Identification of Potential Key Genes and Prognostic Biomarkers of Lung Cancer Based on Bioinformatics

Figure 3

Validation and visualization of four essential core genes (CHEK1, CCNB1, CCNB2, and CDK1) in datasets GSE33532 and GSE151102. The heatmap was established based on the gene expression profiles in the information sets GSE151102 (a) and GSE33532 (b). The expression levels of DEGs are represented by different colors: red, high expression; green, low expression; blue, normal tissue; orange, lung cancer tissue.
