AI Article Synopsis

  • Chromosomes in the nucleus are made of DNA and proteins, and their genetic information is encoded in linear sequences that require a 3D understanding for accurate interpretation.
  • Recent advancements in technology have revealed how the 3D structure of the genome is organized and its significance for biological functions.
  • Large-scale genomic variations can disrupt this chromatin structure, influencing gene regulation linked to various diseases, which is the focus of recent research on structural variations.

Article Abstract

Chromosomes located in the nucleus form discrete units of genetic material composed of DNA and protein complexes. The genetic information is encoded in linear DNA sequences, but its interpretation requires an understanding of threedimensional (3D) structure of the chromosome, in which distant DNA sequences can be juxtaposed by highly condensed chromatin packing in the space of nucleus to precisely control gene expression. Recent technological innovations in exploring higher-order chromatin structure have uncovered organizational principles of the 3D genome and its various biological implications. Very recently, it has been reported that large-scale genomic variations may disrupt higher-order chromatin organization and as a consequence, greatly contribute to disease-specific gene regulation for a range of human diseases. Here, we review recent developments in studying the effect of structural variation in gene regulation, and the detection and the interpretation of structural variations in the context of 3D chromatin structure.

Altered 3D genome reorganization mediates precocious myeloid differentiation of aged hematopoietic stem cells in inflammation.

Inflammation is a driving force of hematopoietic stem cells (HSCs) aging, causing irreversible exhaustion of functional HSCs. However, the underlying mechanism of HSCs erosion by inflammatory insult remains poorly understood. Here, we find that transient LPS exposure primes aged HSCs to undergo accelerated differentiation at the expense of self-renewal, leading to depletion of HSCs.

Nucleosome is the basic structural unit of the genome. During processes like DNA replication and gene transcription, the conformation of nucleosomes undergoes dynamic changes, including DNA unwrapping and rewrapping, as well as histone disassembly and assembly. However, the wrapping characteristics of nucleosomes across the entire genome, including region-specificity and their correlation with higher-order chromatin organization, remains to be studied.

Previous studies have demonstrated the dynamic changes in chromatin structure during retinal development correlate with changes in gene expression. However, those studies lack cellular resolution. Here, we integrate single-cell RNA sequencing (scRNA-seq) and single-cell assay for transposase-accessible chromatin sequencing (scATAC-seq) with bulk data to identify cell-type-specific changes in chromatin structure during human and murine development.

Background: African Americans (AA) are disproportionally burdened by Alzheimer's disease (AD), but there is a scarcity of research focusing on understanding the neuroimmune component of AD pathogenesis in this population. It is generally accepted that microglia would be an ideal therapeutic target for AD and that genetic, lifestyle, societal and environmental factors and stressors have the potential to shape microglia phenotypes and their contribution to neurodegenerative processes. The overarching goal of the current study is to establish the population structure of microglia in older AAs and to investigate the relationship of the different microglia subsets with histopathological hallmarks of brain aging and AD in AAs.
