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 (HNF4-alpha) regulates expression of a number of genes in several metabolic organs. The HNF4-alpha gene has two promoters and encodes at least nine isoforms through differential splicing. In mouse liver, transcription initiates at promoter 2 (P2) during fetal life, but switches to P1 at birth. Developmental and tissue-specific expression of HNF4-alpha in other organs is largely unknown. Here, we examined expression of P1- and P2-derived transcripts in a number of mouse and rat tissues. Both P1 and P2 were active in mouse fetal liver, but P2-derived isoforms were detected 50% more abundantly than P1 transcripts. Conversely, the adult mouse liver expressed significantly higher levels of P1- than P2-derived mRNA. In contrast, in the rat, P1 was used more predominantly in both fetal and adult liver. Exposure of fetal rats to the synthetic glucocorticoid dexamethasone caused suppression of P2 while enhancing hepatic expression of transcripts from P1. This was associated with increased expression of erythropoietin and phosphoenolpyruvate carboxykinase, which are key HNF4-alpha targets in the liver. Unlike liver, the kidney and stomach used promoters more selectively, so that only P1-derived isoforms were detected in fetal and adult kidneys in mice or rats, whereas the stomach in both species expressed P2-derived transcripts exclusively. No significant HNF4-alpha mRNA was detected in the spleen. These data reveal striking developmental and tissue-specific variation in expression of HNF4-alpha, and indicate that this can be influenced by environmental factors (such as exposure to glucocorticoid excess), with potential pathophysiological consequences.
