Tak W. Mak, Campbell Family Institute for Breast Cancer Research, Toronto, ON, Canada For the last three decades, the “Oncogene Revolution” prompted investigators to concentrate on the development of agents against oncogenes, with the goal of blocking cell growth and metastasis. It has now become clear that the cancer cell genome is too varied and the number of oncogenes too numerous for this strategy to work effectively for most tumors. A relatively new and promising approach is to enhance the infiltration into the tumor microenvironment of leukocytes that can kill cancer cells. Two other classes of target genes relevant in this context are those involved in cancer cell metabolic adaptation and the maintenance of aneuploidy. In this review, I discuss recent data from our group and other laboratories aimed at exploiting these strategies. Abnormalities in the gut microbiota have been implicated in a variety of diseases including obesity, inflammatory bowel diseases, and cancer. However, most of these studies have largely focused on “Who is there?” There is a need for functional and mechanistic studies to determine how the microbiota or microbial products initiate and promote carcinogenesis. One might then take this bench to bedside and bedside to bench approaches. This session will discuss results from recent studies that provide evidence that shifts in microbial communities or specific microbes promote or protect against colorectal adenomas and cancer. The presentation will also include a discussion of potential mechanisms and associations with diet and inflammation, and will address future directions in the field. Room 121, Pennsylvania Convention Center Multiple Biochemical Pathways Controlling Cell Death Xiaodong Wang, National Institute of Biological Sciences, Beijing, China Room 108, Pennsylvania Convention Center DNA Damage, Checkpoint Signaling, and Therapeutic Opportunities Helen M. Piwnica-Worms, The University of Texas MD Anderson Cancer Center, Houston, TX Genotoxic stress induces cells to adopt alternate fates depending on the cell type and the extent of accumulated DNA damage. These include cell death (apoptosis), permanent cell cycle arrest (senescence), or recoverable cell cycle arrest (through activation of cell cycle checkpoints and DNA repair). DNA damage activates the ATM and ATR signaling pathways, which in turn utilize downstream checkpoint proteins including CHK1, CHK2, and p53 to regulate the cellular response to DNA damage. Loss of checkpoint integrity is a universal feature of cancer cells. This session will discuss how an understanding of fundamental principles governing cell cycle and checkpoint control can potentially be exploited to target cancer cell vulnerabilities. Efficacy of different cancer therapies often depends on the efficiency of these therapies, regardless if it is chemo, radiation, or immune-based, to induce cancer cell death. Apoptosis, a form of cell death mediated by the activities of a group of intracellular proteases named caspases, has been occupying the center stage of cell death research. Recently, a new form of programmed cell death mediated by receptor-interacting kinase 3, RIP3, and its substrate MLKL, a pseudokinase, has drawn major attention from the research field. This form of cell death is negatively regulated by caspase activities and is dispensable for animal development reproduction. However, emerging evidence has indicated that this form of cell death, also termed necroptosis, has a significant involvement in the pathological process of many diseases.

Issues that investigators need to consider which will be discussed include: 1) consenting patients/parents to clinical genomics, 2) the range of pathogenic mutations related to the patient’s phenotype being returned, 3) how to handle variants of uncertain significance in cancer genes, 4) how to approach the return of incidental findings, 5) planning for the possibility of patient demise prior to return of results and 6) what forms of validation are being used prior to returning results. and enhance integrin signaling in a vicious feed forward circuit.

Room 120, Pennsylvania Convention Center Tissue Tension Engages Developmental Programs to Promote Tumor Progression Understanding Sensitivity and Resistance to Targeted Therapeutics and Immunotherapeutics Using Mouse Models of Lung Cancer Valerie M. Weaver, UCSF Medical Center, San Francisco, CA Kwok-Kin Wong, Dana-Farber Cancer Institute, Boston, MA All cells experience force and possess mechanosensory mechanisms that enable them to detect physical stimuli and to transduce these cues into biochemical signals that modulate cell and tissue behavior. Tumors consistently exhibit abnormally high cell and tissue level forces and transformed cells demonstrate perturbed mechanosensing. We have been studying how cells sense and transduce mechanical cues to regulate their behavior and the physiological relevance of altered mechanical force in cells and tissues to tumor formation and metastasis. Using an array of in vitro and in vivo models we find that the ECM progressively stiffens in various solid tumors including breast, pancreas, glioblastoma, and skin, and we have been able to show that ECM tension modulates transition to invasion and metastasis. ECM stiffness compromises tissue morphogenesis and destabilizes tissue architecture by promoting integrin focal adhesions which potentiate growth factor receptor signaling and induce cytoskeletal remodeling and actomyosin contractility. By enhancing integrin signaling to ERK and PI3 kinase, ECM stiffness potentiates the tumorigenic effects of oncogenes and promotes tumor progression and aggression. Recently, we could show that a stiff ECM promotes tumor aggression by compromising the tissue vasculature to induce hypoxia and activate HIF1a and by directly activating HIF1a. High tumor HIF1a in turn alters tissue metabolism, stimulates inflammation and induces an epithelial to mesenchymal transition. We also find that many oncogenes such as Ras or ErbB2 or the loss of signaling in tumor cells such as the absence of TGF beta increase tumor cell contractility. We find that high tumor cell tension also induces malignancy and contributes to tumor aggression by inducing ECM remodeling and stiffening to drive focal adhesion assembly Genetically engineered mouse (GEM) cancer models have proved invaluable in cancer drug development. In the era of precision medicine, these models facilitate the understanding of primary and acquired resistance mechanisms to novel therapeutics stratified by the genotypes of the cancers in these GEM models. In addition, GEM models are one of the few model systems in which cancers are initiated and progressed within an intact immune system. This session will highlight the recent advances in the different approaches used with the lung cancer GEM models to understand the mechanisms of sensitivity and resistance to targeted therapeutics, immunotherapeutics, as well as combination therapies. Room 115, Pennsylvania Convention Center April 18-22, 2015 • Philadelphia, PA Room 103, Pennsylvania Convention Center Update on Targeting PI3Kα in Breast Cancer José Baselga, Memorial Sloan Kettering Cancer Center, New York, NY PIK3CA, the gene encoding for p110α, is frequently mutated in hormone-dependent breast cancer. PI3Kα specific inhibitors have shown remarkable clinical activity in the phase I setting in patients with breast tumors that harbor PI3Kα mutations and these agents are also entering now phase III studies in combination with hormonal therapies. The underlying reason to study these agents in combination with hormonal therapies is compelling. The PI3K and ER pathways cooperate in tumor progression. In addition, antiestrogen therapy induces the activation of the PI3K pathway in vitro and we have also observed that PI3K inhibition results in a powerful activation of ER signaling. 575 14_15AM_Wed_Layout 1 3/27/15 12:25 PM Page 576 PLENARY SESSION Wednesday, 8:00 a.m.-10:00 a.m. Terrace Ballroom I-IV (400 Level), Pennsylvania Convention Center Oncology Meets Immunology: Not Just Another “Hallmark” Chairperson: Robert H. Vonderheide, Abramson Cancer Center of the University of Pennsylvania, Philadelphia, PA It is now well-appreciated that a fundamental aspect of cancer biology involves interactions of neoplastic cells with the immune system, which can either promote or inhibit tumor growth, depending on complex networks in the tumor microenvironment. Mechanistic insights from basic studies in cancer immunology have resulted in novel, rational therapeutics for patients with advanced cancer that have produced unprecedented clinical results, even in tumors not previously regarded as amenable to such approaches. The consensus in the field – to be illustrated in this Plenary Session – is that we have only seen the tip of the iceberg for cancer immunotherapy, posing a challenge to investigators, advocates, government, industry, and others to capture this opportunity quickly and fully for the benefit of our patients. 8:00 a.m. Engineering improved cancer vaccines Glenn Dranoff, Novartis Institutes for BioMedical Research, Cambridge, MA 8:30 a.m. Leukocytes as targets for therapy in solid tumors Lisa M.

Zanetti, National Cancer Institute, Rockville, MD Transdisciplinary research is defined as research efforts conducted by investigators from different disciplines working jointly to create new conceptual, theoretical, methodological, and translational innovations that integrate and move beyond discipline-specific approaches to address a common problem. When compared with traditional unidisciplinary research, transdisciplinary research has considerable potential to accelerate scientific discovery and its translation to practice. Current NIH transdisciplinary research initiatives include the National Institutes of Health Centers for Population Health and Health Disparities (CPHHD) and National Cancer Institute Transdisciplinary Research on Energetics and Cancer Initiative (TREC). The CPHHD program responds to a strategic priority at the NIH to address disparities and inequities in the prevalence and outcomes of several diseases, particularly cancer and heart disease. This program requires transdisciplinary research involving social, behavioral, biological, and genetic research to improve knowledge of the causes of health disparities and devise effective methods of preventing, diagnosing, and treating disease and promoting health. The program began in 2003 and has funded 19 Centers since its inception, with 10 of the Centers being supported by the NCI. The TREC initiative is a scientific research effort aimed at reducing cancer linked with obesity, poor diet, and low levels of physical activity. The NCI established the TREC initiative in 2005 in response to growing public health concern with overweight and obesity in the United States and mounting evidence that obesity plays a role in the development of many types of cancer. The Centers included scientists from multiple disciplines and encompassed projects spanning the basic biology and genetics of behavioral, socio-cultural, and environmental influences on nutrition, physical activity, weight, energy balance, energetics, and cancer risk. The current TREC initiative expands into other research areas including cancer survivorship, childhood obesity, genomics, and environmental aspects of obesity that include use of tools such as geospatial analysis. This session will include a brief introduction and presentations by researchers who have been funded and/or are currently funded through the CPHHD program and TREC initiative. The session will highlight and discuss the necessary resources and strategies to address the scientific and logistic complexity of large transdisciplinary initiatives, including a discussion of leadership and management challenges and communications and decision-making procedures. Specifically, the presentations in this session will highlight best practices for performing transdisciplinary research as modeled though the CPHHD and TREC initiatives and will include perspectives from basic, social, clinical, and behavioral sciences researchers. This session will provide a venue to explore the opportunities and challenges to achieve truly transdisciplinary research from these varying scientific perspectives. The goal of this session will be to provide a forum at which investigators with extensive experience in performing transdisciplinary research within large initiatives can stimulate discussion and ideas for improving collaborations to prevent, diagnose, and treat cancer and promote health. Moreover, attendees will benefit from a deeper understanding of how large transdisciplinary collaborations are developed and managed effectively to address critical research questions.

Eaves, BC Cancer Agency, Vancouver, BC, Canada Chairperson: Bo Lu, Thomas Jefferson University Hospital, Philadelphia, PA Tumors arise as rare events from cells present in established tissues, typically through a multistep process that may span many years and likely multiple cell generations. Most tumors with the attributes of invasive malignant cells are also capable of continuous growth in vivo through the generation of a self-sustaining progeny line; hence the concept of tumor stem cells. As in normal tissues, heterogeneity of biological as well as phenotypic features is also a cardinal feature of the individual cells produced by malignant populations. However, tumors are not only genetically perturbed populations, they are also constantly evolving genetically – characteristics that add further causes of diversification in their make-up. These issues underscore the importance of clonal tracking methods to analyze the process of tumor initiation, establishment and maintenance. This Symposium will highlight new and unexpected insights obtained using clonal approaches to delineating the process of tumor propagation and evolution in various different tissues in vivo. Combining immune checkpoint inhibitors such as PD1 or PDL1 inhibitors and ablative radiotherapy has the theoretical advantage of inducing synergistic immune response against cancer cells that have developed metastases. Potential therapeutic gain from such combination in stage IV cancer patients will be unprecedented and of high clinical impact. The speakers in this session will provide preclinical results and clinical data to demonstrate viability of such strategy as well as the need for optimization. These investigations will provide valuable guidance for designing relevant clinical trials of combing immunotherapy with ablative radiotherapy. 10:00 a.m. Introduction 10:10 a.m. Defining the origin of tumor heterogeneity in epithelial cancers [SY45-01]* Cedric Blanpain, Université Libre de Bruxelles, Bruxelles, Belgium 10:30 a.m. 10:35 a.m. 10:00 a.m. Introduction 10:10 a.m. Targeting immune checkpoints in cancer therapy: New insights and opportunities James P.

However, the field continues to discover new epigenetic mechanisms that contribute to cancer etiology. These include the recently discovered oxidized 5-mC bases, such as 5-hydroxymethylcytosine. This discovery has brought with it a new appreciation that the dynamics of DNA methylation/demethylation play an important role in the etiology of many cancers. It is now also becoming clear that epigenetic alterations contribute to the development hereditary cancers. The epigenetic landscape greatly influences the penetrance of inherited mutations in genes that predispose to cancer, and in some settings, constitutional “epimutations” disrupt expression of these genes via epigenetic rather than mutational mechanisms to increase cancer risk. Unlike mutations, “epimutations” exhibit non-Mendelian inheritance and can be reversible between generations. Finally, epigenetic programmers are emerging as a unique target for environmental exposures early in life, which disrupt the activity of epigenetic “readers, writers, and erasers” to reprogram the epigenome and increase individual risk of developing cancer in adulthood. 10:00 a.m. Introduction 10:10 a.m. Title and speaker to be announced 10:25 a.m. Discussion 10:30 a.m. Deciphering the sixth base (5-hydroxymethylcytosine) in the cancer genome Yun (Nancy) Huang, Texas A&M University Health Science Center, Houston, TX 10:45 a.m. Discussion *An extended abstract for this presentation is available in the Invited Abstracts section of the Proceedings (the abstract number is listed in brackets above). **NextGen Star, selected to give a talk by the AACR President and Annual Meeting Program Chairperson through a competitive application process designed to bring more visibility to early-career scientists.

Fearon, Cold Spring Harbor Laboratory, Cold Spring Harbor, NY, and Weill Cornell Medical College, New York, NY A characteristic of cancers is their association with a stromal microenvironment that is replete with cells of the innate immune system, which has been likened to a “chronic healing wound” and a tissue-protective process. Conversely, cancers also frequently induce adaptive immune responses that lead to the accumulation of cancer-specific CD4+ and CD8+ T cells, which could cause tissue injury that, in this instance, would be beneficial for the host. The speakers in this session will discuss our understanding of the interplay of innate and adaptive immunity that leads to the promotion or suppression of tumor growth. 10:00 a.m. Introduction 10:10 a.m. Regulatory T cells in cancer Alexander Rudensky, Memorial Sloan Kettering Cancer Center, New York, NY Room 103, Pennsylvania Convention Center Nucleotide Metabolism in Cancer Cell Growth and Survival Chairperson: Brendan D. Manning, Harvard School of Public Health, Boston, MA In recent years, studies on cancer cell metabolism have led to the reemergence of interest in the role of nucleotide metabolism in cancer progression and treatment. It is now evident that cancer cells exhibit metabolic strategies to increase their nucleotide pools to meet the demands for RNA and DNA synthesis to fuel cell growth and proliferation. Unlike the normal cells from which they arise, cancer cells are believed to acquire their nucleotides primarily through de novo synthesis. Importantly, as exhibited with classic cancer drugs, such as 5-fluorouracil and methotrexate, targeting this nucleotide pool offers a promising therapeutic approach. This session will discuss recent advances in delineating the diverse mechanisms used by cancer cells to synthesize or obtain nucleotides and potential areas of vulnerability related to nucleotide synthesis and use. 10:00 a.m. Introduction 10:30 a.m. Discussion 10:10 a.m. 10:35 a.m. Discovery of intratumoral, antitumoral pathways through dynamic imaging Matthew Krummel, University of California, San Francisco, CA Induction of de novo nucleotide synthesis by oncogenic signaling pathways Brendan D.

Thompson, Memorial Sloan Kettering Cancer Center, New York, NY Cancer-inducing mutations have long been shown to alter proteins that participate in signal transduction and/or transcription. Recently, it has become apparent that cancerassociated mutations in metabolic enzymes can also play a pathogenic role. These mutations result in accumulations of metabolites which contribute to cellular transformation. Additional evidence suggests that oncometabolites can also be produced in trans during wound repair and inflammation, and contribute to early steps in transformation. Examples of these concepts will be presented. Room 121, Pennsylvania Convention Center Proteogenomics and Phosphoproteomics in Cancer: Analysis of the TCGA Tumor Samples Co-Chairpersons: Steven A.

Chairperson: Anil K. Rustgi, University of Pennsylvania School of Medicine, Philadelphia, PA Chairperson: Alberto Bardelli, IRCC, University of Turin Medical School, Candiolo, Italy Barrett’s esophagus (BE) is the leading recognizable risk factor for esophageal adenocarcinoma (EAC). Dietary and lifestyle variables, such as cigarette smoking, obesity, and eradication of H. pylori infection, play contributing roles in these conditions. This session will emphasize using mouse models to understand the cellular origin of BE through lineage labeling, modeling BE through other platforms (namely 3-D organoid cultures) and presenting current knowledge on the genomics and genetics of BE and EAC. Colorectal cancers (CRC) are presently classified based on clinical and histopathological features. Recently, several groups used unsupervised clustering of large gene expression datasets to delineate previously uncharted CRC subtypes. Depending on the classification, CRC transcriptional subtypes variably overlap with other molecular traits including microsatellite instability, methylation, and the mutational status of the RAS signaling pathway. This session will provide the most recent updates on this subject, as well as major advances on the biological and clinical significance of molecular classification of colorectal tumors. 10:00 a.m. Introduction Anil K.

Rosen, Baylor College of Medicine, Houston, TX Chairperson: Christine A. Iacobuzio-Donahue, Memorial Sloan Kettering Cancer Center, New York, NY This session will focus on our current understanding of the role of intratumoral heterogeneity and the microenvironment on breast tumor evolution. Questions to be addressed will be: 1) How does our understanding of paracrine signaling pathways in normal development provide new insights into functional pathways involved in intratumoral heterogeneity? 2) What is the impact of genetic heterogeneity on the progression from in situ to invasive breast cancer and from primary breast cancer to metastatic disease in treatment naive patients? 3) How can intratumoral heterogeneity in clinical breast cancer be measured and what type of heterogeneity is important? 4) How can we identify the “real” drivers of breast tumorigenesis? 5) What type of stromal heterogeneity exists in triple-negative breast cancer and how is this associated with patient outcome? Accumulating evidence indicates the multifactorial nature of PDA neogenesis, behavior, and progression. These include both cell-autonomous and non-cell autonomous factors such as somatic genetic alterations, epigenetic modifications, immunologic suppression, metabolic dysregulation and stromal remodeling, among others. Indeed, this multitude of factors likely influence one another over the natural history of the neoplasm culminating in the lethal phenotype encountered at diagnosis. The extent to which these factors play a role throughout carcinogenesis and progression, at distinct time points or within specific contexts remains to be clarified. The goal of this session is to therefore provide participants an integrated overview of the most current understanding of pancreatic cancer through distinct examples of cutting edge research in the field related to pancreatic cancer risk, early genetic events, whole genome sequencing, and metastasis. 10:00 a.m. Developmental insights into tumor heterogeneity Jeffrey M.
