| Abstract |
Recent studies reveal that long noncoding RNAs (lncRNAs) play critical regulatory roles in cancer biology. Prostate cancer-associated ncRNA transcript 1 (PCAT-1) is one of the lncRNAs involved in cell apoptosis and proliferation of prostate cancer. This study aimed to assess the potential role of PCAT-1 specifically in the pathogenesis of esophageal squamous cell carcinoma (ESCC). Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of PCAT-1 in matched cancerous tissues and adjacent noncancerous tissues from 130 patients with ESCC, 34 patients with non-small cell lung cancer (NSCLC), and 30 patients with gastric carcinoma (GC). The correlation of PCAT-1 with clinicopathological features and prognosis were also analyzed. The expression of PCAT-1 was significantly higher in human ESCC compared with the adjacent noncancerous tissues (70.8 %, p < 0.01), and the high level of PCAT-1 expression was significantly correlated with invasion of the tumor (p = 0.024), advanced clinical stage (p = 0.003), lymph node metastasis (p = 0.032), and poor prognosis. However, PCAT-1 mRNA expression had no significant difference between paired primary cancerous tissues and the adjacent noncancerous tissues in 34 cases of NSCLC (p = 0.293) and 30 cases of GC (p = 0.125). High expression of PCAT-1 was specifically correlated with invasion of cancer tissues, metastasis of lymph node, and advanced tumor stage of ESCC. High expression of PCAT-1 might reflect poor prognosis of ESCC and indicate a potential diagnostic target in ESCC patients. Adjuvant therapy targeting PCAT-1 molecule might be effective in treatment of ESCC. |

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 10 March 2015.
All research outputs
#15,326,126
of 22,794,367 outputs
Outputs from Tumor Biology
#1,050
of 2,622 outputs
Outputs of similar age
#152,885
of 257,854 outputs
Outputs of similar age from Tumor Biology
#51
of 174 outputs
Altmetric has tracked 22,794,367 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% 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 53% 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 257,854 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 174 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 69% of its contemporaries.
