Sci Rep:WNT信号在人类胚胎癌细胞中的异常激活和对体外培养的短期和长期影响研究

2019-08-30 AlexYang MedSci原创

人类胚胎癌细胞(EC)包括了恶性非精原细胞瘤性生殖细胞瘤(GCTs)的多能干细胞,并代表了胚胎干细胞(ESCs)的恶性成员。尽管WNT/β-连环蛋白信号在EC细胞中的作用研究较少,其在调控成熟和胚胎干细胞中具有作用。最近,有研究人员调查了WNT信号在代表性的多能和非多能人类EC细胞系中的作用。研究发现,EC细胞系表现出了不同水平的WNT信号,并对异常的WNT激活具有不同的响应。WNT信号的短期激活

人类胚胎癌细胞(EC)包括了恶性非精原细胞瘤性生殖细胞瘤(GCTs)的多能干细胞,并代表了胚胎干细胞(ESCs)的恶性成员。尽管WNT/β-连环蛋白信号在EC细胞中的作用研究较少,其在调控成熟和胚胎干细胞中具有作用。

最近,有研究人员调查了WNT信号在代表性的多能和非多能人类EC细胞系中的作用。研究发现,EC细胞系表现出了不同水平的WNT信号,并对异常的WNT激活具有不同的响应。WNT信号的短期激活能够诱导多能EC细胞(NT2和NCCIT)的区别响应,而非多能细胞(TERA1和2102Ep)却不响应且维持了高水平的OCT4和SSEA4表达水平。另外,WNT信号在NCCIT中的长期激活以及TERA1细胞较小程度上导致OCT4表达和SSEA4到SSEA1表面抗原的转变最终能够导致OCT4+/SSEA4?/SSEA1+的出现。铂治疗表明了OCT4+/SSEA4?/SSEA1+ NCCIT细胞表现出了更强烈的化疗抗性。

最后,研究人员指出,他们的发现阐释了GCT和ES的细胞生物学,并强调了WNT信号在人类EC细胞中的角色。

Brit J Cancer:争光霉素在治疗生殖细胞肿瘤使用中更佳临床指南研究

争光霉素是一种具有细胞毒性的化学治疗药物,是淋巴瘤和生殖细胞瘤治疗方案中的关键组分。在极端案例中,甚至与重度中毒、长期并发症甚至死亡有关。在预防和控制争光霉素毒性方面缺乏相关证据或一致意见。最近,有研究人员调查了63名生殖细胞肿瘤医生,他们来自英国的32个癌症中心,从而来认识和理解他们使用争光霉素的方法。随后指南的开发基于目前的实践、最好的可利用的公开证据以及专家意见。研究人员在以下的领域中观察到

Brit J Cancer:儿科生殖细胞瘤组织亚型DNA甲基化差异分析

异常的DNA甲基化可能是生殖细胞肿瘤(GCT)的病因,因为生殖细胞在发育期间经历了完整的表观遗传重编程。GCTs在组织亚型的全部和启动子甲基化模式中表现出了差异。最近,有研究人员进行了一个表观基因组学研究,并利用GCT组织学对甲基化差异进行研究。研究人员共鉴定了8481个差异甲基化区(DMRs)(FWER?<?0.05)。DMRs中的单个探针的无监督分层聚类结果表明了具有4个聚类,并且与肿瘤

Brit J Cancer:患有生殖细胞肿瘤的儿童和青少年中家族癌症历史研

儿科生殖细胞肿瘤(GCTs)病人的家族癌症历史研究很少,并且到目前为止还没有研究具有足够多的样本数量来特异性的评估GCT家族历史。最近,有研究人员利用一个儿科GCT研究的家族历史数据计算了GCT的标准发生率(SIR)和其他癌症,主要通过利用从SEER计划中的年龄和性别特异性发生率来进行计算。研究发现,分析包括了7998具有儿科GCT渊源的亲属。研究人员观察到了比预期男性和女性渊源者亲属更高的GCT
