Key result
Nephron-specific deletion of the prorenin receptor in mice caused a urine concentration defect with significantly lower urine osmolality, higher water intake, and higher urine volume.

Does nephron-specific deletion of the prorenin receptor alter renal water excretion in mice?
p-value: p=<0.05
Nephron-specific deletion of the prorenin receptor in adult mice causes a urine concentration defect, suggesting that the PRR modulates renal water excretion via AVP responsiveness.
Ramkumar et al. (2015) studied Urine concentration defect. Nephron-specific prorenin receptor (PRR) deletion vs. Control mice was evaluated on Urine osmolality, water intake, and urine volume (p=<0.05). Nephron-specific deletion of the prorenin receptor in mice caused a urine concentration defect with significantly lower urine osmolality, higher water intake, and higher urine volume.
