About this Research Topic

Background

Maintaining adequate oxygen is pivotal for sustaining cellular metabolism and growth among all mammalian species from the earliest stages of development onwards. Disrupted oxygen balance during critical developmental windows elicits acute physiological responses and persistent modifications to organ systems and disease susceptibility. A deeper understanding of the mechanisms underlying the maintenance of oxygen homeostasis, the consequences to growth and development that occur when homeostatic balance fails, and the temporal nature of such effects will help lay the groundwork for developing early interventions and effective therapies.

Physiological hypoxia is critical for orchestrating transcriptional programs that guide cellular differentiation during embryogenesis and crucial for the initial phases of placentation that are required to sustain fetal oxygenation across gestation. The fetus is exquisitely sensitive to periodic disruptions in oxygen homeostasis which elicit myriad physiologic and metabolic responses to maximize oxygen delivery to critical organ systems. Chronic fetal hypoxia has been linked to the later-in-life development of potentially devastating conditions including, but not limited to, neurological disorders, abnormal growth trajectories, cardiovascular dysfunction, metabolic dysregulation, and pulmonary vascular disease. Exposure to chronic hypoxia such as that of high altitudes during infancy and childhood can also affect postnatal growth trajectories and influence health outcomes. This research topic welcomes contributions that improve our understanding of the molecular mechanisms regulating oxygen homeostasis during critical developmental periods, the impact of hypoxia on developmental trajectories and disease susceptibility, and human adaptive potential under conditions of limited oxygen supply.

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 they fall 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.

• Who leads a Research Topic? 

  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.

• What is the role of a topic editor?

  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.
