Medial arterial calcification associated with hyperphosphatemia is a main cause of cardiovascular mortality in patients with chronic kidney disease (CKD), but the mechanisms underlying high phosphate-induced vascular calcification remain largely unknown. Here, we observed a significant decrease in the expression of peroxisome proliferator-activated receptor-gamma (PPARγ) in calcified arteries both in CKD patients and in a mouse model of CKD with hyperphosphatemia. In vitro, high phosphate treatment led to a decreased expression of PPARγ in mouse vascular smooth muscle cells (VMSCs), accompanied by apparent osteogenic differentiation and calcification...
