Abstract

Prior study indicates that abnormal protein expression and functional changes in the development and progression of colorectal cancer is related to gene expression. The aim of this study was to construct an interference plasmid targeting the Ep-CAM gene and to investigate its effects on the proliferation of colorectal cancer cells. In this study, HT-29 and HCT-116 colorectal cancer cell lines were selected as cell models. The double-stranded micro (mi)RNA oligo was inserted into the pcDNATM6.2-GW/EmGFPmiR vector, which is an expression of miRNA. Lipofectamine™ 2000 was used to transfer plasmid into the empty plasmid group (transfected pcDNATM6.2-GW/EmGFPmiR-neg) and the interference group (transfected pcDNATM6.2-GW/EmGFPmiR-Ep-CAM-1), respectively. Meanwhile, the nontransferred HT-29 and HCT-116 acts as the blank control group. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the transfection efficiency. Western blot was used to detect Ep-CAM protein expression. The cell proliferation in each group was detected by using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The results indicated that the Ep-CAM messenger (m)RNA expression in the interference group was lower significantly compared with that of the empty plasmid group and control group (P<0.01). Western blot analysis results showed that Ep-CAM protein expression was significantly lower in interference group compared with that of the empty plasmid group and the control group (P<0.01). MTT assay results demonstrated that the proliferation ability of cells in the interference group was significantly inhibited compared with the two other groups (P<0.05). Silencing of Ep-CAM can significantly inhibit the proliferation of colorectal cancer cells.

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 02 June 2015.
All research outputs
#18,409,030
of 22,803,211 outputs
Outputs from Drug Design, Development and Therapy
#1,279
of 2,083 outputs
Outputs of similar age
#192,630
of 264,354 outputs
Outputs of similar age from Drug Design, Development and Therapy
#61
of 98 outputs
Altmetric has tracked 22,803,211 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 2,083 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.2. This one is in the 24th percentile – i.e., 24% 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 264,354 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 98 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
