摘要
应用TGF-β_1放免分析方法对18例膀胱移行细胞癌进行研究,并选取9例正常膀胱为对照。结果显示:膀胱癌组织中TGF-β_1蛋白表达量显著高于正常膀胱粘膜(P<0.001)。分期T_1组和T_2组TGF-β_1蛋白表达量显著高于Ta组(P<0.05和P≤0.005)。G3组TGF-β_1蛋白表达量显著高于G_1组(P≤0.05)。应用 ̄3H-TdR掺入实验研究表明:TGF-β_1在体外可促进TBC-1系膀胱癌细胞的体外生长。本组结果提示:TGF-β_1蛋白的表达对膀胱癌的生物学行为有重要影响,对评估膀胱癌预后有重要意义。
TGF-β_1 was detected by radioimmunoassay in 18 bladder carcinoma and in 9 normal bladder mucosa as controls. The expression level of TGF-β1 was very significantly higher in bladder carcinoma than that in the normal bladder mucosa(P<0.001)and was significantly higher in T1 and T2 tumors than that in Ta tumors(P<0.05 and P≤0.005).The expression level was also significantly higher in grade 3 than in grade I tumors(P<0.05).With 3H-TdR incorporation assay,exogenous TGF-β1 was noted to stimulate the growth of TBC-1 bladder carcinoma cells in vitro. The results designated that TGF-β1 was relevant to the biological behavier of bladder carcinoma and might serve as an important marker for the evaluation of the prognosis of bladder carcinoma.
