摘要
目的:探讨STEAP基因的功能。方法:应用RT-PCR、免疫印迹的方法,检测STEAP mRNA和蛋白在国人正常前列腺、前列腺癌组织中的表达水平。应用钼酸还原法检测正常前列腺内腺、外腺及前列腺癌组织H2O2水平,同时应用黄嘌呤氧化法测定3种组织中SOD水平,分析其与STEAP表达的相关性。结果:国人前列腺癌STEAP mRNA和蛋白高表达;前列腺癌组织中H2O2水平及总SOD水平明显高于正常前列腺。结论:STEAP的功能之一可能是诱导内源性H2O2水平增高,促进细胞快速生长。
AIM: To observe the STEAP expression and its function in human prostate tissues. METHODS: The expressions of STEAP mRNA and protein were detected by RT - PCR and Westem blotting. H2O2 and SOD levels were detected by molybdic acid reduction and xanthine oxidation methods respectively. RESULTS: STEAP mRNA and protein were highly expressed in prostate cancer tissues. H2O2 and SOD levels in prostate cancer were obviously higher than those in normal prostate tissue. CONCLUSION: The function of STEAP gene is possibly to induce intracellular H2O2 and promote cell growth.
