Abstract:

Kaempferol (KPF) is a dietary polyphenol reported to have various beneficial effects on human health. However, its molecular mechanisms in regulating lipid and glucose metabolism are not fully understood. This study examined the effects of KPF on obesity, dyslipidemia, and diabetes in Tsumura, Suzuki, Obese Diabetes (TSOD) mice. The six-week administration of KPF decreased fat weight, serum total cholesterol, and low-density lipoproteins (LDLs); increased high-density lipoproteins (HDLs); and improved glucose tolerance. Additionally, KPF increased LDL receptor (LDLR) and apolipoprotein A1 (ApoA1) gene expression and decreased serum resistin levels. These findings suggest that the decrease in LDL and the increase in HDL caused by KPF may be due to increases in hepatic LDLR and ApoA1 expression, respectively. Furthermore, it is possible that the improvement in glucose tolerance by KPF may occur via resistin reduction. These mechanisms may be parts of complex mechanism by which KPF improves metabolic syndrome.
