目的:探讨宫颈病变组织内蛋白激酶R(PKR)、核因子(NF)-κB p65的表达及磷酸化的意义,高危型人乳头状瘤病毒(hsHPV)对两者表达及磷酸化的影响,以及三者的关系。方法以67例宫颈癌、149例宫颈上皮内瘤样病变(CINⅠ~Ⅲ)、15例正常人宫颈组织为观察对象。检测各组hsHPV阳性表达情况,采用免疫组化SP法检测组织内PKR、磷酸化型PKR(p-PKR)、NF-κB p65和磷酸化型NF-κB p65(p-NF-κB p65)在上述分组中的表达。结果231例中hsHPV阳性136例,阴性95例。胞浆中PKR、p-PKR在hsHPV阳性组的表达低于hsHPV阴性组(27.2%和11.0%vs 41.1%和21.1%,χ2分别为4.858、4.371,均P<0.05),在胞浆和胞核中NF-κB p65、p-NF-κB p65在hsHPV阳性组的表达高于hsHPV阴性组(46.3%、25.7%、22.8%和12.5%vs 32.6%、14.7%、11.6%和4.2%,χ2分别为4.345、4.048、4.729、4.650,均P<0.05);在胞浆和胞核中NF-κB p65(+)组PKR的阳性表达率低于NF-κB p65(-)组(25.5%vs 38.0%和20.4%vs 36.3%,χ2分别为3.898、4.396,P<0.05),p-NF-κB p65(+)组在胞浆中PKR的阳性表达率低于p-NF-κB p65(-)组(19.0%vs 36.0%,χ2=4.462,P<0.05)。结论 hsHPV可能抑制PKR的表达及磷酸化而促进NF-κB p65的表达及磷酸化,NF-κB p65的表达及磷酸化对PKR的表达可能有抑制作用;三者间的调节作用可能与宫颈癌的发生发展有关。
目的:探討宮頸病變組織內蛋白激酶R(PKR)、覈因子(NF)-κB p65的錶達及燐痠化的意義,高危型人乳頭狀瘤病毒(hsHPV)對兩者錶達及燐痠化的影響,以及三者的關繫。方法以67例宮頸癌、149例宮頸上皮內瘤樣病變(CINⅠ~Ⅲ)、15例正常人宮頸組織為觀察對象。檢測各組hsHPV暘性錶達情況,採用免疫組化SP法檢測組織內PKR、燐痠化型PKR(p-PKR)、NF-κB p65和燐痠化型NF-κB p65(p-NF-κB p65)在上述分組中的錶達。結果231例中hsHPV暘性136例,陰性95例。胞漿中PKR、p-PKR在hsHPV暘性組的錶達低于hsHPV陰性組(27.2%和11.0%vs 41.1%和21.1%,χ2分彆為4.858、4.371,均P<0.05),在胞漿和胞覈中NF-κB p65、p-NF-κB p65在hsHPV暘性組的錶達高于hsHPV陰性組(46.3%、25.7%、22.8%和12.5%vs 32.6%、14.7%、11.6%和4.2%,χ2分彆為4.345、4.048、4.729、4.650,均P<0.05);在胞漿和胞覈中NF-κB p65(+)組PKR的暘性錶達率低于NF-κB p65(-)組(25.5%vs 38.0%和20.4%vs 36.3%,χ2分彆為3.898、4.396,P<0.05),p-NF-κB p65(+)組在胞漿中PKR的暘性錶達率低于p-NF-κB p65(-)組(19.0%vs 36.0%,χ2=4.462,P<0.05)。結論 hsHPV可能抑製PKR的錶達及燐痠化而促進NF-κB p65的錶達及燐痠化,NF-κB p65的錶達及燐痠化對PKR的錶達可能有抑製作用;三者間的調節作用可能與宮頸癌的髮生髮展有關。

Objective To identify the significance of expression and phosphorylation of protein kinase R(PKR) and nuclear factor NF-κB p65 in cervical lesions, and the effect of high-risk human papilloma virus(hsHPV) on expression and phosphorylation of R(PKR) and NF-κB p65. Methods A total of 67 patients with cervical cancer, 149 patients with cervi-cal intraepithelial neoplasia (CINⅠ-Ⅲ) and 15 normal control were included in this study. The expression levels of PKR, phosphorylated PKR (p-PKR), NF-κB p65 and phosphorylated NF-κB p65 (p-NF-κB p65) were detected by immunohisto-chemical SP method in three groups. Results The positive expression rates of PKR and p-PKR in cytoplasm were signifi-cantly lower in hsHPV positive group than those in hsHPV negative group (27.2% and 11.0% vs 41.1% and 21.1%,χ2 =4.858 and 4.371,P<0.05). The positive expression rates of NF-κB p65 and p-NF-κB p65 in cytoplasm and nucleus were significantly higher in hsHPV positive group than those in hsHPV negative group (46.3%, 25.7%, 22.8% and 12.5% vs 32.6%, 14.7%, 11.6%and 4.2%,χ2=4.345,4.048,4.729 and 4.650 respectively,P<0.05). The positive expression rates of PKR in kytoplasm and karyon were significantly lower in NF-κB p65 (+) group than those in NF-κB p65 (-) group (25.5%vs 38.0%and 20.4%vs 36.3%,χ2=3.898 and 4.396 respectively, P<0.05). The positive expression rate of PKR in kyto-plasm was significantly lower in p-NF-κB p65 (+) group than those in p-NF-κB p65 (-) group (19.0%vs 36.0%,χ2=4.462, P<0.05). Conclusion hsHPV may inhibit the expression and phosphorylation of PKR but promote the expression and phosphorylation of NF-κB p65. The expression and phosphorylation of NF-κB p65 may inhibit the expression of PKR. Regu-lating effects of three may be associated with the generation and progression of cervical cancer.
