1 · What the graph read from it

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.

2 · The registry

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

Hepatocyte nuclear factor 4 alpha (HNF4α) is a key transcription factor for liver development. Although HNF4α is necessary for hepatoblast differentiation, the function of HNF4α before the hepatoblast differentiation, such as in definitive endoderm differentiation, is not well known. In addition, it is known that there are nine HNF4α isoforms, but the expression and function of each HNF4α isoform during the definitive endoderm differentiation is also not clear. In this study, we examined the expression pattern of HNF4α and its functions in the definitive endoderm differentiation from human induced pluripotent stem (iPS) cells. We found that the HNF4α-1D isoform expression levels were significantly increased during the definitive endoderm differentiation, while the HNF4α-1A isoform expression levels did not change. Therefore, we further examined the function of the HNF4α-1D isoform in definitive endoderm differentiation. HNF4α-1D overexpression or knockdown was found to promote or prevent the definitive endoderm differentiation, respectively. Interestingly, Lefty1 was directly regulated by HNF4α-1D, and Lefty1 knockdown also prevented the definitive endoderm differentiation. These results suggest that HNF4α-1D promotes definitive endoderm differentiation through the regulation of Lefty1. To our knowledge, this is the first report to clarify the expression pattern and function of HNF4α during the definitive endoderm differentiation.
