Nonetheless, the role of GAL-9 in the context of vascular pathologies has been increasingly investigated as recent observational studies have linked elevated serum levels of GAL-9 and other endothelially expressed galectins to vascular diseases such as coronary artery disease (CHD), stroke, and peripheral artery occlusive disease (PAOD) [36,37,38,39]. Here, LGALS9 is linked to Peripheral arterial stenosis.
