Focus

This program focuses on developing metabolomic applications (MRS, MRI, LC-MS and optical methods) to diagnose cancer.

We have recently defined the detailed mechanism of action of lonidamine (LND). This antineoplastic agent selectively acidifies tumors and decreases their bioenergetic status. The mechanism includes:

Inhibition of the mitochondrial pyruvate carrier (MPC)
Inhibition of monocarboxylic acid transporters (MCT1 and MCT4)
Inhibition of complex II at the ubiquitin dehydrogenase step, and inhibition of flux through the pentose shunt that decreases glutathione production and increases production of reactive oxygen species thereby enhancing tumor radiosensitivity
