The metabolic and endocrine systems regulate human material metabolism, energy balance, and growth and development through a sophisticated hormonal network. Disruption of this homeostasis can lead to significant health issues such as diabetes, obesity, and growth disorders. Lifestyle factors including poor diet (e.g., diets high in processed foods, refined carbohydrates, and additives), sedentary behavior, insufficient sleep, and stress are critical triggers for endocrine dysfunction. These factors not only directly contribute to obesity but also alter metabolic signaling and induce systemic inflammation through reactive oxygen species (ROS) generated by exposome factors,

Muscle and tissue repair are core physiological processes that maintain motor function, structural integrity, and post-injury functional reconstruction. These processes involve complex mechanisms such as cell proliferation, extracellular matrix (ECM) remodeling, angiogenesis, and inflammatory microenvironment regulation. Key scenarios in this field—including muscle growth, wound healing, joint repair, and sports injury recovery—rely on precise interventions in satellite cell activation, fibroblast function, cartilage matrix metabolism, and neuromuscular junction repair. Peptide substances, with their high biological activity and target specificity, can specifically modulate cellular signaling pathways, promote tissue regeneration, and inhibit fibrosis. They are emerging as critical tools to overcome bottlenecks in traditional repair therapies and demonstrate broad application prospects in sports medicine, trauma surgery, and regenerative medicine.
