Muscle RAS oncogene homolog

MRAs, R-Ras3
This gene encodes a member of the Ras family of small GTPases. These membrane-associated proteins function as signal transducers in multiple processes including cell growth and differentiation, and dysregulation of Ras signaling has been associated with many types of cancer. The encoded protein may play a role in the tumor necrosis factor-alpha and MAP kinase signaling pathways. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011] (from NCBI)

Catena et al., Udine, Italy. In Horm Metab Res, Dec 2015
Treatment with mineralocorticoid receptor antagonists (MRAs) is currently recommended for PA patients with bilateral adrenal disease, but these agents effectively decrease blood pressure also in patients with unilateral disease, although concern remains for possible sex-related side effects.

Rossignol et al., Vandœuvre-lès-Nancy, France. In Clin Res Cardiol, Dec 2015
Mineralocorticoid receptor antagonists (MRAs) in natriuretic doses may improve spot urine sodium excretion and outcomes.
Comparison of eplerenone and spironolactone for the treatment of primary aldosteronism.
Takeda et al., Kanazawa, Japan. In Hypertens Res, Dec 2015
Fifty-four patients with PA were treated with one of two MRAs, EPL (25-100 mg daily, n=27) or SPL (12.5-100 mg daily, n=27) for 12 months.
General practitioners' adherence to chronic heart failure guidelines regarding medication: the GP-HF study.
Eschenhagen et al., Hamburg, Germany. In Clin Res Cardiol, Dec 2015
In Stage I, 206 patient records from 15 randomly chosen GP practices were analysed; 76 % of patients were prescribed ACE-inhibitors or angiotensin receptor blockers (ACEIs/ARBs), 73 % beta blocker (BBs), but only 18 % mineralocorticoid receptor antagonists (MRAs).
Molecular mechanisms of skeletal muscle development, regeneration, and osteogenic conversion.
Endo, Chiba, Japan. In Bone, Nov 2015
The small GTPase M-Ras is likely to participate in the ectopic calcification and ossification, as well as in osteogenesis during development.

Tesch et al., Australia. In Plos One, 2014
BACKGROUND/AIM: Steroidal mineralocorticoid receptor antagonists (MRAs) are effective in the treatment of kidney disease; however, the side effect of hyperkalaemia, particularly in the context of renal impairment, is a major limitation to their clinical use.
