Trends Cancer:阻断细胞凋亡的反应可使癌症女性接受放化疗后仍保持生育能力

通过靶向卵母细胞中的DNA损伤反应,可使得处于生殖年龄的癌症女性患者在放疗和化疗期间仍能保持他们的生殖能力,该治疗方法已在动物模型中取得成功。

杰克逊实验室助理教授Ewelina bolcun博士以及来自德克萨斯大学MD安德森癌症中心的助理教授Terri L. Woodward博士在Trends in Cancer中将此方法描述为,“延长癌症后的生殖期:生育保护疗法的需要”。

“好消息是,更多的年轻女性可在患癌后幸存,” Bolcun-Filas说道,“这表明有更好更有效的治疗方法的出现。但是,许多癌症治疗增加了卵巢功能不全(POI)和不孕的发生危险。”虽然辅助生殖技术可以解决不孕的问题,但是却不能保留卵巢的正常功能,而卵巢的正常功能在女性的健康中发挥着重要的作用,而不仅仅是孕育后代。

许多癌症治疗不仅会导致癌细胞的DNA损伤,还会损伤正常组织的DNA,如卵巢。这种损伤的自然反应是通过细胞凋亡或程序性死亡来清除卵母细胞。Bolcun-Filas近期的小鼠实验研究以及其他研究人员的研究发现表明,靶向参与细胞凋亡的蛋白质可保护卵母细胞,并可预防接受放疗的女性不孕的发生。

研究人员回顾了该研究成果展示了癌症疗法如何诱导卵母细胞中的细胞凋亡,以及这项研究发现如何应用于设计更好的生育保护治疗措施。

最后,研究人员说道,“更好地了解卵母细胞对辐射和抗癌药物的反应将为研发预防卵巢衰竭的专用疗法揭开新的靶向目标。”

Biol Reprod:母亲糖尿病能削弱卵母细胞印迹基因的甲基化

科研人员首次证明了没有得到良好控制的母亲糖尿病能对母亲印迹基因Peg3的甲基化产生不良影响,这对后代发育受到损害有贡献。 此前的研究已经表明,糖尿病母亲的后代表现出了更高的畸形和死胎的发生率,即便是把一个单细胞胚胎从糖尿病母亲移植到非糖尿病母亲体内的时候也是如此。糖尿病母亲的卵母细胞倾向于表现出葡萄糖代谢减少,卵丘细胞和卵母细胞之间的通信被削弱,线粒体失灵,以及排卵率下降,所有这些都可以追溯到胚

Science:男女通用避孕药有戏!发现黄体酮激活的人精子受体

Science:细胞重编程的关键组蛋白伴侣分子

近日,刊登在国际杂志Science上的一篇研究论文中,来自密歇根州立大学的研究人员通过研究发现,名为ASF1A的基因在干细胞发育过程中发挥着重要作用;干细胞可以发育分化成为机体不同类型的细胞组织从而挽救人类的生命。 实际上ASF1A基因并不是本文的研究人员所发现的,该基因主要负责细胞的重编程,细胞的重编程即转变细胞的类型,这对于干细胞的分化至关重要。这项研究中,研究人员分析了卵母细胞中500
