Background: As master regulator of embryonic morphogenesis, homeodomain-containing gene 10 (HOXC10) has been found to promote progression of human cancers and indicates poor survival outcome. However, the role of HOXC10 in lung adenocarcinoma still unclear. Methods: HOXC10 expression was evaluated in 63 primary lung adenocarcinoma tissues from our local hospital, and further systematically confirmed in lung cancer tissues from six GEO datasets (GSE19188, GSE31210, GSE10072, GSE7670, GSE32863, GSE30219), and Kaplan-Meier plotter database. The role of HOXC10 in lung cancer metastasis was further validated by cellular and molecular studies. Results: The expression of HOXC10 was significantly increased in human lung adenocarcinoma samples from Wuhu No.2 People's Hospital, about 4.219 times compared with normal tissues, and significantly correlated with TNM stage, lymph node, and distal metastasis. Upregulation of HOXC10 indicated a poor overall/relapse free survival of lung cancer patients from Wuhu No.2 People's Hospital, GEO datasets, and Kaplan-Meier plotter database, especially in patients with lung adenocarcinoma. Knockdown or ectopic expression assays confirmed that HOXC10 enhanced the phosphorylation of PI3K, regulated the expression of epithelial-to-mesenchymal transition (EMT) markers: MMP2/9, VCAM-1, vimentin and E-cadherin. Cellular study further confirmed that HOXC10 was required for migration, invasion and adhesion of lung cancer cells. Conclusion: These findings suggest that HOXC10 plays a pivotal role in the metastasis of human lung cancer and highlight its usefulness as a potential prognostic marker or therapeutic target in human lung adenocarcinoma.

Attention Score in Context
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 04 August 2017.
All research outputs
#20,441,465
of 22,996,001 outputs
Outputs from Frontiers in Physiology
#9,468
of 13,754 outputs
Outputs of similar age
#277,089
of 317,618 outputs
Outputs of similar age from Frontiers in Physiology
#200
of 274 outputs
Altmetric has tracked 22,996,001 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 13,754 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.6. 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 317,618 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 274 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.
