Monitor of the myostatin autocrine action during differentiation of embryonic chicken myoblasts into myotubes: effect of IGF-I.

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
Myogenesis is regulated through the proliferation and differentiation of myoblasts expressing myostatin which functions as a negative regulator by generating Smad signals. Here, we monitored the autocrine action of myostatin in quiescent chicken myoblasts transfected with the Smad-mediated promoter reporter vector to evaluate the modulation of several growth factors. During differentiation of myoblasts into myotubes, stretched and spherical types of myoblasts were observed at 12 h after induction, at which the promoter activity began to increase. Maximal promoter activity was observed at approximately 30 h. Multinucleated myotubes were markedly formed at 72 h, but the activity was very low. IGF-I, known as a positive regulator of myogenesis, increased the promoter activity, but the increase was rather small at its high concentration (100 ng/ml). IGF-I significantly increased the level of myostatin transcript in myoblasts and newly formed myotubes at 24 h, but not at 36 h. However, the cell fusion of myoblasts was not accelerated in the presence of IGF-I. Consequently, this study indicates that the autocrine action of myostatin is partially enhanced by IGF-I through increasing its expression.
