Expression data from mouse collecting duct cell, mpkCCD, in response to a peptide hormone vasopressin analog, dDAVP

Vasopressin is the major hormone that regulates renal water excretion. It does so by binding to a receptor in renal collecting duct cells, triggering signaling pathways that ultimately regulate the abundance, location, and activity of the water channel protein aquaporin 2. We took an advantage of quantitative large scale proteomic technologies and oligonucleotide microarrays to quantify steady state changes in protein and transcript abundances in response to vasopressin in a collecting duct cell line, mpkCCD clone 11 (Yu et al. PNAS 2009, 106:2441-2446). This cell line originally developed by Alan Vandewalles group recapitulates vasopressin-mediated AQP2 expression and phosphorylation as seen in native colleting duct cells.
