- Novel Nutraceutical (silymarin, yeast & beta;-glucan, prebiotics, and minerals) shifts gut microbiota and restores large intestine histology of diet-induced metabolic syndrome mice(2023) NEHMI-FILHO, Victor; FREITAS, Jessica Alves de; FRANCO, Lucas Augusto Moyses; FONSECA, Joyce Vanessa da Silva; MARTINS, Roberta Cristina Ruedas; SANTAMARINA, Aline Boveto; MURATA, Gilson Masahiro; SABINO, Ester Cerdeira; SOUZA, Erica; FERREIRA, Matthew Thomas; OTOCH, Jose Pinhata; PESSOA, Ana Flavia MarcalGut dysbiosis contributes to chronic inflammation and oxidative stress associated with metabolic syndrome, and non-pharmacological, health-promoting supplements like nutraceuticals have been studied and used as a way to prevent or treat several illnesses. Thus, male C57BL/6 mice were divided into the following groups: control (CTL) _Vehicle and CTL_Nutraceutical; high-fat diet (HFD)_Vehicle, HFD_Nutraceutical, HFD_Nutraceutical_S, and isolated compounds. The vehicle and experimental formulations were administered by gavage once a day for four weeks with a high-fat diet simultaneously. In addition, we evaluated the composition of the fecal microbiota by partial 16S rRNA sequences directly amplified using a bacterial/archaeal primer set 515F/806R, and large intestine histomorphology was examined by H & E (Hematoxylin and Eosin), Masson's trichrome (MT), and PAS-AB (Periodic Acid Schiff-Alcian Blue) stains in these groups of mice. After four weeks of supplementation, only the Novel Nutraceutical supplement was able to increase & alpha; and & beta;-diversities, modulate the relative abundance in gut microbiota, decrease Firmicutes, and increase Bacteroidetes bacteria, meanwhile recovering the large intestine's (colon) histomorphology in CTL and HFD groups.
