Oncogenic reprogramming of tumor cell metabolism

The reprogramming of energy metabolism is emerging as an important molecular hallmark of cancer cells. Recent discoveries linking specific metabolic alterations to cancer development have strengthened the idea that altered metabolism is more than a side effect of malignant transformation, but may in fact be a functional driver of tumor growth and progression in some cancers. As a result, dysregulated metabolic pathways have become attractive targets for cancer therapeutics. We are applying MFA and cell-wide biochemical profiling to investigate the role of oncogenic proteins in regulating critical metabolic functions of tumor cells, and to identify metabolic pathways that can be inhibited to selectively impede tumor growth.
