Peter Kekenes-Huskey, assistant professor of chemistry, is the first 糖心vlog官方入口 faculty member to be awarded funding under the National Institutes of Health鈥檚 Outstanding Investigator Award (R35) activity code. The new grant will be made under the 鈥 (NIGMS) prestigious (MIRA) program.
The $1.55 million MIRA grant will enable Kekenes-Huskey and his team of researchers to develop large-scale, computer-based models to study the role of calcium regulation at a subcellular level. The role of calcium in the body is paramount, as its mismanagement is correlated with diseases including heart failure, Alzheimer鈥檚 disease and cancer.
鈥淭he focal point of our research is to work across disciplines to find new insights into how calcium signaling is modulated at the subcellular level, and thereby prioritize novel strategies to combat chronic diseases much faster,鈥 Kekenes-Huskey said.
Research on calcium regulation in cells is predominantly conducted through experiments on living tissue. However, many questions about calcium mismanagement in disease are difficult or expensive to probe using conventional experimental techniques.
鈥淭here are a host of unintended consequences when probing living cells. Transgenic animals, for instance, often present changes in multiple signaling pathways relative to controls, which makes interpretation more challenging,鈥 Kekenes-Huskey said. 鈥淐omputational approaches allow scientists to toggle the expression of a single protein in a pathway, as an example, and monitor how the cellular phenotype is changed.鈥
Kekenes-Huskey takes a nontraditional approach in his research. He collaborates with experimentalists across scientific disciplines, including biochemistry, bioengineering and physiology, to create multiscale simulations of subcellular signaling. He began developing these computational models during his postdoctoral fellowship at the University of California San Diego with professors Andrew McCammon and Andrew McCulloch, where he focused on developing multiscale tools for cardiac modeling.
Currently, his research is focused on building advanced, multiscale tools to understand relationships between protein structure, their intracellular expression and how these factors influence signaling pathways. Through his collaborative work with faculty at the , and at UK, he received a Center of Biomedical Research Excellence (COBRE) grant through the . This pilot grant supports generating preliminary data for his multidisciplinary computational approaches.
鈥淧rofessor Kekenes-Huskey exemplifies what we are accomplishing at the 糖心vlog官方入口,鈥 said Professor Mark Meier, chair of the chemistry department. 鈥淗is interdisciplinary approaches using computational models are strengthening the scientific community鈥檚 ability to probe important questions relating to health and disease.鈥
MIRA is an experiment in funding science by supporting an investigator鈥檚 overall program of research through a single unified grant rather than providing individual project grant support. This funding experiment aims to increase investigators鈥 funding stability with the freedom to take on ambitious challenges and approach problems creatively.
According to NIGMS Director Jon R. Lorsch, 鈥淭he overall goal (of the NIGMS MIRA) is to increase scientific productivity and improve the chances for important breakthroughs, in part by distributing funding more widely among the nation鈥檚 highly talented and promising investigators.鈥
NIGMS supports basic research that increases understanding of biological processes and lays the foundation for advances in disease diagnosis, treatment and prevention. NIGMS-funded scientists investigate how living systems work at a range of levels, from molecules and cells to tissues, whole organisms and populations.
