The expression of E-cadherin, α-, β- and γ-catenin in node positive tumours was similar to node-negative tumours (copies/50 ng RNA, mean ± SD: E-cadherin node positive 35.5 ± 104.2, node negative 25.70 ± 35.13 p = 0.51; α-catenin node positive 26.60 ± 61.79, node negative 17.25 ± 23.08 p = 0.84, β-catenin node positive 0.0973 ± 0.2003, node negative 0.0895 ± 0.1686 p = 0.69, γ-catenin node positive 0.635 ± 4.004 node negative 0.622 ± 1.948 p = 0.55). The gene discussed is CDH1; the disease is neoplasm.
