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

The growth arrest DNA damage-inducible gene (Gadd45) family, which is composed of Gadd45A, Gadd45B, and Gadd45G, is involved in DNA damage response and cell growth arrest. The present study was to detect the role of Gadd45 gene family in esophageal cancer and the relationship of Gadd45G methylation to a series of pathological parameters in a large esophageal squamous cell carcinoma (ESCC) sample, in order to elucidate more information on the role of Gadd45 gene family with regard to the pathogenesis of ESCC. Frequent silencing of Gadd45G but not Gadd45A and Gadd45B were found in esophageal cancer cell lines and the silencing of Gadd45G may be reversed by 5-Aza-dC or TSA treatment in Eca109 cell line. The aberrant proximal promoter methylation of Gadd45G induces silencing of Gadd45G expression in Eca109 cell line. Gadd45A mRNA and protein expression in ESCC tumor tissues was significantly different compared to corresponding normal tissues. Decreased mRNA and protein expression of Gadd45G was observed in ESCC tumor tissues and was associated with Gadd45G proximal promoter methylation. Gadd45A or Gadd45B expression was not correlated with ESCC patients survival, while Gadd45G methylation status and protein expression were independently associated with ESCC patients' survival. These data indicated that Gadd45G may be a functional tumor suppressor and its inactivation through proximal promoter methylation may play an important role in ESCC carcinogenesis and reactivation of Gadd45G gene may has therapeutic potential and may be used as a prognostic marker for ESCC patients.
