Figure Legend Snippet: FGF23 is associated with renal immune cell content in human patients with IgA nephropathy. As a reference, single‐nucleus RNA‐Seq data from 5 human kidney biopsies ( GSE199711 ) of 2 healthy controls and 3 patients with chronic kidney disease (CKD) were reanalyzed and annotated (A); see also Supporting Information Figure . 35 patients with IgA nephropathy from the Karolinska Kidney Biopsy Cohort showed an inverse univariable association between circulating FGF23 and measured glomerular filtration rate (GFR) (B). The associations between transcriptome‐inferred renal fibroblasts and immune cells (C–D) or macrophages (E–F) and circulating FGF23 are shown, with adjustment for GFR, 25OH‐vitamin D and parathyroid hormone. (D, F) Show disaggregated data stratified by GFR in CKD stages I–II and III–V.

Article Snippet: Funding information Deutsche Forschungsgemeinschaft (DFG), Grant/Award Number: Li9487/1; Hannover Medical School, Grant/Award Number: HilF/ LifeScience Stiftung München Abstract Dietary phosphate intake in the Western population greatly exceeds the recommended dietary allowance and is linked to enhanced cardiovascular and allcause mortality.. It is unclear whether a chronic high phosphate diet (HPD) causes kidney injury in healthy individuals.. Here, we show that feeding a 2% HPD in C57BL/6N mice for one up to six months resulted in hyperphosphatemia, hyperphosphaturia, increased plasma levels of fibroblast growth factor (FGF) 23, and parathyroid hormone (PTH) compared to mice on a 0.8% phosphate diet. |
