Description | The type IIa sodium-dependent phosphate co-transporter (Npt2a) is important to maintain renal inorganic phosphate (Pi) homeostasis and the plasma Pi levels. It has reported that disorder of Pi metabolism in kidney can be risk factors for cardiovascular disease as well as hypercholesterolemia. However, the relationship between Pi and cholesterol metabolism has not been clarified. The current study investigated the effects of Npt2a gene ablation that is known as hypophosphatemia model on cholesterol metabolism in mice. Npt2a deficient (Npt2a-/-) mice and wild type mice were fed diets with or without 2% cholesterol for 12 days. Plasma lipid and lipoprotein profile analysis revealed that plasma lipid levels (total, LDL and HDL cholesterol) were significantly higher in Npt2a-/- mice than wild type (WT) mice. Interestingly, high cholesterol diet markedly increased plasma levels of total, LDL and HDL cholesterol in WT mice, but not Npt2a-/- mice. On the other hand, there were no differences in body and liver weight, intake and hepatic lipid accumulation between WT and Npt2a-/- mice. These results suggest that ablation of Npt2a gene induces hypercholesterolemia and affects the ability to respond normally to dietary cholesterol.
