研究了合成鲑鱼黑色素浓缩激素(MCH)对蓝雀鲷(硬骨鱼)Chrysipteracyea 黑色素细胞的体外生物学作用。这种环状十七肽以大约 10−10M 的阈值浓度刺激黑素细胞内黑素体(黑色素颗粒)聚集(向心迁移)。这种假定的激素的作用不被α-或β-肾上腺素受体拮抗剂阻断。结论是,MCH 的影响是直接的,不是通过神经末梢释放的肾上腺素能神经递质的作用间接介导的。这一观点的进一步证据来自观察,与神经递质释放的情况不同,响应 MCH 的黑素体聚集在没有钙的情况下进行。讨论了 MCH 在控制硬骨鱼颜色变化方面的可能作用。
The in vitro biological actions of synthetic chum salmon melanin concentrating hormone (MCH) on melanophores of the blue damselfish (a teleost),Chrysiptera cyanea, were studied. This cyclic heptadecapeptide stimulated melanosome (melanin granule) aggregation (centripetal migration) within melanophores at a threshold concentration of about 10−10M. The action of this putative hormone was not blocked by α‐ or β‐adrenoceptor antagonists. It was concluded that the effects of MCH were direct and were not mediated indirectly through the actions of adrenergic neurotransmitters released from nerve terminals. Further evidence for this view comes from the observation that, unlike the case of neurotransmitter release, melanosome aggregation in response to MCH proceeded in the absence of calcium. The possible role of MCH in the control of color change of teleost fishes is discussed.
