In summary, after radiation and SN38 treatment, we found that most significant up- or down-regulation and interactions of 8 miRNAs (let-7f-5p, miR-455-3p, miR-98, miR-155-5p, miR-1, miR-127-5p, miR-142-5p, miR-202-5p), 7 cytokines (IL-1β, IL-4, IL-6, IL-10, IFN- γ, VEGF, TNF- α) and 2 chemokines (IL-8, MIP-1-α) were dependent on p53 status in colon cancer cells. The gene discussed is CXCL8; the disease is colonic neoplasm.
