Abstract

Long non-coding RNAs (LncRNAs) have been identified as critical regulators in a variety of cancer types. Cancer susceptibility candidate 15 (CASC15), a lncRNA located at chromosome 6p22.3, has been discovered to participate in melanoma progression and phenotype switching. Nevertheless, the roles and molecular mechanisms of CASC15 in melanoma are far from being understood. We found that CASC15 expression was up-regulated in melanoma tissues and associated with advanced pathological stages. Function experiments displayed that CASC15 knockdown hindered proliferation, facilitated apoptosis and suppressed invasion, while CASC15 overexpression facilitated proliferation and invasion in melanoma cells. Further mechanistic analysis showed that CASC15 epigenetically silenced the expression of programmed cell death 4 (PDCD4) by recruiting EZH2 and increasing H3K27me3 level at the promoter region of PDCD4. Additionally, PDCD4 overexpression inhibited proliferation, enhanced apoptosis and decreased invasion of melanoma cells. Moreover, CASC15-knockdown-induced anti-cancer effects were abated by PDCD4 down-regulation. Furthermore, depletion of CASC15 blocked tumor growth of melanoma by up-regulating PDCD4 in vivo. CASC15 acts as an oncogene by negatively regulating PDCD4 expression via recruiting EZH2 and subsequently increasing H3K27me3 level. Together, our study indicates that CASC15/EZH2/PDCD4 may serve as a promising therapeutic target for melanoma intervention.

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 13 July 2018.
All research outputs
#10,530,244
of 13,218,736 outputs
Outputs from Cell & Bioscience
#185
of 311 outputs
Outputs of similar age
#198,755
of 266,391 outputs
Outputs of similar age from Cell & Bioscience
#2
of 6 outputs
Altmetric has tracked 13,218,736 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 311 research outputs from this source. They receive a mean Attention Score of 2.1. This one is in the 11th percentile – i.e., 11% 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 266,391 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 13th percentile – i.e., 13% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 6 others from the same source and published within six weeks on either side of this one. This one has scored higher than 4 of them.
