Stevia rebaudiana Bertoni is famous for sweetness due to the content of steviol glycosides (SG). This study aimed to determine the effect of SG (stevioside, rebaudioside A) and steviol on adipogenesis and lipogenesis in the 3T3-L1 model. Test compounds were also analysed for their ability to affect glucose uptake in hypertrophied insulin-resistant 3T3-L1 adipocytes. The most active compound in modulating adipogenesis, lipogenesis and insulin resistance was steviol, SG metabolism product. Steviol (10 μM, 100 μM) significantly down-regulated the expression of adipogenic transcription factors (PPARγ, C/EBPα, SREBP1) and lipogenic genes (FAS, aP2, LPL), which caused decreased lipid accumulation and triglyceride content in adipocytes. Treatment of insulin-resistant adipocytes with steviol (1 μM) and stevioside (1 μM, 10 μM) increased GLUT-4 transcript level and improved glucose uptake. Steviol also lowered resistin gene expression, which may mitigate insulin resistance in hypertrophied adipocytes. This study promotes SG as potential health-promoting ingredients in low-calorie functional foods. |
