Fig. 5: Gene expression profile revealed some extent of similarity of the same histologic components across different patients.

a Principal component analysis (PCA) of all histologic components based on gene expression data. b Heatmap of the top 500 most variable genes across the samples clustered by both genes and the samples. c Commonly upregulated and downregulated pathways comparing SCLC with LUAD across public datasets and in-house dataset. d Commonly upregulated and downregulated pathways comparing LCNEC with LUAD across public datasets and in-house dataset.
