Nat Commun:MUC1-C能够调节谱系可塑性从而驱动神经内分泌前列腺癌的进展

2020-01-29 AlexYang MedSci原创

神经内分泌前列腺癌(NEPC)是一种恶性肿瘤,并且目前没有有效的靶向治疗方法。致癌MUC1-C蛋白在去是抵抗性前列腺癌(CRPC)和NEPC中过表达,而起特异的作用仍旧未知。最近,有研究人员阐释了MUC1-C在雄激素依赖的PC细胞中表达的上调能够抑制雄激素受体(AR)轴信号,并诱导神经BRN2转录因子。MUC1-C能够激活与MYCN、EZH2和与NEPC进展有关的NE分化标记(ASCL1、AURK

神经内分泌前列腺癌(NEPC)是一种恶性肿瘤,并且目前没有有效的靶向治疗方法。致癌MUC1-C蛋白在去势抵抗性前列腺癌(CRPC)和NEPC中过表达,而其特异的作用仍旧未知。

最近,有研究人员阐释了MUC1-C在雄激素依赖的PC细胞中表达的上调能够抑制雄激素受体(AR)轴信号,并诱导神经BRN2转录因子。MUC1-C能够激活与MYCN、EZH2和与NEPC进展有关的NE分化标记(ASCL1、AURKA和SYP)相关的MYC-BRN2途径。更多的是,MUC1-C能够抑制p53途径,诱导Yamanaka多能因子(OCT4、SOX2、KLF4和MYC)并驱使干细胞化。靶向MUC1-C能够减少PC自我更新能力和致瘤性,表明了CRPC和NEPC的一种潜在的治疗方法。在PC组织中,MUC1的表达与AR信号的抑制相关,并能够增加BRN2的表达和NEPC评分。

最后,研究人员指出,他们的结果强调了MUC1-C是驱使发展为NEPC谱系可塑性的一个主控因子。

Sci Rep:循环miR-141和miR-375与转移去势抵抗性前列腺癌的治疗结果相关

转移去势抵抗性前列腺癌(mCPRC)与高的死亡率相关,而疾病活性的控制到目前为止仍旧是一个主要的临床挑战。小RNA(miRs)在前列腺癌的诊断和预后中的作用已经有广泛的研究。最近,有研究人员在mCRPC患者中调查了循环miRs与治疗结果的关系。研究人员调查了84名mCRPC患者血浆样本中5个miRs(miR-93-5p、- 125b1 -5p、-141-3p、-221-3p和miR-375-3p)

Prostate Cancer P D:经会阴和经直肠MRI-US融合活检在前列腺癌检测中的准确性研究

核磁共振成像(MRI)和超声(US)融合前列腺活检可以通过经会阴(TR-融合)或者经直肠(TP-融合)的方法来进行。目前来讲,前瞻性的比较性证据仍旧有限。最近,有研究人员比较了指数病变内TR和TP融合在临床显著性前列腺癌(csPCa)中的检出率情况。研究是一个前瞻性的、非虐性和人之间的试验,共有77名患者完成了整个过程。平均年龄为68.2岁(IQR:64.2-72.2),平均PSA为8.9ng/m

盘点:前列腺癌治疗方法进展

【1】Sci Rep:盆腔淋巴结清扫术对前列腺患者益处分析 盆腔淋巴结清扫术(PLND)是前列腺癌淋巴结分期的金标准,并且需要在淋巴结浸润(LNI)可能性>5%的患者中进行。然而,PLND的治疗作用和作用程度仍旧存在争议。最近,有研究人员回顾性的分析了2010年到2015年经历和没有经历PLND的20688名进行了根治性前列腺切除(RP)的患者。所有的患者LNI>

Prostate Cancer P D:高风险前列腺癌中GLUT1的表达分析

肿瘤18F-FDG摄取在高风险和转移前列腺癌(PCa)中具有预后价值。最近,有研究人员调查了PCa中18F-FDG摄取对PET/CT成像潜在的葡萄糖代谢机制。研究是一个回顾性的分析,包括了94名诊断为格林森总和≥8的前列腺癌患者,他们均在根治性前列腺切除术前经历了18F-FDG-PET/CT成像。研究的平均跟踪调查时间为4.5年,56%的患者(n=53)具有生化复发(BCR),7%(n=7)的患者

前列腺癌治疗的ORIC-101联合XTANDI的Ib期临床试验正式开始

临床前研究表明,新型糖皮质激素受体(GR)拮抗剂ORIC-101可能会抑制转移性前列腺癌患者对XTANDI(enzalutamide)的潜在耐药。

Sci Rep:先进的放疗技术和剂量增强对根治性前列腺切除术后挽救治疗毒性的影响

剂量递增放疗与强度调节放疗(IMRT)和成像指导的放疗(IGRT)的安全性和疗效在根治性前列腺切除术后挽救治疗(SRT)中仍旧不清楚。最近,有研究人员调查了这些先进的放疗技术和剂量增强对SRT毒性的影响。他们的多机构回顾性研究包括了421名患者,他们经历了SRT手术,平均剂量为66Gy。IMRT和IGRT分别用于225名患者(53%)和321名患者(T76%)。在平均跟踪调查的50个月中,晚期2级
