| Project Title: | Fecal Transplant from Roux-Y-Gastric-Bypass rat model into a diet induced obesity rat model |
| Project Summary: | Investigating alterations in the intestinal microbiome metabolome and host blood metabolome in a diet induced obesity (DIO) rat model after fecal transplant from rats, which underwent Roux-Y-Gastric-Bypass surgery (RYGB). Experimental groups for rat experiments. 1)Rats in the ‘RYGB_Donor group’ underwent RYGB surgery. Postoperatively, animals received a two-choice diet, consisting of a SC and HFD. Once the animals recovered and achieved a stabilized weight reduction at 4 weeks postoperatively, body weight and food intake were recorded daily. 2)Rats allocated into the ‘RYGB_AB group’ were handled the same as animals in the ‘RYGB_donor group’. From postoperative week 4 onwards, animals received an antibiotic treatment (AB) consisting of ampicillin (1 g/l; Ratiopharm), vancomycin (0.5 g/l; Ratiopharm), neomycin (1 g/l; Bela-pharm), and metronidazole (1 g/l; CP-Pharma), provided freshly every day via drinking water.[19, 20] All antibiotics were given for the time period indicated in each figure.[21] 3)Rats in the ‘Lean group’ served as healthy, age-matched controls, constantly kept under SC. 4)Rats in the ‘Lean_AB group’ received the same antibiotic treatment as animals in the RYGB_AB group, serving as a control for antibiotic-specific side effects. All antibiotics were given for the time periods indicated in each figure. 5)Rats in the ‘DIO group’ received no surgery, but were otherwise handled like RYGB litter mates. 6)Rats in the ‘DIO_FMT_RYGB group’ received fecal RYGB_Donor microbiota transplantation once per week, but were otherwise handled like DIO litter mates. For fecal transplantation experiments, 100 mg of fresh stool from body weight-stabilized RYGB donors were re-suspended in 1 ml of PBS, homogenized carefully and administered via oral gavage with 200 μl of the suspension. 7)Rats in the ‘FMT_Lean group’ were handled like DIO litter mates, but were orally gavaged with 200 μl of filtrate received from lean donors, and served as a control for fecal transplantation and specificity of effect size(s) as a function of the donor microbiota. 8)Rats in the ‘DIO_PF_FMT group’ were handled like DIO litter mates, but pair-fed to the SC/HFD food intake of ‘FMT_Lean littermates, serving as a control for effects secondary to reduced caloric intake. |
