The F-box protein Skp2 (S-phase kinase associated protein 2) positively regulates the G1-S transition by controlling the cell cycle inhibitor p27Kip1. The p42/p44 mitogen-activated protein (MAP) kinase activation is also necessary for the cell cycle progression. p27Kip1 acts as a negative regulator of the cell cycle by inhibiting the activity of cyclin/cdk complexes during G0 and G1. RT-PCR, Western blotting and immunohistochemical staining were used to assay their relationship with cervical lesion development. In RT-PCR and western blotting, Skp2 mRNA and protein were expressed mostly in carcinoma tissues. At Fisher¡¦s exact test showed that Skp2, p27Kip1 and p42/p44 MAP Kinase are strongly associated with disease progession respectively (P < 0.0001, P < 0.0001, P = 0.0043). We also found a postive correlation between the expression of Skp2 and p42/p44 MAP Kinase (P = 0.0097).
