Sci Rep:前列腺癌细胞中Skp2的高表达与间叶细胞表型和致瘤潜能的增加相关

2019-04-19 AlexYang MedSci原创

Skp2是SCFSkp2E3泛素连接酶的关键组分,并且在各种类型的癌症中均过表达,包括了前列腺癌(PCa)。上皮间质转化(EMT)与PCa的恶化相关。最近,有研究人员基于PCa中间叶细胞表型的获得能够导致癌症干细胞(CSC)表型这一现象,调查了Skp2在PCa患者的临床样本中的表达和定位情况,并调查了Skp2与EMT状态的相关性和Skp2在前列腺CSC中的作用。研究发现,与良性增生患者相比,Skp

Skp2是SCFSkp2E3泛素连接酶的关键组分,并且在各种类型的癌症中均过表达,包括了前列腺癌(PCa)。上皮间质转化(EMT)与PCa的恶化相关。

最近,有研究人员基于PCa中间叶细胞表型的获得能够导致癌症干细胞(CSC)表型这一现象,调查了Skp2在PCa患者的临床样本中的表达和定位情况,并调查了Skp2与EMT状态的相关性和Skp2在前列腺CSC中的作用。研究发现,与良性增生患者相比,Skp2的细胞核表达在PCa患者中增加,并且在PCa患者中与高格林森等级相关。研究人员在间叶细胞表型和类CSC表型的PCa细胞系中观察到了Skp2表达的增加。与之相反,类CSC表型在Skp2表达沉默的细胞中减弱。更多的是,研究人员观察到了Skp2下调能够导致CD44+CD24-类癌症干细胞亚群减少。另外,研究人员指出,PCa患者中CD24和CD44的高表达与良好的无复发生存相关。

最后,研究人员指出,他们的研究阐释了PCa中Skp2调控的类CSC表型与致瘤功能。

ACS Nano:新型诊断成像技术助化学疗法杀灭前列腺癌细胞

通过对人类和小鼠前列腺癌细胞进行研究,来自约翰霍普金斯大学的癌症成像专家开发出了一种新型的方法来用于发现和消灭恶性的肿瘤细胞。这种方法名为治疗诊断学成像,其可以直接打靶和追踪潜在的药物疗法来专门消灭癌细胞。这种新方法依赖于结合在化疗药物的钝化形式上,来最终吸附于肿瘤细胞表面的特殊蛋白上,最终检测药物对肿瘤的作用,这种高度的药物-蛋白复合物(或者nanoplex)的结合允许其进入癌细胞的内部来发挥杀

Prostate:PSCA可以通过上调c-Myc促进前列腺癌细胞增殖和细胞周期进程

前列腺癌干细胞抗体(PSCA)是一种糖基磷脂酰肌醇(GPI)锚定蛋白。越来越多的证据表明了PSCA在致瘤过程中具有重要角色。然而,它在前列腺癌(PCa)中的功能和潜在的分子机制仍旧还没有完全的阐释。最近,有研究人员就探究了PSCA对PCa细胞周期的影响和潜在的机制。研究人员在PCa组织和细胞系中利用免疫组化技术、定量反转录-PCR(qRT-PCR)和蛋白免疫印迹技术定量了PSCA的表达。研究人员利

Cancer Sci:β-抑制蛋白1对FOXO3a的抑制作用能够促使前列腺癌细胞的生长

最近,有研究表明β-抑制蛋白1可以通过促进细胞增殖和上皮到间质之间的转化(EMT)可作为前列腺癌的促使因子,但是潜在的机制仍旧不清楚。最近,有研究人员阐释了体内和体外中,β-抑制蛋白1能够促进细胞生长,具体是通过抑制FOXO3a在前列腺癌细胞中的转录活性和表达来实现。详细地,研究人员发现β-抑制蛋白1能够促进前列腺癌的细胞和肿瘤生长,并且在前列腺癌细胞系中和组织中,β-抑制蛋白1的表达表现出了与F
