Involvement and expression of growth hormone/insulin-like growth factor member mRNAs in the ovarian development of turbot (Scophthalmus maximus).

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
Accumulating evidence suggests that the growth hormone (GH)/insulin-like growth factor (IGF) system participates in fish reproduction. To understand the physiological functions of the GH/IGF system, the mRNA expression profiles of all known members of the GH/IGF system, including hepatic and ovarian gh, GH receptor (ghr), IGFs (igf-i, igf-ii), IGF-I receptor (igf-ir) and IGF binding protein (igfbp1, igfbp2), pituitary gh, and hepatic vitellogenin (vtg) were investigated during ovarian development in turbot Scophthalmus maximus. Results showed that ghr, igf-i, igf-ii, igf-ir, and igfbp2 were expressed in the liver and ovary, whereas igfbp1 and gh were undetected. The hepatosomatic index (HSI) and gonadosomatic index (GSI) gradually increased and peaked during the late vitellogenesis (Latvtg) and migratory nucleus (Mig-nucl) stages, respectively. The mRNA expression profiles of ovarian ghr, igf-ii, hepatic igf-ir, vtg, and pituitary gh were similar to the HSI; ovarian igf-i and igf-ir expression was close to the GSI. However, the hepatic mRNA levels of ghr, igf-i, and igf-ii peaked at the early vitellogenesis (Evtg) stage, and then drastically declined during ovarian development. The mRNA expression of hepatic igfbp2 decreased and reached the lowest at the atresia (Atre) stage, whereas that of ovarian igfbp2 increased and peaked at Latvtg stage. Furthermore, significant correlations between pituitary gh, ovarian ghr, igf-i, and igf-ii, and hepatic ghr, igf-i, igf-ir, and igf-ii were observed, respectively. These results suggest that GH/IGF members appear to play distinct roles in the regulation of ovarian development in turbot and will be valuable for fish reproduction and broodstock management of aqua-cultured fish species.
