Updated project metadata. The distal convoluted tubule (DCT) and the cortical collecting ducts (CCD) are portions of renal tubule that are partly responsible for maintaining the systemic concentrations of potassium, sodium, calcium and magnesium. Despite being structurally similar, DCT and CCD cells have different transport capabilities due to a variety of different membrane-associated transport proteins. However, DCT and CCD cells appear to be modulated via the same hormones. The objective of this study was assess the differential response of DCT and CCD cells to long-term exposure to the hormones vasopressin or angiotensin II, both of which modulate DCT and CCD cells differently. Mass spectrometry based quantitative proteomics was used to profile the differential proteome between DCT and CCD.
