In this study, the researchers studied the CC chemokine receptor expression level in GC patients and discovered that six genes were expressed differentially in gastric tumor tissues in comparison to the normal tissues (the results indicated that CCR1, CCR4, CCR5, and CCR8 genes were upregulated, whereas the CCR6 and CCR10 genes were downregulated). The gene discussed is CCR8; the disease is gastric neoplasm.
