Renin-angiotensin system and unilateral ureteral obstruction
Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...
متن کاملAging and the renin-angiotensin system.
A ngiotensin II (Ang II), the dominant effector molecule of the renin-angiotensin system (RAS), exerts its effects on binding of 2 pharmacologically distinct rhodopsin-like G protein–associated receptors, the type 1 and the type 2 (AT 1 and AT 2) receptors. 1 Human cells express a single AT 1 receptor, whereas 2 isoforms, AT 1A and AT 1B with 95% of amino acid sequence identity and similar affi...
متن کاملThe Renin-Angiotensin System and Aging
Dr Lewis K. Dahl identified many of the relationships that underlie our current thinking and focus of research on hypertension. Among the first to establish the interactions between salt and hypertension, the realization that genetic factors played a major role in how the kidney responded to salt loads led to development of the genetically predisposed Dahl salt-sensitive rat. His research, alth...
متن کاملThe renin-angiotensin system and aging in the kidney
Aging is associated with progressive functional deterioration and structural changes in the kidney. Changes in the activity or responsiveness of the renin-angiotensin system (RAS) occur with aging. RAS changes predispose the elderly to various fluid and electrolyte imbalances as well as acute kidney injury and chronic kidney disease. Among the multiple pathways involved in renal aging, the RAS ...
متن کاملThe intracrine renin-angiotensin system.
The RAS (renin-angiotensin system) is one of the earliest and most extensively studied hormonal systems. The RAS is an atypical hormonal system in several ways. The major bioactive peptide of the system, AngII (angiotensin II), is neither synthesized in nor targets one specific organ. New research has identified additional peptides with important physiological and pathological roles. More pepti...
