Dr. Coleman is pursuing research to identify the cellular mechanisms associated with ionizing radiation (IR) exposures. This work relies on using genomic and proteomic techniques to identify and characterize transcriptional networks, such as TP53, MYC and NF-kB, that play a role in controlling cell fate in response to IR exposures. Importantly, these regulatory pathways are also utilized by the cell for cancer progression. Such information can be utilized for developing diagnostic assays and tools for biodosimetry as well as the treatment and prevention of cancer.
Dr. Coleman is also very active in the development of advance biochemical techniques using nanoparticles made of apolipoproteins and phospholipids called nanolipoproitein particles (NLPs). NLPs closely mimic the cellular membrane bilayer, and represent an ideal platform for characterizing membrane proteins involved in signal transduction. For example, NLPs are proving useful for the characterization of the structure and function of G-protein coupled protein receptors. NLPs are also proving useful for drug delivery, immuno-modulation and in vivo imaging in the treatment of cancer.
