Although CDH1 gene expression levels are similar between normal and keloid keratinocytes, keloids express decreased protein levels of E-cadherin (188, 190), in line with cadherin switching from E-cadherin to mesenchymal markers such as N-cadherin (191), fibronectin-1, vimentin, and cadherin-11. The gene discussed is FN1; the disease is keloid.
