Luminal lncRNAs Regulation by ERα-Controlled Enhancers in a Ligand-Independent Manner in Breast Cancer Cells
Estrogen receptor-α (ERα) is a ligand-inducible protein which mediates estrogenic hormones signaling and defines the luminal BC phenotype. Recently, we demonstrated that even in absence of ligands ERα (apoERα) binds chromatin sites where it regulates transcription of several protein-coding and lncRNA genes. Noteworthy, apoERα-regulated lncRNAs marginally overlap estrogen-induced transcripts, th...
متن کاملThermodynamic models of combinatorial gene regulation by distant enhancers.
The dynamical properties of distal and proximal gene regulatory elements are crucial to their functionality in gene regulatory networks. However, the multiplicity of regulatory interactions at control elements makes their theoretical and experimental characterisation difficult. Here a thermodynamic framework to describe gene regulation by distant enhancers via a chromatin mechanism is developed...
متن کاملLigand-dependent receptor down-regulation
The kinetics of internalization, sequestration and metabolic degradation of atrial natriuretic factor (ANF)-receptor complex were studied in rat thoracic aortic smooth-muscle (RTASM) cells. These parameters were directly determined by measuring 125I-ANF binding to total, intracellular and cell-surface receptors. Pretreatment of cells with the lysosomotropic agent chloroquine and the energy depl...
متن کاملGene regulation by voltage-dependent calcium channels.
Ca2+ is the most widely used second messenger in cell biology and fulfills a plethora of essential cell functions. One of the most exciting findings of the last decades was the involvement of Ca2+ in the regulation of long-term cell adaptation through its ability to control gene expression. This finding provided a link between cell excitation and gene expression. In this review, we chose to foc...
متن کاملDETECTION OF GENE ENHANCERS BY Drosophila ENHANCER TRAP ANALYSIS Enhancers: Transcriptional enhancers are DNA sequences
Enhancers: Transcriptional enhancers are DNA sequences that control expression of nearby genes and direct tissue-specific, positive regulation of those genes (Karp, 2002; Griffiths, et al., 2002). The general mode of action of these sequences is that they associate with specific activator proteins (that are found in only certain tissues); this association of enhancer and activator facilitates t...
