Figure 3. GO and KEGG enrichment analysis for POSTN in LUAD and LUSC. Volcano plot showing the correlations between POSTN and genes differentially expressed in LUAD (A). Heat maps showing genes positively and negatively correlated with POSTN in LUAD (Top50) (B, C). Volcano plot showing the correlations between POSTN and genes differentially expressed in LUSC (D). Heat maps showing genes positively and negatively related with POSTN in LUSC (Top50) (E, F). Enrichment terms in BP and KEGG enrichment pathways in LUAD and LUSC (G–J).
