    Sex-specific role of galectin-3 in aortic stenosis

    Background: Aortic stenosis (AS) is characterized by infammation, fbrosis, osteogenesis and angiogenesis. Men and women develop these mechanisms diferently. Galectin-3 (Gal-3) is a pro-infammatory and pro-osteogenic lectin in AS. In this work, we aim to analyse a potential sex-diferential role of Gal-3 in AS. Methods: 226 patients (61.50% men) with severe AS undergoing surgical aortic valve (AV) replacement were recruited. In AVs, Gal-3 expression and its relationship with infammatory, osteogenic and angiogenic markers was assessed. Valve interstitial cells (VICs) were primary cultured to perform in vitro experiments. Results: Proteomic analysis revealed that intracellular Gal-3 was over-expressed in VICs of male AS patients. Gal-3 secretion was also higher in men’s VICs as compared to women’s. In human AVs, Gal-3 protein levels were signifcantly higher in men, with stronger immunostaining in VICs with myofbroblastic phenotype and valve endothelial cells. Gal-3 levels in AVs were positively correlated with infammatory markers in both sexes. Gal-3 expression was also posi tively correlated with osteogenic markers mainly in men AVs, and with angiogenic molecules only in this sex. In vitro, Gal-3 treatment induced expression of infammatory, osteogenic and angiogenic markers in male’s VICs, while it only upregulated infammatory and osteogenic molecules in women-derived cells. Gal-3 blockade with pharma cological inhibitors (modifed citrus pectin and G3P-01) prevented the upregulation of infammatory, osteogenic and angiogenic molecules. Conclusions: Gal-3 plays a sex-diferential role in the setting of AS, and it could be a new sex-specifc therapeutic target controlling pathological features of AS in VICs.

    Characterization of the sex-specific pattern of angiogenesis and lymphangiogenesis in aortic stenosis
    (Frontiers Media, 2022) Matilla Cuenca, Lara; Martín Núñez, Ernesto; Garaikoetxea Zubillaga, Mattie; Navarro, Adela; Vico, Julieta Anabela; Arrieta Paniagua, Vanessa; García Peña, Amaia; Fernández Celis, Amaya; Gaínza Calleja, Alicia; Álvarez, Virginia; Sádaba Sagredo, Rafael; López Andrés, Natalia; Jover, Eva; Ciencias de la Salud; Osasun Zientziak
    Objective: We aim to analyze sex-related differences in angiogenesis and lymphangiogenesis in aortic valves (AVs) and valve interstitial cells (VICs) from aortic stenosis (AS) patients. Approach and Results: Totally 230 patients (59% men) with severe AS undergoing surgical valve replacement were recruited. The density of total neovessels was higher in AVs from men as compared to women. Both small and medium neovessels were more abundant in men's AVs. Accordingly, male AVs exhibited higher CD31 and VE-cadherin expressions. The levels of the pro-angiogenic markers, such as vascular endothelial growth factor (VEGF)-A, VEGF receptor (VEGFR)1, VEGFR2, insulin-like growth factor-binding protein-2 (IGFBP-2), interleukin (IL)-8, chemerin, and fibroblast growth factor (FGF)-7, were increased in AVs from men. Transforming growth factor-¿ expression was higher in male AVs. The expression of antiangiogenic molecules thrombospondin (Tsp)-1, endostatin, and CD36 was upregulated in male AVs, although the levels of Tsp-2, IL-4, IL-12p70, and chondromodulin-1 were similar between both sexes. The number of lymphatic vessels and the expression of the lymphangiogenic markers Lyve-1 and D2-40 was higher in men's AV as well as VEGF-C, VEGF-D, and VEGFR3. Multivariate analyses adjusted for confounders further validated the sex-dependent expression of these targets. VICs isolated from men's AVs secreted higher amounts of the pro-angiogenic factors, VEGF-A, VEGFR1, IGFBP-2, and FGF-7, as well as the pro-lymphangiogenic factors, VEGF-C, VEGF-D, and VEGFR3, than women without changes in antiangiogenic markers. Conclusion: Our data show that aberrant angiogenic and lymphangiogenic cues are over-represented in male AVs. Importantly, the VIC is a relevant source of multiple morphogens involved in angiogenesis and lymphangiogenesis likely endowing the AV of men with the predominant calcific AS phenotypes.
