Dudley W. Lamming, Ph.D.
Lab: C4141 VA Hospital (4th floor - C wing)
The Lamming laboratory is primarily focused on understanding the physiological role played by the mechanistic target of rapamycin (mTOR), a protein kinase that, through a diverse set of substrates, regulates cellular processes including growth, metabolism, and aging. Recent work has shown that rapamycin, an inhibitor of mTOR signaling, can promote health and longevity in model organisms including mammals. As detailed by Dr. Lamming in a recent JCI review - Rapalogs and mTOR inhibitors as anti-aging therapeutics - understanding and manipulating the mTOR signaling pathway may provide insight into the treatment of age-related diseases, including diabetes, Alzheimer's disease, and cancer.
Specific questions of the laboratory include:
- Understanding the physiological role played by mTOR complex 2 (mTORC2) using mouse models;
- Identification of compounds that can selectively regulate either mTORC1 or mTORC2 as possible therapies for age-related diseases and type 2 diabetes;
- Identifying the mechanisms underlying the metabolic consequences of aging.
