Construction and validation of a novel prediction system for detection of overall survival in lung cancer patients

Figure 5 Expression and survival curve of 11 genes in The Cancer Genome Atlas dataset and the validation of the 11 genes’ expression by immunohistochemistry and quantitative real-time polymerase chain reaction analyses. A: Expression of 11 genes in The Cancer Genome Atlas (TCGA) dataset; B: Correlation of 11 genes and the survival rate in the TCGA dataset; C: Expression profile of 11 genes in tumor tissues obtained from the Protein Atlas database; D: Quantitative real-time polymerase chain reaction analysis indicating the expression of 11 genes in lung cancer cell lines when compared with that in normal lung bronchial cells. ^aP < 0.05, ^bP < 0.01.
