摘要:

目的 探讨血管内皮生长因子(VEGF)和转化生长因子-α(TGF-α)在尖锐湿疣(CA)血管形成中的作用。方法 用RT-PCR 和免疫组化法检测30例CA和15例正常包皮中VEGF、TGF-α和CD34表达。结果 CA中VEGF和TGF-α mRNA表达明显高于正常包皮(P < 0.001);CA中VEGF、TGF-α蛋白阳性表达率分别为90%、86.7%,正常包皮中则为40%、26.7%,二者的差异具有统计学意义(P < 0.01)。CA中微血管密度比正常包皮明显增多(P < 0.01),且CA中VEGF、TGF-α蛋白表达与MVD呈显著正相关(P < 0.01)。结论 CA中VEGF和TGF-α表达上调,可能促进血管生成,参与CA的发生、发展。

Abstract:

Objective To investigate the role of vascular endothelial growth factor (VEGF) and transforming growth factor-α (TGF-α) in the angiogenesis of condyloma acuminatum (CA). Methods Tissue specimens were obtained from the lesions of 30 patients with CA and foreskin of 15 normal human controls. Reverse transcription (RT)-PCR and immunohistochemical method were utilized to measure the protein and mRNA expressions of VEGF and TGF-α in the specimens. Microvessel density(MVD) was determined by staining with anti-CD34 polyclonal antibodies. Results A statistical elevation was observed in the expression of VEGF and TGF-α mRNA as well as MVD in CA specimens compared with the normal control specimens (P < 0.001, 0.001, 0.01). The expressions of VEGF and TGF-α protein were observed in 90% and 86.7% of the CA specimens, and in 40% and 26.7% of the control specimens (both P < 0.01). MVD was positively correlated with the expression of VEGF and TGF-α protein in CA tissues (both P < 0.01). Conclusion The overexpression of VEGF and TGF-α in CA tissue may accelerate angiogenesis in, and participate in the development and progression of, CA.
