JUN and cancer: As for c‐Jun, it is a β‐Catenin target gene, plays a positive regulatory role in EMT of various tumour cells and inhibits the expression of c‐Jun, or its associated pathways would reduce cancer cell EMT process.48, 49, 50, 51 Considering that c‐Jun up‐regulation in ovarian cancer cells may lead to induction of EMT, we checked this protein to verify the regulatory role of Wnt/β‐catenin pathway in induction of EMT.
