Immunohistochemical staining showed that E‐cadherin expression was more in the Juglone‐treated tumor than in the DMSO treated tumor, and Vimentin expression was less than in the DMSO‐treated tumor (Figure 6c), indicating that downregulation of Pin1 expression inhibits EMT in cervical cancer in vitro. The gene discussed is CDH1; the disease is cervical carcinoma.
