The studies in Dr. Anne Le's laboratory primarily focus on cancer metabolism and metabolic aspects of other diseases. Using metabolomics technologies, their studies have led to breakthrough discoveries revealing several characteristic features of the metabolism of cancer (PMID: 22225880). One of these, the dependence of cancer cells on glutamine metabolism, has translated into clinical trials as a novel therapy for cancer patients. They further tracked the metabolic pathways in the remaining tumor after this novel therapy and identified the best-suited drugs for combined synergistic therapy (PMID: 27559084). Recently, they uncovered a specific role of the neurotransmitter N-Acetyl-Aspartyl-Glutamate (NAAG) for the first time in cancer, suggesting the possible use of NAAG for tumor monitoring. Moreover, NAAG was identified as a glutamate reservoir in cancer (PMID: 30970252).

The Le laboratory consists of a diverse group of researchers led by Dr. Anne Le who is responsible for leading and directing projects. Every member of the lab is passionate about creating innovative solutions for improving the lives of cancer patients. The research conducted in Le lab exploits the altered cellular metabolism found in many cancers for prognostic and therapeutic potential.
The Le laboratory also provides metabolomics assessments to scientists and physicians, nationally and internationally.
- Provides consultation to basic, clinical, and translational research teams regarding the feasibility, design, and costs of projects using metabolomics technologies (including mass spec and NMR-based metabolomics);
- Provides metabolomics approaches based on specific research projects/questions: ranging from simple assays or targeted metabolomics to high-throughput approaches such as global metabolic profiling and stable isotope-13C, 15N-labeled on a wide variety of sample types;
- Provides extensive data analysis and suggests options for subsequent steps towards clinical implementation.
