Abstract:
The coexistence of osteoporosis and sarcopenia is recognized as a syndrome known as osteosarcopenia. As an aging-related disease, research into the molecular mechanisms of osteosarcopenia has gradually shifted from the study of single-organ pathology to the elucidation of multidimensional interactions. This review aims to construct a hierarchical framework of "intracellular - intercellular - systemic" to systematically elaborate on the pathogenesis of osteosarcopenia. Based on this foundation, it explores frontier interventions and their prospects for clinical transformation, including bone-targeting F6-(DSS)6-exo nanoparticles, miR-495, natural active compounds (resveratrol, nuciferine), Clostridium butyricum, and bimagrumab. Future research should focus on analyzing the microenvironment of the musculoskeletal interface, utilizing deep learning CT analysis for early risk identification, and exploring the application of biomaterials in osteomuscular regeneration. This review aims to provide a reference for the field of mechanism research in osteosarcopenia and offer new insights for its precision prevention and treatment.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Initiation of Translation
First, the initiator tRNA must be selected from the pool of elongator tRNAs by eukaryotic initiation factor 2 (eIF2). The initiator tRNA (Met-tRNAi) has conserved sequence elements including modified bases at...
