Expression of nm23-H1 and PCNA in human glioma cells / 西安交通大学学报(医学版)

ABSTRACT

Objective To investigate the ex pr ession of nm23-H1 protein and proliferating cell nuclear antigen (PCNA) in huma n glioma cells. Methods Expression of nm23-H1 and PCNA in 53 br ain gliomas were detected by immunohistochemistry. Results The immunohistochemistry staini ng of nm23-H1 protein in low-grade astrocytomas (grades Ⅰ and Ⅱ) was significantly higher than that in high-grade astrocytomas (grades Ⅲ and Ⅳ). The immunohistochemistry staining of PCNA in high-grade astrocytomas was s ignificantly higher than that in low-grade astrocytomas. Conclusion The lower expression of nm23-H1 protein and the higher expression of PCNA are correlated with the pathological grade of glioma cells. The expression of nm23-H1 may be used as a hopeful marker for predicting the metastastic potential of gliomas.
