Differential migration mechanics and immune response of glioblastoma subtypes<\/strong><\/h2>\n

Glioblastoma remains a deadly cancer driven by invasion of tumor cells into the brain. Transcriptomic analyses have revealed distinct molecular subtypes, but mechanistic and targetable differences that explain clinical differences are not clear. Using a state-of-the-art immunocompetent mouse model for glioblastoma \u2013 where tumors are induced by injection of plasmids containing human glioblastoma subtype-defining genetic drivers in a wild-type background \u2013 we found that, as predicted by the motor-clutch model for cell migration (Klank et al., Cell Rep, 2017), mesenchymal glioma cells are more spread, generate larger traction forces, and migrate faster in brain tissue compared to proneural cells. Despite their fast migration and comparable proliferation rate in vitro<\/em>, mice with mesenchymal tumors live longer than mice with proneural tumors, which was correlated with an immune response in the mesenchymal mice that included T cell-mediated killing of cancer cells, similar to human tumors. Thus, mesenchymal tumors have aggressive migration, but are relatively immunologically \u2018hot\u2019 which suppresses net proliferation, features which are captured by our Brownian Dynamics tumor simulator (Klank et al., Conv Sci Phys Oncol, 2018). These two features counteract each other and may explain the lack of a strong survival difference between subtypes clinically, while also opening up new opportunities for subtype-specific therapies.<\/p>\n

David Odde is the Medtronic Professor of Engineering in Medicine at the University of Minnesota. Trained as a chemical engineer at the University of Minnesota and Rutgers University, Odde joined the newly created Department of Biomedical Engineering at the University of Minnesota in 1999 where he is a professor and Associate Director for Strategic Research Initiatives in the Institute for Engineering in Medicine. In his research, Odde\u2019s group builds computer models of cellular and molecular self-assembly and force-generation-dissipation dynamics, and tests the models experimentally using digital microscopic imaging of living cells ex vivo<\/em> and in engineered microenvironments. His group seeks to bring an engineering approach that uses physics-based modeling and analysis to understand, predict, and control disease outcomes (oddelab.umn.edu). Dr. Odde is an elected Fellow of the American Institute for Medical and Biological Engineering (AIMBE), the Biomedical Engineering Society (BMES), the International Academy of Medical and Biological Engineering (IAMBE), and the American Association for the Advancement of Science (AAAS) and is the Director of the Physical Sciences in Oncology Center at the University of Minnesota (psoc.umn.edu), which is focused on modeling the mechanics of cancer cell migration in biologically relevant contexts.<\/p>\n","protected":false},"excerpt":{"rendered":"
