摘要:

目的 研究加热对人舌癌Tca8113细胞尿激酶型纤溶酶原激活物(UPA)表达的影响。方法 采用免疫组织化学染色和流式细胞术检测Tca8113细胞在不同加热温度下(37℃、40℃、43℃、45℃)UPA表达情况。结果 与37℃组相比,40℃、43℃组加热后Tca8113细胞UPA表达明显下降(P<0·05),而45℃组UPA表达下降,但无统计学意义(P>0·05)。结论 口腔鳞癌局部热疗不会促进侵袭、转移,还会对肿瘤的侵袭、转移有抑制作用。

Abstract:

Objective The aim of this studywas to observe the expression of urokinase-type plasminogen activator (UPA) in human tongue squamous cell carcinoma cell line (Tca8113) after heat shockwith different dosage.Methods The expression of UPA protein ofTca8113 after different heating temperatures(37℃、40℃、43℃and 45℃) treatmentwas examined by immuno- histochemical technique (IH) and flow cytometry (FCM).Results Compared with 37℃group, the UPA protein expression in 40℃and 43℃groups decreased significantly (P<0·05); however, the UPA protein expression in 45℃group decreased but no statistical difference was found.Conclusion Hyperthermia could inhibit invasion and metastasis of oral squamous cell carcino- ma and could be considered as a safe method in curing the tumor.
