Nprc mRNA expression during 3T3-L1 adipocyte differentiation.A–C, mRNA levels of Nprc (A), Fabp4 (B), and Pparγ1/2 (C) during 3T3-L1 adipocyte differentiation. Data were normalized with 36B4. D, protein levels of NPRC, FABP4, PPARγ1/2, and ADIPOQ during 3T3-L1 adipocyte differentiation (Day 0, 2, 4, and 6). FABP4, fatty acid–binding protein 4; Nprc, NP receptor C; PPARγ1/2, peroxisome proliferator–activated receptor gamma1/2.
