Study TitleThe investigation of the role of dietary inulin in NASH progression with mouse fecal metabolites
Study Typenon-targeted LC-Mass analysis
Study SummaryTo investigate the role of dietary fiber in non-alcoholic steatohepatitis (NASH) progression, male C57 mice was randomly assigned into four groups that received normal chow diet (NCD), choline deficient high fat diet (CDHFD), CDHFD + 10% inulin (CDHFD-I), CDHFD + 10% Cellulose (CDHFD-C). Additionally, some mice received inulin or cellulose was treated with 13C labelled fiber for 36 hours. Fecal metabolites were analyzed by non-targeted metabolomics.Results shown that the fecal metabolites from Inulin treatment group signficantly distinguished from that from CDHFD only group, while only negligible alterations was induced by cellulose treatment, indicating that inulin not cellulose could be well fermented by gut microbiota. The 13C tracing results shown that nineteen 13C-inulin labelled metabolites were also captured including pantothenate, phosphoethanolamine and adenosine. These metabolites are reported to play a protective role in reducing fat accumulation and ameliorating cellular oxidative stress and inflammation, indicating that the mechanism inulin suppresses NASH may through mediating modulating gut metabolites.

Treatment:

Treatment ID:TR002626
Treatment Summary:Male C57 mice was randomly assigned into 4 groups that received Normal chow diet (NCD), Choline deficient high fat diet (CDHFD), CDHFD + 10% inulin (CDHFD-I), CDHFD + 10% Cellulose (CDHFD-C). Among the mice received inulin or cellulose, some of them received 13C labelled inulin or cellulose for 36 hours. Mouse stool were collected.

Sample Preparation:

Sampleprep ID:SP002620
Sampleprep Summary:25 mg of sample was weighted to an EP tube, and 500 μL extract solution (acetonitrile: methanol: water = 2: 2: 1) containing internal standard (L-2-Chlorophenylalanine, 4 μg/mL) was added. After 30 s vortex, the samples were homogenized at 35 Hz for 4 min and sonicated for 5 min in ice-water bath. The homogenization and sonication cycle was repeated for 2 times. Then the samples were incubated at -40 ℃ for 1 h and centrifuged at 12000 rpm for 15 min at 4 ℃. 400 μL of supernatant was transferred to a fresh tube and dried in a vacuum concentrator at 37 ℃. Then, the dried samples were reconstituted in 200 μL of 50% acetonitrile by sonication on ice for 10 min. The constitution was then centrifuged at 13000 rpm for 15 min at 4 ℃, and 75 μL of supernatant was transferred to a fresh glass vial for LC/MS analysis. The quality control (QC) sample was prepared by mixing an equal aliquot of the supernatants from all of the samples.

Chromatography ID:CH003066
Chromatography Summary:Non-targeted metabolomic analysis was performed on a 1290 Infinity series UHPLC System (Agilent Technologies) coupled to a Triple TOF 6600 mass spectrometer (AB Sciex ) equipped with an electrospray ionization (ESI) source by Biotree company (Shanghai, China). Briefly, chromatographic separation was achieved by using a Waters BEH Amide column (2.1 * 100 mm, 1.7 µm) under 25 ℃. The mobile phase consisted of water with 25mM ammonium acetate and 25 mM ammonium hydroxide (A) and acetonitrile (B). The flow rate was 0.5 ml/min.
