TP53 and small cell lung carcinoma: KEGG pathway enrichment showed that many genes co-expressed with NCAPG were involved in the cell cycle, DNA replication, the Fanconi anemia pathway, oocyte meiosis, cellular senescence, human T cell leukemia virus 1 infection, homologous recombination, mismatch repair, progesterone-mediated oocyte maturation, the p53 signaling pathway, base excision repair, RNA transport, nucleotide excision repair, pyrimidine metabolism, viral carcinogenesis, and small cell lung cancer (Figure 5F).
