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...

Relaxin-3 (INSL-7) is a recently discovered member of the insulin superfamily, a group of structurally related hormones whose precursors have a domain arrangement similar to that of pro-insulin. Relaxin-3 mRNA is expressed in the nucleus incertus of the brainstem which has projections to the hypothalamus, an area important in appetite regulation. Relaxin-3 binds with high affinity to the recently discovered previously orphan G-protein-coupled receptor, GPCR135, which is expres...

Some people with obesity have hormonal, metabolic and circulatory changes that constitute the metabolic syndrome that resemble characteristics of patients with Cushing's syndrome. A link between the two conditions, possibly genetic, has therefore been suspected, and the glucocorticoid receptor gene (GRL, 5q31-q32) has been one of the candidate genes.The single nucleotide polymorphism N363S is an ATT to GTT missense alteration within exon 2 of G...
