Mol Ther Nucleic Acids:剪接体介导的前mRNA反式剪接可以修复CEP290 mRNA的表达异常

2018-09-20 MedSci MedSci原创

美国宾夕法尼亚大学佩雷尔曼医学院眼科学高级视网膜和眼科治疗中心的Dooley SJ近日在Mol Ther Nucleic Acids杂志上发表了一篇重要的文章,他们针对与Leber先天性黑蒙10型(LCA10)和包括Joubert综合征在内的几种综合征疾病,采用剪接体介导的前mRNA反式剪接策略,在体外细胞系中和体内小鼠模型中对CEP290进行编辑,证明有效。

美国宾夕法尼亚大学佩雷尔曼医学院眼科学高级视网膜和眼科治疗中心的Dooley SJ近日在Mol Ther Nucleic Acids杂志上发表了一篇重要的文章,他们针对与Leber先天性黑蒙10型(LCA10)和包括Joubert综合征在内的几种综合征疾病,采用剪接体介导的前mRNA反式剪接策略,在体外细胞系中和体内小鼠模型中对CEP290进行编辑,证明有效。

对于使用重组腺相关病毒(AAV)进行眼部基因治疗,已有研究指出在视网膜疾病的一部分中是安全和有效的,这部分主要是由RPE65缺乏引起的视网膜色素变性和Leber先天性黑蒙(LCA)。同时,目前认为,基因治疗具有独特的优势和安全性,对其他几种疾病也具有疗效。然而,由AAV基因组的包装基因片段大小的能力,限制了对编码序列长度小于5000nt疾病的应用。最普遍的视网膜疾病是由于单基因遗传突变引起,而这不在AAV基因组的包装基因片段大小的范围内。

在这里,针对与Leber先天性黑蒙10型(LCA10)和包括Joubert综合征在内的几种综合征疾病,他们设计了剪接体介导的前mRNA反式剪接策略来回复CEP290的表达。他们使用该策略,在体外细胞系中和体内小鼠模型中对CEP290进行编辑,证明有效。

因此,他们认为,本研究首次研究了CEP290转录本的广泛编辑和体内光感受器中CEP290转录物编辑的可行性,为今后评估治疗效果研究铺平了道路。

Nature:干扰剪接体的功能或可有效杀灭恶性癌细胞

癌症通常就像是油门踏板失控的汽车一样失控驰骋在路上而无法控制,大多数新型的靶向癌症疗法都试图寻找解决癌症“油门踩踏”的问题来解决癌症的发展,但对于很多类型的癌症而言,失控的油门踏板似乎得不到修复,因此科学家们急需一种新型替代疗法,而近日一项刊登于国际杂志Nature上的研究论文中,来自贝勒医学院的科学家通过研究发现了如何抑制一些致死性癌症的新思路。研究者Thomas F. Westbrook教授表

Genes Dev:施一公研究组报道剪接体SF3b复合物结合小分子药物的电镜结构

2018年3月2日,来自施一公研究组的博士后Lorenzo Finci与来自美国的制药公司H3 Biomedicine合作在(Genes & Development)杂志在线发表了题为“The cryo-EM structure of the SF3b spliceosome complex bound to a splicing modulator reveals a pre-mRNA subs

Oncotarget:陆东东课题组发现miR372促进组蛋白去甲基化酶JMJD2A产生的剪接体JMJD2AΔ激活肝癌细胞中癌蛋白Pim1的活性

组蛋白的甲基化修饰调控了染色质的结构,所以在大多数癌症发生过程中显示组蛋白甲基化的异常改变,这与组蛋白甲基化转移酶和去甲基化酶的功能失调密切相关。最近陆东东教授课题组发现组蛋白去甲基化酶JMJD2A通过表观遗传学机制在转录水平上促进了miR372先体的产生,并进一步导致了前体miR372的成熟。进一步研究显示,过量的 miR372能抑制JMJD2A第13外显子右翼和第14外显子左翼特异区域的DNA
