Metabolic Phenotyping Core

The goal of the Metabolic Phenotyping Core is to provide users with access to high-quality model creation and detailed metabolic phenotyping.

 

Human based nutrition and obesity research studies are generating data at an unparalleled pace. These data permit investigators to generate many disease-related hypotheses; however the sophisticated infrastructure needed to create disease-relevant models and the detailed metabolic technologies necessary to test these hypotheses lie outside the expertise of many individual research groups. Core Director Alex Soukas’s recent work in Cell, describing two metformin response elements, conserved from worms to humans, through which metformin inhibits cancer growth and prolongs lifespan exemplifies the type of translational work supported by this Core.
