Cancer cells are always growing, and they need nutrients to keep up this fast growth. An exciting idea is that we might be able to starve cancer cells without harming healthy cells by getting rid of nutrients that cancer cells need. A drug being developed right now called ADI-PEG20 destroys a nutrient called arginine, which is an amino acid that is used to make protein and is particularly important for cancer cells. My lab studies what happens when cancer cells don’t have enough arginine. We want to understand how ADI-PEG20 works, how to improve it, and which cancers to treat with it. We have found that restricting arginine disrupts ribosomes, the machines that build new protein, causing them to get stuck and abandon their jobs early. We want to study three things to figure out how this impacts ADI-PEG20 treatment. First, why is protein production in cancer cells so sensitive to arginine levels? Next, what machinery in the cell is responsible for causing “starved” ribosomes to press the eject button in the middle of doing their jobs? Finally, what effect does this have on a cancer cell? This work will help us understand how a nutrient like arginine can directly control very important processes in the cell like protein production. It will also reveal how we can take advantage of cancer’s dependence on arginine to shrink tumors.

Multiple myeloma and AL amyloidosis are incurable cancers of blood cells. These blood cells are called plasma cells. There is only one therapy that is available for AL amyloidosis patients. In severe stages, AL amyloidosis patients survive less than one year. Amyloidosis plasma cells cause damage to the body by spilling in the blood a sticky protein. These sticky proteins attach to each other and build up in the heart. Buildup of proteins in the heart causes progressive poor function. AL amyloidosis is a major cause of malfunctioning of the heart and death. To cure AL amyloidosis, we need drugs that 1- stop plasma cells from spilling sticky proteins; 2- kill the cancer plasma cells; and 3-remove the buildup of sticky proteins from the heart. These drugs do not exist, because we do not know how sticky proteins get spilled and why the build-up is not removed.Recently, our lab found out how sticky proteins get out of amyloidosis plasma cells. We also showed that if we stop this process, cancer cells die. Finally, we discovered that cleaner cells that should remove sticky proteins from the heart are reduced and do not function in amyloidosis patients. Based on these data, we will make two novel drugs. One will stop spillage of sticky proteins and kill cancer cells. The other will remove sticky protein from the heart without the need of cleaner cells. Our work is doable and will create therapeutic options for AL amyloidosis patients that could cure their disease.

Every year, over 25,000 people need to have a stem cell transplant to treat their blood cancer. While this can cure their cancer, it also weakens the immune system. A weak immune system is a problem because it means people get more infections and can experience other complications like their cancer coming back. When we are healthy, our gut is filled with helpful bacteria. During cancer treatment, many patients lose these helpful bugs. Patients who lose the good bacteria after they have a transplant, don’t recover as well as patients who keep their helpful bugs. These good bacteria are needed for strong immune system recovery. We are working in the lab to find new ways to support healthy bugs during cancer treatment. We think this will help the patients’ immune system. Having a healthy immune system means fewer infections and a longer life. If successful, this research could lead to new treatments that help patients feel better during their transplant, avoid infections, and live longer. In the future, we will run clinical trials in transplant patients, which will lead to new standard treatments.

Ovarian cancer is hard to treat. Most patient’s cancer comes back after standard treatment. Once the disease is back it is more difficult to treat and patients will eventually die from it. Chemotherapy can also cause direct harm to the body. This can make patients delay treatment, stop it altogether, or lower their doses. It can also harm the good bacteria in the gut, which is important for how well treatments work. Our goal is to come up with new ways to predict, prevent, and manage these harmful effects. We also want to develop new therapies that can lead to complete and lasting responses, increasing chances of cure right from the start. To reach this goal we will use mathematical modeling. This will allow us to test many treatments quickly, which cannot be done with traditional laboratory methods. First, we will use patient blood samples to predict the risk of toxicity, helping doctors know when to change or pause treatment. Next, we will use math modeling to find the best combinations of new targeted therapies. Finally, we will reduce the harmful effects of chemotherapy on the gut using math modeling to improve how well those therapies work. This research could change how we treat cancer. It may lead to complete tumor response and better chances for a cure.

Pancreatic cancer is the third leading cause of cancer death in the United States. Treatments have changed very little in recent years. One challenge is that there are different “subtypes” of pancreatic cancer, so tailored therapies are desperately needed. Our lab found that drugs that block a protein called cyclin-dependent kinase 7 (CDK7) can kill the basal subtype, which is the most lethal. It makes up a quarter of pancreatic tumors and has the worst overall survival. We propose to study a drug that blocks CDK7 in patients with early-stage pancreatic cancer, after chemotherapy and before surgery. This funding will allow us to work with Carrick Therapeutics, who is giving us a supply of drug for the clinical trial. Our ultimate goal is to offer a new targeted treatment option and hope to pancreatic cancer patients.
