title: Thyroxine interaction with actinomycin D and possible biological implications.
abstract: Actinomycin D and thyroxine interact in solution (pH 8 to 10), as revealed by changes in the absorbance of actinomycin D. Thyroxine can prevent the growth-inhibitory effect of actinomycin D on Bacillus subtilis if it is present in a molar ratio of 3000 (thyroxine to actinomycin D).
