The analysis identified DEGs that were mainly enriched in biological pathways such as molecular mechanism of cancer, mitochondrial dysfunction, protein ubiquitination, oxidative phosphorylation, sirtuin signaling, EIF2 signaling, glucocorticoid receptor signaling, RAR activation, aryl hydrocarbon receptor signaling, tight junction signaling, and death receptor signaling pathways. The gene discussed is AHR; the disease is cancer.
