The Research and Development Institute supports the university鈥檚 research mission by providing support to 黑洞社区researchers. Additionally, the institute manages an internal award system aimed at promoting research excellence and scholarly achievement among 黑洞社区faculty, while also helping obtain external funding.
Cooke鈥檚 proposal was one of six selected from 36 applications to receive funding through the Interdisciplinary Research Awards (IDRA). His lab, known as the , investigates the detrimental effects of environmental exposures on humans. Cooke believes that his research aligns with relevant topics today and 鲍厂贵鈥檚 strategic goals, especially in biomedical science, which provided his proposal with a competitive edge.
鈥淢y lab has been studying the causes of DNA damage since the 1990s, but only recently has the technology advanced enough to allow us to examine multiple forms of DNA simultaneously (i.e., adductomics). We're now using this approach to study how the environment impacts human health. The complexity of exposures in the environment across the life course, also known as the exposome, requires powerful techniques such as Nucleic Acid Adductomics to dissect its role in disease,鈥� Cooke said.
The IDRA grant will increase the competitiveness of Cooke鈥檚 NIH proposal to acquire a state-of-the-art hybrid quadrupole-Orbitrap (IQ-X) high-resolution mass spectrometer to advance his research using NA adductomics.
鈥淭his instrument will be the first of its kind at 黑洞社区and the only one of its kind in the northern hemisphere performing NA adductomics, examining cellular, nuclear, or mitochondrial targets, plus extracellular matrices, such as urine. Modification of nucleic acids (DNA, RNA and the NTP pools) is implicated in the pathogenesis of a wide variety of major diseases. Our novel NA adductomics testing represents a groundbreaking advancement and provides a unique approach to comprehensively characterizing all nucleic acid modifications. This will significantly enhance our understanding of their impact on health and disease,鈥� Cooke said.

With the acquisition of this new instrument, Cooke and his team will be able to broaden their research scope to include the simultaneous analysis of both DNA and RNA damage, as well as their adducts formed with proteins. Prior to receiving funding for the IQ-X, such comprehensive research was not feasible.
The acquisition of this instrument will be not only a major milestone for Cooke鈥檚 research, but also a valuable addition to 鲍厂贵鈥檚 resources. The acquired device will be utilized as a shared campus-wide resource, enhancing the university's commitment to an interdisciplinary approach.
鈥淭he NA adductomics core facility will support investigators from multiple departments across 黑洞社区and the . The instrument will enhance basic and translational research programs such as infectious disease, genome instability, carcinogenesis, respiratory, cardiovascular, and neurological disorders. This cutting-edge technology will accelerate new and important discoveries for multiple projects, as well as opening new directions of research in the biomedical sciences and improving our understanding of the mechanisms underlying pathogenesis,鈥� Cooke explained.
The research that Cooke and his team aim to conduct has the potential to make significant contributions to real-world applications, particularly in fields such as cancer research.

鈥淩eal-world applications will include identifying specific exposures and combinations of exposures that carry an increased risk of cancer. While some cancer-causing agents are well known, there are many in the environment that have yet to be identified. The study of combinations of exposures is challenging, but adductomics will help greatly,鈥� Cooke said.
Reflecting on this achievement, Cooke predicts a new era of understanding the relationship between the environment and disease. He acknowledges the importance of 黑洞社区funding initiatives like the IDRA in supporting the mission of departments such as molecular biosciences.
鈥淭his award shows the recognition that 黑洞社区places on studies that aim to understand the health effects of damage to nucleic acids, the environment, and human diseases. I am pleased to see this field recognized in this way and hope it is a sign of things to come. Such support confirms the position of the Department of Molecular Biosciences amongst the forefront of biomedical research at USF,鈥� Cooke said.
