Aberrant TIG1 methylation associated with its decreased expression and clinicopathological significance in hepatocellular carcinoma.
Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Recently, it has been reported that tazarotene-induced gene 1 (TIG1) methylation was frequently detected in a variety of human cancers. However, the relationship between the TIG1 methylation and the characteristics of hepatocellular carcinoma (HCC) remains unknown. The aim of present study was to observe the promoter methylation of TIG1 in HCC tissues and assess its prognostic significance for HCC. Real-time quantitative polymerase chain reaction and methylation-specific polymerase chain reaction were used, respectively, to examine the mRNA expression and methylation status of TIG1 in 91 pairs of HCC and adjacent noncancerous tissues. The mRNA expression level of TIG1 was significantly lower in HCC tissues than in adjacent noncancerous tissues. The rate of TIG1 promoter methylation was significantly higher in HCC tissues than in adjacent noncancerous tissues (P < 0.001). A strong correlation between downregulation and promoter methylation was found in these tumors (P < 0.001). More importantly, TIG1 methylation status was related to tumor size (P = 0.015), histological differentiation (P = 0.004), and tumor stage (P < 0.001). Kaplan-Meier survival analysis showed that TIG1 promoter hypermethylation was associated with a worse outcome in patients with HCC. Further, Cox multivariate analysis indicated that TIG1 methylation status was an independent prognostic factor for the overall survival rate of HCC patients. In conclusion, our data suggested that epigenetic silencing of TIG1 gene expression by promoter hypermethylation may play an important role in HCC.
