Objective:
Cell division cycle 25C (CDC25C) is involved in the regulation of the G2/M phase transition and is associated with various cancers, including non-small cell lung cancer. We evaluated its prognostic value in lung adenocarcinoma (LUAD) based on data from The Cancer Genome Atlas (TCGA).
Methods:
Kruskal-Wallis test, Wilcoxon signed-rank test, and logistic regression were used to evaluate relationships between clinical-pathologic features and CDC25C expression. Cox regression analyses and the Kaplan-Meier method were used to evaluate factors contributing to prognosis. Gene set enrichment analysis (GSEA) was performed.
Results:
High CDC25C expression in LUAD was associated with a high tumor extent (odds ratio (OR) = 2.23 (1.52-3.29), P < 0.001), regional lymph node invasion (OR = 2.18 (1.48-3.22), P < 0.001), OR = advanced stage (OR = 2.47 (1.72-3.59), P < 0.001), and poor status (OR = 1.87 (1.19-2.96), P = 0.007). A univariate analysis showed that high CDC25C expression is associated with a short overall survival (OS) (HR: 1.873; 95% CI: 1.385-2.535; P < 0.001) and poor progression-free survival (HR: 1.503; 95% CI: 1.173-1.926; P = 0.0012). In a multivariate analysis, high CDC25C expression was associated with poor OS (HR = 2.193; CI: 1.394-3.452, P = 0.001). GSEA showed the enrichment of cell cycle, apoptosis, p53-dependent G1 DNA damage response, S-phase, mitotic M-M G1 phases, and FA-mediated cell death in the CDC25C high-expression phenotype.
Conclusions:
CDC25C predicts poor prognosis in LUAD and may function in cell cycle regulation and FAS-mediated apoptosis.
