摘要: 目的 探讨核因子-κB(NF-κB)和c-myc在尖锐湿疣皮损角质形成细胞中的表达。方法 采用原位杂交方法检测尖锐湿疣50例,确定为HPV6/11阳性;采用免疫组化En Vision二步法检测50例尖锐湿疣患者皮损和25例正常人皮肤(包皮)中NF-κB和c-myc的表达及分布。结果 ①与正常人皮肤对照组相比,尖锐湿疣皮损角质形成细胞中NF-κB和c-myc的表达均有不同程度增强(前者U=6.286,P<0.01;后者U=4.356,P<0.01)。NF-κB表达主要分布于棘细胞层,阳性信号定位于胞浆。c-myc表达主要分布于表皮全层或棘细胞层和基底层,阳性信号定位于胞核。②尖锐湿疣皮损中,NF-κB与c-myc的表达呈正相关(r=0.89,P<0.01)。结论 在HPV6/11感染时,角质形成细胞中转录因子NF-κB和c-myc的表达增高,可能均参与HPV感染细胞增殖的调控。

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).Results ②The 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 significantly 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.
