Nutriproteomics: A promising tool to link diet and diseases in nutritional research
2012
Ganesh, Vijayalakshmi | Hettiarachchy, Navam S.
Nutriproteomics is a nascent research arena, exploiting the dynamics of proteomic tools to characterize molecular and cellular changes in protein expression and function on a global level as well as judging the interaction of proteins with food nutrients. As nutrients are present in complex mixtures, the bioavailability and functions of each nutrient can be influenced by the presence of other nutrients/compounds and interactions. The first half of this review focuses on the techniques used as nutriproteomic tools for identification, quantification, characterization and analyses of proteins including, two-dimensional polyacrylamide electrophoresis, chromatography, mass spectrometry, microarray and other emerging technologies involving visual proteomics. The second half narrates the potential of nutriproteomics in medical and nutritional research for revolutionizing biomarker and drug development, nutraceutical discovery, biological process modeling, preclinical nutrition linking diet and diseases and structuring ways to a personalized nutrition. Though several challenges such as protein dynamics, analytical complexity, cost and resolution still exist, the scope of applying proteomics to nutrition is rapidly expanding and promising as more holistic strategies are emerging.
