Summary
Antibiotic resistance is one of our major challenges, with fears expressed that we may soon run out of effective antibiotics for the treatment of infections. The goal of this project is to develop a novel class of antibiotics that acts by enhancing our immune response to infection rather than attacking the bacteria themselves, and therefore will not be susceptible to the development of bacterial resistance. These agents inhibit the degradation of a key enzyme involved in combating infections.
A Novel Metabolic Role For UDP Glycosyltransferase 8 (UGT8)

Summary
The UDP glycosyltransferases (UGTs) are a family of enzymes that remove drugs and toxins from the human body as well as control levels of naturally produced molecules such as bile acids and hormones. We found that a new member of this family called UGT8 processes bile acids in the kidney and intestine and can affect how bile acids act to regulate metabolism. Our studies uncover new roles for bile acids in liver, kidney and gut health and in metabolic disorders such as diabetes and obesity.
Regulation Of Drug Detoxifying UDP Glucuronosyltransferases

Summary
Some organs in the body are particularly sensitive to fat-soluble chemicals taken in from the environment or present in food. They are also sensitive to hormones and other small molecule products of metabolism. Controlling the levels of these potentially toxic chemicals is essential in order to maintain the health of the organ. In this work we will investigate the regulation of detoxifying enzymes that protect these organs by inactivating and hastening the elimination of fat-soluble chemicals.
Characterization Of The Novel Drug And Xenobiotic Metabolizing UGT3A Enzyme Family

Summary
The elimination of chemicals made in the body or from environmental sources is essential for the maintenance of good health and the prevention of debilitating diseases. We have discovered two enzymes that use glucose and other sugars to detoxify fat-soluble chemicals. In this project we will study how these enzymes work and how they are regulated in the body. With this knowledge, we may be able to target the processes of drug and chemical detoxification to make them more efficient.
Investigating Novel Antibody Drug Conjugates For Treating Lung Cancer

Summary
Chemotherapy is first-line treatment for advanced lung cancer patients. Most patients inevitably develop chemotherapy resistance. To increase chemotherapy effectiveness, we are developing a new antibody-based approach to target cancer cells that die because of chemotherapy. The antibody is armed with a very potent drug released specifically at the cancer to cause death of surrounding, chemotherapy-resistant cells. Killing these cells may reduce rebound cancer growth and cause an immune reaction.
