Primary Research Papers
Korbonits M. et al (2004) Ghrelin—a hormone with multiple functions. Frontiers in Neuroendocrinology 25:27-68 (In the current review we comprehensively summarize (i) the data available regarding the structure, expression pattern and regulation of ghrelin and its receptor; (ii) the available information regarding the effect of ghrelin on the pituitary hormone axis, appetite regulation, cardiac and gastrointestinal function, carbohydrate metabolism, adipose and reproductive tissue, cell proliferation and behavioral effects; (iii) experimental and clinical data regarding circulating ghrelin levels observed in various physiological and pathological conditions; and (iv) data on gene variations of ghrelin and its receptor.)
