Abstract
Chromosome structure regulates DNA-templated processes such as transcription of genes. Dynamic changes to chromosome structure occur during development and in disease contexts. The cohesin complex is a molecular motor that regulates chromosome structure by generating DNA loops that bring two distal genomic sites into close spatial proximity. There are many open questions regarding the formation and dissolution of DNA loops, as well as the role(s) of DNA loops in regulating transcription of the interphase genome. This review focuses on recent discoveries that provide molecular insights into the role of cohesin and chromosome structure in gene transcription during development and disease.
染色体结构调节基因转录等由 DNA 触发的过程。染色体结构在发育过程中和疾病情况下会发生动态变化。粘合素复合物是一种分子马达，它通过产生DNA环来调节染色体结构，从而使两个远端基因组位点在空间上接近。关于 DNA 环的形成和解体，以及 DNA 环在调节间期基因组转录中的作用，还有许多未决问题。本综述将重点介绍最近的发现，这些发现从分子角度揭示了凝聚素和染色体结构在发育和疾病过程中基因转录的作用。
期刊介绍：
Current Opinion in Genetics and Development aims to stimulate scientifically grounded, interdisciplinary, multi-scale debate and exchange of ideas. It contains polished, concise and timely reviews and opinions, with particular emphasis on those articles published in the past two years. In addition to describing recent trends, the authors are encouraged to give their subjective opinion of the topics discussed.
In Current Opinion in Genetics and Development we help the reader by providing in a systematic manner:
1. The views of experts on current advances in their field in a clear and readable form.
2. Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications.[...]
The subject of Genetics and Development is divided into six themed sections, each of which is reviewed once a year:
• Cancer Genomics
• Genome Architecture and Expression
• Molecular and genetic basis of disease
• Developmental mechanisms, patterning and evolution
• Cell reprogramming, regeneration and repair
• Genetics of Human Origin / Evolutionary genetics (alternate years)
