1. The respiration rate of ova during their early cleavage stage from two groups of rats reared on diets of NDpCal% 10 or NDpCal% 5 has been measured, using a Cartesian diver.2. Measurements from twenty-six experiments show that the average oxygen uptake of ova from the rats reared on the diet of high protein value was 0.563±0.175 mμl O2/ovum per h and the value for rats reared on the diet of low protein value was 0.440±0.076 mμl O2/ovum per h when measurements were made in a medium containing 0.9% NaCl and rat serum or plasma (2:1). The difference between these results was significant at 0.05 > P > 0.02.3. It is suggested that the lower respiration rate of ova from rats maintained on the diet of low protein value may be due partly to the effect of dietary protein deficiency on conditions within the Fallopian tube and partly to the eRect on the maturation of the ovum itself.

Protein intake has been recognized as a modulator of renal function for over half a century. This review analyzes the renal response induced by changes in habitual protein intake and with acute amino acid infusion or a meat meal in humans and animals. The pattern and magnitude of changes in GFR and creatinine clearance are examined along with a discussion of the effect of the variability of these measurements among individuals and populations on the interpretation of clinical studies. Potential mechanisms of protein-induced changes in GFR and creatinine clearance are examined, including changes in the hormonal milieu, glomerular hemodynamics, and other intrarenal processes. Habitual dietary protein consumption varies significantly with respect to age, gender, and lean body mass--factors that are well known to influence GFR. This correlation raises the possibility that (1) variation in dietary protein intake may account, at least in part, for the differences in renal function among individuals; and (2) the level of protein intake should be assessed in defining the normal range of renal function.

Induced Changes

The effect of dietary protein on the initiation of mRNA translation was examined in rats starved for 18 h and then fed isocaloric diets containing either 20% protein (20P) or no added protein (0P). Feeding the 20P diet, but not the 0P diet, stimulated protein synthesis in skeletal muscle and liver by 38 and 41%, respectively. The stimulation was associated with reduced binding of eukaryotic initiation factor (eIF) 4E to the translational repressor 4E-BP1, increased formation of the active eIF4E-eIF4G complex, and increased phosphorylation of 4E-BP1. In contrast, feeding a 0P diet had no effect on any of these parameters. Feeding a 20P diet resulted in partial dephosphorylation of eIF4E in both tissues. In liver, refeeding a 0P diet also resulted in partial eIF4E dephosphorylation, suggesting that the phosphorylation state of eIF4E is not important in the stimulation of protein synthesis under these conditions. Finally, plasma insulin concentrations were the same in rats fed either diet (14.8 ± 4.9 vs. 15.5 ± 4.5 μU/ml for 20P and 0P groups, respectively), suggesting that feeding-induced changes in plasma insulin are not sufficient to stimulate protein synthesis. Instead, a combination of dietary protein and insulin may be required to stimulate translation initiation.

A CCK-deficient mouse mutant generated by gene targeting in embryonic stem cells was analyzed to determine the importance of CCK for growth and function of the exocrine pancreas and for pancreatic adaptation to dietary changes. RIAs confirmed the absence of CCK in mutant mice and demonstrated that tissue concentrations of the related peptide gastrin were normal. CCK-deficient mice are viable and fertile and exhibit normal body weight. Pancreas weight and cellular morphology appeared normal, although pancreatic amylase content was elevated in CCK-deficient mice. We found that a high-protein diet increased pancreatic weight, protein, DNA, and chymotrypsinogen content similarly in CCK-deficient and wild-type mice. This result demonstrates that CCK is not required for protein-induced pancreatic hypertrophy and increased proteolytic enzyme content. This is a novel finding, since CCK has been considered the primary mediator of dietary protein-induced changes in the pancreas. Altered somatostatin concentrations in brain and duodenum of CCK-deficient mice suggest that other regulatory pathways are modified to compensate for the CCK deficiency.
