Research: Next-generation therapies for diseases of aging
Research Interests / Laboratory Techniques
As we age, the biomolecules within each of our cells, including DNA, proteins, and lipids, undergo damaging chemical reactions. These alterations can culminate in the development of numerous age-related diseases such as cancer, Alzheimer’s, and diabetes. Unfortunately, due to the complex nature of these diseases, many them can’t be treated in a safe and effective manner using traditional small-molecule pharmaceuticals. The Hubbard lab develops and explores the use of unconventional next-generation therapies for the treatment of cancer and other age-related pathologies.
Our lab is heavily engaged in developing new technologies including gene editing systems that can directly reverse disease-causing mutations (e.g. CRISPR/Cas9), biologics and xenobiologics capable of regulating targets considered non-druggable (e.g. synthetic peptides and nucleic acids), and support systems for cell-based therapies (e.g. cryoprotective agents). Because many macromolecular therapeutics are too large to penetrate into cells, we are also working on new paradigms for their intracellular delivery. Some of these include the use of specialized cell penetrating biomolecules and viruses.
While we predominately focus on applying these tools to better understand and treat cancer and age-related disorders, we envision that our fundamental technological developments will have broad medical significance, with implications for the treatment of hereditary and infectious diseases also.
