Adipocytes have a key role in obesity and precursor cells can differentiate into white or brown adipocytes, with different metabolic functions. However the process by which stem cells commit to these lineages, and the factors that distinguish white adipogenesis from brown, are poorly understood.Fetal mesenchymal stem cells (fMSCs) can differentiate into adipocytes, but neither the regulation of this process, nor the phenotype differentiated cells has bee...

Nuclear receptors control developmental and physiological processes by regulating the transcription of gene networks in specific cells. This is achieved by the recruitment of coactivators and corepressors that lead to chromatin remodelling and alterations in gene transcription. RIP140 is a ligand dependant corepressor for nuclear receptors that plays key roles in adipose tissue and muscle to regulate energy homeostasis.RIP140 regulates carbohydrate and l...

Nuclear receptors regulate biological responses by acting as ligand dependent transcription factors in target cells. Their ability to modulate transcription is mediated by cofactors which are recruited to target genes by binding to receptors. They can either act as coactivators or corepressors and their roles include their ability to remodel chromatin and to recruit the basic transcription machinery. NRIP1 is transcriptional repressor which is recruited to nuclear receptors in...

Nuclear Receptors control many developmental and physiological processes by regulating the expression of networks of genes. Their ability to activate or repress gene transcription depends on the recruitment of coactivators and corepressors that function as scaffolds for the binding of chromatin remodelling enzymes. RIP140 is a ligand dependant corepressor for most, if not all, nuclear receptors with key roles in energy homeostasis and reproduction.RIP140...
