The effect of hormonal imprinting on 3H-steroid incorporation of Tetrahymena pyriformis.
Steroid hormones are incorporated by Tetrahymena, and appear intracellularly in both cytoplasmic and intranuclear localizations. At primary interaction with the steroid, incorporation was the greatest at 10 min, whereas at the second interaction it tended to increase with time. The Tetrahymena cells preexposed to a steroid incorporated a greater amount of it at the second exposure, owing presumably to the induction of steroid receptors at the first interaction.
