Cushing’s syndrome and chronotype

Albani Adriana , Zopp Stephanie , Simon Julia , Vogel Frederick , Reincke Martin , Merrow Martha , Theodoropoulou Marily

Patients with Cushing’s syndrome have a poor quality of sleep. However, little is known about their timing of sleep as regulated by the circadian clock, the so called-chronotype. Considering that patients with Cushing’s syndrome lose their rhythmic circadian cortisol secretion and that corticosteroids act as synchronizer of the circadian clock in cells, aim of the study was to determine whether patients with Cushing’s syndrome alter the timing of their sleep com...

IntroductionIntegrins are heterodimeric transmembrane proteins composed of alpha and beta subunits that mediate cell-cell and cell-extracellular matrix (ECM) interactions. Several integrins are overexpressed in human cancers and their ECM recognition motif, arginine-glycine-aspartate (RGD), is being utilized for tumour imaging and targeting.AimTo explore the expression and function of RGD-binding integrins in...

IntroductionTP53 mutations have been rarely reported in pituitary tumours. Recently two exploratory exome sequencing studies have identified somatic TP53 mutations in a small number of functional corticotroph tumours (6/18 and 4/10) with USP8 wild type (wt) status, suggesting that they may be more frequent than previously thought. Nevertheless, the clinical impact of those mutations is still unknown.AimTo det...
