| Abstract |
Glioblastoma has been reported as one of the leading causes of cancer-related death, and some factors including oncogenic genes and environments are involved in tumorigenesis. MicroRNAs (miRNAs) act as a kind of small and noncoding RNA, which can target the downstream molecules. Emerging reports demonstrate that microRNAs regulate the initiation and progression of different cancers. In the present study, we conducted in vitro experiment as well as clinical studies in a cohort of 20 glioblastoma samples. We demonstrated that miR-622 expression was lower in tumor tissues and cells, when compared to normal brain tissues and normal human astrocyte (NHA) cells, while K-Ras messenger RNA (mRNA) and protein showed the opposite expression profile. Overexpression of miR-622 suppressed tumor cell proliferation, migration, and invasion of A172, U87, and U251 cells. Accordingly, the proliferating cell nuclear antigen (PCNA), matrix metallopeptidase 2 (MMP2), and MMP9 expressions were also decreased due to miR-622 overexpression. Importantly, we discovered that wild Kirsten rat sarcoma (K-Ras) was a direct target of miR-622, which decreased the expression of K-Ras protein in A172, U87, and U251 cells. In conclusion, upregulated miRNA-622 inhibited cell proliferation, migration, and invasion via repressing K-Ras in the progression of glioblastoma, and miR-622-K-Ras pathway can be recommended as a potential target for treatment of glioblastoma. |

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 26 November 2015.
All research outputs
#17,778,101
of 22,834,308 outputs
Outputs from Tumor Biology
#1,219
of 2,622 outputs
Outputs of similar age
#262,174
of 386,225 outputs
Outputs of similar age from Tumor Biology
#91
of 316 outputs
Altmetric has tracked 22,834,308 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 2,622 research outputs from this source. They receive a mean Attention Score of 2.2. 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 386,225 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 316 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
