Involvement of GnRH, PACAP and PRP in the reproduction of blue gourami females (Trichogaster trichopterus).
Article in Journal of molecular neuroscience : MN, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In vertebrates, gonadotropin-releasing hormone (GnRH) and pituitary adenylate cyclase-activating polypeptide (PACAP) are key hormones regulating growth and reproduction in the brain-pituitary axis. The regulating hormonal interactions are of great interest, therefore, the aim of this study is to provide novel insights into the involvement of brain GnRH and PACAP in oogensis and spermatogenesis in a fish model, the blue gourami (Trichogaster trichopterus). cDNA cloning of two GnRH forms combined with phylogenetic analysis revealed that three paralogous GnRH forms exist in blue gourami and evolve as a result of genome duplication. GnRH1 mRNA levels are related to final oocyte maturation (FOM), and this peptide stimulated β follicle-stimulating hormone (βFSH) and growth hormone (GH) gene expression; GnRH2 stimulated β gonadotropins (GtH) gene expression and GnRH analog combined with PACAP-38 synergistically upregulate GH and βFSH gene expression. The data presented, together with previous studies in our lab, enable suggesting mechanisms explaining the physiological relevance of these peptides in the regulation of gametogenesis and steroidogenesis in blue gourami females. These findings support the biological importance of the GnRH and PACAP hormones family, enabling them to stimulate differential biological functions in the regulation of growth and reproduction.
