摘要
Objective:To study the correlation of Krüppel-like factor 9 (KLF9) expressions in pancreatic cancer tissue with serum tumor markers and focal cell invasion.Methods: A total of 58 patients with pancreatic cancer treated in our hospital between June 2012 and May 2016 were collected, the expression of KLF9 in pancreatic cancer tissues and paracancerous tissues were measured and then patients were further divided into high KLF9 expression group and low KLF9 expression group, 29 cases in each group. Serum tumor marker levels as well as invasion gene and tumor suppressor gene expression in tumor tissue were compared between patients with different KLF9 expression.Results: KLF9 expression in pancreatic cancer tissue was significantly lower than that in paracancerous tissue;serum tumor markers CA19-9, CA242, CA50 and CEA levels of low KLF9 expression group were higher than those of high KLF9 expression group;focal invasion genes DKK-1, GSK3β and HOXB7 mRNA expression of low KLF9 expression group were higher than those of high KLF9 expression group while tumor suppressor genes Bach2, SIRT3, DPC4 and Kiss-1 mRNA expression were lower than those of high KLF9 expression group.Conclusion: The expression of KLF9 decreases in pancreatic cancer tissues, and the expression of KLF9 is negatively correlated with the malignant degree of tumor.
