Calcitonin Inhibits Phenotypic Switching of Aortic Smooth Muscle Cells and Neointimal Hyperplasia through the AMP-Activated Protein Kinase/Mechanistic Target of Rapamycin Pathway.

ABSTRACT: Calcitonin (CT) is a peptide hormone secreted by the parafollicular C cells of the thyroid gland, salmon calcitonin was originally extracted from the hind cheek of salmon. Neointimal hyperplasia refers to the excessive proliferation and migration of vascular smooth muscle cells (VSMCs). In this study, a rat model of restenosis was employed to explore the impact of calcitonin on neointima proliferation. Calcitonin was administered via continuous injections for a duration of 14 days postsurgery, and the expression of proteins associated with proliferation, migration, and phenotypic switching was assessed using the vascular smooth muscle cells. Additionally, metabolomic analyses were conducted to shed light on the mechanisms that underlie the role of calcitonin in the development of cardiovas
