Metabolism refers to chemical reactions that occur in the body that are indispensable for maintaining life. And, the term metabolome is a combination of “metabolite” and “ome”, which means “all” in Greek. Literally translated, it means “the whole of metabolites”.
For example, the process of eating rice and breaking it down into glucose to produce energy is one type of metabolic reaction. So, metabolites are substances produced in the process of this chemical reaction, and there are many types including sugars, amino acids, lipids, nucleic acids, and other compounds that function as signal transmitters. In other words, metabolome analysis means “analyzing all metabolites that have wide ranging compositions”.
By analyzing all metabolites, it is possible to understand and monitor changes in the metabolic system inside the body. Knowledge of metabolic changes is fundamental to understanding life phenomena, for example, biological mechanisms that cause diseases can be understood at the biomolecular level.
Importantly, metabolome analysis, which “analyzes all metabolites,” requires extremely advanced technology to comprehensively analyze each metabolite.
NOSTER has collaborated with Professor Makoto Arita of Keio University Faculty of Pharmaceutical Sciences—an internationally renowned expert in lipoquality (lipid quality) research using lipid metabolome analysis technology— to develop and established unique mass spectrometry technology that comprehensively measures diet-derived gut microbiota lipid metabolites, thereby enabling analysis of specific metabolites.
NOSTER’s metabolome analysis technology provides metabolome analysis of metabolites produced by gut microbiota
There are 1,000 species and more than 100 trillion gut microbes in the human digestive tract, and human hosts construct a complex and diverse microbial ecosystem inside themselves while exchanging metabolites produced by the gut.
In a collaboration with Professor Jun Ogawa of Kyoto University, NOSTER has discovered that gut microbiota have lipid metabolism pathways that differ from those of humans, and that dietary lipids produce unique lipid metabolites.
In addition, with the aim of establishing a new therapeutic base, we have built an original lipid metabolite library that utilizes the lipid metabolism of gut bacteria using our unique intestinal bacterial culture and synthesis technology.
Applying this NOSTER original lipid metabolite library, we provide a unique metabolome analysis in the still unknown world of gut microbiota metabolites.
NOSTER’s Gut Bacterial Lipid Metabolite Library
Wide range of areas related to lipids and microorganisms such as gut bacteria as described below.
Development of supplements and exploration of new functions of fats and oils and fermented foods
Analysis of metabolic mechanisms of gut bacteria
Elucidation of pathological mechanisms / Search and development of diagnostic markers/Evaluation of therapeutic effects
Studies related to gut microbiota and disease
NOSTER specializes in providing metabolome analysis for gut microbiota lipid metabolites using linoleic acid, α-linolenic acid, and γ-linolenic acid contained in dietary oil as substrates.
Relative quantitative values, metabolic pathway map, etc.
200,000 yen per sample (Depending on the number of samples). We also have special price options for academia. Please contact us for more information.
Intestinal flora analysis
If the requested sample is feces, in addition to 16s metagenomic analysis by the next-generation sequencer, hybrid flora analysis that individually quantifies the number of bacteria per fecal weight is also available.
NOSTER employs hybrid analysis of the gut microbiome that combines our unique in-house culture technology with gut microbe metagenomics analysis utilizing next-generation sequencing.
By combining the molecular biological approach to analyze the occupancy rate of each gut microbe with next-generation sequencing and our unique technology to culture anaerobic bacteria (Akkermansia, Bacteroides, Bifidobacterium, Blautia, Clostridium etc.) it is now possible to quantitively analyze the cell count per weight of feces. Notably, this hybrid, qualitative and quantitative analysis enables a much more detailed understanding of the microbiome that could not be achieved by existing metagenomic analysis alone.
