GO/KEGG enrichment analysis proved that the relevant mechanism may involve the humoral immune response, immunoglobulin complex, antigen binding, B-cell-mediated immunity, complement activation immunoglobulin receptor binding, cytokine receptor interaction, external side of the plasma membrane, PI3K-Akt signaling pathway, transcription misregulation in cancer, systemic lupus erythematosus, ECM-receptor interaction, and IL-17 signaling pathway. The gene discussed is AKT1; the disease is cancer.
