Persian sturgeon insulin-like growth factor I: molecular cloning and expression during various nutritional conditions.

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
The effects of different periods of starvation (1, 2, 3, and 4 weeks) and subsequent re-feeding (over a 4 week) on the compensatory growth performance and insulin-like growth factor I (IGF-I) mRNA expression in liver and white muscle were investigated in juvenile Persian sturgeon (Acipenser persicus). First, a fragment of 617 nucleotides coding for IGF-I was cloned from liver, which included an open reading frame of 486 nucleotides, encoding a 162 amino acid preproIGF-I. This is composed of a 45 aa for signal peptide, a 117 aa for the mature peptide comprising the B, C, A, and D domains, and a 47 aa for E domain. The mature Persian sturgeon IGF-I exhibits high sequence identities with other sturgeon species and teleost, ranging between 68 and 95 %. The pattern of IGF-I mRNA expression in the liver and white muscle was measured in response to different periods of starvation and subsequent re-feeding. Nutritional status influenced IGF-I mRNA expression pattern in both liver and muscle. IGF-I mRNA expression in the liver increased during starvation, before decreasing after re-feeding. Furthermore, white muscle IGF-I mRNA expression showed better responses to nutritional status and decreased following starvation and increased by re-feeding. However, changes in the expression of IGF-I mRNA were not significantly different between any of the treatments in both tissues. These data suggest that muscle and liver IGF-I mRNA expression do not have a regulatory role for somatic growth induced by compensatory growth in Persain sturgeon.
