AIMS/HYPOTHESIS Upregulation of the functional beta cell mass is required to match the physiological demands of mother and fetus during pregnancy. This increase is dependent on placental lactogens (PLs) and prolactin receptors, but the mechanisms underlying these events are only partially understood. We studied the mRNA expression profile of mouse islets(More)
AIMS/HYPOTHESIS Pregnancy requires an increase in the functional beta cell mass to match metabolic needs for insulin. To understand this adaptation at the molecular level, we undertook a time course analysis of mRNA expression in mice. METHODS Total RNA extracted from C57Bl6/J mouse islets every 3 days during pregnancy was hybridised on commercially(More)
W hat makes b-cells unique is their continuous responsibility to produce, store and release the required amount of insulin to keep blood glucose normal. This is no trivial task because daily insulin demands fluctuate acutely (as happens during meals) or chronically (e.g., the adaptation to obesity or pregnancy). Moreover, normal blood glucose has two(More)
The Nestin-Cre driver mouse line has mild hypopituitarism, reduced body weight, a metabolic phenotype and reduced anxiety. Although several causes have been suggested, a comprehensive explanation is still lacking. In this study we examined the molecular mechanisms leading to this compound phenotype. Upon generation of the Nestin-Cre mice, the human growth(More)
