Our discovery that the ΔNp63α dependent expression of FAT2 and Slug is necessary for lung SCC migration, and that ΔNp63α is positively correlated with FAT2 and Slug expression in lung cancer patient tumors, suggested that the expression of this ΔNp63α dependent pathway may correlate with non-small cell lung cancer (NSCLC) patient outcome. This evidence concerns the gene SNAI2 and lung cancer.
