About this Research Topic

Background

Genetic inheritance relies on the proper organization of chromosomes and the genome. Structural and numerical chromosomal aberrations are associated with acquired and constitutional human disorders as changes within the genomic architecture that can impact development and disease pathogenesis. Whilst the genome not only consists of the linear composition of DNA, including coding, non-coding and repetitive sequences, the organization of these elements within the genome and how DNA is packed into chromosomes is crucial to maintain a proper genome organization across the nuclear space and time. In addition, genomic alterations also contribute to variations within the population and the speciation process.
Today, many different approaches are available to help understand chromosome and chromatin biology in the context of genome architecture. State-of-the-art technical developments are high and super resolution microscopy, single cell in vivo techniques, methods that can resolve chromatin interactions, such as chromatin conformation capture (3C) approaches and their next generation sequencing methods, as well as chromosomal microarrays as a routine diagnostic tool. Considering advantages, pitfalls, and limitations of the mentioned techniques, chromosome biology can be integrated into personalized medicine. This links basic research with routine diagnostics of genomic diseases and vice versa. Accordingly, clinical genetics also provides huge amounts of data and metadata that can be used in accessible databases to better understand the molecular pathogenesis of disease. To accomplish this aim, integrated genomic data can provide a more comprehensive picture on the fundamental aspects of molecular disease mechanisms in respect to the higher order genome architecture and genome evolution. Collectively, the three-dimensional organization of DNA into chromosomes is directly relevant for gene expression in health and in disease and serves as an additional layer of genomic information.

The aim of this Research Topic is to bring together state-of-the-art methodological approaches and applications, basic research on chromosomal structure, nuclear architecture, and organization, as well as manuscripts with ideas on future directions of chromosome and chromatin biology as Original Research articles, Case Reports, Hypothesis, and new Methods papers. The general scope includes two subparts:
1) Integrative aspects of structure, function, and evolution of the genome for a better understanding of chromosome biology.
2) Towards clinical applications of new technical developments in chromosome biology.
The Research Topic will cover the following areas in particular:
• Evolutionary (human, mammals) conservation, flexibility, and adaption in different levels of genome organization (e.g. linear, 3D, 4D).
• Normal and impaired chromosome behavior, due to chromosomal alterations with respect to each other and during development (e.g. “chromosome kissing”).
• Mechanisms of DNA repair to keep genome integrity intergenerational but also flexible for adaptive evolutionary changes.
• Discovery and characterization of fragile sites in different tissues.
• In vivo / real-time studies on repair of induced chromosome breaks.
• Chromosomal organization and information during cell division (e.g. epigenetic information safely passed on to next generation).
• Historical, current and novel technical developments to study chromosomes and the genome.
• How to uncover somatic mosaicism?
• Contributions of diagnostics to resolve questions of fundamental chromosome biology (e.g. chromothripsis, recurrent rearrangements, breakpoint reuse).
• Case reports on rare nuclear reorganization, chromosomal rearrangements, and copy number variations.
• Outlook, hypotheses, and opinions on the future direction of chromosome biology in the age of molecular genetics.

This topic has been realized, and is in collaboration with Dr Constanze Pentzold , Post Doctoral Researcher at the Institute of Human Genetics, University Hospital Jena.

Keywords: Genome architecture, Long range chromatin interaction, Chromosome (in)stability including fragile sites, Chromosome evolution, (re)Implementation of chromosomes in diagnostics

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
