Selection of reliable reference genes for analysis of gene expression in the rat placenta.

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 selection of suitable reference genes (RGs), especially the identification of the proper combination of RGs is the key to obtain reliable results of gene expression for quantitative real-time polymerase chain reaction (qRT-PCR). To date, there is no relevant study dealing with the stability of RGs in rat placenta. In this study, the geNorm, NormFinder, and BestKeeper software were used to analyze the expression stability of the candidate RGs in placenta under physiological and prenatal caffeine exposure (PCE) conditions. The expression of Tbp, Gapdh and Ywhaz in female and Polr2a, Gapdh and Ywhaz in male placenta were highly stable under physiological conditions, and there was no obvious gender difference. We further found that two RGs were sufficient for reliable normalization in female and male placenta and the combination of Ywhaz and Gapdh was the most suitable compound RGs under physiological conditions. Under PCE conditions, Ywhaz, Gapdh and Polr2a were the most stable genes in both female and male placenta. Among them, Ywhaz and Gapdh were chosen as the best paring. Finally, selected RGs were employed for normalization of the expression of a clear target gene and the results of standardization supported our choice. In conclusion, our study confirmed that Ywhaz/Gapdh combination was the most suitable RGs in rat placenta under physiological and PCE pathological conditions and provided a theoretical and experimental basis for physiological and pathological research of the rat placenta.
