Expression of P120ctn in non-Hodgkin's lymphoma and its significance / 中国实验血液学杂志

ABSTRACT

To evaluate the expression of P120ctn in non-Hodgkin's lymphoma (NHL) and to explore its clinical significance, immunohistochemistry stain method was applied to comparatively investigate the protein expression of P120ctn in paraffin-embedded lymph node tissue slices from 40 cases of NHL and 10 cases of reactive hyperplasia of lymph node. The results showed that P120ctn was not detected in reactive hyperplasia of lymph node, but was detected in 55% (22/40) cases of NHL. P120ctn expression increased with the tumor malignancy of NHL, there was a significant difference between the expression rates of P120ctn in low grade (16.7%, 2/12) and intermediate to high grade malignant (71.4%, 20/28) NHL (P < 0.001). Moreover, P120ctn was also detected in vascular endothelial cells of NHL. It is concluded that the level of P120ctn expression is closely related to the malignant grade of NHL, it suggests that P120ctn possibly plays an important role in the malignant proliferation of lymphoma with a certain significance in diagnosis and therapy of lymphoma.
