Primary aldosteronism (PA) is the most frequent form of secondary hypertension and is due to autonomous aldosterone production by the adrenal gland. During the last decades, major advances have been made in our understanding of the disease with the identification of germline or somatic mutations in ion channels and pumps. These mutations enhance calcium signaling, the main trigger of aldosterone biosynthesis. The objective of our work was to elucidate, using chemogenetic tools...

Introduction: Primary aldosteronism (PA) is the most frequent form of secondary hypertension. Over the past 10 years, important discoveries have been made regarding the genetic basis of aldosterone producing adenoma and familial forms of primary aldosteronism. In most cases, genetic abnormalities are found in genes coding for ion channels (KCNJ5, CACNA1D, CACNA1H, CLCN2) and pumps (ATP1A1, ATP2B3). These mutations affect intracellular ion homeostasis and/or c...

Background: A normal islet includes both mature and immature β-cells, with the former possessing higher insulin content and the latter displaying better proliferative capacity. However, it remains unknown whether immature β-cells also contribute to the regulation of insulin release, especially by commanding the activity of their mature counterparts.Materials and methods: Pdx1, Mafa, and Ngn3 were overexpressed in &#94...
