Administration of short chain fatty acids (SCFA) changed the phase of clock gene expression rhythms in the kidney of antibiotic-induced microbiota depleted mice. (A) Similar to Fig. 1A, antibiotic-induced microbiota depleted mice were orally gavaged SCFA + lactate mix (400 mM in each) at ZT5 for three consecutive days; then, kidneys were collected every 4 hours for 24 hours starting at ZT7 after the last injection. (B) Clock gene expression measured by RT-PCR. Peak phase analysis is shown in Table S3. Gene expression levels were normalized to Gapdh. All the values are expressed as mean ± SEM. P value of the two-way ANOVA is indicated in the lower right side of each graph if significant. **p < 0.01, ***p < 0.001, vs. vehicle gavaged group (Sidak’s multiple comparisons test).
