Steroid hormones activate gonadotrophs in juvenile male African catfish, Clarias gariepinus. Northern blot analysis revealed a single pituitary PRL transcript, the expression of which was significantly reduced by E 2 treatment in adults but significantly increased in juvenile fish. Prolactin PRL is a kDa polypeptidic hormone secreted by the anterior pituitary in all vertebrates [ 12 ]. Skip to main content. The cellular localization of sbPRLR in the gonads was determined by immunohistochemistry using specific polyclonal antibodies raised against an oligopeptide from the extracellular domain of sbPRLR.

A positive immunoreaction is present in spermatogonia SG and the heads of some spermatozoa SZ. A ratio of 1 equivalent concentrations was taken to indicate that equal amounts of competitor and target RNA were present and was used to determine the amount of target RNA in the reaction.

Estrogen receptors in the brain-pituitary complex and the neuroendocrine regulation of gonadotropin release in rainbow trout.

In summary, the present study shows that E 2 affects PRL expression in the pituitary and PRLR gene expression in c-narioo pituitary and gonads, depending on the stage of maturity. Prolactin PRL in fish is considered to be an osmoregulatory hormone, although some studies suggest that it may influence the production of steroid hormones in the gonads. Primers were then prepared for competitor template DNA. The upper band corresponds to the competitor.

The target RNA was quantified by densitometry plotting of the ratio of competitor to target band intensity as a function of the initial amounts of the competitor cRNA added fold dilutions ranging from 0. Questions or concerns relating to the accessibility of the C-naroo online public file system should be directed to the FCC atTTYor fccinfo fcc.


Short-term in vivo regulation of Prolactin receptors in the liver, testes, kidneys, and mammary gland of rats.

The gonads of this protandrous hermaphrodite are characterized by their bisexuality and consist of a mediodorsal ovarian area and a lateroventral testicular zone, separated by connective tissue [ 20 ]. The length of the control and E 2 fish were, respectively, Gran, Hinshaw take over Wildcats’ offense.

Cloning, characterization, and tissue distribution of prolactin receptor in the Seabream Sparus aurata. In mammals, estrogens have a positive effect on PRL secretion. Please enable scripts and reload this page.

The mature gonads were composed principally of testicular tissue, with abundant spermatozoa in the sperm duct Fig. Representative Canario previously served six years on the Portsmouth Town Council, from toand held the position of Council President for two years. The pattern of PRLR expression in seabream is more like that in other vertebrate groups, in which more than one PRLR transcript is present in the gonads e.

However, the differing hormonal status of the mature adult and immature juvenile seabream e. The antiserum against the extracellular domain of sbPRLR has ,essanger been characterized for immunohistochemistry [ 18 ]. Oxford University Press is a department of the University of Oxford.

Representative Dennis M. Canario

As a negative control, sterile water substituted for cDNA, and as positive controls, cDNA synthesized from competitor or intestine sample alone was used. Turn off more accessible mode. The effects of oestradiol on the prolactin and growth hormone content of the pituitary of the tilapia, Oreochromis mossambicuswith observations on the incidence of black males.

Do gonadotrophin-releasing hormone neurons express estrogen receptors in the rainbow trout? In adult gonads, four sbPRLR transcripts of 1. A double immunohistochemical study. In fact, one of the characteristic features of juvenile vertebrates is the quiescent state of activity of the brain-pituitary-gonad axis as a functional unit [ 4243 ].


Immunoreactivity in testis was most intense in the spermatogonia, particularly in the region surrounding the nucleus, although the heads of spermatozoa also stained less intensely. Effect de la prolactine ovine sur la testosterone plasmatique et le tractus genital male chez Gobius niger L.

The functional significance of this is unclear. View large Download slide.

Treatment with E 2 resulted in a significant increase in pituitary PRL mRNA in juvenile gilthead seabream, and this agrees with a previously observed, dose-dependent increase in pituitary synthesis of two forms of PRL in E 2 -treated tilapia in vivo and in vitro [ 2425 ].

A range of factors may explain this difference, although it is not possible from the present results to determine the underlying cause s. A strong signal is observed in some oocytes in the perinuclear region Po.

For immunohistochemistry, only gonads from control animals were analyzed. Note that the competitor was loaded in decreasing concentrations from left to right on the gel. A single domain of the estrogen receptor confers deoxyribonucleic acid binding and transcriptional activation of the rat prolactin gene. Click Here to access the online Public Inspection File. Day plans to propose changes to the county’s current dog ordinance that would require kennels to be better maintained, stricter licenses for kennels and inspections by animal control and law enforcement to keep kennels up to standard, particularly for breeds of dogs known to be large and aggressive.
