mediated effects in various pathophysiological processes are represented, covering different roles of ER pathways in the tumorigenesis, the resistance to endocrine therapy, the dynamics of 3D genome organization, and cross-talk with other signaling pathways. This Special Issue also provides insight into the emerging roles of estrogen-signaling pathways in lung cancer, the tumor microenvironment, and the immune system.]

Book excerpt: Oestrogen receptors (ER) are emerging as important molecules involved in the variety of physiological and pathological activities. There are two classic oestrogen receptors: alpha and beta. Different cells and tissues have shown divergent responses to these two oestrogen receptors. While we are starting to understand the interaction between oestrogen receptors and its ligands contributes to the development of various diseases, the discovery of sub-isoforms of oestrogen receptor alpha and beta has further complicated the mechanism of oestrogen receptors. Nevertheless, continuing efforts in the study of oestrogen receptors have helped us to define their roles in diseases and to develop novel therapies against these disorders. The 11 chapters in this book are the excellent evidence to summarise our efforts in this direction. This book should be of great value to not only clinicians and medical students interested in oestrogen/ER-related diseases but also basic scientists working in the field of estrogens/ERs.
