Recent studies showed that YAP is expressed in pancreas tissues in pancreatic ductal adenocarcinoma (PDAC) patients and experimental models of PDAC, with YAP largely found in cancer cells and pancreatic stellate cells (PaSC) in the stroma.
Depletion of yes-associated protein 1 inhibited the invasion of pancreatic ductal adenocarcinoma cells via downregulation of Vimentin, matrix metalloproteinase-2, and matrix metalloproteinase-13, and upregulation of E-cadherin.
In our study, YAP expression was identified by immunohistochemistry and quantitative Real-time PCR from 45 pairs of human pancreatic ductal adenocarcinoma (PDAC) tissues and their adjacent non-tumor samples.
