We are excited to announce the formation of a new Physical Sciences-Oncology Center at the University of Minnesota! David Odde is a director of the brand new "Center for Modeling Tumor Cell Migration Mechanics" - an $8.2 million, 5-year award from the National Cancer Institute. Along with co-directors Dr. David Largaespada (UMN Dept. of Pediatrics and Masonic Cancer Institute) and Dr. Steven Rosenfeld (Cleveland Clinic Brain Tumor and Neuro-oncology Center and Dept. of Cancer Biology), and involving multi-disciplinary research groups at the University of Minnesota, Mayo Clinic, and Cleveland Clinic, this grant will fund research focused on understanding the mechanics of cancer cells and their environment in high grade tumors. Cell migration is a common feature of high-grade cancer, so developing a computational "flight simulator" for cancer cell migration could lead to new therapies that can disable cell migration and improve patient outcomes!
David Odde, Ph.D., IEM Cellular and Molecular Bioengineering Theme Co-Chair and Professor of Biomedical Engineering, is a Co-Principal Investigator on a recently awarded R01 grant from the National Institute on Aging. In collaboration with Dr. Elizabeth Rhoades (Principal Investigator, U. of Pennsylvania, Dept. of Chemistry) and Dr. Jonathan Sachs (Co-Investigator, U. of Minnesota Dept. of Biomedical Engineering), the $2.3 million 5-year grant will fund research into the molecular mechanisms of tau, a protein involved in Alzheimer's disease.
One of the hallmarks of Alzheimer's disease is the loss of function of the microtubule-associated protein tau, which leads to microtubule destabilization and disruption of normal neuronal function. One possible mechanism is that disease-specific modifications to the tau protein disrupt motor-based protein trafficking along axons through altered microtubule organization and dynamics. The goal of this collaborative project is to develop a molecular level understanding of tau's mechanism of action on microtubule assembly dynamics in both normal and disease-specific tau variants that affect tau-microtubule interactions. Using computational modeling, in vitro experimental analysis of purified proteins, and imaging microtubules in living cells, this project will develop a detailed biophysical mechanism of tau function towards the goal of being able to predict changes in cellular function from molecular-scale modifications to the tau protein. Results from this research will guide future therapy development to restore normal tau function in patients with Alzehimer's disease.

The download package comes as a zip file that contains the tracking algorithm (two Matlab files) and a PDF support manual. This code update follows our recent chapter Quantitative analysis of microtubule self-assembly kinetics and tip structure in Methods in Enzymology, which contains additional information on code performance under various imaging conditions, and optimization procedures for potential user applications.
David Odde, Ph.D., IEM Cellular and Molecular Bioengineering Theme Co-Chair and Professor of Biomedical Engineering, was recently awarded a new R01 grant from the National Cancer Institute to develop an integrated modeling and microsystems approach to glioma invasion.
The $2.3M grant will involve researchers from Neurosurgery, the Masonic Cancer Center, the College of Science & Engineering and a collaboration with the Cleveland Clinic (Prof. Steve Rosenfeld, M.D., Ph.D.). A major goal will be to develop a "flight simulator" to simulate the mechanics of brain cancer cell migration in the brain, and use the simulator to identify possible therapeutic targets.
In this study, Prof. Odde and colleagues will be using a combination of advanced genetics, mouse models, and confocal light microscopy imaging to quantitatively measure glioma cell migration and force generation dynamics in live mouse brain slices. In parallel, they are developing advanced in vitro systems with controlled chemical and mechanical properties that more closely mimic normal and diseased brain tissue. Finally, these advanced experimental systems will be used to develop the "flight simulator" for the migrating cancer cells. This computer model will then be used to screen in silico for the most vulnerable nodes, and node combinations, in the mechanochemical network. Ultimately, they hope to find drug target combinations that strongly and selectively disable glioma cell migration, leading to new and more effective therapies.
