Despite advances in breast cancer treatment, metastatic disease remains incurable and is of particular concern in patients with triple negative breast cancer (TNBC). Both aberrant metabolic signaling and physical properties of the microenvironment have been independently defined as hallmarks of cancers, and experimental evidence suggests that they may be functionally linked. However, the current lack of physiologically relevant culture models that capture relevant physical details prevents studying the specific mechanisms that link metabolic reprogramming, the physical microenvironment, and clinical outcomes of malignancy. By leveraging capabilities of five different institutions (Cornell University, Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center, MD Anderson Cancer Center, University of California San Francisco) the Cornell Physical Sciences Oncology Center (PSOC) will interrogate the multiscale biological and physical (structural, mechanical, and solute transport) mechanisms regulating tumor metabolism and function, as well as the consequences on tumor development, metastatic progression, and therapy response. Project 1 will test the physical mechanisms by which the microenvironment regulates tumor metabolism and how obesity affects this interplay, Project 2 will investigate the role of altered metabolism and the physical microenvironment in modulating the biogenesis and function of microvesicles, Project 3 will evaluate the integrated effects of physical and metabolic constraints on tumor cell migration and invasion. Two Cores will provide computational modeling and microfabricated, patient-derived culture platforms with physiologically relevant metabolic stresses, mechanical cues, and transport phenomena (Core 1) and will assist in state-of-the-art imaging analysis of cellular metabolic state, microvesicle characterization, and nanoscale cellular properties (Core 2). The Education and Outreach Unit will train interdisciplinary cancer researchers who are able to effectively engage across multiple sectors (academia, industry, government) to move treatment forward. Collectively, our proposed PSOC will generate physical sciences-driven mechanistic insights into TNBC with the ultimate promise of improving clinical outcomes.

Project 1: Effects of the Physical Microenvironment on Metabolism
Triple negative breast cancer (TNBC) and obesity lead to physical changes in the microenvironment, including aberrant multiscale structure and mechanics of the extracellular matrix, disturbed distributions of soluble factors, and population-level abnormalities in collective cell behavior. However, the functional interconnections between these physical variations and tumor metabolism remain unclear. This gap in understanding can be attributed to a lack of computational and experimental models that permit reliable prediction, recapitulation, and study of tumor and obesity-associated physical mechanisms in TNBC. By integrating biomaterials, tissue engineering, microfabrication, and computational models, Project 1 will investigate the hypothesis that physical changes in the microenvironment regulate malignancy by perturbing cellular metabolism. Furthermore, we will test whether obesity primes for tumorigenesis through similar mechanisms. To address these hypotheses, engineering-centric approaches will be integrated with transgenic mouse models, patient-derives xenografts, patient-derived organoid cultures, and drug testing. This approach will reveal novel mechanisms in tumor metabolic reprogramming for clinical translation.
Project 2: Metabolism-Mediated Changes of Microvesicle Biogenesis
Project 2 focuses on a key outcome of cancer cell metabolism: the generation of microvesicles (MVs), which are shed from the plasma membranes of cancer cells. MVs have been implicated in the metastatic process by changing the tumor microenvironment and stimulating tumor angiogenesis. Although we understand some of the biochemical signals triggering MV production, we know little about the physical determinants driving their formation, or how the physical microenvironment influences their biogenesis and function. We will probe these issues as follows: 1) Determine the physical relationships governing MV biogenesis and size distribution; 2) determine the reciprocal relationship between the physical properties of the extracellular matrix and MV formation; 3) establish physical read-outs such as vesicle size as indicators of MV function in tumor-stroma and reciprocal stroma-tumor vesicle transfer. These studies should shed new light on how cancer cell metabolism stimulates MV biogenesis, and ultimately lead to novel therapeutic strategies.
Project 3: Physical and Metabolic Constraints of Cancer Cell Invasion
Cancer cell invasion from the primary tumor into surrounding tissues is a crucial step of the metastatic cascade, which is responsible for the vast majority of cancer deaths. We propose that invading cancer cells must expend significant energy to penetrate through tight interstitial spaces, and adopt migration modes that minimize metabolic cost. The research in this project will address how the interaction between invading cells and the physical microenvironment determine energy consumption; how physical factors intrinsic to the cell, particularly nuclear deformability and the physical properties of the cell surface, modulate metabolic cost and migration efficiency; and how metabolic reprogramming in cancer cells affects migration efficiency by fueling biosynthetic pathways that alter cellular mechanics. The experimental work will be complemented by modeling of cancer cell metabolism and physical interaction with the microenvironment, with the objective to predict outcomes of therapeutic metabolic interventions and to identify strategies to counter adaptive responses.

Core 1: Tissue Microfabrication Core
The elucidation of biophysical mechanisms that lead to metabolic aberrations in tumors and, in turn, impact cancer progression, requires specialized capabilities for the manipulation of cells, biological materials, and tissues and for the development of computational models to evaluate hypotheses and interpret experimental data. Additionally, the assessment of the clinical relevance of these mechanisms and their translation toward therapeutic applications requires coordinated access to patient-derived samples with thorough clinical and genetic profiling and data basing. The Tissue Microfabrication Core will provide project investigators a shared infrastructure that satisfies these requirements organized into three aims: 1) management of the acquisition, clinical and genomic characterization, data banking, and distribution of patient derived tissues; 2) development and fabrication of advanced culture platforms and microfluidic devices for the characterization of cells and biomaterials; and 3) hierarchy of computational models to support metabolic analysis and the design and interpretation of experiments.
Core 2: Biophysics and Metabolic Imaging Core.
The Biophysical and Metabolic Imaging Core provides the optical imaging instrumentation, facilities and expertise for the high resolution imaging, biophysical analysis and image processing tasks required by the three PSOC projects, as well as any pilot or trans-network projects that may develop. We provide high-end microscopy instrumentation for dynamic measurements of the cellular metabolic state using both fluorescent metabolic sensors and intrinsic sources such as NADH and FAD containing proteins, for the visualization of tissue morphology, microvesicle shedding and for quantitative imaging of cellular nanoscale mechanical properties using several forms of super-resolution microscopy. The Biophysical and Metabolic Imaging Core leverages both state-of-art commercial instrumentation, as well as custom-built instruments specifically optimized for the research needs of PSOC investigators and their projects.
Education and Outreach Unit
We develop training tailored to the needs of physical scientists entering cancer research and to cancer biologists adopting physical science approaches. Training elements include classroom instruction, lab-based minicourses, and immersion experiences. For physical science trainees, the focus is on gaining a solid grounding in modern cancer biology, developing critical laboratory skills that are less common in the physical sciences, and gaining exposure to clinical medicine and translational research. For cancer biology trainees, the goal is to learn what physical science methods enable in biomedical research, develop aptitude in applying these approaches, and see an engineering lab from the inside. Both groups of trainees participate in an innovative, student-led course on metabolism in cancer. Other programs aim to broaden the perspective of trainees and include a trainee-led Cancer Brainstorming Club, interactions with patient advocates, and planning for diverse careers. These activities aim to facilitate interactions between physical science/engineering and cancer biology/oncology that enhance cancer research.

Education and Outreach Activities
We connect trainees with cancer patients and survivors on an on-going basis through a collaboration with the Cancer Resource Center of the Finger Lakes. The objectives of this collaboration are to provide trainees with: 1) the communication skills needed to present their research in lay language, 2) an opportunity to see the human dimensions of cancer, and 3) an understanding that researcher-patient partnerships are mutually beneficial. Training experiences include classroom instruction that emphasizes science communication, multiple opportunities to present cancer research to the local community, and involvement in patient support activities at the Cancer Resource Center. By teaching - and learning from - cancer patients, trainees gain a unique perspective on cancer that complements their more traditional research training. Community members have the opportunity to see cancer research first-hand, gaining an appreciation of its complexities, and insight into the future of cancer prevention, diagnosis, and treatment. The partnership began with a focus on doctoral students and post-doctoral trainees in the College of Veterinary Medicine and in the Nancy E. And Peter C. Meinig School of Biomedical Engineering, but has expanded to include students at all levels of study from throughout Cornell. Recent participants have included undergraduate and masters students from various disciplines including engineering, social sciences, the humanities, and health administration. The website for this partnership highlights the varied activities that are available.
