THE EFFECT OF ADRENOCORTICOTROPHIN ON THE NUCLEIC ACID METABOLISM OF THE RAT ADRENAL GLAND

Abstract
SUMMARY: Treatment of female rats with adrenocorticotrophin (ACTH) increased the RNA content of the adrenal glands progressively during a period of 3 days, the DNA content increased only after prolonged administration. By contrast, ACTH caused a decrease in the uptake of [32P]orthophosphate into the total RNA of the gland and into most of the RNA fractions of the subcellular components. A method of analysis for RNA and DNA based on the Schmidt-Thannhauser procedure has been evolved which eliminates extraction of nucleic acid by lipid solvents.
