Discovered 'Switch' That Strengthens Bones: Scientists Finally Know Why, Here's How Exercise Helps Us and What Else It Can Do!
Osteoporosis is a disease that weakens bones and affects tens of millions of people, and long-awaited new therapies could be on the horizon after researchers discovered a key mechanism by which exercise strengthens bones.
TL;DR
- Scientists discovered the Piezo1 protein, which converts movement into stronger bones.
- This protein acts as an 'exercise sensor' in bones, promoting bone growth and reducing fat.
- The discovery could lead to new therapies for osteoporosis, benefiting those who cannot exercise.
- Piezo1's mechanism involves directing mesenchymal stem cells towards bone-building cells instead of fat cells.
- Experiments on mice showed that removing Piezo1 reduced bone density and the benefits of exercise.
- Future therapies could potentially mimic Piezo1's activation to achieve exercise benefits without physical movement.
- More research is needed as the study was on mice, and Piezo1 has multiple roles in the body.
