Temporal accumulation of Rev-erbα mRNA and Bmal1 mRNA in vole kidney. Kidney RNAs of voles fed ad libitum (ZT00 and ZT24) (Left) or exclusively between ZT12 and ZT04 were analyzed by Northern blot hybridization as described in Fig. 3 (Upper), and the signals obtained by autoradiography were quantified as described for Fig. 3B (Lower). The voles were housed without running wheels.
