S179 Higher Expression of CTHRC1 in Tumor Tissues Is Associated With Poor Prognosis in Colorectal Cancer: A Bioinformatical Analysis

Abstract Background: Genetic alterations play an important role in the progression of colorectal cancer (CRC). Identifying new biomarkers to assess the prognosis of patients with CRC is critical. Cartilage Intermediate Layer Protein 2 (CILP2) gene, screened from the TCGA database by bioinformatics, may be closely related to the progression of CRC. CILP2 was barely reported with clinical features of tumors.Materials and methods: Clinical information and RNA-seq data were derived from the TCGA colorectal carcinoma cohort. CILP2 expression at mRNA level was estimated by bioinformatical analysis of TCGA cases. Tissue microarray (TMA) was constructed containing paraffin-embedded 64 pairs of CRC and matched adjacent normal tissues. The expression at the protein level was detected in 64 pairs of CRC and matched adjacent normal tissues by immunohistochemical analysis. CILP2 expression level and its clinical value were estimated by bioinformatical analysis with linear and logistic regression. Survival analysis was performed between high and low groups of CILP2 expression by Cox regression analysis, and the P-value was calculated by the log-rank test. Kaplan-Meier curves were tested by the log-rank test.Results: CILP2 was statistically significantly higher expressed in the CRC tissues when compared with paired adjacent normal tissues in the TCGA cohort (P<0.001) and in the TMA cohort (P=0.001). Also, CILP2 high-expression was strongly correlated with T3/4 stage (P=0.001), N1/2/3 stage (P=0.005), M1 stage (P=0.048), and higher clinical stage (UICC 2010 stage) (P<0.001) in TCGA cohort, and also positively associated with T3/4 stage (P=0.022) and higher clinical stage (UICC 2010 stage) (P=0.03) in TMA cohort. Furthermore, CILP2 overexpression predicted poor prognosis and could be as an independent prognostic factor (P=0.003).Conclusion: We revealed that CILP2 is associated with advanced stages and could play a role as an independent predictor of poor survival in CRC.

Abstract Background Cartilage Intermediate Layer Protein 2 (CILP2), a glycoprotein with mutations associated with abnormal blood lipid concentrations in normal and cardiovascular diseases patients, was barely reported with clinical features of tumors. We evaluated the role of CILP2 among all stages and histology in colorectal cancer (CRC) in the Cancer Genome Altas (TCGA), and furtherly verified using immunohistochemistry assay within human CRC tissues. Materials and methods Clinical information and RNA-seq data were derived from TCGA colorectal carcinoma cohort. CILP2 expression at mRNA level was estimated by bioinformatical analysis of TCGA cases.

Novel Biomarkers

Colorectal cancer (CRC) is the leading cause of cancer death worldwide and its incidence is increasing. In most patients with CRC, the PI3K/AKT signaling axis is over-activated. Regulatory oncogenic or tumor suppressor microRNAs (miRNAs) for PI3K/AKT signaling regulate cell proliferation, migration, invasion, angiogenesis, as well as resistance to chemo-/radio-therapy in colorectal cancer tumor tissues. Thus, regulatory miRNAs of PI3K/AKT/mTOR signaling represent novel biomarkers for new patient diagnosis and obtaining clinically invaluable information from post-treatment CRC patients for improving therapeutic strategies. This review summarizes the current knowledge of miRNAs’ regulatory roles of PI3K/AKT signaling in CRC pathogenesis.
