The Cryns lab focuses on understanding how tumors adapt to and survive metabolic stress caused by their rapid growth. These metabolic adaptions are unique to cancer cells and represent promising drug targets to selectively eradicate tumors. We are particularly interested in translating these insights into improved cancer biomarkers and therapies.
Specific projects include:
Regulation of metastasis by the cell stress protein αB-crystallin. We have identified αB-crystallin as a novel mediator of lung and brain metastasis in breast cancer that inhibits stress-induced apoptosis and promotes multiple steps in the metastatic cascade. We are actively investigating the mechanisms by which αB-crystallin promotes metastasis and developing strategies to therapeutically target this conserved stress response protein.
Metabolic priming tumors to targeted therapies. We have developed a new therapeutic paradigm that uses a diet deficient in the amino acid methionine to metabolically prime tumor cells to die by increasing tumor expression of a cell death receptor (TRAIL-R2). Methionine restriction also reduces fat and improves metabolic health in mice. We are currently exploring the mechanisms underlying these effects and translating these observations into clinical trials in breast cancer.
