Abstract

This week's issues of Science, Science's STKE, and SAGE KE (www.sciencemag.org/sciext/rna/) focus on the increasing complexity that RNA brings to cellular biology. STKE resources include Reviews, Perspectives, and Teaching Resources. STKE specifically looks at the roles for small RNAs in regulation of gene expression and how mRNAs can be selectively activated from cytoplasmic macromolecular structures, RNA granules, to contribute to such processes as synaptic plasticity.

摘要

本周的《科学》《科学信号》及《科学与转化医学知识环境》（www.sciencemag.org/sciext/rna/）聚焦于RNA给细胞生物学带来的日益增加的复杂性。《科学信号》的资源包括综述、观点和教学资源。《科学信号》特别关注小RNA在基因表达调控中的作用，以及信使核糖核酸（mRNA）如何从细胞质大分子结构——RNA颗粒中被选择性激活，从而促进诸如突触可塑性等过程。
