The role of oncogenes in regulating necroptosis and the significance of necroptosis potential in cancer was not known. Using high-throughput screening, bioinformatics, and methods in cell and molecular biology, I found that escape from necroptosis is an oncogene-driven, pan-cancer, and prevalent phenomenon, suggesting that escape from necroptosis could be a hallmark of cancer. I identified oncogenic BRAF and AXL mutations as major drivers of this escape. Using molecular biology and biochemical methods, as well as mouse models of systemic inflammation, I found that necroptosis, surprisingly, requires the activity of the anti-inflammatory TAM kinases. Finally, I discovered that the initiator of necroptosis, RIPK1, mediates the sensing cytosolic glucose levels by the AMPK-mTORC1 pathway to regulate lysosomal homeostasis and cell response to energetic stress.

The role of mTOR in activation of Akt was not defined and the inability of PDK1 inhibitors to block tumor growth was not understood. I characterized the first specific PDK1 inhibitor and found that unlike other kinases activated by PDK1, Akt retains activity upon inhibition of PDK1 due to its ability to co-localize with PDK1 at the plasma membrane. This finding explained why targeting PDK1 fails to inhibit tumor growth. I also discovered that Akt activation by PDK1 depends on Akt phosphorylation by mTOR. This discovery revised the model of Akt activation and provided a novel therapeutic strategy for increasing the efficacy of PDK1 inhibitors at blocking tumor growth: by co-targeting PDK1 and mTOR, Akt activity can be fully blocked, leading to a potent inhibition of cancer cell growth.

I identified and contributed to the identification of novel transcriptional targets of the Wnt/β-catenin signaling pathway (MENA, BRI, and HSF2) and demonstration that MENA is a novel putative tumor-suppressor gene.
