From Collapse to Active Self-Repair: Integrative Multi-Omics and Machine Learning Analysis Map the Hepatic Metabolic
Summary
Simulated spaceflight causes liver injury and metabolic dysfunction in rats, with incomplete recovery. This study identifies key molecular pathways involved in hepatic adaptation to space, offering targets for astronaut health.
Area of Science:
- Space biology
- Hepatology
- Metabolomics
Background:
- Long-term spaceflight presents significant physiological challenges, particularly affecting the liver.
- Understanding hepatic adaptation is crucial for astronaut health during extended missions.
Purpose of the Study:
- To investigate hepatic alterations in response to simulated spaceflight conditions.
- To determine if these changes are transient or represent sustained remodeling.
- To identify molecular targets for mitigating spaceflight-induced liver injury.
Main Methods:
- Integrated multi-omics analysis (histopathology, cytokine/miRNA profiling, proteomics, metabolomics, Western blot).
- AI-driven analysis and machine learning for protein panel identification.
- External validation using NASA GeneLab transcriptomic data.
Main Results:
- Simulated spaceflight induced hepatic atrophy, injury, and NAFLD-like metabolic dysfunction.
- Multi-omics revealed impaired energy metabolism, disrupted lipid regulation, and inflammation.
- Recovery showed partial restoration of mitochondrial function and lipid metabolism, with incomplete histological improvement.
Conclusions:
- Hepatic response involves energy/lipid/mitochondrial regulation, fatty acid utilization, and structural repair signaling.
- Key proteins identified can distinguish injury from recovery states.
- Findings provide insights into liver adaptation and potential therapeutic targets for spaceflight.
