POSTN and cancer: As a result, although POSTN (1–4) KO mice significantly increased primary cancer growth (p < 0.05) and suppressed lung metastasis (p < 0.05) in Figure 3F, 17KO mice significantly suppressed primary cancer growth (p < 0.05) and lung metastasis (p < 0.05) compared to wild-type mice (Figure 3D,E).
