Collection:
Collection ID: | CO002822 |
Collection Summary: | Two human stool donors were selected based on their inflammation profile which occurred prior to gut microbial community profiling. Female germ- free (GF) C57BL/6J mice, originally purchased from the Jackson Laboratory (Bar Harbor, ME) were housed and bred at the American Association for the Accreditation of Laboratory Animal Care-accredited Animal Resource Center at Montana State University. Mice were held in individually ventilated cages with sterile bedding before and after fecal transplantation from selected human stool donors. Two female mice received an inoculation with fecal material from a human donor categorized as having low or high systemic inflammation based on serum levels of six proinflammatory cytokines. Human donor stool slurry aliquots were administered to GF mice through oral gavage. Sexually mature male GF C57BL/6J mice were added to each cage approximately one week after transplantation. Male mice removed prior to birth of pups. Pups from the inoculated dams were co-housed by sex (3 – 5 mice/cage) with different microbial inoculations placed in separate isolators. Mice from each microbial inoculation were assigned to one of two juice groups: Aronia (ARO LO , = 3, ARO HI , n=5), or a sugar-matched juice (CON LO ,n=3, CON HI , n = 3). Weekly measurements of body weight and food and fluid intake were recorded. Blood samples were collected at the same interval into serum separating tubes. Whole blood was allowed to clot for 15 minutes before centrifugation at 1200 RPM for 15 minutes with resulting serum aliquoted and stored at -80ºC until analysis. After T8 sample collection, mice were euthanized via rapid CO 2 asphyxiation. |

Treatment:
Treatment ID: | TR002838 |
Treatment Summary: | At baseline (T0), regular drinking water was replaced with ARO or CON juice to begin a two-week familiarization period with the juice. ARO mice received an unpasteurized blend of Aronia juice, and CON mice received a sugar-matched beverage containing water, sorbitol, glucose, and fructose. The mice were housed in cages with free access to their respective juice. During the familiarization period, all mice received standard chow (LabDiet 5013). After the 2-week familiarization period (T2), mice began a 6-week high-fat diet, delivered ad libitum concomitant with juice consumption. The HFD (Teklad TD.96132) was chosen to induce obesity and present an inflammatory stimulus (Duan et al., 2018) . The HFD mimics a Western style diet and consisted of 40.6% fat, 40.7% carbohydrate, and 18.7% protein and was particularly rich in sugars and trans-fatty acids. All chow provided was sterilized via autoclaving or irradiation. A total of 150 mL of juice was provided per cage each week. Juice was refilled three times each week. |
