Insights from multi-omics integration in complex disease primary tissues.

Area of Science:

• Genomics
• Systems Biology
• Complex Disease Research

Background:

• Genome-wide association studies (GWAS) have identified genetic links to complex diseases.
• Understanding the molecular mechanisms underlying these diseases requires further investigation.

Purpose of the Study:

• To highlight progress in integrative multi-omics approaches for studying complex diseases.
• To emphasize the importance of high-resolution omics techniques and population diversity.

Main Methods:

• Integrative multi-omics analyses.
• Review of recent studies on type 2 diabetes (T2D), osteoarthritis, Alzheimer's disease (AD), and systemic lupus erythematosus (SLE).
• Discussion of single-cell and spatial omics methodologies.

Main Results:

• Integrative studies are advancing the understanding of complex disease development.
• High-resolution omics techniques offer deeper mechanistic insights.
• Current research often overlooks understudied cell types and population diversity.

Conclusions:

• Integrative multi-omics approaches are crucial for elucidating complex disease mechanisms.
• Future research must incorporate diverse populations and understudied cell types.
• Advanced techniques like single-cell and spatial omics will be vital for future discoveries.
