Objective.
The decrease of Elafin is associated with several inflammatory diseases.
Exogenous Elafin may be a treatment for IBD.
Little data has shown the expression of Elafin in patients of colorectal cancer.
Here, we tried to explore Elafin expression in human tissues of colorectal cancer.
Methods.
We examined the protein expression of Elafin in human tissues of adjacent nontumor and colorectal tumor by immunohistochemistry (IHC) or quantitative real-time polymerase chain reaction (qRT-PCR), then analyzed the clinical and RNA-seq data presented in The Cancer Genome Atlas (TCGA) database to confirm the relationship between Elafin levels and colorectal tumor.
Results.
Of the 88 paired samples, 68 colorectal cancer tissues indicated a high expression of Elafin compared with 52 matched adjacent noncancerous tissues.
And the mRNA levels of Elafin in 35 paired tissues showed a similar trend.
The RNA-seq and clinical data were available in 438 colorectal cancer tissues and 41 normal tissues in TCGA database.
The RNA-seq data showed that Elafin mRNA was upregulated about twofold in colorectal cancer samples as compared to adjacent noncancerous samples (176.42±402.13 vs.
96.75±150.07; P=0.208).
No statistically significant correlation was found between the Elafin expression and the age, gender, tumor invasive stage, lymph node metastasis, and distant metastasis both at the protein and mRNA levels.
However, the Elafin expression was correlated with clinical stage based on the AJCC guidelines at protein levels but not mRNA levels.
Conclusions.
Elafin was upregulated in patients of colorectal cancer, resulting to potential limitations for exogenous Elafin treatment.
