Summary
Hibernating brown bears offer insights into human health. Their plasma proteomics reveal adaptations to prolonged inactivity and obesity, suggesting potential therapeutic targets for human metabolic disorders.
Area of Science:
- Proteomics
- Comparative Physiology
- Mammalian Hibernation
Background:
- Brown bears hibernate for extended periods, remaining obese and inactive without apparent ill effects.
- This unique physiological state makes hibernating bears a valuable translational model for human metabolic diseases.
Purpose of the Study:
- To present mass-spectrometry based plasma proteomics data from hibernating and active Scandinavian brown bears.
- To identify proteins involved in hibernation adaptations and potential therapeutic targets.
Main Methods:
- Plasma samples from 14 brown bears (hibernating and active states) were analyzed.
- Proteins were processed, digested, and analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
- Data analysis involved MaxQuant software against a brown bear protein database.
Main Results:
- Provided raw proteomics data, identified proteins, and applied databases.
- Enables identification of differentially expressed proteins between hibernation and active states.
- Highlights proteins potentially crucial for hibernation physiology.
Conclusions:
- Hibernating bears exhibit unique plasma proteomic profiles.
- These profiles may offer novel therapeutic targets for human conditions like obesity and inactivity-related complications.
- The study provides a foundation for further research into bear hibernation adaptations.
