Evaluation of the expression of PEDF in blood serum of prostate cancer patients and its clinical significance
-
摘要: 目的:探讨色素上皮衍生因子(pigmentary epithelium derived factor, PEDF)在前列腺癌患者血清中表达并探讨其临床意义。方法:应用免疫印迹(Western blotting)法检测前列腺癌转移(PCaM)患者、前列腺癌未转移(PCa)患者及良性前列腺增生(BPH)患者血清中PEDF表达情况,并通过统计学方法比较各组PEDF的表达差异。结果:PEDF在BPH组血清样本中高于PCa组(P<0.05),PEDF在PCa组的血清样本中也高于PCaM组(P<0.05)。结论:PEDF与前列腺癌的发生和转移相关,并可能在前列腺癌的进展中起重要作用,借助测定PEDF的表达可以协助前列腺癌的诊断和预后评估。Abstract: Objective: To detect the expression of pigmentary epithelium derived factor (PEDF) in the blood serum of prostate cancer and evaluation its clinical significances. Method: Western blotting method was used to detect PEDF expression in prostate cancer patients with metastasis (PCaM), prostate cancer patients without metastasis (PCa) and benign prostatic hyperplasia patients(BPH). Result: PEDF was more highly expressed in the blood serum of BPH patients than PCa patients (P<0.05). PEDF was also more highly expressed in the blood serum of PCa patients than PCaM patients (P<0.05). Conclusion: PEDF are related to the malignant transformation and metastatis of prostate cancer. To detect the expression of PEDF may make for judging prostate cancer's diagnosis and prognosis.
