Correspondingly, we observed that the expression levels of NK cell-related chemokines were the highest in the combined treatment group, especially CCL7, CXCL10, CXCL11, and CX3CL1, which was consistent with the phenomenon that the proportion of NK cells was the highest in the combined treatment group, reflecting that they are responsible for the infiltration of NK cell into the tumor. The gene discussed is CCL7; the disease is neoplasm.
