| Abstract |
The underlying molecular pathogenesis in gastric cancer remains poorly unknown. The transcription factor myocyte enhancer factor 2D (MEF2D) participates in the initiation and development of many human cancers. However, its potential roles in gastric cancer have surprisingly not been studied. In present study, we first explored MEF2's expression in gastric cancer, finding that only MEF2D rather than MEF2A, 2B, or 2C was elevated in gastric cancer clinical specimens. Furthermore, immunohistochemical analysis on the tissue samples obtained from 260 patients with gastric cancer revealed that MEF2D expression was significantly associated with the clinical stage, vascular invasion, metastasis, and tumor size. Gastric cancer patients with MEF2D expression showed a significantly shorter overall survival time compared with that of patients lacking of MEF2D. Multivariate analysis revealed that MEF2D expression was an independent prognostic factor for overall survival. These results indicated that MEF2D was a prognostic marker for gastric cancer. Notably, MEF2D silencing was able to reduce the proliferation and survival of gastric cancer cells. Further study revealed that MEF2D suppression significantly inactivated the oncogenic Wnt/β-catenin pathway. Downregulation of MEF2D inhibited the tumorigenesis of gastric cancer cells in nude mice. Finally, MEF2D is a direct target of miR-19, which was found to be decreased in gastric cancer clinical specimens. Collectively, we found that miR-19/MEF2D/Wnt/β-catenin regulatory network contributes to the growth of gastric cancer, hinting a new promising target for gastric cancer treatment. |

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 16 January 2016.
All research outputs
#18,436,183
of 22,840,638 outputs
Outputs from Tumor Biology
#1,369
of 2,622 outputs
Outputs of similar age
#285,744
of 395,522 outputs
Outputs of similar age from Tumor Biology
#96
of 264 outputs
Altmetric has tracked 22,840,638 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% 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 30th percentile – i.e., 30% 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 395,522 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 264 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
