“…We also showed that reserve organs (liver and fat bodies) vary in size and weight (Exbrayat 1988a) during the sexual cycle. The presence of abundant mRNAs coding for PRL-R was also observed in the liver of the pregnant female (Exbrayat et al 1997).…”

“…Animals were anesthetized by immersion in water containing an overdose of MS 222 (3 g/l) and preserved in Bouin's fluid (water-saturated solution of picric acid: 300 ml; formalin: 100 ml; acetic acid: 20 ml; Exbrayat 2001). We have already shown that this material can be studied by means of in situ hybridization (Exbrayat and Morel 1995;Exbrayat et al 1997). Visualization for the long form of PRL-R was carried out on males and females captured during the sexual cycle.…”

“…In order to act, it is bound to the surface of the target cell by means of a PRL-R. Using an in situ hybridization technique, mRNA coding for PRL-R has been visualized in several types of tissues in mammals (Clarke et al 1993;Ouhtit et al 1993aOuhtit et al , 1993bOuhtit et al , 1994 and amphibians (Exbrayat et al 1997).…”

The expression of the long form of prolactin receptor (PRL-R) mRNAs was studied in reproductive organs from both male and female Typhlonectes compressicauda, an amphibian, by quantitative in situ hybridization. These PRL-R mRNAs were expressed in all the organs studied. In ovarian tissue, mRNAs coding for the long form of PRL-R were strongly expressed in ovaries with compact and vascularized corpora lutea, i.e., during the middle and the end of pregnancy. During the other periods of cycle, sexual rest, vitellogenesis and beginning of pregnancy, expression of these mRNAs was lower than in other periods. In the testis, mRNAs coding for the long form of PRL-R were expressed in germ cells as well as in Leydig and Sertoli cells. In müllerian glands, important variations of expression in these mRNAs have been observed with a large increase during the breeding period and a decrease during sexual rest. Variations of gene expression of the long form of PRL-R for all tissues studied are correlated to synthesis of PRL in the pituitary in both male and female Typhlonectes compressicauda.

“…Although the distribution of PRL-R in those species has been investigated extensively (e.g. Sandra et al, 1995;Zhou et al, 1996;Exbrayat et al, 1997;Ohkubo et al, 1998), little information is available so far on the distribution of PRL (for sea bream, Santos et al, 1999; for rainbow trout, Yang et al, 1999).…”
