Growth factors and apoptosis in neonatal ureteral obstruction.
Renal insufficiency as a result of congenital obstructive nephropathy is a consequence of impaired renal growth: chronic unilateral ureteral obstruction (UUO) results in greater injury to the immature kidney than to the adult kidney. The neonatal kidney responds to UUO by marked activation of the renin-angiotensin system, which contributes to severe vasoconstriction and progressive interstitial...
متن کاملRenin-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 کاملRenal apoptosis parallels ceramide content after prolonged ureteral obstruction in the neonatal rat.
Obstructive nephropathy, the primary cause of renal insufficiency in infants, is characterized by progressive renal apoptosis. Ceramide is a sphingolipid known to stimulate apoptosis in the kidney. We investigated the effects of unilateral ureteral obstruction (UUO) on endogenous renal ceramide content and apoptosis in neonatal and adult rats. Animals were subjected to UUO or sham operation on ...
متن کاملCompensatory renal growth after unilateral ureteral obstruction.
Compensatory renal growth after unilateral ureteral obstruction. The accumulation of bulk renal protein, RNA and DNA was studied in mice during a 35-day period of accelerated renal growth in the kidney contralateral to that obstructed by acute ureteral ligation. Control mice were sham-operated and nonoperated. RNA was determined by the method of Monroe and Fleck, DNA after Ceriotti and protein ...
متن کاملEarly release of neonatal ureteral obstruction preserves renal function.
The incidence of congenital hydronephrosis is approximately 1% and is often associated with renal insufficiency. It is unknown whether early release is essential to prevent deterioration of renal function. Rats were subjected to partial unilateral ureteral obstruction (PUUO) on postnatal day 2. The obstruction was left in place or released after 1 or 4 wk. Renal blood flow (RBF) and kidney size...
