Ghrelin is stored alongside glucagon in developing islet, although in a discrete cellular compartment, the pancreatic ε-cell. However, recent observations have shown a subpopulation of ghrelin/glucagon-double-positive cells in developing pancreas. The aim of the present study was to examine the developmental patterns of ghrelin- and glucagon-immunoreactive (ir) cells expression and possible co-localization of these hormones during human pancreas development. For this purp...

The co-secretion of GHRH and GH has been described previously in a patient with GHRH producing pituitary somatotroph adenoma. Here we present a patient with MEN1 and ectopic secretion of both GHRH and GH from a neuroendocrine lung tumor.A 52-year-old woman was diagnosed in 2009 with two lung tumors, 4 cm right upper lobe tumor, and 2 cm left lower lobe tumor. Owing to a mild coarsening of facial features, acromegaly was suspected. Endocrine studies showe...
