Renin-Angiotensin System Induced Secondary Hypertension: The Alteration of Kidney Function and Structure
Table 1
RAS receptor distribution change in response to hypertension. AT1R distribution change related to time after 2K1C or 2K1W in hypertensive rat models.
Major RAS receptors
Hypertension
AT1 receptor
Aorta AT1R expression Vascular and glomerular AT1R downregulation Proximal tubular receptors upregulation or not significantly altered
AT1 receptor alteration after 2K1C or 2K1W in hypertensive rat models
Time after clipping
1 week
AT1R mRNA in the clipped, wrapped, and contralateral kidneys
10 days
AT1AR protein in clipped and unclipped kidneys
2 weeks
Glomerular AT1R
10 weeks
AT1R mRNA levels in clipped and unclipped kidneys
16 weeks
Vascular AT1R
AT2 receptor
Aorta AT2R expression unchanged Sodium depletion & SHR AT2R expression AT2R downregulation only in clipped and wrapped kidneys, in 2K1C and 2K1W
Mas receptor
Carotid MasR protein expression in 2K1C rats MasR in proximal tubules of clipped kidney in male rats MasR in clipped and unclipped kidney of female rats
