Diverse '-omics' technologies permit the comprehensive quantitative profiling of a variety of biological molecules. Comparative '-omics' analyses, such as transcriptomics and proteomics, are powerful and useful tools for unraveling the molecular pathomechanisms of various diseases. As enhanced oxidative stress has been demonstrated in humans and mice with Down syndrome (DS), a redox proteomic analysis is useful for understanding how enhanced oxidative stress aggravates the state of individuals with oxidative stress-related disorders. In this review, '-omics' analyses in humans with DS and mouse models of DS are summarized, and the molecular dissection of this syndrome is discussed.
Keywords: Down syndrome; mouse models; proteomics; transcriptomics.
