Figure 1: Stability of reference gene (RG) expression at either daytime or night time in the hearts of mice fed either a control (A and C) or high fat diet (B and D). Housekeeping gene expression in individual groups; * = the most stably expressed RGs, whereas # = the least stable RGs. (E.) Stability ranking for all groups. (F.) Mean Ct value�SEM for each gene when all groups and time points are combined.
