Sci Rep:在前列腺癌患者中,基因表达的失调能够预测肿瘤恶化

2018-11-15 AlexYang MedSci原创

前列腺癌(PCa)患者的健康差异潜在的分子机制还没有很好的阐释。最近,有研究人员应用了生物信息学手段鉴定和确认了具有肿瘤恶化的非裔美国人(AA)中,与白种美国人(CA)相比表达失调的基因。研究人员总共分析了619名PCa患者的基因芯片数据,其中412名为AA,207名为CA。研究人员通过RT-PCR、蛋白免疫印迹、免疫细胞化学(ICC)和免疫组织化学分析在肿瘤组织和细胞系中确定了这些基因。研究人员

前列腺癌(PCa)患者的健康差异潜在的分子机制还没有很好的阐释。最近,有研究人员应用了生物信息学手段鉴定和确认了具有肿瘤恶化的非裔美国人(AA)中,与白种美国人(CA)相比表达失调的基因。

研究人员总共分析了619名PCa患者的基因芯片数据,其中412名为AA,207名为CA。研究人员通过RT-PCR、蛋白免疫印迹、免疫细胞化学(ICC)和免疫组织化学分析在肿瘤组织和细胞系中确定了这些基因。研究人员在AA男性中总共鉴定了362个与调控肿瘤恶化相关的差异表达的基因。在PCa组织和细胞中,与正常细胞相比,NKX3.1, APPL2, TPD52, LTC4S, ALDH1A3和AMD1转录本显著上调(p<0.05)。另外,与CA男性相比,IHC确定了TPD52(p=0.0098)和LTC4S (p<0.0005)在AA男性中表达的显著上调。在PCa细胞中,ICC和蛋白免疫印迹分析同样也证实了上述分析结果。

最后,研究人员指出,这些结果表明了PCa中转录本表达的失调可能促使了PCa结果差异的产生,并且为开发治疗恶性肿瘤的新药物提供了新的认识。同时,研究人员还指出,更多的研究是需要的,从而来调查这些表达失调基因的临床意义。

Prostate Cancer P D:DNMT3B单核苷酸多态性和DNMT3B Mrna表达与前列腺癌死亡率相关

DNA甲基化转移酶3B(DNMT3B)的生殖系变异可能影响DNMT3B的酶活性,反过来,也可能通过改变DNA甲基化来影响癌症的恶化。最近,有研究人员在2个意大利前列腺癌群体(n=157和182)和2个美国前列腺癌群体(n=214和298)中进行了案例-对照研究。研究人员在NTAT群体中利用线性回归评估了选择的3个DNMT3B变异与全部DNA甲基化之间的相关性;在所有群体中利用Cox比例风险回归评估

前列腺癌(PCa)肿瘤包含有ETS家族基因和雄激素响应TMPRSS2基因的易位情况(ETS+肿瘤),这也为大约70%的患者中检测PCa提供了强有力的生物标记。ETS+PCa能够表达出高水平的性激素受体(AR),而缺乏ETS融合(ETS-)的PCa肿瘤同样也表达AR,并且还表现出雄激素调控的生长。最近,有研究人员评估了ETS+和ETS-PCa肿瘤中,AR调控的转录组差异。研究发现,基于AR依赖的基因
