Enrichment functional analysis of DEGs using the R package ClusterProfiler revealed upregulated DEGs to be enriched in 6 functional pathways involved in NSCLC-related biological processes, including cell cycle, biosynthesis of amino acids, carbon metabolism, P53 signaling pathway, Fanconi anemia pathway, and DNA replication (Figure 3C). The gene discussed is TP53; the disease is non-small cell lung carcinoma.
