The data in Figure 6 clearly demonstrate that silencing Snail but not its Slug associated family member in A2780 cells completely abrogated not only the robust and bloody tumor vascularization (Figure 6B), but also tumor growth (Figure 6A) and metastatic spread to the lung (Figure 7B) in RAGxCγ double mutant mice. This evidence concerns the gene SNAI2 and neoplasm.
