Fig. 7: Silencing of TRAIP inhibits tumor growth and metastasis in nude mice.

A ShCtrl and ShTRAIP-1 MDA-MB-231 cells were subcutaneously implanted into 5-week-old female BABL/c nude mice. The tumor volume was measured using the following formula: volume (mm3) = (width2×length)/2. B Six-week-old female nude BALB/c mice were injected with 1 × 106 ShCtrl or ShTRAIP-1 MDA-MB-231 cells via the tail vein. Luciferase-signal and lung weight were exhibited. C Images of lung metastasis and H&E staining (left × 200; right ×400; upper: ShCtrl group; lower: ShTRAIP-1 group) are shown. (**P < 0.01, *P < 0.05).
