摘要

干细胞是生长发育和成人器官稳态的基本驱动力。干细胞的特性--自我更新和分化--对生物合成的要求很高。为了满足这种需求,干细胞和祖细胞进行高转录,即转录组的全面扩增。虽然转录组学的标准归一化方法通常会掩盖高转录,但新方法开始揭示干细胞和祖细胞中全球转录输出的显著范围。我们讨论了探测全局转录变化的技术进展,回顾了有助于确定干细胞高转录特征的最新发现,并提出了这一领域的未来方向。

Hypertranscription: the invisible hand in stem cell biology

Stem cells are the fundamental drivers of growth during development and adult organ homeostasis. The properties that define stem cells – self-renewal and differentiation – are highly biosynthetically demanding. In order to fuel this demand, stem and progenitor cells engage in hypertranscription, a global amplification of the transcriptome. While standard normalization methods in transcriptomics typically mask hypertranscription, new approaches are beginning to reveal a remarkable range in global transcriptional output in stem and progenitor cells. We discuss technological advancements to probe global transcriptional shifts, review recent findings that contribute to defining hallmarks of stem cell hypertranscription, and propose future directions in this field.

期刊介绍: Launched in 1985, Trends in Genetics swiftly established itself as a "must-read" for geneticists, offering concise, accessible articles covering a spectrum of topics from developmental biology to evolution. This reputation endures, making TiG a cherished resource in the genetic research community. While evolving with the field, the journal now embraces new areas like genomics, epigenetics, and computational genetics, alongside its continued coverage of traditional subjects such as transcriptional regulation, population genetics, and chromosome biology. Despite expanding its scope, the core objective of TiG remains steadfast: to furnish researchers and students with high-quality, innovative reviews, commentaries, and discussions, fostering an appreciation for advances in genetic research. Each issue of TiG presents lively and up-to-date Reviews and Opinions, alongside shorter articles like Science & Society and Spotlight pieces. Invited from leading researchers, Reviews objectively chronicle recent developments, Opinions provide a forum for debate and hypothesis, and shorter articles explore the intersection of genetics with science and policy, as well as emerging ideas in the field. All articles undergo rigorous peer-review.
