Dataset Summary
Title | LC MS/MS of calcium-sensing receptor (CaSR) knockdown in cultured murine podocytes versus wildtype |
Description | Calcimimetic agents allosterically increase the calcium (Ca2+) sensitivity of the calcium-sensing receptor (CaSR), which is expressed in the tubular system and to a lesser extent in podocytes. Activation of this receptor can reduce glomerular proteinuria and structural damage in proteinuric animal models. However, the precise role of the podocyte CaSR is still unclear. A CaSR knockdown in cultured murine podocytes and a podocyte-specific CaSR knockout in BALB/c mice were generated to study its role in proteinuria and kidney function. Podocyte CaSR knockdown abolished the calcimimetic R-568 mediated Ca2+-influx, disrupted the actin cytoskeleton, reduced cellular attachment and migration velocity. Adriamycin (ADR)-induced proteinuria enhanced glomerular CaSR expression in wild type mice. Albuminuria, podocyte foot process effacement, podocyte loss and glomerular sclerosis were significantly more pronounced in ADR-treated podocyte-specific CaSR knockout mice compared to wild type littermates. The co-treatment of WT mice with ADR and the calcimimetic cinacalcet reduced the proteinuria in WT, but not in podocyte specific CaSR knockout mice. In addition, four children with nephrotic syndrome, objecting glucocorticoid therapy, were treated with cinacalcet for 1 to 33 days. Proteinuria declined transiently by up to 96% and edema resolved. The activation of podocyte CaSR regulates key podocyte functions in vitro and reduces toxin induced proteinuria and glomerular damage in mice. Our findings suggest a potential novel role of CaSR signaling in control of glomerular disease. Proteomic samples: two backgrounds (CaSR Knockdown vs WT) two conditions (Treatment = 1µM R568 vs untreated control) two timepoints (24h and 48h) five replicates each 2 x 2 x 2 x 5 = 40 samples |
