Peptide–oligonucleotide nanohybrids deliver miRNA to injured bone in rats

A Nature Communications study reports a peptide–oligonucleotide nanohybrid for bone-targeted miR-26a-5p delivery. The original abstract describes reduced GSK-3β expression and stabilization of HIF-1α, supporting coupled bone formation and angiogenesis. Systemic administration limited skeletal and vascular injury in a rat glucocorticoid-induced bone-loss model. This is preclinical miRNA delivery, not oral cyclic peptide therapy or human efficacy evidence.
