| Abstract |
SOX1 is epigenetically inactivated in hepatocellular carcinoma. However, the expression and methylation status of SOX1 in non-small cell lung cancer (NSCLC) remains unknown. The aim of the current study was to investigate whether the promoter hypermethylation of SOX1 is involved in human lung carcinogenesis. We first detected the expression of SOX1 protein in a tissue microarray (TMA) of primary NSCLC and adjacent normal lung tissue specimens using immunohistochemical staining with a specific anti-SOX1 antibody. Methylation of the promoter region of SOX1 in lung cancer tissues was determined by bisulfite sequencing PCR (BSP). In the present study, we found that the SOX1 promoter was fully or partially methylated in 40 of 60 (66.7 %) tumor tissues but not in the majority 15 of 60 (25 %) of normal tissues. A statistically significant inverse association was found between SOX1 methylation status and expression of the SOX1 in tumor tissues (P = 0.003). We further demonstrate that restoration of SOX1 inhibited cell migration by regulating actin cytoskeletal remodeling. Our results suggest that SOX1 is epigenetically silenced in the majority of NSCLC and restoration of SOX1 inhibited cell migration by regulating actin cytoskeletal remodeling in NSCLC. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 24 January 2015.
All research outputs
#20,249,662
of 22,778,347 outputs
Outputs from Tumor Biology
#1,834
of 2,622 outputs
Outputs of similar age
#295,426
of 351,530 outputs
Outputs of similar age from Tumor Biology
#106
of 167 outputs
Altmetric has tracked 22,778,347 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% 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 is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
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 351,530 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 167 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
