Adrenocortical carcinoma (ACC) is an orphan tumor entity the pathogenesis of which is poorly understood. In advanced tumour stages, prognosis is unfavorable, but biomarkers for early diagnosis are lacking. MALDI-Mass Spectrometry Imaging (MALDI-MSI) enables semi-quantitative detection of a broad spectrum of analytes including endogenous cell metabolites in tissue sections. MALDI-MSI was used as a discovery approach to analyse tissue specimens of 72 ACC patients in FFPE tissue ...

Background: Sporadic aldosterone-producing adenomas (APA) are relevant cause of endocrine related hypertension in Primary Aldosteronism (PA). Next generation sequencing techniques have identified somatic mutations in APA harbored in KCNJ5, ATP1A1, ATP2B3, CACNA1D, CTNNB1 and PRKACA genes. Yet, a number of APA harbor no mutations in candidate genes (designated as wild type, WT) and little is known about genotype/phenotype correlation.Objectives: We invest...
