Hypothesis

How does the phosphoproteome change in postmortem mouse brains under different preservation conditions?

Conclusion

The study found that postmortem changes in phosphoproteins are diverse and depend on temperature and time.

Supporting Evidence

  • Phosphoproteins showed extreme diversity in changes postmortem.
  • Most proteins decreased after 12 hours at room temperature.
  • At 4°C, phosphoproteins were stable for up to 72 hours.

Takeaway

When a mouse dies, the proteins in its brain change over time, and how we keep the body can affect these changes.

Methodology

The study analyzed phosphoproteins in mouse brains preserved at different temperatures and times using mass spectrometry.

Limitations

The study focused only on a limited number of proteins and used mouse models, which may not fully represent human conditions.

Participant Demographics

12 week-old C57BL/6J mice were used in the study.
