Blocking a specific cell pathway triggers self-cleaning in bone marrow stem cells to change their development and improve osteoporosis

Disrupted bone homeostasis in osteoporosis may be influenced by the RNA-binding protein PTBP1.

• Dysregulated autophagy is associated with impaired bone remodeling and bone loss in osteoporosis.
• PTBP1 may play a role in the progression of osteoporosis through the regulation of protein kinase C zeta (PRKCZ).
• The study explores whether PTBP1 affects the commitment of bone marrow stem cells to become either bone-forming or fat-forming cells via autophagy.
