Pain Hypersensitivity in a Mouse Model of Marfan Syndrome.

ABSTRACT: Marfan syndrome (MFS) is a genetic disorder caused by mutations in the fibrillin-1 (Fbn1) gene, leading to structurally abnormal elastic fibers and diverse clinical manifestations. Aortic root dilation represents the most serious threat, often requiring prophylactic surgical repair. Emerging evidence suggests that MFS patients experience increased pain sensitivity, contributing to functional impairment and reduced quality of life. Here, we used C57BL/6 wild-type and Fbn1^C1041G/+ (MFS) mice to examine brain transcriptomics, aortic histology, nociceptive behaviors, grip strength, and spinal cord gene expression in both sexes at 2, 4, 6, 8, and 16 months of age. Transcriptomic analysis revealed reduced activation of pain-related pathways in young males and aged females, with a reve
