Parabiosis of SCN-lesioned mice to intact partners fails to reinstate circadian rhythms of relative mPer1, mPer2, and mBmal1 gene expression in heart, spleen, and skeletal muscle. The nonlesioned animals (intact partners) show ZT1 and ZT13 patterns similar to those of mice in intact–intact pairs, whereas the brain-damaged mice (SCN-lesioned partners) showed no significant rhythms in mRNA values. Symbols are as in Fig. 1.
