CCR7 and gastric cancer: The significant increase in the CCR-7 transcriptional level in the MGC-803-pCMV6-RNF180-DCpG+97 cell line (following the MGC-803-pCMV6-RNF180-DCpG+102 cell line) indicated that the CpG+97 island in RNF180 DNA promoter was the other potential trigger point that promoted the chemotactic movement in the migration and invasion of gastric cancer cells.
