The invisible universe within us holds keys to diagnosing and treating diseases with unprecedented precision
Imagine if a single drop of blood could reveal not just whether you're sick, but what specific disease you have, how it's likely to progress, and which treatment would work best. This isn't science fiction—it's the promise of metabolomics, a revolutionary scientific field that studies the complete set of small-molecule chemicals found within our bodies.
These molecules, known as metabolites, serve as real-time snapshots of our health, aging, and disease processes. While this science has been transforming medical research globally, a dedicated community of Russian scientists has been making remarkable contributions, often unnoticed by the wider world.
Over the past decade, Russian researchers have pioneered innovative approaches that are pushing the boundaries of how we understand and diagnose diseases ranging from cancer to Parkinson's.
Metabolomics represents the youngest member of the "-omics" sciences triad, joining the more established fields of genomics (which studies genes) and proteomics (which focuses on proteins).
Shows the blueprint of a house - the genetic instructions for building and maintaining an organism.
Reveals the walls and furniture - the proteins that carry out most cellular functions.
Tells you what's actually happening inside - the metabolic activities and responses.
The term "metabolome" was first introduced in 1998, but the field truly gained momentum after 2010, largely driven by advances in high-performance analytical methods and sophisticated data processing techniques . Metabolites are the substrates and products of virtually all biochemical reactions in our bodies. They play crucial roles in energy generation, cellular signaling, and carry invaluable information about our physiological state and any pathological processes that might be underway .
Metabolomics is the latest trend in the "-omics" sciences, of which technologies are widely used today in all life sciences.
Russia's systematic venture into metabolomics began at the Institute of Biomedical Chemistry (IBMC) in Moscow under the leadership of Academician Alexander I. Archakov .
Russia's first Department of Proteomic Research was established at IBMC .
The "Human Proteome" Core Facility was created at IBMC , embracing the concept of systems biology.
Establishment of Russia's first dedicated metabolomics laboratory—the "Laboratory of Mass Spectrometry Metabolomic Diagnostics" under Dr. Petr G. Lokhov .
The Mass Spectrometric Research Center was established at the International Tomography Center in Novosibirsk, under Dr. Yuri P. Tsentalovich .
| Institution | Location | Key Research Focus |
|---|---|---|
| Institute of Biomedical Chemistry (IBMC) | Moscow | Metabolomic diagnostics, disease biomarkers, aging |
| International Tomography Center, Siberian Branch of RAS | Novosibirsk | Ophthalmic diseases, cataract pathogenesis |
| Tomsk State University with Siberian State Medical University | Tomsk | Host response to infections, helminth infections |
| Saint Petersburg State University with partner institutes | Saint Petersburg | Plant metabolomics, potato research |
| Endocrinology Research Center | Moscow | Metabolic disorders, diabetes |
One of the most impressive achievements of Russian metabolomics emerged from research on prostate cancer diagnosis—a disease affecting millions of men worldwide. The standard screening test (PSA test) often produces false positives and unnecessary biopsies, creating an urgent need for more accurate diagnostics.
Blood plasma samples from prostate cancer patients and healthy volunteers
Isolation of low-molecular-weight fraction containing metabolites
Direct infusion mass spectrometry (DIMS) to identify and quantify metabolites
Statistical methods to identify patterns distinguishing cancer patients
The results were striking. The metabolomic approach achieved 95% sensitivity (correctly identifying cancer patients) and 96.7% specificity (correctly identifying healthy individuals), significantly outperforming the traditional PSA test which showed only 35% sensitivity and 83.3% specificity on the same samples .

| Sensitivity | 95% | 35% |
| Specificity | 96.7% | 83.3% |
| Overall Accuracy | 95.7% | 51.7% |
| Area Under ROC Curve (AUC) | 0.994 | 0.59 |
Further analysis identified six specific metabolites that were distinctive in prostate cancer patients. Two particularly promising biomarkers were acylcarnitine (AUC: 0.97) and arachidonoylamine (AUC: 0.86), both significantly outperforming the PSA test . These discoveries open possibilities for not just better diagnosis but understanding the underlying metabolic disruptions in cancer.
Metabolomics research relies on sophisticated technology and methodological approaches. Russian laboratories have developed particular expertise in several key areas:
| Tool/Method | Function | Application Example |
|---|---|---|
| Mass Spectrometry | Identifies and quantifies metabolites based on mass and charge | Disease biomarker discovery |
| Direct Infusion Mass Spectrometry (DIMS) | Direct analysis without prior separation, enabling high-throughput screening | Metabolic fingerprinting for cancer diagnosis |
| "Dried Blood Spot" Method | Allows blood collection outside laboratory settings using minimal blood volume | Home-based sampling for clinical studies |
| Metabolic Fingerprinting | Simultaneous analysis of thousands of metabolites in a single sample | Creating disease-specific metabolic signatures |
| Statistical Pattern Recognition | Identifies significant differences in metabolite patterns between patient groups | Distinguishing cancer patients from healthy individuals |
The applications of metabolomics in Russia extend far beyond cancer diagnostics, spanning multiple scientific disciplines:
Researchers at the Novosibirsk laboratory focus on biochemical changes in eye tissues associated with cataract formation and other age-related conditions . Their work aims to develop new approaches for prevention and treatment of these common vision-impairing conditions.
Collaborative efforts between the IBMC, Institute of Developmental Biology, and Kazan State Medical University have explored Parkinson's disease through metabolic profiling, seeking early detection methods for this neurodegenerative disorder .
Scientists at the Endocrinology Research Center in Moscow have investigated metabolic changes associated with impaired glucose tolerance, potentially leading to earlier detection of diabetes risk . Other groups have studied obesity-related metabolic shifts .
A different application of metabolomics emerges from St. Petersburg, where researchers study potato metabolism . They're developing methods to identify potato varieties resistant to adverse environmental conditions, contributing to food security through scientific phenotyping.
Russian metabolomics has journeyed from a nascent field to a robust scientific discipline with remarkable achievements in just over a decade. The work of dedicated research teams across Moscow, Novosibirsk, Tomsk, St. Petersburg, and other cities has demonstrated that the complex language of metabolites can be translated into real-world solutions for human health and agriculture.
What makes this science particularly compelling is its potential accessibility—future diagnostic tests might require no more than 10 microliters of blood (about one-fifth the volume of a single drop), and samples could potentially be collected at home using the "dried blood spot" method .
As metabolomics continues to evolve, we move closer to a future where medicine becomes increasingly personalized, predictive, and precise—all thanks to scientists learning to listen to the whispers of molecules within us.
