To evaluate the effect of furosemide treatment on Ca2+ handling, renal expression levels of TRPV5 and the cytosolic Ca2+-binding protein calbindin-D28K in the late DCT (DCT2) and CNT were determined. Furosemide significantly increased the mRNA expression levels of TRPV5 (125 �� 6 and 100 �� 6%, furosemide versus control, P selleck chemicals 13 and 100 �� 8%, furosemide versus control, P AP24534 furosemide versus control, P > 0.05. UNC2881 Finally, the mRNA expression level of the Na+�CH+ exchanger 3 (NHE3) in the proximal tubule (PT) and to a minor extent in TAL [31, 32] was determined to define whether chronic furosemide treatment increased Na+ reabsorption in the PT. Furosemide treatment did not substantially change the renal mRNA level of NHE3 (125 �� 17 and 100 �� 6%, furosemide versus control, P > 0.1) (Figure 4E). Fig. 3. Effect of chronic furosemide treatment on renal TRPV5 and calbindin-D28K expression levels. Real-time qPCR was used to determine the mRNA expression levels of the epithelial Ca2+ channel TRPV5 (A) and the cytosolic Ca2+-binding protein calbindin-D28K ... Fig. 4. Effect of chronic furosemide treatment on renal PV, CLDN7, CLDN8, ENaC and NHE3 mRNA expression levels. Real-time qPCR was used to determine mRNA levels of parvalbumin (PV) (A), claudin-7 (CLDN7) (B), claudin-8 (CLDN8) (C), the epithelial Na+ channel ... Ultimately, to confirm our data obtained by real-time qPCR and IHC, we performed immunoblotting for NCC, calbindin-D28K and ��ENaC. Quantification of the immunoblots revealed that NCC (165 �� 15 and 100 �� 10%, furosemide versus control, P
