Investigate the role of chemotherapy-induced cellular senescence in driving skeletal deterioration and evaluate whether senolytic treatment can mitigate bone loss in young and aged mice.
Treated young (3-month-old) and aged (20-month-old) male and female mice with the chemotherapeutic agent doxorubicin, the senolytic combination dasatinib/quercetin, or a combined regimen.
Assessed skeletal aging markers, osteogenic gene expression (Alpl, Runx2, Dmp1), marrow adiposity, and cortical bone proteomic profiles.
Doxorubicin induced accelerated skeletal aging marked by trabecular bone loss, increased marrow adiposity, and a metabolic shift toward glycolysis, with effects being sex- and age-dependent and most pronounced in females.
Dasatinib/quercetin senolytic therapy partially restored osteogenic gene expression, reduced marrow adiposity—especially in aged females—and partially reversed extracellular matrix remodeling signatures.
Despite notable molecular and proteomic improvements in bone architecture markers, structural recovery of trabecular bone remained modest.
