Additionally, ZEB1 levels efficiently identified metastatic cancer cells for values higher than 0.2675 a.u. Also in this case, the CDH5/CDH1 and CDH1/ZEB ratios differentiate healthy from metastatic cancer cells for a.u. values higher than 0.06031 and >4.186, respectively. The gene discussed is ZEB1; the disease is metastatic malignant neoplasm.
