Abstract:
Obesity is a condition caused by surplus adipose tissue and is a risk factor for several diet-related diseases. Obesity is a global epidemic that has also been challenging to treat effectively. However, one promoted therapy to safely treat obesity is anti-adipogenic therapeutics. Therefore, identifying potent anti-adipogenic bioactive compounds that can safely be used clinically may effectively treat obesity in humans. Mango leaf has potential medicinal properties due to its many bioactive compounds that may enhance human health. Mangiferin (MGF) is a primary constituent in mango plants, with many health-promoting qualities. Therefore, this study investigated the effect of MGF, and tea brewed with mango leaves in cultured adipocytes. The anti-adipogenic efficacy of mango leaf tea (MLT) and MGF in 3T3-L1 cells were assessed, along with cell viability, triglyceride levels, adiponectin secretion, and glucose uptake analyzed. In addition, changes in the mRNA expression of genes involved in lipid metabolism within 3T3-L1 cells were determined using quantitative real-time PCR. Our results showed while both MLT and MGF increased glucose uptake in adipocytes, only MLT appeared to inhibit adipogenesis, as determined by decreased triglyceride accumulation. We also observed increased secretory adiponectin levels, reduced ACC mRNA expression, and increased FOXO1 and ATGL gene expression in 3T3-L1 cells treated with MLT but not MGF. Together, these results suggest that MLT may exhibit anti-adipogenic properties independent of MGF content.
Insights
Mango leaf tea (MLT) shows anti-adipogenic effects by reducing fat accumulation and enhancing glucose uptake in fat cells. These benefits appear independent of mangiferin (MGF), a key mango leaf compound.
Area of Science:
- Biochemistry
- Cell Biology
- Nutraceuticals
Background:
- Obesity is a global health crisis, often linked to diet and challenging to treat.
- Anti-adipogenic therapeutics offer a promising strategy for safe and effective obesity management.
- Mango leaves contain bioactive compounds with potential health benefits, including anti-obesity properties.
Purpose of the Study:
- To investigate the anti-adipogenic effects of mango leaf tea (MLT) and its primary compound, mangiferin (MGF).
- To assess the impact of MLT and MGF on adipocyte differentiation, lipid metabolism, and glucose uptake in 3T3-L1 cells.
Main Methods:
- Cultured 3T3-L1 adipocytes were treated with MLT and MGF.
- Assessed cell viability, triglyceride accumulation, and adiponectin secretion.
- Analyzed glucose uptake and mRNA expression of lipid metabolism genes (ACC, FOXO1, ATGL) via quantitative real-time PCR.
Main Results:
- Both MLT and MGF increased glucose uptake in adipocytes.
- MLT, but not MGF, significantly inhibited adipogenesis by reducing triglyceride accumulation.
- MLT treatment led to increased adiponectin secretion and altered expression of key lipid metabolism genes (decreased ACC, increased FOXO1 and ATGL).
Conclusions:
- Mango leaf tea (MLT) demonstrates anti-adipogenic properties in 3T3-L1 cells.
- The anti-adipogenic effects of MLT may be mediated by mechanisms independent of its mangiferin (MGF) content.
- MLT warrants further investigation as a potential therapeutic agent for obesity and related metabolic disorders.
