CpG methylation in the Fhit regulatory region: relation to Fhit expression in murine tumors.
Article in Oncogene, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 2 of them syntheses that pooled 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.
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
To determine if: (1) 5' CpG island methylation is related to Fhit inactivation; (2) there are tumor or carcinogen-specific methylation patterns, we examined 35 CpG sites in the promoter, exon and intron 1 of the mouse Fhit gene. In primary tumors of lung, urinary bladder and tongue, induced by different carcinogens, 15-35% of sites were methylated, with specific methylation patterns associated with each cancer type, suggesting cancer- or tissue-specific methylation patterns. The methylation patterns were associated with reduced Fhit expression, as determined by immunohistochemical analyses. Methylation of rat Fhit 5' CpGs in mammary adenocarcinomas, detected by methylation specific PCR amplification, also correlated with reduced gene expression. Thus, there was an overall association between promoter/exon 1 methylation and decreased Fhit expression. In contrast, in cancer-derived cell lines 70-95% of the CpG sites were methylated. This is the first detailed study of the relationship between Fhit 5' CpG island methylation and Fhit expression in murine tumors, our main models for preclinical cancer studies, and provides evidence that loss of Fhit expression and methylation are correlated in these mouse models and these models will be useful to examine the complex relationships among gene expression, methylation patterns and organ specificity.
