This study used GO and KEGG enrichment analyses to elucidate the biological functions of DEARGs, which were mainly enriched in inflammatory cell activation, cell chemotaxis, the FoxO signaling path, autophagy, cellular senescence, TNF signal channel, longevity controlling pathway, AMPK signaling path, and non-small cell lung cancer. The gene discussed is TNF; the disease is non-small cell lung carcinoma.
