项目摘要
Pigment-dispersing action of tilapia prolactin 177 (tPRL177) and ovine prolactin (oPRL) on erythrophores and xanthophores was found in some fish species. The action was direct on such cells. PRL had no effect on cultured melanophores in any teleost species examined. Therefore, we conclude that the pigment-dispersing effect of PRL on erythrophores and xanthophores and the inefficacy of PRL on melanophores are general properties in teleosts. In fish species possessing many erythrophores and/or xanthophores in their skin throughout the year, the cells responded to PRL all the time. However, in species that reveal the nuptial coloration in the spawning season, erythrophores responded better to PRL in spring and summer as compared with late fall and winter. The seasonal chane in responsiveness of erythrophores suggests the involvement of PRL in the nuptial coloration and an augmentation of red color by pigment dispersion in the spawning season. Next, plasma levels of tPRL177 and tPRL188 in Oreochromis niloticus in freshwater were ditermined : tPRL177 55.7(]SY+-[)13.2 ng/ml, tPRL188 3.2(]SY+-[)1.0 ng/ml. In O.niloticus, the relative effectiveness on erythrophores and xanthophores was as follows : tPRL177>oPRL>tPRL188. Therefore, it is likely that tPRL177 actually affects the skin color of the fish species. The plasma levels of tPRLs in O.niloticus assuming the nuptial coloration will be determined in near future. Although prolactin and androgen were injected into abdorminal cavity of O.niloticus every other day for 2 weeks, the nuptial coloration did not appear. Further experiments will be required. Signal transduction of PRL was examined in erythrophores and xanthophores isolated from some fish species. Cyclic AMP was found to be to the intracellular second messenger.
罗非鱼催乳素177(tPRL 177)和绵羊催乳素(oPRL)对某些鱼类的红细胞和黄细胞有分散色素的作用。行动直接针对这些细胞。催乳素没有影响培养的黑色素细胞在任何硬骨鱼类检查。因此,我们得出结论,PRL对红细胞和黄细胞的色素分散作用和PRL对黑色素细胞的无效性是硬骨鱼类的一般性质。在全年皮肤中具有许多红细胞和/或黄细胞的鱼类中,细胞一直对PRL有反应。然而,在物种,揭示了在产卵季节的婚色,红细胞PRL在春季和夏季的反应比深秋和冬季。红细胞反应性的季节性变化表明PRL参与了婚色,并在产卵季节通过色素分散增加了红色。测定了淡水条件下尼罗罗非鱼血浆中tPRL 177和tPRL 188的含量:tPRL 177 55.7(± SY)13.2 ng/ml,tPRL 188 3.2(± SY)1.0 ng/ml。在尼罗罗非鱼中,对红细胞和黄细胞的相对有效性如下:tPRL 177>oPRL> tPRL 188。因此,很可能tPRL 177实际上会影响鱼类的肤色。在不久的将来,将确定假定婚色的尼罗罗非鱼血浆中tPRL的水平。隔一天腹腔注射催乳素和雄激素,连续2周,未出现婚色。还需要进一步的实验。从一些鱼类分离的红细胞和黄细胞中检测PRL的信号转导。环磷酸腺苷是细胞内第二信使。
