摘要: 目的 探讨磷酸化细胞信号传导与转录活化因子3(p-Stat3)和磷酸化Akt(p-Akt)及磷酸化细胞外信号调节激酶(p-ERK1/2)在表皮良恶性肿瘤中的表达.方法 采用免疫组化的方法检测脂溢性角化病,光线性角化病,鲍恩样丘疹病,基底细胞上皮瘤,鲍恩病,鳞状细胞癌中p-Stat3,p-Akt及p-ERK1/2的表达.结果 p-Stat3,p-Akt及p-ERK1/2阳性表达率在表皮恶性肿瘤中明显高于良性肿瘤(P均<0.05).p-Stat3和p-Akt的阳性表达率在表皮恶性肿瘤中从高到低依次为鳞状细胞癌>鲍恩病>基底细胞上皮瘤,而p-ERK1/2的阳性表达率无差异(P>0.05).在表皮恶性肿瘤中,p-Stat3和p-Akt的阳性表达呈显著正相关(P<0.05).而p-ERK1/2的阳性表达与p-Star3、p-Akt的阳性表达之间无相关性(P>0.05).结论 p-Stat3,p-AKT和p-ERK1/2参与表皮恶性肿瘤的发病.

Abstract: Objective To investigate the expression ofp-Stat3,p-Akt and p-ERK1/2 in benign and malignant epidermal tumors.Methods Immunohistochemistry SP method was used to detect the expression of p-Stat3,p-Akt and p-ERK1/2 in specimens from 20 cases of seborrheic keratosis(SK),20 cases of actinic keratosis(AK),20 cases of bowenoid papulosis(BP),20 cases of basal cell carcinoma(BCC),20 cases of Bowen's disease(BD)and 50 cases of squamous cell carcinoma(SCC).Results The expression rates of p-Stat3,p-Akt and p-ERK1/2 were significantly higher in malignant epidermal tumors than those in benign epidermal tumors(all P<0.05).In malignant tumors,the expression rates of p-Stat3 and p-Akt were in decreasing order in SCC,BD and BCC,while the expression of p-ERK1/2 was of no significant difference(P>0.05).There was a positive correlation between the expression of p-Stat3 and p-Akt(P<0.05),but the expression of p-ERK1/2 did not correlate with that of p-Stat3 and p-Akt(both P>0.05). Conclusion p-Stat3,p-Akt and p-ERK1/2 may take part in the pathogenesis of malignant epidermal tumors.
