In light of the fact that its association appears specific to AAA—without clear links to other common cardiovascular or metabolic traits—LINC00540 is postulated to be involved in the vascular remodeling, inflammatory responses, or extracellular matrix dynamics that characterize aneurysm formation and progression. Future functional studies will be critical to elucidate the specific mechanisms by which LINC00540 contributes to AAA pathogenesis and to assess its potential utility as a biomarker or therapeutic target.\n "}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Weihong Tang, Athanasios Saratzis, Jack Pattee, et al.
