Decorin has been found to have a tumour suppressor role in several studies (Csordas et al, 2000; Iozzo et al, 1999; Santra et al, 2000), but other works (Benet et al, 2012; Dil & Banerjee, 2011; Zafiropoulos et al, 2008) and ours correlate decorin with increased tumour invasion and metastasis. Here, DCN is linked to neoplasm.
