Big renin and biosynthetic defect of aldosterone in diabetes mellitus

Abstract

To determine the cause of selective aldosterone deficiency in two patients with diabetes mellitus, studies of renin and of aldosterone-precursor metabolites were performed under conditions of sodium depletion and ACTH stimulation. Plasma renin concentration was elevated in both patients, and stimulated plasma renin activity was low in one and normal in the other. Fractionation of plasma extracts demonstrated the presence of "big renin," a relatively inactive precursor of renin. Metabolites of aldosterone precursors were increased, suggesting deficient 18-hydroxylase in one patient and dehydrogenase in the other. The results suggest that hypoaldosteronism in diabetic patients may result from combined defects in both renin and aldosterone biosynthesis.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
