- A novel supplement with yeast 6-glucan, prebiotic, minerals and Silybum marianum synergistically modulates metabolic and inflammatory pathways and improves steatosis in obese mice(2021) NEHMI, Victor Abou; MURATA, Gilson Masahiro; MORAES, Ruan Carlos Macedo de; LIMA, Gabriely Cristina Alves; MIRANDA, Danielle Araujo De; RADLOFF, Katrin; COSTA, Raquel Galvao Figueredo; JESUS, Joyce de Cassia Rosa de; FREITAS, Jessica Alves De; VIANA, Nayara Izabel; PIMENTA, Ruan; LEITE, Katia Ramos Moreira; OTOCH, Jose Pinhata; PESSOA, Ana Flavia MarcalObjective: To evaluate the synergic effects of a novel oral supplement formulation, containing prebiotics, yeast beta-glucans, minerals and silymarin (Silybum marianum), on lipid and glycidic metabolism, inflammatory and mitochondrial proteins of the liver, in control and high-fat diet-induced obese mice. Methods: After an acclimation period, 32 male C57BL/6 mice were divided into the following groups: nonfat diet (NFD) vehicle, NFD supplemented, high-fat diet (HFD) vehicle and HFD supplemented. The vehicle and experimental formulation were administered orally by gavage once a day during the last four weeks of the diet (28 consecutive days). We then evaluated energy homeostasis, inflammation, and mitochondrial protein expression in these groups of mice. Results: After four weeks of supplementation, study groups experienced reduced glycemia, dyslipidemia, fat, and hepatic fibrosis levels. Additionally, proliferator-activated receptor-alpha, AMP-activated protein kinase-1 alpha, peroxisome proliferator-activated receptor c co-activator-1 alpha, and mitochondrial transcription factor A expression levels were augmented; however, levels of inhibitor of nuclear factor-kappa B kinase subunit a and p65 nuclear factor-kappa B expression, and oxidative markers were reduced. Notably, the cortisol/C-reactive protein ratio, a well-characterized marker of the hypothalamic-pituitary-adrenal axis immune interface status, was found to be modulated by the supplement. Conclusion: We discovered that the novel supplement was able to modify different antioxidant, metabolic and inflammatory pathways, improving the energy homeostasis and inflammatory status, and consequently alleviated hepatic steatosis.
