DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Comprehensive multi-omics approach reveals detailed insights into diabetes mechanisms

In a recent study published in Nature Communications, researchers utilized a comprehensive multi-omics approach, integrating genomic, proteomic, and metabolomic data from a diverse cohort, to uncover detailed molecular interactions and identify distinct diabetes subgroups.
