Cadherin 17 (CDH17, LI‐cadherin), another RGD cadherin [8], appears to be highly expressed in mucinous ovarian cancers, according to the Human Protein Atlas database (www.proteinatlas.org/ENSG00000079112‐CDH17/pathology/ovarian+cancer#ihc) [9], but has yet to be further characterized in ovarian cancer. This evidence concerns the gene CDH17 and mucinous ovarian cancer.
