Augmentation of the cAMP level has no positive effect on hormonal imprinting in Tetrahymena. Artificial elevation of the cAMP level may inhibit the development of imprinting or may result in abnormal imprinting. The role of Ca2+ is of great importance in mediation of the imprinting mechanism. Generally, this role is not influenced by an elevated cAMP level but, exceptionally, the latter may effect the mechanism of imprinting.
环磷酸腺苷(cAMP)水平的升高对四膜虫中的激素印记没有积极影响。人为提高cAMP水平可能会抑制印记的发展,或者导致异常印记。钙离子(Ca2+)在印记机制的介导中起着至关重要的作用。一般来说,这种作用不受cAMP水平升高的影响,但例外的是,后者可能会影响印记机制。
