Abstract
Hormonal imprinting takes place at the primary interaction between target cell and hormone, and alters cellular response to the hormone for lifetime (at the unicellular level in many subsequent generations). Imprinting induced in Tetrahymena cells by diiodotyrosine at the optimum temperature of 25 degrees C took effect on re-exposure to the hormone at 25 degrees C and 15 degrees C, but failed to take effect if the cells were first exposed to the hormone at 15 degrees C or 32 degrees C.
摘要
激素印记发生在靶细胞与激素的初次相互作用时，并会改变细胞对该激素的终生反应（在许多后续世代的单细胞水平上）。在25摄氏度的最佳温度下，二碘酪氨酸在四膜虫细胞中诱导产生的印记，在25摄氏度和15摄氏度再次接触该激素时会起作用，但如果细胞首先在15摄氏度或32摄氏度接触该激素，则印记不起作用。
