Proteomic signatures detectable in children may predict an increased risk for cardiovascular-kidney-metabolic disease (CKMD) in later life, offering a potential precision prevention approach to address cardiometabolic diseases at the earliest opportunity.

About Proteome

• A proteome is a set of proteins produced in an organism, system, or biological context. 
• We may refer to, for instance, the proteome of a species (for example, Homo sapiens) or an organ (for example, the liver). 
• The proteome is not constant; it differs from cell to cell and changes over time. 
• The proteome of any given individual will be unique, as protein expression patterns are determined by an individual’s genes.
• The proteome is always significantly larger than the number of genes in an individual due to a number of factors:
  • Gene sequences may be alternatively spliced following transcription to generate multiple protein variants from a single gene.
  • Proteins may be modified (e.g. glycosylated, phosphorylated, etc.) following translation to promote further variations.
• Proteomics is the large-scale study of proteomes. 
• With each protein playing distinct roles and functions, proteomics provides valuable insights into cellular processes, signaling pathways, and disease mechanisms. 
• Scientists typically study the proteome using techniques like mass spectrometry or traditional protein sequencing.
• Proteomics is used to investigate:
  • when and where proteins are expressed
  • rates of protein production, degradation, and steady-state abundance
  • how proteins are modified (for example, post-translational modifications (PTMs) such as phosphorylation)
  • the movement of proteins between subcellular compartments
  • the involvement of proteins in metabolic pathways
  • how proteins interact with one another
• Understanding the proteome can shed light on disease mechanisms, help identify potential drug targets, and develop novel therapeutic interventions.
