ABSTRACT
Objective To investigate the expression and significance of signal pathway Wnt/β-catenin in prostate cancer stem cells.Methods Prostate cancer tissues,hyperplasia prostate tissues and normal prostate tissues were collected,then prostate cancer stem cells were selected from cell suspension in the culture system of serum-free medium by magnetic activated cell sorting system.Immunohistochemical SP test,RT-PCR and Western blot were applied to test the expression of Wnt and β-Catenin mRNA or protein in prostate cancer stem cells,hyperplasia prostate tissues and normal prostate tissues.Results The protein expression of Wnt and β-Catenin was higher in prostate cancer tissues compared with that in hyperplasia prostate tissues and normal prostate tissues;mRNA expression of Wnt and β-Catenin was higher in prostate cancer stem cells (4.57±0.83,3.93±0.78) than in hyperplasia prostate tissues (1.32±0.35,1.48±0.44) and normal prostate tissues (1.00±0.12,1.00±0.11),and the difference was statistically significant (F=13.287,12.648,P=0.000).Protein expression of Wnt and β-Catenin was higher in prostate cancer stem cells(0.87±0.10,1.12±0.23) than in hyperplasia prostate tissues(0.39±0.08,0.64±±0.11) and normal prostate tissues (0.33±0.09,0.45±0.10),and the difference was statistically significant (F=16.625,14.417,P=0.000).Conclusion Signal pathway Wnt/β-catenin is stimulated abnormally in prostate cancer stem cells,causing the occurrence of prostate cancer,providing a new research direction for treatment of prostate cancer.
