Title: Microgravity-Induced Changes in Cellular Repair Mechanisms During Long-Duration Spaceflight

Introduction/Background: Extended exposure to microgravity presents significant challenges to cellular integrity, particularly in the context of DNA damage and repair. This study investigates the impact of long-duration spaceflight on cellular repair mechanisms using human epithelial cell cultures aboard a low Earth orbit platform.

Methods: Samples were collected at multiple time points over a six-month mission and compared to ground-based controls maintained under simulated Earth gravity conditions.

Results: The findings demonstrate a measurable decrease in the efficiency of double-strand DNA break repair in microgravity-exposed cells, accompanied by altered expression of key regulatory genes involved in genomic stability. Notably, cells demonstrated increased susceptibility to oxidative stress, suggesting compounding effects from the spaceflight environment. Post-flight recovery analysis revealed partial restoration of repair function, though some alterations persisted, indicating potential long-term biological consequences.

Conclusion: These findings contribute to a growing understanding of how microgravity affects fundamental cellular processes and highlight the need for targeted countermeasures to protect astronaut health during extended missions. Future work will focus on pharmacological and environmental interventions to mitigate these effects.

Abstract Changes:

You can make changes to your abstract at any time before the submission deadline by logging into your X-CD profile. After the submission deadline, no changes are allowed.

Multiple Abstract Submissions: 

You may be an author on more than one abstract. However, an individual should generally avoid being listed as the presenting author, usually the first author, on multiple abstracts. In some cases, a person may have both a presentation and a poster, but these situations are reviewed individually during the evaluation process.

Confirmation of Abstract Submission: 

You will receive a confirmation email once your abstract has been successfully submitted.

Abstract Selection:

Abstracts are grouped by discipline and evaluated by peer scientists with no conflicts of interest. The meeting organizing committee, under the guidance of the technical conference chair, determines the placement and order of abstracts in the program.

Notification about abstract selection will be emailed no earlier than August 1, 2026. If your abstract is accepted, the email will include your placement in the program, including date, time, and session type (oral or poster). The session date and time for your abstract are final and cannot be changed.

You must register for the conference by September 30, 2026, to be eligible to present.

High School and Middle School Abstracts:

A separate call for secondary school students to submit abstracts will be issued in July 2026.
