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

PCDH10 is a key tumor suppressive gene for nasopharyngeal, esophageal, and other carcinomas with frequent methylation. In this study, we investigated the potential epigenetic modification of the PCDH10 gene by hepatitis B virus × protein (HBx), a pivotal factor in the progression of HBV replication and potential carcinogenesis. PCDH10 expression was found to be down-regulated in 9/13 (69.2 %) of hepatocellular carcinoma (HCC) cell lines. Decreased PCDH10 expression was correlated with the methylation status of the PCDH10 promoter. Treatment with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (Aza) was sufficient to restore PCDH10 mRNA expression by suppressing PCDH10 promoter methylation in HepG2 cells. Treatment with Trichostatin A alone had no significant effect on PCDH10 expression but enhanced the effect of Aza. PCDH10 methylation was further detected in 76 % (38 of 50) of HCC tissues compared with 40 % (20 of 50) of paired adjacent tissues, with no methylation detected in normal human liver tissues. There were significant correlations between methylation status of PCDH10 and tumor size, serum AFP levels, metastasis or TNM staging (P < 0.05). Moreover, PCDH10 promoter methylation status was not associated with HBV infection in our panel of 50 primary HCC tumors, and transfection with HBX could not alter the status of PCDH10 promoter methylation. Collectively, these observations suggested that the expression of PCDH10 was silenced in HCC via de novo DNA methylation independent of HBV infection or HBX expression, and PCDH10 might form a potentially useful therapeutic target for HCC.
