GCC2 and lung carcinoma: All the enriched key pathways were identified according to significant differences (|NES|>1, P-value <0.05, and FDR q value <0.25) in the enrichment of genes in the MSigDB collection (C2.all.v6.2.symbols), including lung cancer poor survival (Figure 4E), metastasis (Figure 4F), epithelial mesenchymal transition (EMT, Figure 4G), proliferation (Figure 4H), and tumorigenesis (Figure 4I) in the high GCC2-AS1 expression phenotype, suggesting that GCC2-AS1 might play a role in LUAD progression.
