(Submitter supplied) Whereas estrogens exert their effects by binding to nuclear estrogen receptors and directly altering target gene transcription, they can also initiate extranuclear signaling through activation of kinase cascades. We have investigated the impact of estrogen-mediated extranuclear initiated pathways on global gene expression by using estrpgen-dendrimer conjugates. Keywords: ligand treatment

(Submitter supplied) The nuclear hormone receptor, estrogen receptor-alpha (ERα), and MAP kinases both play key roles in hormone-dependent cancers, yet their interplay and the integration of their signaling inputs remain poorly understood. In these studies, we document that estrogen-occupied ERα activates and interacts with ERK2, a downstream effector in the MAPK pathway, resulting in ERK2 and ERα colocalization at chromatin binding sites across the genome of breast cancer cells. more...

Analysis of MCF7 cells depleted of ERK1 or ERK2 and treated with estradiol for up to 24hrs. ERK1 and ERK2 are downstream effectors in the MAP kinase pathway; estrogen receptor α (ERα) and MAPKs play key roles in hormone-dependent cancers. Results provide insight into ERα and MAPK interactions.

(Submitter supplied) Poly (ADP-ribose) polymerase-1 (PARP-1), a multifunctional chromatin-modulating protein, has gained considerable attention as a target for therapeutic inhibitors in breast cancers. Accumulating evidence suggests a pathological role for PARP-1 in breast cancer through its effects on the transcription of tumor-related genes. Here we report the role of PARP-1 in estrogen-dependent transcription in estrogen receptor alpha (ERα)-positive breast cancers. more...

(Submitter supplied) The PARP family of proteins comprises 17 members, about two thirds of which are active mono- or poly(ADP-ribosyl)transferase enzymes that transfer the ADP-ribose moiety of NAD+ onto target proteins. In many cases, ADP-ribosylation, which plays critical roles in human diseases (e.g., cancer, heart disease, and neuropathies) is associated with abrogation of the molecular functions of the target. Discerning ADP-ribosylation events mediated by a specific PARP is challenging, since all PARPs use the same substrate (i.e., NAD+) and the available inhibitors lack the specificity needed to make such conclusions. more...

(Submitter supplied) In addition to the estrogen responsive element (ERE)-dependent gene expression, E2-ERbeta regulates transcription through functional interactions with transfactors bound to their cognate regulatory elements on DNA, hence the ERE-independent signaling pathway. However, the relative importance of the ERE-independent pathway in E2-ERbeta signaling is unclear. Our studies in infected ER-negative cell models with an ERbeta mutant (ERbetaDBD) that functions exclusively at the ERE-independent pathway demonstrated that genomic responses assessed by microarrays from the ERE-independent pathway to E2-ERbeta are not sufficient to alter cellular growth, death or motility. more...

(Submitter supplied) We were interested in determining what genes might be controlled by TFAP2C and/or TFAP2A, either directly or indirectly through regulation of ER-alpha and potentially other signaling pathways. We performed an microarray analysis in MCF7 cells with elimination of either TFAP2C or TFAP2A. The patterns of gene expression with alteration of TFAP2 activity were compared to changes in expression induced by estrogen exposure. more...

(Submitter supplied) Cancer cell motility and invasiveness are fundamental characteristics of the malignant phenotype and are regulated through diverse signaling networks involving kinases and transcription factors. In this study, we identify a nuclear hormone receptor (ERα)-protein kinase (ERK5)-cofilin (CFL1) network that specifies the degree of breast cancer cell aggressiveness through coupling of actin reorganization and hormone receptor-mediated transcription. more...

(Submitter supplied) Enhancers are genomic regulatory elements shown to play key roles in controlling cell type-specific gene expression, regulated by signal-dependent transcription factors and co-factors. Distinct classes of enhancers can specify distinct gene expression profiles and biological outcomes. Recent studies suggested that bidirectional non-coding RNAs (ncRNAs), referred as enhancer RNA (eRNAs), are transcribed on enhancers, which are tightly associated with enhancer activity. more...
