The Lupold laboratory focuses on prostate cancer biology with the goal of exploiting prostate tissue-specificity to develop new diagnostic, prognostic and therapeutic agents.
Research projects stem from basic cancer biology—such as studying the role of microRNAs in the prostate cancer phenotype—to translational projects, such as targeted siRNA and gene therapy.
One area of interest is high-diversity polymer libraries, including aptamers and peptides, which can be screened to identify high-affinity cancer ligands.
Using this approach, Dr. Lupold developed the first RNA aptamers targeted to a cancer cell-surface antigen. He and others have applied these PSMA-targeting aptamers to deliver various therapeutic and imaging packages to prostate cancer cells and tumors.
Dr. Lupold is involved in additional research projects that focus on prostate cancer biology and developing experimental diagnostic and therapeutic agents for urologic cancers.
He also co-holds four patents related to his research.
