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

The potential anti-senescence gene Klotho (KL) has been recently found to participate in the progression of several different human cancers including breast, lung, and cervical cancer. In this current study, we identified KL as a candidate tumor suppressor gene silenced through promoter hypermethylation in colorectal cancer (CRC). KL gene expression is found to be absent or reduced in colon cancer cell lines (5/6, 83.3%), which can be reversed by treatment with demethylation agent 5-aza-2'-deoxycytidine (Aza), but not HDAC inhibitor trichostatin A. In addition, KL expression is markedly downregulated in colorectal carcinoma tissues when compared to the adjacent nontumor tissues (n=25, p<0.001). The methylation of the KL gene promoter was frequently detected in primary tumor tissues (34/40, 85%) when compared with adjacent nontumor colon tissues. Furthermore, ectopic expression of KL led to the cell proliferation inhibition of colon cancer cell lines via the induction of cell apoptosis and S-phase cell cycle arrest. Taken together, our results suggest that KL is inactivated through promoter hypermethylation and potentially functions as a tumor suppressor gene in CRC.
