General description

这种核苷酸结构名为2,2,7-三甲基鸟苷(m3G),含有小核糖核蛋白颗粒的帽结构,即U snRNP,是mRNA处理的重要组成部分。每个snRNP粒子包含一个(U1、U2和U5)或两个(U4/U6) snRNA分子,一组共有的8个核心蛋白质(B、B9、D1、D2、D3、E、F和G,也表示为Sm蛋白质),这些蛋白质分别结合至含有2,2,7-三甲基鸟苷(m3G)帽的snRNAs U1、U2、U4和U5,以及几个与单个U snRNP专门相关的蛋白质。 除了不离开细胞核的U6 snRNP外,这些U snRNP的合成需要snRNA通过核膜的双向运输。snRNA U1、U2、U4和U5在具有7-单甲基鸟苷(m7G)帽结构的细胞核中合成,而Sm蛋白储存在细胞质中,在没有结合U snRNA的情况下不会迁移到细胞核中。相反,新转录的U snrna被暂时输出到Sm蛋白结合snRNA的Sm位点的细胞质中,形成被称为Sm核的核蛋白复合体。所有Sm蛋白的稳定结合是m7G-cap至m3G-cap结构的高甲基化的必要条件。经过这一事件和snRNA的处理后,成熟的snRNP颗粒以受体和能量依赖方式被运送回细胞核,形成完整颗粒。 单克隆H-20既能识别带有snRNP的m3G帽,也能识别带有m7G帽的结构,应用非常广泛,不仅可用于研究不同生物U snRNP的分子生物学和免疫学,也可用于m7G帽转录物的表征和分离。

"Apoptosis & Autophagy in Cancer: Cell Survival by Eluding Cell Death The ability of tumor cells to elude programmed cell death, also known as apoptosis, is a hallmark of most types of cancer. Similary, autophagy is a highly regulated, homeostatic degradative process where cells destroy their own components via the lysosomal machinery and recycle them for prolonged cell survival. Via extensive crosstalk with pro-apoptotic signaling pathways, autophagy can also contribute to cell death and greatly influence general cell health. Elucidating the correlation between autophagy and apoptotic cell death has become the focus of a great deal of research, particularly in tumor biology. On one hand, autophagy may induce cell death by degrading essential components; on the other hand, it may facilitate survival of cancer cells under unfavorable metabolic conditions."
