摘要:

目的 探讨垂体瘤转化基因(PTTG)和碱性成纤维细胞生长因子(bFGF)在皮肤鳞状细胞癌(皮肤鳞癌)中的作用及其临床病理意义。方法 采用原位杂交及免疫组化的方法检测42例皮肤鳞癌组织及42例正常皮肤组织中PTTG、bFGF蛋白及mRNA的表达。结果 皮肤鳞癌组织中PTTG和bFGF蛋白(27/42、64.3%和31/42、73.8%)及mRNA(25/42、59.5%和29/42、75.0%)阳性表达率均显著高于正常皮肤组织蛋白(5/42、11.9%和9/42、21.4%)及mRNA表达(3/42、7.1%和7/42、16.7%),组间比较差异均有统计学意义(P < 0.05);PTTG蛋白和mRNA与皮肤鳞癌的组织学分级密切相关(P < 0.05);PTTG与bFGF的蛋白及mRNA表达均呈正相关(P < 0.05)。结论 PTTG和bFGF蛋白及mRNA表达率升高可能与皮肤鳞癌的发病相关。

Abstract:

Objective To investigate the role and clinical pathological significance of PTTG and bFGF in cutaneous squamous cell carcinoma (CSCC). Methods Tissue specimens were collected from the lesions of 42 patients with CSCC and normal skin of 42 normal human controls. The protein and mRNA expressions of PTTG and bFGF were detected by immunohistochemistry and in situ hybridization in these specimens respectively. Results A significant increase was observed in the positive expression rates of PTTG and bFGF proteins [64.3% (27/42) vs. 11.9% (5/42),73.8% (31/42) vs. 21.4% (9/42), both P < 0.05] and mRNA [59.5% (25/42) vs. 7.1% (3/42), 75.0% (29/42) vs. 16.7% (7/42), both P < 0.05] in the CSCC tissue specimens than in the control specimens. The protein and mRNA expressions of PTTG were positively correlated with those of bFGF (both P < 0.05),and closely correlated with histological grade of CSCC(both P < 0.05). Conclusion The high expression of PTTG and bFGF may be associated with the initiation of CSCC.
