Promoter and histone methylation and p16(INK4A) gene expression in colon cancer.
Article in Experimental and therapeutic medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The inactivation of the cyclin-dependent kinase inhibitor p16(INK4A) gene by hypermethylation is observed in numerous types of cancer. New findings indicate that DNA and histone methylation act in concert in gene silencing. In this study, we investigated the methylation status of the p16(INK4A) gene promoter and the histone 3 lysine 9 residue in the tumors and matched normal tissue samples from patients with colorectal cancer and analyzed their association with gene expression. The methylation and expression of the p16(INK4A) gene were analyzed by real-time PCR, and histone methylation was analyzed by chromatin immunoprecipitation followed by real-time PCR. p16(INK4A) expression was significantly higher in the tumors compared to normal tissue. Mono-, di- and trimethylation levels of the H3K9 residue were similar in the tumor and normal tissue samples. We did not observe any significant correlation between p16(INK4A) methylation or expression and clinical parameters. Our results suggest that epigenetic modifications of the p16(INK4A) gene and histone lysine methylation do not play a major role in colon carcinogenesis.
