Type 2 diabetes mellitus (T2D) is rising globally. Metabolomics and proteomics offer insights into T2D biomarkers and pathways, aiding early detection and understanding of this complex metabolic disease.
Area of Science:
- Biochemistry
- Genomics
- Proteomics
Background:
- Rising global burden of type 2 diabetes mellitus (T2D) and its complications like cardiovascular disease.
- Need for understanding metabolic disturbances underlying T2D pathogenesis.
- Emergence of high-throughput metabolomics and proteomics for biomarker discovery.
Purpose of the Study:
- To provide an overview of circulating metabolomics and proteomics findings in large human population studies related to T2D.
- To highlight the potential of these 'omics' fields in T2D screening, diagnosis, and prognosis.
- To discuss the integration of multiomics strategies for deciphering causal associations in T2D.
Main Methods:
- Utilizing high-throughput technologies for metabolomics and proteomics analysis.
- Analyzing circulating biomarkers in large human population studies.
- Integrating metabolomics, proteomics, and genomics data (multiomics).
Main Results:
- Identification of circulating biomarkers for T2D, detectable over a decade before clinical diagnosis.
- Metabolite and protein markers provide insights into metabolic pathways involved in T2D development.
- Multiomics approaches offer a powerful analytical method for causal association studies.
Conclusions:
- Metabolomics and proteomics are powerful tools for advancing T2D research.
- Circulating biomarkers show promise for early T2D screening, diagnosis, and prognosis.
- Careful study design and sample handling are crucial for the effective application of these 'omics' technologies in T2D research.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
