Although FT-A created a significant upsurge in bacterial richness/diversity, FMT did not significantly improve gut microbiota composition compared to the CR at phyla and bacteria genera levels, and only significant raises in and genera were observed. These results could suggest that additional mechanisms different from bacterial microbiota engraftment participates in these beneficial effects. Therefore, FT-A represents a very positive synergetic approach for obese individuals that do not respond well to moderate restrictive diet programs. infection19C22. However, the potential usage of FMT in additional microbiota-associated conditions different from such as inflammatory bowel disease, metabolic syndrome or obesity is still under investigation23C27. Fecal microbiota transplantation has also logistical difficulties such as FMT standardization, including donor selection, FMT material preparation and administration routes along with appropriate rules28,29. With this context, autologous transplant or autotransplant (transplantation of the Etomoxir pontent inhibitor individuals personal feces before developing the disease) emerges like a well-tolerated, safe and more appropriate approach from an honest perspective. In fact, autotransplant theoretically has a more desirable security profile than heterologous fecal transplants because the feces come from the same patient in a healthy state and, consequently, will minimize the risk of exposure to potentially pathogenic microorganisms not previously experienced by the patient. With the premise of improving obesity and its connected disorders, we have investigated if fecal transplantation, heterologous and autologous, potentiates the effects of a moderate caloric restriction (CR) on body weight gain and adiposity in obese mice. For the autologous transplantation, each animal received their personal faeces but collected before these mice developed obesity. To our knowledge, there is no encounter in this regard. Results Effects of fecal transplantation Etomoxir pontent inhibitor (heterologous and autologous) on body weight, feed effectiveness, adipose cells and liver excess weight The increased body weight gain induced by a HFD (p? ?0.0001 Control; #HFD, CR, $FT-H. Effects of Fecal Transplantation (Heterologous and Autologous) on glucose rate of metabolism, triglyceride (TG) serum levels and bacterial translocation As observed in Table?1, the ingestion of a HFD for 18 weeks induced a significant increase in glucose and insulin serum levels as well as with the insulin resistance index, the HOMA index, compared to the control animals (p? ?0.05). A moderate CR diet for 6 weeks did not result in significant improvements in these guidelines. However, FT-mice (both Etomoxir pontent inhibitor heterologous and autologous FT-mice) showed a significant decrease in all guidelines (p? ?0.05 Control; #HFD, CR, $$FT-H. Fecal Transplantation (Heterologous and Autologous) raises fatty acid oxidation in liver Although no significant variations were observed in the mRNA levels of PPAR, ACOX Mouse monoclonal to IgG1 Isotype Control.This can be used as a mouse IgG1 isotype control in flow cytometry and other applications or CPT1 in adipose cells due to the fecal transplantations (data not showed), a significant increase was observed in the hepatic manifestation of all of these genes in the FT-A group compared to the HFD animals (Fig.?3). Six weeks under a moderate caloric restriction and the heterologous fecal transplantation were also accompanied by significant raises in the mRNA levels Etomoxir pontent inhibitor of ACOX, CPT1 and PPAR in liver, however, the induction of these beta-oxidation genes was more potent in those animals treated with autologous fecal transplants (p? ?0.001 Control; #HFD and $FT-H. Effects of Fecal Transplantation (Heterologous and Autologous) on bacterial diversity/richness Two indexes of bacterial richness Etomoxir pontent inhibitor (Observed varieties and Chao-1) and one of dominance (Simpson index) have been evaluated. At the end of the experimental period, a significant decrease in bacterial richness was observed after the ingestion of a HFD. This was not counteracted by 6 weeks on CR (Fig.?4). A inclination to improve such decrease was observed in the FT-A group, becoming especially significant with the Observed.
