Activation of the Dickkopf1-CKAP4 pathway is associated with poor prognosis of esophageal cancer and anti-CKAP4 antibody may be a new therapeutic drug.
p63 is a member of the p53 protein family and plays a crucial role in epithelial development. p63 is expressed in many types of tumors including esophageal cancer; however, its function in cancer is controversial and its role in esophageal cancer has not been clearly established.
To explore the penetrance of p63 in esophageal cancer, we analyzed p63 expression in squamous cell carcinomas, adjacent dysplasia and histologically normal mucosa of the esophagus by combination of immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR).
