| Abstract |
Gastric cancer (GC) is a fatal malignancy with high rate of recurrence and metastasis. Here, we investigated the correlations between the expression of autophagic protein LC3B and 2 epithelial-mesenchymal transition-related proteins (E-cadherin and Vimentin) and the clinicopathological factors and prognosis of patients with GC. The expression of LC3B, E-cadherin, and Vimentin in GC samples (110 cases) and paracarcinoma tissues (40 cases) was analyzed using the Oncomine databases and further detected by immunohistochemistry. The correlations among these markers expression and clinicopathological features in GC were analyzed. The patients were followed for survival analysis. Compared to the nontumor tissues, the expression of LC3B and Vimentin proteins were significantly elevated in GC tissues, but the E-cadherin expression was decreased (all p<0.05). Interestingly, LCB expression was positively correlated with Vimentin (r=0.320, p=0.001) and negatively associated with E-cadherin expression (r= -0.484, p<0.001) in GC. The expression of these markers was closely related to tumor differentiation, T classification, TNM stage, and lymph node metastasis (all p<0.05). Furthermore, survival analyses and screening Kaplan-Meier plotter database revealed that GC patients with high LC3B and Vimentin expression levels had a poorer clinical outcome than those with low expression. Conversely, high E-cadherin expression was linked with favorable overall survival (all p<0.05, log-rank test). Multivariate survival analysis demonstrated that LC3B, E-cadherin, and Vimentin expression were independent prognostic factors of GC patients. LC3B, E-cadherin, and Vimentin may play an important role in the tumorigenesis of GC, and these marker expressions may serve as additional prognostic indicators for overall survival of patients. The interactions of autophagy and epithelial-mesenchymal transition in GC merits further investigation. |

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 25 June 2018.
All research outputs
#17,981,442
of 23,092,602 outputs
Outputs from Cancer Management and Research
#948
of 2,017 outputs
Outputs of similar age
#238,786
of 330,325 outputs
Outputs of similar age from Cancer Management and Research
#40
of 72 outputs
Altmetric has tracked 23,092,602 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,017 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 47th percentile – i.e., 47% 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 330,325 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 22nd percentile – i.e., 22% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 72 others from the same source and published within six weeks on either side of this one. This one is in the 41st percentile – i.e., 41% of its contemporaries scored the same or lower than it.
