Meanwhile, we found that the concentrations of CXCL6 (Figure 2E) and CXCL8 (Figure 2F) in tumor tissue culture supernatants (TTCS) or tumor tissues were obviously augmented in contrast with those in non‐tumor tissue culture supernatants (NTCS) or non‐tumor tissues. The gene discussed is CXCL8; the disease is neoplasm.
