- Abstract: Objective To investigate the expression levels of CXCL10 and CXCL12 in gallbladder carcinoma and their mechanism of action in tumor invasion.Methods Tumor tissue samples and adjacent tissue samples were collected from 56 patients with gallbladder carcinoma who underwent surgical resection in General Hospital of Central Theater Command from April 2020 to April 2023.RT-PCR was used to measure the mRNA expression levels of CXCL10 and CXCL12 in cancerous tissue and adjacent tissue,and the correlation of the mRNA expression levels of CXCL10 and CXCL12 in cancerous tissue with clinicopathological parameters was analyzed.The human gallbladder carcinoma cell line GBC-SD was used to construct gallbladder carcinoma cells with low expression of CXCL10 and CXCL12.CCK8 assay was used to observe the effect of low expression of CXCL10 and CXCL12 on the proliferation of gallbladder carcinoma cells,Transwell assay was used to observe the effect of low expression of CXCL10 and CXCL12 on the invasion ability of gallbladder carcinoma cells,and Western blot was used to measure the expression of the PI3K/Akt pathway in gallbladder carcinoma cells.The paired t-test or independent-samples t-test was used for comparison of measurement data between two groups;an analysis of variance was used for comparison between multiple groups,and the least significant difference t-test was used for further comparison between two groups.Results In the patients with gallbladder carcinoma,the relative mRNA expression levels of CXCL10 and CXCL12 in cancerous tissue were significantly higher than those in adjacent tissue(CXCL10:1.857±0.315 vs 1.024±0.203,t=16.342,P<0.05;CXCL12:2.038±0.374 vs 1.064±0.221,t=16.778,P<0.05).There were significant differences in the relative mRNA expression levels of CXCL10 and CXCL12 between the patients with different TNM stages,presence or absence of lymph node metastasis or distant metastasis,and tumor diameters(all P<0.05).Compared with the control group and the si-RNA group,the si-CXCL10 group had significantly lower relative mRNA and protein expression levels of CXCL10 and CXCL12,CCK-8 absorbance values,number of cell migration,and protein expression levels of p-PI3K and p-Akt(all P<0.05).Conclusion There are increases in the expression of CXCL10 and CXCL12 in gallbladder carcinoma tissue,and the proliferation and invasion of gallbladder carcinoma cells are significantly inhibited after inhibition of the expression of CXCL10 and CXCL12,which might be associated with the inhibition of the phosphorylation of the PI3K/Akt pathway.
