Epigenetic Modification of Cloned Embryos Improves Nanog Reprogramming in Pigs.
Article in Cellular reprogramming, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
Incomplete reprogramming of pluripotent genes in cloned embryos is associated with low cloning efficiency. Epigenetic modification agents have been shown to enhance the developmental competence of cloned embryos; however, the effect of the epigenetic modification agents on pluripotent gene reprogramming remains unclear. Here, we investigated Nanog reprogramming and the expression patterns of pluripotent transcription factors during early embryo development in pigs. We found that compared with fertilized embryos, cloned embryos displayed higher methylation in the promoter and 5'-untranslated region and lower methylation in the first exon of Nanog. When 5-aza-2'-deoxycytidine (5-aza-dC) or trichostatin A (TSA) enhanced the development of porcine cloned embryos, Nanog methylation reprogramming was also improved, similar to that detected in fertilized counterparts. Furthermore, our results showed that the epigenetic modification agents improved the expression levels of Oct4 and Sox2 and effectively promoted Nanog transcription in cloned embryos. In conclusion, our results demonstrated that the epigenetic modification agent 5-aza-dC or TSA improved Nanog methylation reprogramming and the expression patterns of pluripotent transcription factors, thereby resulting in the enhanced expression of Nanog and high development of porcine cloned embryos. This work has important implications in the improvement of cloning efficiency.
