| Abstract |
The endotoxin level in the portal and peripheral veins of hepatocellular carcinoma (HCC) patients is higher and lipopolysaccharide (LPS), has been reported to inhibit tumor growth. However, in this study, we found that LPS-induced Toll-like receptor 4 (TLR4) signaling was involved in tumor invasion and the molecular mechanism was investigated. The HCC cells were used to study the invasion ability of LPS-induced HCC cells and the epithelial-mesenchymal transition (EMT) in vitro. The in vitro experiments demonstrated that LPS could significantly enhance the invasive potential and induce EMT in HCC cells with TLR4 dependent. Further studies showed that LPS could directly activate JNK/MAPK signaling through TLR4 in HCC cells. Interestingly, blocking JNK/MAPK signaling significantly inhibited EMT occurrence. Our results indicate that TLR4/JNK/MAPK signaling is required for LPS-induced EMT, tumor cell invasion and metastasis, which provide molecular insights for LPS-related pathogenesis and a basis for developing new strategies against metastasis in HCC. |

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 06 January 2015.
All research outputs
#20,248,338
of 22,776,824 outputs
Outputs from Tumor Biology
#1,834
of 2,622 outputs
Outputs of similar age
#192,539
of 228,668 outputs
Outputs of similar age from Tumor Biology
#73
of 111 outputs
Altmetric has tracked 22,776,824 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 228,668 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 111 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.
