Schematic illustration of myostatin-induced FGF23 production in UMR106 cells. Myostatin binding to ACVR2B and following partnering with TGF-βRI activates p38MAPK and NFκB. NFκB induces SOCE, resulting in induction of Fgf23 gene expression. Created with BioRender.com. Activin type 2 receptor B (ACVR2B); fibroblast growth factor 23 (FGF23); nuclear factor kappa-light-chain-enhancer of activated B-cells (NFκB); p38 mitogen–activated protein kinase (p38MAPK); store-operated Ca2 + entry (SOCE); transforming growth factor-β type I receptor (TGF-βRI)
