Due to its rapid development and high fecundity, the zebrafish is a standard model in developmental biology and genetics. Furthermore, key hormone systems present in mammals are already active in zebrafish larvae. The endocrine system and the circadian clock are closely linked, and also the circadian system of zebrafish matures early in development. The small size of zebrafish larvae makes them particularly suitable for chemical screens in vivo: Larvae can be kept for...

Diurnal cortisol delivery: a novel tool for adrenal insufficiency

Ross Richard

Cortisol is an essential stress hormone and replacement with oral hydrocortisone is lifesaving in patients with adrenal insufficiency. Cortisol has a diurnal rhythm regulated by the central body clock and this rhythm is a metabolic signal for peripheral tissue clocks. Loss of cortisol rhythmicity is associated with fatigue, depression and insulin resistance. A general principle in endocrinology is to replace hormones to replicate physiological concentrations; however the pharm...
