Dr. Mapp works on developing a molecular-level picture of inducible gene expression in eukaryotes using organic molecules as mechanistic probes. Regulated gene expression is critical for cellular existence, and a number of human diseases such as cancer and diabetes have been linked to aberrant patterns of gene expression. She works on the discovery of transcription-based therapeutics capable of reprogramming gene expression in diseased cells while leaving normal cells unaffected. While a general sequence of events that leads to gene up-regulation is agreed upon, the molecular-level interactions that regulate the levels and time course of transcriptional activation remain unknown. A more detailed picture of gene regulation is a prerequisite for the eventual development of transcription-based therapeutics.
