Numbers indicate the count of serial analysis of gene expression (SAGE) tags per 50000.
indicate a significant differential regulation by LF or HF feeding compared to fasting ( 𝑃 . 0 5 ).
* indicates the significant modulation in the HF compared to the LF group at the corresponding time point ( 𝑃 . 0 5 ).
