CD36 and GPR120 mRNA transcripts display different diurnal rhythms in mouse circumvallate papillae.

A: Diurnal rhythm of food intake, plasma triglycerides (TG) and glucose levels in mice fed ad libitum a standard laboratory chow. Means ± SEM (n = 10). B: CD36, GPR120 and α-gustducin mRNA levels determined by real-time PCR in circumvallate papillae from mice fed ad libitum a standard laboratory chow. Insert: comparison of area under the curve (AUC) between the light and the dark periods. Each value corresponds to a pool of total RNA from 2 mice. Means ± SEM (n = 5).
