Pros and cons of metabolomic sequencing

Metabolomic sequencing, as a cutting-edge technology in the field of life science research, has shown great potential in recent years in revealing the metabolic status of organisms, exploring disease mechanisms, and guiding personalized treatments. It systematically detects and identifys metabolites in biological samples through high-throughput analytical methods, providing us with a completely new perspective to examine the complexity and diversity of life activities. However, like any emerging technology, metabolomic sequencing comes with its unique advantages and challenges.

Metabolomics Sequencing

1. Advantages of metabolomic sequencing1. Easier to detect: Small changes in gene and protein expression will amplify the metabolites, making these changes more easily detected by metabolomic sequencing. 2. Simple technology: Compared with genomics and proteomics, metabolomic sequencing does not require the establishment of a database of whole genome sequencing and a large number of expression sequence tags, and the analysis methods are simpler. 3. Few metabolic species: There are much fewer species than the number of genes and proteins, which makes it easier to confirm and follow-up analysis of metabolites. 4. Strong versatility: Metabolites are similar in various biological systems, so the technology used in metabolomic sequencing is more general and is suitable for the research of multiple biological systems. 5. Widely used: Metabolomic sequencing has been widely used in basic physiology, biochemistry, drug toxicity tests, functional genome, clinical diagnosis, clinical treatment and efficacy evaluation, nutrition, drug metabolism and molecular epidemiology.

2. Disadvantages of metabolomic sequencing1. Complex data processing: Metabolomic sequencing produces a large amount of data, and it takes a lot of time and energy to process these data, which has high requirements for the ability and experience of technicians. 2. Data repeatability and stability issues: Due to the influence of multiple factors, metabolomic data may vary greatly between different laboratories, which limits its reliability and accuracy in clinical applications. 3. Unable to analyze the interaction between specific molecules: Metabolomic sequencing can only reflect the overall state of intracellular metabolism, and in-depth analysis of the interaction relationship between specific molecules has certain limitations on the mechanism of disease occurrence and the determination of therapeutic targets. 4. Standardization problem: In terms of sample collection, quality control, data analysis, etc., the standardization of metabolomic sequencing needs to be further improved to improve the credibility and comparability of the data. 5. High noise and high-dimensional problems: organisms contain a large number of endogenous small molecules that maintain the physiological functions and functions of the body, and biomarkers with specific research significance are only a small part of them. In the context of holistic metabolites, a small number of functional metabolites are susceptible to noise interference from useless metabolites. At the same time, the number of metabolites detected by the non-targeted metabolites is much larger than the number of samples, and processing these data requires the use of complex statistical analysis methods.

Metabolomic sequencing has the advantages of easy detection, simple technology, few metabolic species, strong versatility and wide application. However, it also has the disadvantages of complex data processing, data repeatability and stability issues, the inability to analyze specific intermolecular interactions, standardization issues, and high noise and high dimensions.
