“The Effects of Tetraploidy on Sphingolipid Metabolism and Chemosensitivity in C. elegans”

Cancer treatments such as chemotherapy and radiation are effective for destroying most cells within a tumor, but in many cases, a small number of resistant cells remain. Those resistant cells have unique properties: they are initially non-dividing, stress-resistant, giant cells that have extra copies of their genomes (called polyploidy).

When they eventually do divide, the recurring cancer is often more aggressive than the initial tumor. To better understand how those stress-resistant cells work, we are using roundworms called Caenorhabditis elegans that, when stressed, form larger animals that are stress-resistant and also carry extra copies of their genomes. Using innovative tools available to study these worms, we hope to find new ways to identify and target resistant polyploid cancer cells and improve cancer treatments.

“Defining the Role of Overexpressed PI3K Isoforms in Compensating for the Atypical KRASG12R Mutation in Pancreas Cancer”

Pancreatic cancer will become the 2nd most deadly cancer in the U.S. by 2030. Pancreatic cancer is defined by the presence of a KRAS mutation, which is mutated in 95% of pancreatic cancer patients. Of these, nearly 20% have the KRASG12R mutation. KRASG12R uniquely fails to regulate several metabolic programs previously assigned to mutant KRAS function. I have shown that KRASG12R cannot activate PI3Kα. Further, I showed that multiple PI3K isoforms are overexpressed in pancreas cancer.

This proposal seeks to define the role of the many PI3K isoforms in the pancreas. In addition, I have observed that KRASG12R cell lines are sensitive to the loss of the RALA and RALB small GTPases. RAL GTPases have been understudied in pancreatic cancer. Therefore, RAL signaling, in the context of KRASG12R, will be determined. This proposal uses KRASG12R to define the role of KRAS in the promoting of pancreas cancer. My research has shown that all KRAS mutations are not created equal. This proposal seeks to expand on that observation by defining KRASG12R-specific signaling. Data from these studies will be used to develop new targeted therapies for pancreatic cancer.

“CDK6 in T Cell Leukemia Infiltration”

An enzyme known as phosphofructokinase, platelet (or PFKP), which plays an important role in breaking down glucose to create energy, is important in clinical cancer research because its cellular expression level is associated with decreased survival rates in cancer patients. Preliminary data and analyses from Dr. Wang’s lab suggest that PFKP moves into the nucleus, which is the part of a cancer cell that contains its genes and controls its growth and production, to regulate leukemia, allowing it to spread throughout multiple organs and preventing the body’s immune system from recognizing and killing the cancer cells.

In this study, Dr. Wang’s lab will test how preventing the movement of PFKP into the nucleus affects the treatment of leukemia outside of humans. The study will also look at whether PFKP that is found in the nucleus can help predict whether a patient may develop an aggressive form of T cell leukemia.
