| Top: the schematic model of Wnt regulation of cancer metabolism and angiogenesis through the PDK1 enzyme, as deduced by the Irvine-led team. Bottom: staining of normal human small intestine (PDK1) and normal human colon shows correlations between high levels of Wnt signaling, PDK1 activity, and HIF1α levels.
