At three weeks after injection, the expression of CXCL14 mRNA in tumours was determined by RT‐qPCR, which showed that CXCL14 expression was significantly up‐regulated in the tumour‐bearing mice injected with oe‐mCXCL14, but notably down‐regulated in those injected with sh‐mCXCL14 (Figure 3A). This evidence concerns the gene CXCL14 and neoplasm.
