To determine the roles of TAZ in pancreatic cancer development and progression, we first analyzed the expression of TAZ in a pancreatic cancer tissue microarray (TMA), which contained 57 primary pancreatic tumor, 10 tumor-adjacent normal pancreatic tissue, and 10 normal pancreatic tissue specimens, using immunohistochemistry. The gene discussed is WWTR1; the disease is familial pancreatic carcinoma.
