Background

The mitochondrion plays a pivotal role in cellular energy production, orchestrated by the oxidative phosphorylation (OXPHOS) machinery governed by nuclear genes and the circular double-stranded mitochondrial DNA molecule (mtDNA).

Due to its close association with OXPHOS complexes and ensuing exposure to reactive oxygen species, mtDNA is susceptible to mutations and damage, lacking protective histones and repair mechanisms. Genetic variations within mtDNA and nuclear DNA genes encoding mitochondrial proteins can disrupt energy production, triggering disease onset through the alteration of NAD+/NAD(P)H levels—essential cofactors for metabolic reactions and reactive oxygen species scavenging.

Mutations in mtDNA are prevalent in both paediatric and age-related diseases, particularly those impacting the nervous, ocular system and tissues, such as the retina. The high energy demands of these tissues lead to increased mutational burdens and heightened oxidative stress. Oxidative stress significantly contributes to ocular pathophysiology, with individual genetic susceptibility influenced by various environmental factors.

For instance, steroid responsiveness, whether endogenous (e.g., stress-induced) or pharmacologic, can influence disease risk, while the roles of other factors like smoking and alcohol consumption remain inconclusive and necessitate further exploration. As optic neuropathies likely result from the interplay of multiple genes (in nuclear and mtDNA), environmental factors, and their interactions, further research is essential to understand the processes underlying mitochondrial dysfunction and excessive reactive oxygen species production. This profound comprehension may provide fresh insights into therapeutic strategies and early interventions for patients with ophthalmic diseases.

In this Research Topic, we invite original research, full reviews, or mini-reviews that shed light on the role of genetic variations linked to mitochondrial dysfunction in causing ophthalmic diseases and
related conditions in somatic and germline cells. This topic encompasses, but is not limited to:
• Genetic variations across different ethnicities
• Approaches like gene therapy and genome editing to enhance mitochondrial function
• Gene-gene interactions within nuclear and/or mtDNA genomes
• Gene-environment interactions involving nuclear and/or mtDNA genomes
• Risk estimation based on individual genetic susceptibility

We would like to acknowledge Dr. Valeria Lo Faro (Uppsala University, Sweden) as the Topic Coordinator who has contributed to the proposal for this Research Topic. Dr. Lo Faro's research interests are focused on investigating the genetic factors that underlie glaucoma and complex human diseases.

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • 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.

    Check available article types here 

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

     

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.

  • Research Topics thrive on collaboration and their multi-disciplinary approach around emerging, cutting-edge themes, attract leading researchers from all over the world.

  • As a topic editor, you can set the timeline for your Research Topic, and we will work with you at your pace. Typically, Research Topics are online and open for submissions within a few weeks and remain open for participation for 6 – 12 months. Individual articles within a Research Topic are published as soon as they are ready.
