50 meiotic genes associated with prognosis of lung adenocarcinoma were identified. A K-means clustering analysis of meiosis related genes was performed using the expression profile of lung adenocarcinoma in TCGA; heatmap displaying consensus clustering with the robust classification (k = 2). B PCA plot proved the feasibility of grouping. C tSNE plot proved the feasibility of grouping. D Kaplan-Meier curves of OS between clusters. Log-rank test p values are shown. E A PPI network was constructed based on 50 prognostic-related genes obtained by univariate regression analysis
