| Abstract |
Colorectal cancer (CRC) is a multistep process based on the accumulation of somatic mutations in genes such as APC and KRAS. Data on the presence of mutations in KRAS gene in CRC and its relationship with clinicopathological parameters and expression of genes involved in tumor progression are scarce. We unbiasedly examined the KRAS status in samples from 99 patients and its correlation with clinicopathological parameters such as age, sex, tumor location, lymph node metastasis, tumor stage, tumor grade, and vascular invasion. Consistent with reports of other researchers, 38.4 % of our samples harbored KRAS mutation in their genomes with preferential mutation in codon 12 (89.4 %). Nevertheless, unlike previous reports, we were not able to correlate KRAS status with clinicopathological parameters (P > 0.05) except for vascular invasion. Patients with KRAS mutation have more vascular invasion compared with patient having wild-type KRAS. Next, we investigated the expression of two tumor suppressor genes, factor-inhibiting hypoxia-inducible factor 1 (FIH-1) and suppressor of cytokine signaling (SOCS3), in both KRAS mutant and wild-type groups and looked for any correlation between their expression and clinicopathological parameters. Although the expression of both genes was not regular, none of the clinicopathological parameters were associated with the expressions of FIH-1 and SOCS3 at mRNA level (P > 0.05). However, decline in FIH-1 expression at protein level in KRAS mutant group was correlated with stage IV and grade 2 of tumor (P ≤ 0.05). Our results demonstrated that there is no or low correlation between KRAS status, FIH-1, and SOCS3 expression with epidemiologic and clinicpathological characteristics in CRC. |

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 11 January 2016.
All research outputs
#20,300,248
of 22,837,982 outputs
Outputs from Tumor Biology
#1,834
of 2,622 outputs
Outputs of similar age
#330,760
of 393,971 outputs
Outputs of similar age from Tumor Biology
#177
of 278 outputs
Altmetric has tracked 22,837,982 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 393,971 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 278 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.
