Macromolecular Metabolism in Compensatory Renal Hypertrophy
1. The initial biochemical changes of compensatory hypertrophy occur well within 1 hour of unilateral nephrectomy and perhaps within the first few minutes.2. The initial increment in rRNA is from decreased metabolism rather than from increased synthesis.3. Changes in the processing of mRNA precursors are probably also important.4. Compensatory hypertrophy is regulated by a humoral stimulus or s...
متن کاملPhospholipid metabolism in the initiation of renal compensatory growth after acute reduction of renal mass.
Membrane metabolism was studied during the initiation of compensatory growth after acute reduction in renal mass. The rate of [(14)C]choline incorporation into phospholipid in renal cortical slices was increased by 37% at 5 min of compensatory growth in mice. The rate increased to the maximal value of 68% by 20 min and remained there for 3 h. The rate then remained increased at 28-34% above nor...
متن کاملCompensatory and obligatory renal growth in rats.
SILBER, SHERMAN, AND RICHARD L. MALVIN. Compensatory and obligatory renal growth in rats. Am. J. Physiol. 226(l) : 114-l 17. 1974.-Renal size and function were studied in three groups of rats in an attempt to gain information relating to the control of renal size. One group consisted of normal rats into which a third kidney was transplanted; a second group consisted of unilaterally nephrectomiz...
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 کاملMetabolic Response to Renal Compensatory Growth
Forty-eight hours after unilateral nephrectomy in young male Sprague-Dawley rats the concentrations of free methionine, alanine and tyrosine in renal cortical tissue were increased by 15-65 percent while the corresponding plasma concentrations decreased by 23-35 percent. The renal cortical concentrations of valine and leucine increased by 41 percent and 26 percent while plasma concentrations re...
