We have previously shown that the ACTH precursor, POMC, is present in human plasma and is the predominant secreted POMC peptide. This suggests that POMC processing is incomplete in neuroendocrine cells and regulation of the post-translational cleavage pathway is important in controlling secretion of ACTH. We have therefore analysed the dynamics of POMC processing in both AtT20 pituitary adenoma cells and primary rat pituitary cells. In both cases, large quantities of POMC, as ...

Low IGFBP2 is associated with the metabolic syndrome, but high IGFBP2 is longitudinally associated with worsening renal function. IGFBP2 binds IGF2 (and IGF1) and modified IGF bioavailablilty. The aim of our study was to identify whether baseline IGFBP2 concentrations were associated with all-cause and cardiovascular mortality in type 2 diabetes.554 subjects (59.3% male, mean age 63.7 (S.D. 10.7)) with type 2 diabetes from the Salford Diab...
