Modulation of Osteogenic Gene Expression by Human Osteoblasts Cultured in the Presence of Bisphenols BPF, BPS, or BPAF García Recio, Enrique Costela Ruiz, Víctor Javier Illescas Montes, Rebeca Melguizo Rodríguez, Lucía Raquel García Martínez, Olga Ruiz Rodríguez, Concepción Luna Bertos, María Elvira De Bisphenol S (BPS) Bisphenol F (BPF) Bisphenol AF Osteoblast Gene expression Bone effects attributed to bisphenols (BPs) include the inhibition of growth and differentiation. This study analyzes the effect of BPA analogs (BPS, BPF, and BPAF) on the gene expression of the osteogenic markers RUNX2, osterix (OSX), bone morphogenetic protein-2 (BMP-2), BMP-7, alkaline phosphatase (ALP), collagen-1 (COL-1), and osteocalcin (OSC). Human osteoblasts were obtained by primary culture from bone chips harvested during routine dental work in healthy volunteers and were treated with BPF, BPS, or BPAF for 24 h at doses of 10−5, 10−6, and 10−7 M. Untreated cells were used as controls. Real-time PCR was used to determine the expression of the osteogenic marker genes RUNX2, OSX, BMP-2, BMP-7, ALP, COL-1, and OSC. The expression of all studied markers was inhibited in the presence of each analog; some markers (COL-1; OSC, BMP2) were inhibited at all three doses and others only at the highest doses (10−5 and 10−6 M). Results obtained for the gene expression of osteogenic markers reveal an adverse effect of BPA analogs (BPF, BPS, and BPAF) on the physiology of human osteoblasts. The impact on ALP, COL-1, and OSC synthesis and therefore on bone matrix formation and mineralization is similar to that observed after exposure to BPA. Further research is warranted to determine the possible contribution of BP exposure to the development of bone diseases such as osteoporosis. 2023-04-12T10:17:53Z 2023-04-12T10:17:53Z 2023-02-21 info:eu-repo/semantics/article García-Recio, E.; Costela-Ruiz, V.J.; Illescas-Montes, R.; Melguizo-Rodríguez, L.; García-Martínez, O.; Ruiz, C.; De Luna-Bertos, E.
