目的:探讨WWP2、第十号染色体缺失与张力蛋白同源的磷酸酶基因(PTEN)和p70核糖体蛋白S6激酶(p70S6K)蛋白在口腔鳞状细胞癌(OSCC)组织中的差异表达及相关性,以期为其早期防治及生物治疗提供参考。方法应用免疫组化检测12例正常口腔黏膜、20例白斑及54例OSCC组织中WWP2、PTEN和p70S6K蛋白的表达和相关性,并分析其与OSCC组中患者临床病理参数之间的关系。实验数据采用SPSS 16.0统计软件进行Kruskal Wallis test、χ2检验和Fisher′s精确检验,WWP2、PTEN和p70S6K的表达两两进行Spearman等级相关分析。结果 WWP2、PTEN和p70S6K在正常对照组、口腔白斑组及OSCC组中的强表达率分别为33.33%、40%和68.52%;91.67%、85%和48.15%以及25%、45%和75.93%,与其他组相比,以上三种蛋白的表达差异均有统计学意义(P<0.05)。相关性分析表明WWP2与PTEN之间呈负相关(r=-0.236,P=0.028)。PTEN与p70S6K之间呈负相关(r=-0.301,P=0.005)。WWP2与p70S6K之间呈正相关关系(r=0.315,P=0.003)。OSCC组织中WWP2与OSCC的临床分期有相关性,p70S6K与OSCC的分化程度和有无淋巴结转移有相关性(P<0.05)。结论 WWP2、PTEN和p70S6K在口腔黏膜癌变过程的各阶段的组织中差异表达,提示可能在OSCC的发生、发展过程中起重要作用。
目的:探討WWP2、第十號染色體缺失與張力蛋白同源的燐痠酶基因(PTEN)和p70覈糖體蛋白S6激酶(p70S6K)蛋白在口腔鱗狀細胞癌(OSCC)組織中的差異錶達及相關性,以期為其早期防治及生物治療提供參攷。方法應用免疫組化檢測12例正常口腔黏膜、20例白斑及54例OSCC組織中WWP2、PTEN和p70S6K蛋白的錶達和相關性,併分析其與OSCC組中患者臨床病理參數之間的關繫。實驗數據採用SPSS 16.0統計軟件進行Kruskal Wallis test、χ2檢驗和Fisher′s精確檢驗,WWP2、PTEN和p70S6K的錶達兩兩進行Spearman等級相關分析。結果 WWP2、PTEN和p70S6K在正常對照組、口腔白斑組及OSCC組中的彊錶達率分彆為33.33%、40%和68.52%;91.67%、85%和48.15%以及25%、45%和75.93%,與其他組相比,以上三種蛋白的錶達差異均有統計學意義(P<0.05)。相關性分析錶明WWP2與PTEN之間呈負相關(r=-0.236,P=0.028)。PTEN與p70S6K之間呈負相關(r=-0.301,P=0.005)。WWP2與p70S6K之間呈正相關關繫(r=0.315,P=0.003)。OSCC組織中WWP2與OSCC的臨床分期有相關性,p70S6K與OSCC的分化程度和有無淋巴結轉移有相關性(P<0.05)。結論 WWP2、PTEN和p70S6K在口腔黏膜癌變過程的各階段的組織中差異錶達,提示可能在OSCC的髮生、髮展過程中起重要作用。

Objective To investigate the expression and correlation of WW domain?containing protein 2 (WWP2), phophatase and tensinhomolog deleted on chromosome 10 (PTEN) and p70 ribosomal protein S6 kinase(p70S6K)in patients with oral squamous cell carcinoma(OSCC). Methods Immunohistochemical staining method was used to detect the expression of WWP2, PTEN and p70S6K in the biopsy mucosa tissues from 54 cases of OSCC, 20 cases of oral leukoplakia and 12 cases of normal mucosa. SPSS 16.0 software was used for Kruskal Wallis test,Chi?square test,Fisher′s exact test and spearman rank correlation analysis. Results The strong expression rates of WWP2 and p70S6K were 68.52%and 75.93%in OSCC respectively,which were significantly higher than those in other groups(P<0.05),including oral leukoplakia(40%and 45%),and normal mucosa(33.33%and 25%)(P<0.05). The strong expression rate of PTEN in OSCC was 48.15%,which was significantly lower than that in other groups including oral leukoplakia (85%) and normal mucosa (91.67%). In all of these tissues,the negative correlations were found between the expression of WWP2 and PTEN(r=-0.236,P=0.028)as well as PTEN and p70S6K(r=-0.301,P=0.005). In contrast,the positive correlations were found between the expression of WWP2 and p70S6K(r=0.315,P=0.003). The expression of WWP2 was correlated with clinical stage and p70S6K was correlated with pathological grade age and lymph node metastasis in OSCC. Conclusion The expressions of WWP2,PTEN and p70S6K were closely related to the occurrence and development of OSCC,they may play an important role in the pathogenesis of OSCC.
