Yoda1 Restores Bone Response
Researchers published an article in Aging Cell on August 21 about experiments on 19-month-old mice. The substance Yoda1, combined with a two-week cyclic compression of the tibia, initiated the formation of new tissue in its outer layer. When researchers blocked two links in the signal transmission within bone cells, the effect disappeared.
The bone responds to regular stress by adding to its cortical layer, its dense outer shell. Osteocytes, cells within this tissue, first detect deformation. In 16-week-old mice, two-week cyclic compression of the tibia enhanced cortical bone formation. In 19-month-old animals, the same regimen no longer changed its basic parameters.
The authors chose Piezo1, an ion channel in the osteocyte membrane sensitive to deformation, and Yoda1, which reduces the deformation threshold at which this channel opens. In the new experiment, Yoda1 was administered to 19-month-old males an hour before compression. The combination of the drug and stress reduced the bone marrow cavity and increased the area and thickness of the cortical layer.

Piezo1 Activation Rescues Anabolic Response to Mechanical Loading in Aged Bone via Connexin 43 Hemichannels
Bone mechanosensitivity declines with age, resulting in a reduced anabolic response to mechanical stimulation. Although the mechanosensitive ion channel Piezo1 plays a critical role in bone mechanoresponsiveness, its mechanisms of ...
