CDH1 and cancer: As elevated E-cadherin is known to suppress invasive behaviour of cancer cells and to negatively regulate MMP expression, including that of MT1 (Ara et al, 2000; Takahashi et al, 2002; Nawrocki-Raby et al, 2003a, 2003b; Hazan et al, 2004; Hlubek et al, 2004; Munshi and Stack, 2006), we also assessed cadherin expression in these cell lines.
