CXCL3 and neoplasm: In the meantime, we have conducted some internal validations using expression datasets, such as validating the core gene CXCL3. Expression analyses of CXCL3 showed that its expression was significantly higher in CC tumor tissues. These results were consistent with those obtained from the external validation datasets GSE52930,GSE9750 and GSE3514 (Fig. 5D–F).
