Abstract:
The study was aimed to explore the possible roles of survivin and P63 protein in the development and progression of B cell non-Hodgkin's lymphoma (B-NHL) and their relation with cell apoptosis and proliferation. TdT-mediated dUTP nick end labeling (TUNEL) and immunohistochemistry were used to detect the survivin and P63 protein expression, cell apoptosis and proliferating cell nuclear antigen (PCNA) level in 43 cases of B-NHL and 10 cases of reactive hyperplasia lymphoid (RHL) tissues. The results indicated that the positive rates of survivin and P63 protein expression were 69.8% (30/43) and 82.7% (30/43) respectively. The expression of survivin and P63 protein was 10% (1/10) and 40% (4/10) in RHL tissues of 10 cases. The expression of survivin in aggression B-NHL was higher than that in indolent B-NHL (83.3% vs 46.2%, P < 0.01). The expression of P63 proteins in aggressive B-NHL was higher than that in indolent B-NHL (86.7% vs 76.9%, P > 0.05). Apoptotic index (AI) and proliferation index (PI) correlated positively with expression of survivin (r = 0.429, P < 0.01; r = 0.348, P < 0.01), and so do with expression of P63 proteins (r = 0.451, P < 0.01; r = 0.369, P < 0.05). In addition, AI and PI were positively related (r = 0.598, P < 0.001). It is concluded that survivin may participate in the regulation mechanism of B-NHL cell apoptosis and proliferation, P63 as an oncogene enhances proliferation and takes part in the development of B-NHL. There may be a close relationship between survivin and P63 protein in the regulation of lymphocyte proliferative kinetics.
