VIM and acromegaly: Thus, we analyzed the expression of a subset of EMT-related genes, including the epithelial marker ESRP1; the mesenchymal markers vimentin, N-cadherin, SNAI1, SNAI2, and TWIST1 (the last three being transcription factors); and RORC, which previously has been related to E-cadherin and EMT in acromegaly [31].
