Abstract:
Objective:To study the expression and prognostic impact of secretory carrier membrane protein 3 (SCAMP3) in hepatocellular carcinoma (HCC) and its gene set enrichment analysis.Methods:SCAMP3 expression and its prognosis were analyzed using The Cancer Genome Atlas (TCGA) database. The cancer tissue and paracancerous tissue were collected from four patients with HCC undergoing surgery in Lishui Central Hospital to detect the expression of SCAMP3. Based on TCGA database, univariate and multivariate Cox regression was performed to analyze the relevance of SCAMP3 with prognosis of HCC. Gene set enrichment analysis was utilized to clarify the biological role of SCAMP3.Results:In TCGA database, SCAMP3 expression was higher in HCC tissues than that in normal liver tissues ( Z=-8.38, P<0.001). Patients were divided into the low-expression group ( n=185) and high-expression group ( n=185) based on the median SCAMP3 expression, and the overall survival rate was lower in patients with high SCAMP3 expression. In our four patients. The expression of SCAMP3 mRNA and protein in cancer tissues was higher than that in paracancerous tissues ( t=8.55, 6.24, both P<0.001). In multivariate Cox regression analysis, the higher SCAMP3 expression was associated with a higher risk of death ( HR=1.466, 95% CI: 1.143-1.881, P<0.001). Gene set enrichment analysis in patients with high SCAMP3 expression, the coagulation cascade and three signaling pathways involving the complements, retinol metabolism, and peroxisome proliferator-activated receptor were identified. Conclusion:SCAMP3 expression elevated in HCC, patients with a higher expression of SCAMP3 might have a worse prognosis. High SCAMP3 expression is a risk factor for the survival of patients with HCC. High SCAMP3 expression is associated with the coagulation cascade and the complements, retinoid metabolism, and peroxisome proliferator-activated receptor pathways.
