SPOCK1 promotes tumor invasion and metastasis in vivo by inducing EMT. (A) An in vivo metastasis assay was performed to evaluate the effect of Lv-shSPOCK1 cells on tumor metastasis. Mice that received SPOCK1-depleted NOZ cells exhibited little ascites at 4Â weeks after implantation. (B) The tumor incidence rate during the 4-week observation period. (C) Immunohistochemical staining of SPOCK1, E-cadherin, and vimentin in tumor tissues of the peritoneal metastasis model.
