| Abstract |
Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies in humans, and its prognosis is generally poor even after surgery. The zinc finger of the cerebellum (ZIC1) gene is a novel tumor suppressor gene that plays a crucial role in vertebrate development. Altered expression of ZIC1 is observed in various types of human cancers. The aims of the present study were to investigate the methylation status of ZIC1 in HCC and evaluate its clinical implication. The methylation status of ZIC1 was analyzed in 132 pairs of HCC and corresponding noncancerous tissues by methylation-specific polymerase chain reaction (PCR) (MSP). The expression of ZIC1 messenger RNA (mRNA) in HCC tissues was examined by real-time PCR. Methylation frequency of ZIC1 in HCC was significantly higher than that in the corresponding noncancerous tissues (P < 0.001), and it was correlated with tumor size (P = 0.022), histological differentiation (P = 0.033), and tumor stage (P = 0.009). The downregulation of the ZIC1 mRNA expression in HCC was correlated with the ZIC1 methylation (P < 0.001). The patients with methylated ZIC1 had a poorer overall survival than those without methylated ZIC1 (P < 0.001). Taken together, our results suggested that the hypermethylation may lead to promoter silencing of ZIC1 mRNA and associated with poor survival in HCC. Overall, aberrant methylation is an important mechanism for ZIC1 inactivation in HCC, and ZIC1 methylation may be a promising biomarker for the diagnosis and prognosis of HCC. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 January 2015.
All research outputs
#14,794,387
of 22,778,347 outputs
Outputs from Tumor Biology
#969
of 2,622 outputs
Outputs of similar age
#128,110
of 227,108 outputs
Outputs of similar age from Tumor Biology
#38
of 87 outputs
Altmetric has tracked 22,778,347 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,622 research outputs from this source. They receive a mean Attention Score of 2.2. This one has gotten more attention than average, scoring higher than 60% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 227,108 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 87 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 55% of its contemporaries.
