Repercussions of Bisphenol A on the Physiology of Human Osteoblasts García Recio, Enrique Costela Ruiz, Víctor Javier Melguizo Rodríguez, Lucía Raquel Ramos Torrecillas, Javier García Martínez, Olga Ruiz Rodríguez, Concepción Luna Bertos, María Elvira De (1) Background: Bisphenol A (BPA) is an endocrine disruptor that is widely present in the environment and exerts adverse effects on various body tissues. The objective of this study was to determine its repercussions on bone tissue by examining its impact on selected functional parameters of human osteoblasts. (2) Methods: Three human osteoblast lines were treated with BPA at doses of 10(-5), 10(-6), or 10(-7) M. At 24 h post-treatment, a dose-dependent inhibition of cell growth, alkaline phosphatase activity, and mineralization was observed. (4) Results: The expression of CD54 and CD80 antigens was increased at doses of 10(-5) and 10(-6) M, while the phagocytic capacity and the expression of osteogenic genes (ALP, COL-1, OSC, RUNX2, OSX, BMP-2, and BMP-7) were significantly and dose-dependently reduced in the presence of BPA. (5) Conclusions: According to these findings, BPA exerts adverse effects on osteoblasts by altering their differentiation/maturation and their proliferative and functional capacity, potentially affecting bone health. Given the widespread exposure to this contaminant, further human studies are warranted to determine the long-term risk to bone health posed by BPA. 2022-06-14T11:56:33Z 2022-06-14T11:56:33Z 2022-05-11 info:eu-repo/semantics/article García-Recio, E...
