Research:

I. Evaluating sunscreen photophysics.

Sunscreens are designed to reside in the upper layers of the skin, absorb UV light, and dissipate the energy harmlessly as heat, preventing skin damage and carcinogenesis. However, rates of skin melanoma are still rising, despite the increased use of improved sunscreens for over a decade. Major possible reasons for this apparent sunscreen failure are

The primary aim of this project is to develop in vitro protocols for measuring the possible occurrence of transfer of UV energy, absorbed by a sunscreen, to DNA. Sunscreen agents like octyl salicylate, octyl methoxycinnamate, and Padimate O are oily substances which normally separate from aqueous environments where DNA might reside. However, cells abound in heterogeneous, boundary environments where hydrophobic and hydrophilic molecules coexist. We model this heterogeneous environment by adsorbing hydrophobic molecules to the surface of micro/nano spheres and observing spectroscopic effects when DNA is brought near. We also are attempting microscope imaging studies of this molecular adsorption process, as well as imaging of DNA with inserted fluorescent bases.

II. Monitoring DNA structural changes and interactions using fluorescent bases.DNA with modified, fluorescent base

  The two primary molecules of life are proteins and DNA. DNA stores information and proteins translate the information into the structures and processes of life. The importance of the dynamics of biomolecular structures to life is clear: DNA can be replicated or repaired only when it interacts with proteins and flexes in structure. To measure biomolecular structure and dynamics we presently emphasize experimental fluorescence methods. We describe how, how much, and how fast DNA structures change, aiming to explain the molecular mechanical mechanisms of DNA/protein activity. We presently focus on the spectral and time-resolved fluorescence properties, including energy-transfer properties, of fluorescent bases (e.g., 2-aminopurine) inserted into oligonucleotides with a variety of neighboring bases, including the DNA recognition site of  the endonuclease Eco RI.  We are also interested in the incorporation of fluorescent bases into cellular DNA using natural, metabolic processes and new DNA fluorescence bases, e.g., pteridine derivatives (M. Hawkins, NIH Pediatrics Branch) .
