Inorganic Phosphate Modulates the Expression of the NaPi-2a Transporter in the trans-Golgi Network and the Interaction with PIST in the Proximal Tubule

Figure 2

Expression of NaPi-2a (red) and PIST (green) in rat proximal tubules fed chronically (24 h) a low (0.1%) or high (1.2%) Pi diet. Colocalization only takes place intracellularly in high Pi diet fed animals (arrows). Nuclei stained with DAPI (blue).
