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

Previous researches showed T-cadherin (CDH13) expression was downregulated in colon cancer tissues and was associated with increase of invasive and metastatic potential. This research was to observe the mechanisms responsible for inactivation of T-cadherin gene in colon carcinoma; we investigated the methylation status around the 5' promoter region of T-cadherin gene of Hct116 colon cancer cell line by methylation-specific polymerase chain reaction (MSP), also detected the expression change of T-cadherin mRNA and protein in Hct116 cell line after 5-Aza-CdR treatment by reverse transcriptase polymerase chain reaction and Western blotting, and compared the T-cadherin methylation status with T-cadherin mRNA and protein expression. We found that hypermethylation of T-cadherin was involved in Hct116 cell line, while T-cadherin mRNA and protein expression was almost lost or downregulated in Hct116 cell line. Therefore, methylation of the T-cadherin promoter region was correlated with the loss or downregulation of T-cadherin mRNA and protein expression in Hct116 colon cancer cell line. Treatment of T-cadherin-negative carcinoma cells with the demethylating agent, 5-aza-2'-deoxycytidine, induced re-expression of this gene. Our findings demonstrate that 5' CpG island methylation is common in colon carcinoma and may play an important role in the inaction of T-cadherin. Our results also suggest that demethylation of the T-cadherin gene may be a potential therapeutic strategy for colon carcinoma.
