To investigate the expression of heat shock protein-70 (HSP-70) in transitional cell bladder cancer and correlate it with normal and inflammatory bladder tissue samples.
We used a three-step avidin-biotin method to examine the localization of a rabbit anti-HSP-70 polyclonal antibody in normal (n = 10), inflammatory (n = 10), and malignant (n = 67) bladder tissue samples.
Fifty-eight percent of the bladder cancer samples and only 10% and 20% of the normal and inflammatory bladder tissue samples, respectively, expressed HSP-70. Localization of the antibody correlated with the grade (P <0.001), stage (P <0.001), and survival (P <0.05) of the patients with malignancy.
HSP-70 is frequently overexpressed by bladder cancer cells and could be used as biochemical marker in patients with bladder cancer.
研究热休克蛋白-70(HSP-70)在移行细胞膀胱癌中的表达,并将其与正常膀胱组织和炎性膀胱组织样本进行关联。
我们采用三步抗生物素蛋白-生物素方法,检测兔抗HSP-70多克隆抗体在正常膀胱组织(n = 10)、炎性膀胱组织(n = 10)和恶性膀胱组织(n = 67)样本中的定位。
分别有58%的膀胱癌样本、仅10%的正常膀胱组织样本和20%的炎性膀胱组织样本表达HSP-70。抗体定位与恶性肿瘤患者的分级(P <0.001)、分期(P <0.001)和生存率(P <0.05)相关。
HSP-70在膀胱癌细胞中经常过度表达,可作为膀胱癌患者的生化标志物。
