EMMPRIN silencing inhibits the metastatic nodes in the lungs. a Metastasis assay by tail vein injection of shRNA transfected 143B cells in BALB/c mice. Lungs were excised for examination at 8 weeks post-injection. The number of lung metastatic nodes was assessed by Bouin’s stain. Arrows indicate visible lung surface metastases. b Tumor volume and c Number of nodules at the study end point. d 143B cells were transfected with mock shRNA and EMMPRIN shRNA for 48 h, and cell lysates were analyzed by western blot using anti-EMMPRIN antibody. β-actin was used as a loading control. e Microscope images by H&E staining show that EMMPRIN silencing significantly inhibits the lung metastatic nodes after inoculation with 143B, 2 × 105 cells/ 200 ul. *, p < 0.05 compared with cells transfected with control siRNA. Scale bar, 100 μm. Original magnification, × 10 and × 40
