Scope:
Maple syrup contains various polyphenols and we investigated the effects of a polyphenol-rich maple syrup extract (MSXH) on the physiology of mice fed a high-fat diet (HFD).
Methods And Results:
The mice fed a low-fat diet (LFD), an HFD, or an HFD supplemented with 0.02% (002MSXH) or 0.05% MSXH (005MSXH) for 4 weeks. Global gene expression analysis of the liver was performed, and the differentially expressed genes were classified into three expression patterns; pattern A (LFD < HFD > 002MSXH = 005MSXH, LFD > HFD < 002MSXH = 005MSXH), pattern B (LFD < HFD = 002MSXH > 005MSXH, LFD > HFD = 002MSXH < 005MSXH), and pattern C (LFD < HFD > 002MSXH < 005MSXH, LFD > HFD < 002MSXH > 005MSXH). Pattern A was enriched in glycolysis, fatty acid metabolism, and folate metabolism. Pattern B was enriched in tricarboxylic acid cycle while pattern C was enriched in gluconeogenesis, cholesterol metabolism, amino acid metabolism, and endoplasmic reticulum stress-related event.
Conclusion:
Our study suggested that the effects of MSXH ingestion showed (i) dose-dependent pattern involved in energy metabolisms and (ii) reversely pattern involved in stress responses.
