Overweight & Obesity

The metabolome: A way to measure obesity and health beyond BMI

The link between obesity and health problems may seem apparent. People who are obese are at higher risk of type 2 diabetes, liver disease, cancer, and heart disease. But increasingly, researchers are learning that the connection ...

New powerful tool measures metabolites in living cells

By engineering cells to express a modified RNA called "Spinach," researchers have imaged small-molecule metabolites in living cells and observed how their levels change over time. Metabolites are the products of individual ...

Metabolomics

Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles. The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes. Thus, while mRNA gene expression data and proteomic analyses do not tell the whole story of what might be happening in a cell, metabolic profiling can give an instantaneous snapshot of the physiology of that cell. One of the challenges of systems biology and functional genomics is to integrate proteomic, transcriptomic, and metabolomic information to give a more complete picture of living organisms.
