OBJECTIVE: To investigate the expression and correlation of Skp2 and p27kipl in non-Hodgkin's lymphoma.
METHODS: The expression of Skp2, p27(kip1) and Ki-67 (the proliferation index)were detected in sections of 92 cases of non-Hodgkin's lymphoma (NHL) and 14 cases of reactive lymph nodes by immunohistochemistry and histopathology. The expression of Skp2 and p27(kip1) in 4 NHL cell lines were detected by Western blot.
RESULTS: The expression of Skp2 in NHL cases were significantly higher than that in reactive lymph nodes (except the germinal centers), positively correlated with proliferation activity, and an increasing tumor aggressiveness was associated with the increased expression of Skp2. The expression of p27(kip1) protein in NHL cases were significantly lower than that in reactive lymph nodes (except the germinal centers), negatively correlated with proliferation activity, and an increasing tumor aggressiveness was associated with decreased expression of p27(kip1). The statistical analysis indicated that there was no obvious correlation between Skp2 and p27(kip1) expression in NHL tissues.
CONCLUSION: The higher expression of Skp2 and lower expression of p27(kip1) in NHL tissues may play a role in the tumorigenesis and development of NHL.
