- Abstract: Aim To investigate the role and mecha-nism of CXC chemokine receptor 3(CXCR3)in hepa-toblastoma(HB).Methods The expression of CX-CR3 was detected by immunohistochemical and West-ern blot in 16 cases of HB tissue and adjacent normal liver tissue.The HB cells(Huh-6 and HepT1)were transfected with Con-shRNA,CXCR3-shRNA1,and CXCR3-shRNA2,respectively,and then divided into the Con-shRNA group,CXCR3-shRNA1 group,and CXCR3-shRNA2 group.Cell proliferation was detected by CCK-8 assay and EdU staining.Cell migration and invasion were detected by scratch and Transwell as-says.The expressions of β-catenin,c-Myc,cyclin D1,MMP-7 and MMP-9 were detected by Western blot.The tumor formation and tumor volume in each group were assessed using nude mouse xenograft tumor model,while the expressions of MMP-9 and Ki67 in tumor tissue were examined by immunohistochemistry.Results The expression of CXCR3 was up-regulated in HB tissue(P＜0.01).Compared to the Con-shR-NA group,the viability,proliferation,migration and invasion of Huh-6 and HepT1 cells in the CXCR3-shR-NA1 and CXCR3-shRNA2 groups were reduced(P＜0.01),the expressions of the Wnt/β-catenin signaling pathway related proteins were attenuated(P＜0.01),the tumor grew slowly and the volume was significantly reduced(P＜0.01),and the expressions of MMP-9 and Ki67 in tumor tissue decreased(P＜0.01).Con-clusions Downregulation of CXCR3 hinders the pro-liferation and migration of HB cells,potentially as-cribed to the attenuation of Wnt/β-catenin signaling regulation.
