ABSTRACT
Purpose To investigate the effects of chemotactic factor CCR4 on the abi1ity of pro1iferation,ce11 cyc1e,invasion,and mi-gration of human ga11b1adder cancer ce11. Methods Western b1ot was used to detect the expression 1eve1 of CCR4 in ga11b1adder carci-noma ce11s. Ga11b1adder carcinoma ce11s was infected by means of s1ow virus,the CCR4 gene si1encing was conducted using siRNA-CCR4 interference techno1ogy. Ga11b1adder carcinoma ce11s GBC-SD were divided into three groups( GBC-SD,GBC-SD/CCR4-RNAi and GBC-SD/contro1). CCL17,a 1igand of CCR4,was used to act on these three groups of ce11s. CCK8 method was used to detect the ce11 pro1iferation abi1ity of three groups. F1ow cytometry was used to test ce11 cyc1e. Tanswe11 assay was app1ied to detect ce11 migration and invasion abi1ity. Western b1ot was performed to detect the expression of its corresponding 1igands CCL17 and CCL22 proteins. Re-sults CCR4 gene si1ence did not inf1uence ce11 cyc1e and pro1iferation of ga11b1adder ce11 GBC-SD,but can significant1y inhibit GBC-SD ce11 invasion and movement abi1ity,CCR4 gene si1ence had no inf1uence on the expression of CCL17 and CCL22 gene in tumor ce11s. Conclusion Ga11b1adder carcinoma ce11s GBC-SD express chemokine receptor CCR4,chemokine receptor CCR4 can promote the invasion and metastasis of GBC-SD ce11s.
