The mineralocorticoid receptor (or MR, MLR, MCR), also known as the aldosterone receptor or nuclear receptor subfamily 3, group C, member 2, (NR3C2) is a protein that in humans is encoded by the NR3C2 gene that is located on chromosome 4q31.1-31.2. [5] MR is a receptor with equal affinity for mineralocorticoids and glucocorticoids.
The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral. The primary endogenous mineralocorticoid is aldosterone , although a number of other endogenous hormones (including progesterone [ 1 ] and deoxycorticosterone ) have mineralocorticoid function.
Membrane mineralocorticoid receptors (mMRs) or membrane aldosterone receptors are a group of receptors which bind and are activated by mineralocorticoids such as aldosterone. [ 1 ] [ 2 ] Unlike the classical nuclear mineralocorticoid receptor (MR), which mediates its effects via genomic mechanisms, mMRs are cell surface receptors which rapidly ...
Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
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).
Pandy's test (or Pandy's reaction) is done on the CSF (cerebrospinal fluid) to detect the elevated levels of proteins (mainly globulins). This test is named after the Hungarian neurologist , Pándy Kálmán (1868–1945) who developed this test in the year 1910.
Licorice, which contains glycyrrhizinic acid and enoxolone, can inhibit HSD-11β and lead to the apparent mineralocorticoid excess syndrome. Cortisol levels consequently rise, and cortisol binding to the mineralocorticoid receptor produces clinical signs and symptoms of hypokalemia, alkalosis and hypertension (i.e., mineralocorticoid excess).
Furthermore, in this procedure, the materials are placed into round wells in the gel's core part and disperse through it, generating a deposition ring with a diameter relation to the number of unbound protein that has diffused.
