In this work, we evaluate the initial feasibility of
detecting elevated aerobic glycolysis in a spontaneous
transgenic mouse model of thymic lymphoma, which is
challenging due to the close proximity of the thymus to
the heart, where high levels of pyruvate and its
metabolites could confound data analysis. Dynamic MRS
using hyperpolarized [1-
13
C] pyruvate was
performed on p53-/- mice at various stages of disease
progression. High correlation between tumor volume and
normalized lactate confirms that hyperpolarized
measurements are indeed modulated by tumor metabolism,
establishing the initial feasibility for metabolic
investigations in a spontaneous transgenic model of
lymphoma.
