There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Title:
Lessons From Large-Scale Metabolic Phenotyping

Metabolomics is a growing discipline that allows the analysis of the thousands of structural different small molecules found within a biological system. These metabolites can be measured using a variety of different analytical approaches and we have developed gas chromatography mass spectrometry (GC-MS) and liquid chromatography mass spectrometry (LC-MS) for this purpose [1]. I shall provide an overview of metabolomics and lessons learnt from of our large-scale human serum metabolome project where we profiled 1200 healthy individuals [2]. Using these protocols we then went on to profile another ~1200 ageing individuals and identified key metabolic dysregulation which were drivers behind human frailty, which were validated in a further ~760 ageing individuals [3].
In parallel, we have been developing Raman and infrared microscopy in order to understand metabolic flux on a single cell level for bacterial community analysis. Recent insights in metabolic flux analysis will be highlighted.
