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 receptorsHypertension
AT1 receptorAorta 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 modelsTime after clipping
1 weekAT1R mRNA in the clipped, wrapped, and contralateral kidneys
10 daysAT1AR protein in clipped and unclipped kidneys
2 weeksGlomerular AT1R
10 weeksAT1R mRNA levels in clipped and unclipped kidneys
16 weeksVascular AT1R
AT2 receptorAorta AT2R expression unchanged
Sodium depletion & SHR AT2R expression
AT2R downregulation only in clipped and wrapped kidneys, in 2K1C and 2K1W
Mas receptorCarotid 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
