Identification of potential Fgf23 enhancers and production of Fgf23−16KO mice. (A) ChIP-seq tag density (normalized to 107 tags) for histone modifications and CTCF binding across the Fgf23 gene locus in differentiated IDG-SW3 osteocytes. (B) Schematic describing the deletion of the −16kb region from the mouse genome via CRSIPR-Cas9 genome editing.
