Toolkit underway at WashU may give researchers insight into cancer

By studying the effects of a biochemical process on protein function, Kristen Naegle, a biomedical engineer at Washington University in St. Louis, hopes to identify new therapeutic interventions for cancer.

Kristen Naegle, assistant professor of biomedical engineering in the School of Engineering & Applied Science, has received a three-year, $610,000 grant from the National Institutes of Health’s National Cancer Institute to create a toolkit that will allow biomedical engineers to study the effects of tyrosine phosphorylation, which becomes dysregulated in cancer. The toolkit would be a fast, inexpensive and accessible way for researchers to produce phosphorylated and soluble proteins compared to current methods.

Phosphorylation is a process through which a phosphate group is added to a protein by an enzyme called a kinase. It is important in regulating cell signaling but is difficult to study, Naegle said.

The funding will allow Naegle’s lab to compare the function of phosphorylated forms of protein domains that are involved in signaling networks with an unphosphorylated form and study their relation to cancer.

“We see these phosphorylation sites popping up in cancer and see them regulated by drugs we give to cancer patients,” she says. “It suggests that phosphorylation of these domains is involved in cancer progression. There are enough cancer patient samples to suggest that this is going to be relevant to human health as well as to basic human development.”

Naegle has a patent pending on the technology and is working with the university’s Office of Technology Management.

The McKelvey School of Engineering at Washington University in St. Louis promotes independent inquiry and education with an emphasis on scientific excellence, innovation and collaboration without boundaries. McKelvey Engineering has top-ranked research and graduate programs across departments, particularly in biomedical engineering, environmental engineering and computing, and has one of the most selective undergraduate programs in the country. With 140 full-time faculty, 1,387 undergraduate students, 1,448 graduate students and 21,000 living alumni, we are working to solve some of society’s greatest challenges; to prepare students to become leaders and innovate throughout their careers; and to be a catalyst of economic development for the St. Louis region and beyond.
