Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [4] [5] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [6]
The outermost layer, the zona glomerulosa is the main site for the production of aldosterone, a mineralocorticoid. The synthesis and secretion of aldosterone are mainly regulated by the renin–angiotensin–aldosterone system. The zona glomerulosa cells express a specific enzyme aldosterone synthase (also known as CYP11B2).
5-DHT or DHT is a male reproductive hormone that targets the prostate gland, bulbourethral gland, seminal vesicles, penis and scrotum and promotes growth/mitosis/cell maturation and differentiation. Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of ...
Sodium retention is also a response of the distal colon and sweat glands to aldosterone receptor stimulation. Angiotensin II and extracellular potassium are the two main regulators of aldosterone production. [19] The amount of sodium present in the body affects the extracellular volume, which in turn influences blood pressure. Therefore, the ...
The enzyme aldosterone synthase (also known as CYP11B2) acts in this location [3] [4] The expression of neuron-specific proteins in the zona glomerulosa cells of human adrenocortical tissues has been predicted and reported by several authors [5] [6] [7] and it was suggested that the expression of proteins like the neuronal cell adhesion ...
The immune system specifically targets the cells of the adrenal cortex and destroys them, but Addison's disease can also be caused by a severe infection such as tuberculosis. Some symptoms include hypoglycemia and decreased blood sodium levels and increased blood potassium levels caused by a deficiency of aldosterone. These electrolyte ...
Anatomical diagram of RAS [1] The renin-angiotensin system (RAS), or renin-angiotensin-aldosterone system (RAAS), is a hormone system that regulates blood pressure, fluid, and electrolyte balance, and systemic vascular resistance. [2] [3]
Aldosterone synthase, also called steroid 18-hydroxylase, corticosterone 18-monooxygenase or P450C18, is a steroid hydroxylase cytochrome P450 enzyme involved in the biosynthesis of the mineralocorticoid aldosterone and other steroids. The enzyme catalyzes sequential hydroxylations of the steroid angular methyl group at C18 after initial 11β ...
