In most of these neoplasms, as well as in testicular tumours and lymph node metastases of colorectal adenocarcinoma, increased dysadherin expression was correlated with reduced E-cadherin expression (Aoki et al, 2003; Sato et al, 2003; Shimamura et al, 2003, 2004; Wu et al, 2004; Batistatou et al, 2005, 2006). Here, FXYD5 is linked to neoplasm of testis.
