Differences in Akt signaling and metabolism gene expression in the right heart, intraventricular septum and left heart of rodents.

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 right heart is functionally and structurally different from the left heart; however, potential differences in Akt signaling and the expression of metabolic genes between the right heart and left heart in different rodents are still unknown. Using Western blotting and real time quantification polymerase chain reaction, we measured the levels of total Akt, phosphorylated Akt and its downstream targets as well as metabolism genes including glucose transporter 1, glucose transporter 4 (GLUT4), peroxisome proliferator-activated receptor α, peroxisome proliferator-activated receptor γ, peroxisome proliferator-activated receptor δ, peroxisome proliferator-activated receptor gamma coactivator 1α (PGC-1α), and pyruvate dehydrogenase lipoamide kinase isozyme 4. We found that phosphorylated Akt and proline-rich Akt substrate 40 levels were significantly increased in the RV compared with the LV in rats but only had an increased trend in mice. Correspondingly, GLUT4 was significantly increased in the RV compared with the LV both in mice and rats. PGC-1α was significantly increased in the RV compared with the LV in mice but only had an increased trend in rats. Moreover, Akt signaling activity and metabolism genes' expression in the IVS were similar to the RV in mice but to the LV in rats. There were some differences in the activity of Akt signaling and in the levels of metabolism genes among the right ventricle, interventricular septum and left ventricle. Also, the diversity of activity of Akt and metabolism genes between the right ventricle and left ventricle are different between rats and mice. In conclusion, the activity of Akt signaling and the levels of metabolism genes are different among the right ventricle, interventricular septum and left ventricle providing some potential clues for exploring the roles of Akt signaling and cardiac metabolisms in different parts of the heart. Additionally, the differences in Akt activity and metabolism genes' levels between the right and left ventricles are different between mice and rats, to which we should pay attention when using different animal model in heart study.
