dcterms.abstractLes récepteurs nucléaires sont des facteurs transcriptionnels impliqués dans la regulation de la croissance cellulaire, en partie dû à leurs effets génomiques. Une voie alternative est l'interference entre les récepteurs nucléaires et le facteur transcriptionnel AP-1 (activator protein-1), composé de protéines induites par plusieurs facteurs de croissance et molécules de signalisation. Dans ce projet, j'ai analysé les mécanismes d'interférence transcriptionnelle entre les récepteurs des oestrogènes (ER), les récepteurs des glucocorticoïdes (GR) et AP-1.fr
dcterms.abstractNuclear receptors constitute a large superfamily of DNA binding transcriptional regulators that can regulate a diversity of important cellular events, such as development, differentiation, and responses to extracellular stimuli. These effects are mediated mostly by the genomic effects of nuclear receptors which bind selectively to DNA (hormone response element), and regulate target gene transcription. An alternative pathway of transcriptional regulation is the crosstalk between nuclear receptors and other transcription factors, such as NPKB, or activator protein-1 (AP-1). Transcription factor AP-1 is composed of nuclear proteins encoded by the Jun family and Fos family of protooncogenes, whose transcription is rapidly induced by a number of growth factors and other signaling molecules. AP-1 is implicated in diverse aspects of cell growth, differentiation and development. In this project, I have focused on the analysis of the mechanisms of transcriptional interference between nuclear receptors and AP-1.fr
