单细胞动物和多细胞动物的激素印迹

激素印迹是单细胞动物和多细胞动物的一种生理现象，也是选择参与信号识别过程分子的工具。激素印迹后，受体记忆将遗传给子孙后代，因此其对进化的作用可能是很大的。同时，激素印迹还有利于物种的维持。另外，激素印迹过程还是具有终身效应的临时开放系统的一部分。没有印迹，就没有完全的受体成熟，而不成熟的受体是不能和适量的激素结合的。在围 期诸如治疗药物和环境污染剂等人工合成的物质分子易致错误或病理印迹。许多研究表明错误印迹对生物体具有重要的影响。当然，单细胞动物的激素印迹过程与多细胞动物并不完全一样。

Hormonal Imprinting of Unicellular Animals and Multicellular Animals

Hormonal imprinting is a physiological phenomenon and a tool for selecting the molecules that participate in signal recognition processes at both the unicellular and multicellular level. As receptor memory is inherited through many cell generations, the process may have evolutionary significance. In the mean time, it benefits the maintenance of species. In addition, it is also part of the temporarily open system with lifelong consequences. Without imprinting, there is no complete receptor maturation and the immature receptors are not able to bind hormones in suitable quantities. The presence of artificial molecules in the perinatal critical period (e.g. as a result of medical treatment or environmental pollution) can cause faulty (pathological) imprinting. Many experiments have demonstrated the increasing importance of faulty imprinting. Surely, there is some difference between the hormonal imprinting processes of unicellular and multicellular animals.
