Abstract

Metastasis is the main cause of gastric Cancer (GC) related death and the underlying mechanisms still remain unclear. Collagen triple helix repeat containing 1 (CTHRC1) protein is known to be involved in tissue remodeling processes and closely associated with carcinogenesis and metastasis in solid tumors, but the functional role of CTHRC1 and its underlying mechanism with tumor metastasis in GC have not been fully illuminated. In the present study, CTHRC1 was highly expressed in tumor tissues and associated with poor prognosis of GC according to TCGA and GEO database. Functional studies revealed that CTHRC1 overexpression in GC significantly increased cell migration and invasion capacity. However, the promoting effects were abolished subsequent to silencing of CXCR4. In addition, CTHRC1 increased CXCR4 expression through upregulating HIF-1α expression, which eventually contributed to the promotion of cell migration and invasion. Inhibiting HIF-1α expression decreased CXCR4 expression and suppressed cell migration and invasion in GC. These results substantiated our hypothesis that HIF-1α/CXCR4 signaling pathway mediated the promoting effect of CTHRC1 on cell migration and invasion in GC.
