ABSTRACT
Objective To investigate the expression of NF-k B and c-myc in keratinocytes of HPV infected condyloma acuminata (CA) lesions.Methods Fifty cases of HPV 6/11 positive CA were diagnosed by in situ hybridization.The expression and distribution of NF-k B and c-myc were detected by immunohistochemistry technique (EnVision) with CA lesions and 25 normal human skins (foreskins). Results②The expression of NF-k B and c-myc was significantly higher in keratinocytes of CA lesions than those of normal controls (P＜0.01 ).NF-k B was mainly expressed in spinous layers of CA lesions, and most positive signals located significantly in the cytoplasm.C-myc was mainly expressed in the whole epidermis or in spinous and basal layers in CA lesions,and positive signals located in the nuclei.②There was a positive correlation between the expression of NF-k B and c-myc in CA lesions (r=0.89,P＜0.01).Conclusions The study demonstrates that the expression of both NF-k B and c-myc is significant- ly higher in HPV 6/11 positive CA than in normal skin.The data suggest that transcriptional factor NF-k B and c-myc may play a role in the regulation of proliferation of HPV 6/11 infected cells.
