Phosphorus metabolism disorders articles from across Nature Portfolio

Inositol hexakisphosphate kinase (IP6K) is involved in diverse cellular signalling pathways, but the physiological roles of IP6K in vivo remain unknown in mammals. Here, the authors show that the enzymatic activity of IP6K is essential for phosphate regulation in vivo.

Management of mineral and bone disorders in patients with chronic kidney disease (CKD–MBD) requires an understanding of the complex interactions among ions, hormones and their target organs. Since publication of the KDIGO CKD–MBD guideline in 2009, our understanding of disease pathophysiology has improved; however, a paucity of high-quality clinical evidence to support specific interventions remains. Using available data, KDIGO has now updated diagnostic and therapeutic recommendations for patients with CKD–MBD.

Elevated levels of fibrobast growth factor 23 (FGF-23) are associated with cardiovascular and all-cause mortality in patients with kidney disease. A secondary analysis of the EVOLVE trial reports that cinacalcet-induced reductions in FGF-23 were associated with a reduced risk of cardiovascular events in patients with secondary hyperparathyroidism on dialysis.
