Abstract Backgrounds: Breast cancer metastasis remains the leading cause of mortality and frequently targets the bone. Breast cancer cells release soluble factors and extracellular vesicles that disrupt bone marrow (BM)/bone homeostasis, promoting osteoclastogenesis and the accumulation of senescent cells. In line with updated cancer hallmarks, senescent mesenchymal stem/ stromal cells (MSCs), osteoblasts, and osteocytes contribute to remodeling of the BM microenvironment, thereby favoring pre-metastatic niche (PMN) formation and subsequent bone metastasis. We previously demonstrated that untreated stage III-B breast cancer patients (BCPs) exhibit increased oxidative stress and elevated reactive oxygen species (ROS) levels, accompanied by senescent… More >
