Artigo Baccharis trimera (Less.) DC exhibits an anti-Adipogenic effect by inhibiting the expression of proteins involved in adipocyte differentiation(MDPI, 2017-06-12) Nascimento, Daniele de Souza Marinho do; Oliveira, Ruth Medeiros; Câmara, Rafael Barros Gomes da; Gomes, Dayanne Lopes; Monte, Jessika Fernanda Santiago; Costa, Mariana Santana Santos Pereira; Fernandes, Júlia Moraes; Langassner, Silvana Maria Zucolotto; Rocha, Hugo Alexandre de OliveiraBaccharis trimera (Less.) DC (gorse) is a plant popularly used for the treatment of obesity. In this study, we prepared three B. trimera extracts aqueous extract (AE), decoction (AE-D), and methanol extract (ME) and investigated their antioxidant effects in six different tests and their anti-adipogenic effect in 3T3-L1 cells. The extracts showed a dose-dependent antioxidant activity in all tests. AE was the most potent antioxidant in copper and ferric ion chelation assays, whereas AE-D was the most potent in superoxide and hydroxyl radical scavenging assays, reducing power assay, and total antioxidant capacity analysis. Only ME showed a cytotoxic effect against 3T3-L1 cells. Lipid accumulation decreased in 3T3-L1 adipocytes in the presence of AE and AE-D extracts (0.5 to 1.0 mg/mL). In addition, the extracts dramatically attenuated the levels of adipogenic transcriptional factors, including CCAAT enhancer-binding protein α (C/EBPα), CCAAT enhancer-binding protein β (C/EBPβ), and gamma receptors by peroxisome proliferators (PPARγ), during adipogenesis. AE-D (1.0 mg/mL) caused an approximately 90% reduction in the levels of these molecules. We propose that B. trimera has an anti-adipogenic effect and could be used in the development of functional foods
