Research in the Tamae Lab applies the principles and tools of biochemistry, analytical chemistry, molecular biology and develop novel quantitative methods, when needed, to address the molecular mechanisms of disease.  Dr. Tamae's primary research interests are guided by a desire to understand the metabolic milieu of the cell and interrogate the intersection of cellular metabolism and cancer using bioanalytical techniques such as liquid chromatography tandem mass spectrometry.  His broader interests include understanding adaptive mechanisms that cancer cells employ to become resistant to treatment.

Cancer Biology and Metabolism

1. Glucose metabolism: Breast, lung and colon cancer, among others, have been shown to metabolize large amounts of glucose relative to normal tissue.  This hallmark has come to be known as the Warburg effect.  This phenotype is used in the clinic to image tumors using 18F-deoxyglucose positron emission tomography.  The Tamae lab is investigating the variety of molecular mechanisms that these cancer cells utilize to adapt to endogenous toxic by-products that are generated by such high levels of glucose metabolism.  The ultimate goal is to gain therapeutic insight from these studies.

2. Hormone metabolism: Breast and prostate cancer are the most frequently diagnosed cancers in the developed world.  Both cancers are hormone-driven.  Hormone biosynthesis and signaling are thus a rich area for therapeutic targeting and form a cornerstone in treatment.  These therapies are effective and increase survival in many patients, but a subset of patients have tumors display resistance and fail to respond to available therapies.  Triple negative breast cancer and castration-resistant prostate cancer are two such examples of difficult to treat subsets that have poor patient prognosis.  The Tamae lab is interrogating hormone metabolism and compensatory mechanisms in response to therapy in appropriate model systems.

3. Metabolic syndrome and cancer risk: The metabolic syndrome encompasses obesity and diabetes, both of which are a growing burden on healthcare systems world-wide.  While the primary risk associated with the metabolic syndrome is cardiovascular disease, a growing body of research suggests that the hyperlipidemia and hyperglycemia may also increase one's relative risk for certain cancers.  Separate epidemiological data also indicates that the affordable and regularly prescribed anti-diabetic drug, metformin reduces one's relative risk for certain cancers.  Teasing out the underlying mechanisms between the metabolic syndrome and cancer is interesting as there may be multiple layers of cross-talk between a variety of signaling and metabolic pathways such as that of glucose and hormone metabolism.
