MGMouse

Exploring the mechanisms of the effects of test products on the gut environment through mouse studies

What is MGMouse

MGMouse™ is a research and development support platform aimed at exploring the impact and mechanisms of test products on the gut microbiota through mouse experiments. It allows evaluation using not only regular mice but also mice colonized with human gut microbiota.

  • Evaluation system incorporated with our expertise in gut microbiota 
  • Integrated gut microbiota evaluation using the state-of-the-art technology “Metabologenomics®”
  • Evaluation using humanized mice with colonized human gut microbiota

Service Flow

Mouse Experiments

We conduct mouse studies on test products (products and materials). By using mice, we can also evaluate the effects on models that are similar to diseases and pathological conditions. Our researchers specializing in intestinal environment will propose the most appropriate study plan, such as designing a study using human intestinal bacteria-established mice or notobiotech mice. The basic measurement and analysis items are as follows

  • Gut microbiota metagenome(16S rRNA gene) data
  • Metabolome (metabolites)
  • Metadata such as body weight

Gut Environment Evaluation

We conduct comprehensive gut microbiota evaluations using our proprietary technology called “Metabologenomics®.” In addition to bacterial community analysis, which is commonly performed in gut microbiota evaluations, we also analyse the metabolites and metadata produced by gut bacteria. This approach contributes to understanding the mechanisms of how gut bacteria function and exert effects on the body when test products are ingested.

Research Results

We perform metagenomic and metabolomic analysis, as well as metadata analysis, on the results obtained. We estimate relevant factors and discuss the mechanisms through Metagen’s unique analysis. Based on the results and discussions, we support the publication of papers and propose the next steps, adding new evidence to support the effectiveness of the test products.

Measurement Items and Options

●Mouse Experiments

Oral glucose tolerance test (OGTT) /Treadmill test /Hair growth test, etc.

●Gut microbiome (metagenome) analysis

16S rRNA gene/shotgun

In addition to the above, we can also measure the presence of your desired gut microbiota using quantitative PCR.

●Gut Metabolites( metabolome) analysis

Determination and analysis of short-chain fatty acids (GC-MS) / bile acids (LC-MS) / comprehensive measurement and analysis (CE-TOFMS)

●Conference presentation and paper submission option

Upon request, we can coauthor conference presentations and paper submissions. This can be used to promote your company’s research and development capabilities, as a seed for evidence-based marketing, and to educate consumers.

Examples of implementation

When evaluating the effects of a single test product on mice gut microbiota:

Experimental Details

  • Test Mice: C57BL/6J strain
  • Groups and Sample Size: 2 groups (1 test material), n=5
  • Diet: Regular diet (Control) or diet mixed with the test material (Test)
  • Measurement Items: Food intake, body weight, water intake, (gut microbiota, metabolites)
  • Analysis Items: Profile analysis, variation analysis of gut microbiota and metabolites

Expected Results

For example, by using specific humanized mice, conducting gut microbiota analysis, metabolomics analysis, and analyzing metadata such as body weight and blood markers for mice raised on a regular diet versus mice administered the test material, Metagen performs its unique analysis. This allows for the estimation of relevant factors and discussion of mechanisms. Based on the results and discussions, we can contribute to enhancing efficacy of your product by adding evidence through additional experiments and paper publication.

Exmaples of Utilization

Research results obtained through this service are used for presentations at conferences and seminar events, sales activities at trade shows, and preliminary studies prior to conducting human clinical trials.
