In this study we detected the expression of pim-1 mRNA in normal prostate, benign prostatic hyperplasia （BPH）, and prostate cancer （PCa） and explored its diagnostic value for PCa. Methods The prostate tissues were collected from 23 patients with PCa, 37 patients with BPH, and 3 healthy volunteers. Pim-1 mRNA expression levels in these samples were determined by the quantitative real-time PCR （QRT-PCR）. The differences of expression were calculated based on a standard curve. Results The ratio of pim-1 mRNA to β-actin in the normal prostate, BPH, and PCa were 1.05±0.04, 2.57±0.74 and 4.45±0.63, respectively. The differences among PCa, BPH and NT were significant （P〈0.05, respectively）. Conclusion Detecting pim-1 mRNA expression by QRT-PCR provides a reliable metric for the diagnosis of PCa.展开更多
目的:探讨人卵巢上皮性癌组织中Pim-1和C-myc的表达及其临床意义。方法:采用RT-PCR半定量方法和免疫组织化学法检测40例卵巢上皮性癌组织、20例卵巢上皮性良性肿瘤组织和10例正常卵巢组织中Pim-1和C-myc mRNA及蛋白的表达情况。结果:卵...目的:探讨人卵巢上皮性癌组织中Pim-1和C-myc的表达及其临床意义。方法:采用RT-PCR半定量方法和免疫组织化学法检测40例卵巢上皮性癌组织、20例卵巢上皮性良性肿瘤组织和10例正常卵巢组织中Pim-1和C-myc mRNA及蛋白的表达情况。结果:卵巢上皮性癌组织中Pim-1和C-myc mRNA与蛋白的表达水平明显高于卵巢上皮性良性肿瘤组织及正常卵巢组织(P<0.05);Pim-1蛋白在卵巢上皮性癌组织中的表达与其组织学类型无关(P>0.05),与国际妇产科联盟(Federation International of Gynecology and Obstetrics,FIGO)分期和淋巴结转移有关(P<0.05);C-myc蛋白在卵巢上皮性癌组织中的表达与其组织学类型、FIGO分期和淋巴结转移均无关(P>0.05)。结论:原癌基因Pim-1和C-myc的mRNA及蛋白在卵巢上皮性癌组织中过度表达,可能与卵巢上皮性癌的发生、发展有关。展开更多
