Lactate Dehydrogenase expression and activity is up-regulated in various malignancies, including prostate cancer. In a recently developed transgenic mouse model, in which the LDH-A gene is deleted selectively in a temporal fashion, hyperpolarized 13C frequency specific MRI method was used to monitor early changes in LDH-A expression within prostate tumor tissue.
