摘要:

目的评估LNCaP细胞中雄激素依赖性和雄激素非依赖性蛋白质组学特征,探讨前列腺癌的雄激素非依赖性生长的分子机制。方法雄激素敏感性LNCaP细胞在常规细胞培养基中持续培养。在雄激素递减环境中培养雄激素敏感的LNCaP细胞,且培养出了稳定传代的细胞,命名为LNCaPs细胞。检测两种不同的LNCaP细胞生长特性和对雄激素的反应,观察饥饿细胞的形态学变化。通过双相凝胶电泳(2DE)和基质辅助激光解析电离/飞行时间质谱测量法(MALDITOF MS)分析前列腺癌 LNCaP细胞的蛋白表达。结果在2DE LNCaP蛋白谱中,成功鉴定出了222种蛋白质。与LNCaP细胞相比,在LNCaPs细胞中发现150种蛋白表达差异有统计学意义,成功鉴定出75种蛋白质。LNCaP 蛋白谱中发现在LNCaPs 细胞中有26种蛋白表达上调或下调,且其蛋白受生长激素抑素(sms)以及其类似物(smsdx)的影响。鉴定出的蛋白参与多种生理过程,包括应激反应、细胞内信号转导和凋亡。在LNCaPs 细胞中,150种蛋白中7种蛋白表达上调,其余表达下调。蛋白质表达的定性分析显示,LNCaP细胞中有6种蛋白在LNCaPs细胞中无表达。与LNCaP细胞相比,LNCaPs细胞系中未发现新蛋白。结论LNCaP细胞中雄激素依赖性和雄激素非依赖性蛋弊质表达不同,且受sms及smsdx影响,可提供潜在的诊断和预后判断的标记物及药物治疗靶点并充实前列腺癌蛋白库,对基础和临床研究有重要意义。

Abstract:

To evaluate androgendependent and androgenindependent proteome in LNCaP cells and to investigate the molecular mechanism of androgenindependent growth of prostate cancer. MethodsAndrogensensitive LNCaP parental cells were continuously maintained in a regular cellculture medium. We established a new stable prostate cancer cell (LNCaPs) by culturing androgensensitive LNCaP cells in an androgenreduced condition, and examined the growth properties and androgen responsive of these different LNCaP cells, also observed the morphological changes of those starved cells. We made a comprehensive study of protein expression of the parental androgensensitive prostate cancer LNCaP cells by means of agarose twodimensional gel electrophoresis (2DE) followed by a MALDITOF mass spectrometric analysis. ResultsDuring the creation of  2DE protein maps, 222 proteins in total were successfully identified. Based on strict statistical criteria, 150 spots were found to be significantly differentially expressed in an upand downregulation manner in LNCaPs compared with the parental LNCaP cells, of which we had successfully matched 75 correspondingly. Referring to the LNCaP protein map, it was  found that 26 proteins were upand downregulated in LNCaPs cells, and these proteins were affected by somatostatin treatment. Identified proteins were involved in diverse processes including the stress response, intracellular signaling and apoptosis. Only 7 protein spots in 150 were upregulated in LNCaPs cells. The rest of them were all downregulated. After a qualitative change analysis of protein expression, 6 new proteins were found from 75 presented in the parental LNCaP cells. No new proteins in LNCaPs cell lines  were found compared with parental LNCaP cells. ConclusionIn LNCaP cells, androgendependent and androgenindependent protein differently express and are affected by sms and smsdx. They may provide potential biomarkers for diagnosis, prognosis and therapy targets, while they contribute for prostate cancer protein databases.
