Dana-Farber Cancer Institute PS-OC
Dana-Farber Cancer Institute Physical Sciences-Oncology Center (PS-OC)
The principal mission of this PS-OC is to promote the understanding of cancer evolution and treatment responses utilizing approaches from the physical sciences intertwined with cancer biology and oncology.
It is investigating the treatment response of leukemic, brain and breast cancer cells and their microenvironments to classical and novel treatment approaches. It is developing novel mathematical frameworks describing the evolutionary dynamics of tumor progression and treatment response that are parameterized using the experimental systems, as well as predicting and validating optimum intervention strategies that will ultimately be implemented as prospective clinical trials. This approach is incorporating the spatio-temporal organization of evolving, heterogeneous tumor cell populations within their microenvironment.
Collaborations between physical and experimental scientists in the PS-OC will bridge the chasm between the physical sciences and oncology with the ultimate goal of uncovering novel biology and enhancing patient care.
Project 1: Prospective Clonal Dynamics Guiding Curative Therapies for Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a rapidly fatal disease that can quickly be brought into complete remission, but with high relapse rates. The genetic evolution of the disease has been defined, but the basis for resistance to therapy and effective strategies to overcome it are lacking.
This project is using well-defined murine models where an analogous form of highly lethal, human AML can be temporarily brought into remission by traditional chemotherapy agents. Combining these basic features with novel strategies for quantitatively assessing oncological behavior and cell growth patterns, this study is providing multidimensional datasets for mathematical modeling of disease progression and susceptibility to therapeutic approaches.
Ultimately, these models will be used to predict and test unique vulnerabilities of the disease that can be exploited therapeutically to reduce AML relapse.
Project 2: Intratumor Heterogeneity Determines Best Treatment Modalities in Brain Cancer
Glioblastomas (GBMs) are the most common and most malignant primary brain tumors and can be divided into several molecular subgroups. All subtypes demonstrate high insensitivity to standard therapeutic approaches and, unfortunately, recurrence inevitably occurs.
This project is advancing the understanding of particular subtypes of GBMs and optimizing intervention strategies. Additionally, it is elucidating the combined effects of chemotherapy and radiation treatment on proneural-GBMs, to maximize radiation therapy responses in mesenchymal-GBMs and improve overall GBM treatment strategies independent of tumor subtype.
Utilizing a multidisciplinary approach of basic biological and novel mathematical models, the PS-OC investigators are determining therapeutic dynamics of treatment response to ultimately provide optimized and novel intervention strategies for GBM and improve the standard of care for patients.
Project 3: Single Cell Analyses of Intra-Tumor Heterogeneity Identify Optimum Therapies for Breast Cancer
Breast cancer is the most commonly diagnosed cancer and is the main cause of cancer-related mortality in women worldwide. Achieving a meaningful global impact on breast cancer-associated morbidity and mortality requires a better understanding of drivers of metastatic progression and therapeutic resistance at the cellular and molecular level, a way to recognize these features in diagnostic patient samples, and early intervention and treatment strategies that prevent the emergence of metastatic and treatment-resistant tumors.
The goals of this project are to tackle these key clinical problems in breast cancer through a combined mathematical modeling and experimental approach utilizing single cell analyses and xenograft models to identify optimal therapeutic strategies to ultimately prevent metastatic outgrowth and treatment resistance. Ultimately, these models will be validated in clinical and xenograft samples and they will be utilized to combat primary tumor and metastases formation.
Core 1: Single Cell Profiling
This core is a virtual infrastructure led by Dr. Rong Fan. The core provides the capability of characterizing single cells at the omics level in order to dissect intra-clonal cellular heterogeneity, discover molecular correlates, and refine the parameters used to gauge tumor cell fitness in computational modeling. The core will support the PS-OC by offering services to measure the transcriptome, epigenome, and proteomic signatures in single cells.
While researchers in individual PS-OC projects will track clonal growth and molecular signature changes of each clone, the core will characterize cellular heterogeneity within individual clones, especially at the omics level. Additionally, the core is a technology innovation center that aims to develop new technology platforms to enable new opportunities of scientific discoveries. Thus, the core itself involves substantial engineering innovation and represents an important component of the PS-OC.
Education and Outreach Unit
This PS-OC is facilitating integrative science through education and outreach, as well as supporting career building opportunities and synergistic collaborations with clinicians, experimentalists, and physical scientists with diverse disciplinary background.
Our overarching goal is to expose scientists and students to a multidisciplinary environment, foster collaborative networks, and ensure career building opportunities.
