Metabolomics in Action: Enhancing Metabolic Diagnostics for Better Health

Kate Williamson, Editorial Team, European Hospital & Healthcare Management

Metabolomics is relatively a young but very actively growing scientific discipline which investigates metabolites in an effort to dissect the metabolic phenomena. Using small molecules, metabolomics improves disease diagnosis, tailors treatment to individual patient, and assists in drug discovery. This approach has the potential of enhancing the health status of individuals and redesigning the whole system of healthcare with the help of accurate metabolic profiling.

Introduction:

Metabolomics is an attractive and dynamically developing branch in the context of the modern world of sciences and medicine. It is on metabolomics which deals with the analysis of metabolites, which are the compounds that exist as a result of metabolism. Metabolomics is the study of small molecules in the body in order to determine the metabolic processes occurring in the body. This field is important in improving metabolic diagnoses and hence the improvement of the health of the people. Now it is time to introduce metabolomics, explain what it is, how it functions, and how it may enhance people’s well-being.

What is Metabolomics?

Metabolomics can be defined as the large scale study of metabolites present within a biological system. There are a variety of metabolites which exist in the blood, urine and tissues and are the final products of cellular activities. They give an entity of the ontogenetic condition of an organism whilst giving a detailed perception about its welfare and sickness.

Key Concepts in Metabolomics

  • Metabolome: The isolate total of metabolites of a biological sample.
  • Metabolism: The total of all the physical and chemical changes that take place in a cell or an organism.
  • Metabolic Pathways: A sequence of processes taking place in a cell through which different substances are either built up or dismantled.

How Does Metabolomics Work?

Sample collection process involves collection of biological samples from the tissue, cells or body fluid of an organism undergoing metabolism.

Sample Collection

The first thing that needs to be done is to obtain a biological specimen, which can be blood, urine, or a tissue sample. The type of sample collected depends on the kind of study that is being conducted. For example, blood test can give a general picture of the rate of metabolism in the whole organism, while tissue biopsy can give a picture of metabolism in a certain area of an organ.

Metabolite Extraction

After the samples have been procured, the metabolites are purified in several ways. This step usually requires a lot of caution because one aims at getting the metabolites in a form that can undergo further analysis without losing any properties they may possess.

Analytical Techniques

Several advanced analytical techniques are used to identify and quantify metabolites.

  • Mass Spectrometry (MS): The key to evaluating the mass-to-charge ratio of ions to look for and count the metabolites.
  • Nuclear Magnetic Resonance (NMR) Spectroscopy: Relies on the properties of the magnetic fields of atomic nucleons in order to identify the type and relative abundance of metabolites.
  • Chromatography: Directs the chromatographic separation of metabolites depending on their physical or chemical features.

Data Analysis

Analytical data acquired from the mentioned analytical techniques are voluminous and needs high end software for analysis. The molecular phenotype data is analyzed using bioinformatics tools to simply the biological analysis, to recognize the metabolites and map these to various pathways.

Applications of Metabolomics in Health

Metabolomics has a broad range of applications in health and disease. Here are some key areas where metabolomics is making a significant impact.

Disease Diagnosis and Prognosis

Compared to other omics, metabolomics can detect individual alterations of metabolites that are related to diseases, and hence the diagnostic capabilities it holds. For example:

  • Cancer: There are reagents that are given off in the blood or urine by carcinomas and these help in early diagnosis and follow up of the result of treatment being given.
  • Diabetes: Application of metabolic profiling to diabetes would reveal biomarkers that may be utilized for early diagnosis as well as efficient therapeutic approaches.

Personalized Medicine

The body metabolism is known to differ from one individual to another. Thus, through metabolomics, medical treatments can be prescribed according to the person’s metabolic profiles giving a shot at personalized medicine. This approach makes sure that particular treatments of disorders are effective as well as have less side effects.

Nutritional Science

Another point for metabolomics: it is possible to always evaluate the effect of diet on metabolism. Therefore, through studies of metabolic evolution to various diets, nutritionists are in a position to formulate efficient custom diets that enhance citizen wellbeing and minimize the rates of various diseases.

Drug Development

Contribution of metabolomics on drug development involves recognizing approaches to metabolism and toxicity of the drug. This in turn assist in the development of safer and better drugs in the market place.

Environmental Health

Lifestyle habits and also pollution and diet all play part in metabolism that was a general environmental aspect. Thus the metabolomics can analyze the effect of these factors on health and improve the policies in the environment and give out good advice for health.

Case Studies in Metabolomics

Case Study 1: Metabolomics in Cancer Research

In this work, metabolomics was employed to analyze the metabolic status of cancer patients. They came to realize that some of the metabolic values were unexpectedly high in cancer patients as compared to the normal people. These metabolites acted as markers of developing cancer and aided in the evaluation of the efficiency of cancer therapies.

Case Study 2: Metabolomics in Diabetes Management

In this context, this case study seeks to review the literature on the possible roles of metabolomics in the management of diabetes.

The given study focused on the patient with diabetes where certain metabolic alterations were found to be caused by the disease. Through research on these changes, a metabolomics-based diagnostic test was designed for an early diagnosis of diabetes. This test also enabled early intervention thus appropriate management of the disease.

Challenges in Metabolomics

While metabolomics holds great promise, it also faces several challenges. 

Complexity of Metabolomes

Consequently, human metabolome contains thousands of the different metabolites. The determination of all these metabolites and their amounts published is a big problem.

Standardization

Currently, the implementation of metabolomics methodologies is not uniform and there are differences among studies regarding the chosen methods.

Data Interpretation

Metabolomics can generate a huge amount of data and thus the interpretation of these data is done using bioinformatics tools and skills.

Future Directions

However, the future of metabolomics is rather promising setting all the above challenges into consideration. In the recent past, it has been getting more probable to analyze the metabolome mainly due to the development of new analytical principles which go together with progression in bioinformatics. Here are some future directions for metabolomics. 

Integrative Omics

Metabolomics integrated with other omics approaches offers a synergistic advantage as seen in genomics, proteomics and other related fields.

Clinical Applications

Continued development and improvements in omics technology will mean that metabolomics is bound to be incorporated as a standard application of clinical diagnostic tests in molecular medicine applications.

Technological Advancements

Single cell metabolomics and real-time metabolite monitoring are new technologies that will refine the understanding of metabolism and contribute to better health.

Conclusion:

It, therefore, clear that metabolomics plays a key role in the harnessing of metabolic diagnostics and the overall health. Thus, the analysis of small molecules in metabolism will provide important information about the molecular basis of diseases, individual approach to their treatment, and reveal new approaches to drug design.
