Circadian [3H] leucine incorporation into protein of the rat brain: sex differences.
The incorporation of 3H from [3H]leucine into protein in various regions of the brain and in the anterior pituitary was measured at 6-h intervals throughout a 24-h period in groups of male and female rats. No rhythm was observed in the male, while there were significant circadian rhythms in certain areas of the female brain, with peaks at 15.00 h. Statistically significant rhythms of the acid-soluble tritium and of the protein concentrations in the individual tissues were also observed, but were unrelated to the rhythms of incorporation of the label into protein.
