合成的心房肽、大鼠心房钠尿肽、atriopeptin I 和 atriopeptin II 以时间和浓度依赖性方式刺激小鼠 Leydig 细胞产生睾酮。肽对类固醇生成的最大刺激是基础水平的 6-10 倍,而饱和浓度 hCG 的刺激是基础水平的 20-24 倍。在磷酸二酯酶抑制剂 3-异丁基-1-甲基黄嘌呤存在下,最有效的肽心肽素 II 对类固醇生成的刺激显着增强,表明环核苷酸的参与。然而,cAMP 的基础水平和 hCG 刺激水平都没有被该肽改变,尽管在 atriopeptin II 存在的情况下,响应次最大浓度 hCG 的睾酮产生增加。所涉及的第二信使的性质和心房肽的作用机制可能通过正在进行的进一步研究来阐明。
The synthetic atrial peptides, rat atrial natriuretic peptide, atriopeptin I and atriopeptin II, stimulated testosterone production by mouse Leydig cells in a time‐ and concentration‐dependent manner. The maximum stimulation of the steroidogenesis in response to the peptides was 6–10‐fold over the basal level, as compared with 20–24‐fold stimulation obtained with saturating concentrations of hCG. The stimulation of steroidogenesis by the most potent peptide, atriopeptin II, was markedly enhanced in the presence of the phosphodiesterase inhibitor, 3‐isobutyl‐1‐methylxanthine, suggesting an involvement of cyclic nucleotides. However, neither basal nor hCG‐stimulated levels of cAMP were altered by the peptide, though testosterone production in response to submaximal concentrations of hCG was increased in the presence of atriopeptin II. The nature of the second messenger involved and the mechanism of action of the atrial peptides may by elucidated by further research in progress.
