Promoter methylation blocks FES protein-tyrosine kinase gene expression in colorectal cancer.
Article in Genes, chromosomes & cancer, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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 FES locus encodes a unique nonreceptor protein-tyrosine kinase (FES) traditionally viewed as a proto-oncogene but more recently implicated as a tumor suppressor in colorectal cancer (CRC). Recent studies have demonstrated that while FES is expressed in normal colonic epithelium, expression is lost in tumor tissue and colorectal cancer cell lines, a finding common among tumor suppressors. Here we provide compelling evidence that promoter methylation is an important mechanism responsible for downregulation of FES gene expression in colorectal cancer cells. Treatment with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine resulted in the expression of functional FES transcripts in all CRC cell lines examined, including Caco-2, COLO 320, DLD-1, HCT 116, SNU-1040, SW-480, and HT-29. Bisulfite sequencing of genomic DNA isolated from 5-aza-2'-deoxycytidine-treated HT-29 cells identified methylated CpG dinucleotides immediately upstream from the FES transcription initiation sites. In contrast, this region of the FES promoter was hypomethylated in genomic DNA from normal colonic epithelium. In addition, methylation completely blocked the activity of the FES promoter in reporter gene assays. Promoter methylation is a previously unrecognized mechanism by which FES expression is suppressed in CRC cell lines, and is consistent with a tumor suppressor role for FES in this tumor site despite its tyrosine kinase activity.
