The promoter methylation of the Syk gene in nasopharyngeal carcinoma cell lines.

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 aim of this study was to investigate the mRNA and protein expression levels of the Syk gene as well as its promoter methylation in nasopharyngeal carcinoma (NPC) cell lines. The CNE-1 (highly differentiated), CNE-2 (poorly differentiated) and NP69 (non-cancerous human immortalized nasopharyngeal epithelial cells) cell lines were used in the present study. The MS-PCR, Q-RT-PCR and western blotting methods were used to examine the Syk gene promoter methylation levels and mRNA and protein expression in the three cell lines. The promoter methylation levels in CNE-1, CNE-2 and NP69 cells were 36%, 62% and 0, respectively. The mRNA levels in CNE-1 and CNE-2 cells were 42±3.5 and 28±2% of that in NP69, respectively; the protein levels in CNE-1 and CNE-2 cells were 36±4.5 and 16±2.5 of that in NP69, respectively; the statistical differences between groups were significant. The lower differentiation levels of the NPC cell lines correlate with lower levels of mRNA and protein expression of the Syk gene, as well as higher promoter methylation levels.
