Abstract:
Objective To investigate the expression and clinical significance of Rho GDP dissociation inhibitor 2 (Rho-GDI2) in pancreatic cancer.Methods Immunohistochemistry and RT-PCR were used to evaluate the expression of Rho-GDI2 in 60 pairs of pancreatic cancer tissues and adjacent pancreatic tissues,and its correlation with clinicopathological parameter of pancreatic cancer was also analyzed.Results The expressions of Rho-GDI2 mRNA were 0.661 ± 0.021 and 0.199 ± 0.023 in pancreatic cancer tissues and adjacent pancreatic tissues,and the positive rate of Rho-GDI2 protein expression were 73.3% (44/60) and 41.7% (25/60),the positive rate of Rho-GDI2 expression in pancreatic cancer tissues was higher than that of adjacent normal tissues,and the difference between the two groups was statistically significant (P < 0.01).The expression of Rho-GDI2 was strongly correlated with tumor size,differentiation,staging,lymph node metastasis,vascular invasion (P<0.05),but it was not associated with gender,age,tumor location (P >0.05).Conclusions Rho-GDI2 expression is up-regulated in pancreatic cancer,and is strongly correlated with the malignant biological behavior of pancreatic cancer.
