6 As a matter of record, Drs. Arap and Pasqualini have a long-standing collaboration and have led a joint laboratory since October Our research group currently includes Ph.D. or M.D./Ph.D. students, postdoctoral fellows, faculty (assistant and associate professors), research technicians, and administrative staff members. Our central working hypothesis is that differential protein expression in the human vascular endothelium associated with normal or diseased tissues offers the potential for developing novel diagnostic, imaging, and therapeutic strategies. In essence, our research program uses combinatorial library selection (peptide- and antibody-based) to discover, validate, and exploit the vascular biochemical diversity of endothelial cell surfaces that can be subsequently exploited towards a new vascular-targeted pharmacology. Such targeting technologies may lead to the development of ligand-directed, clinically applicable agents for the treatment of cancer patients. Translational applications, such as first-in-man clinical trials, which have now started within MDACC, will ultimately determine the value of this strategy. Indeed, the Food and Drug Administration (FDA) granted “safe-to-proceed” status for our first vascular-targeted IND in A first-in-human study has already been completed with several patients enrolled in this MDACC-sponsored clinical trial. A second IND was filed mid-November 2010; subsequent questions from the FDA were addressed though extensive additional experimentation, and the second Phase I study is now active. Two other drugs are in pre-IND stage, with several others in the pre-clinical laboratory phase. Long-term, the broader vision of our research is to generate a large-scale receptor map of the human vasculature Combinatorial mapping of the human vasculature: towards ligand-directed therapies and imaging agents

8 Personalized cancer therapy has come into focus in recent years with newly developed immunotherapies complementing conventional treatment modalities. However, the transition from bench to bedside still faces significant headwinds. Mouse models often fall short in predicting the efficacies and toxicities associated with T-cell therapy. Thus, new models which more closely mimic the human condition are urgently needed. The companion canine spontaneously develops many of the same cancers found in humans, despite a functionally intact immune system. Canine cancers mirror human malignancies with similarities in mutagenesis, tumorigenic responses to environmental toxins, documented oncogenic predispositions, and intra-species genetic diversity. These parallels, coupled with their relatively large body mass, afford a unique therapeutic model to study human cancers. NHL is the most common malignancy of the domestic dog, accounting for up to 25% of canine neoplasm and is rarely curable. Similar to humans, the majority of NHL (60-80%) in dogs arise from malignant B cells, most commonly diagnosed as Stage III or IV at presentation. New approaches are needed to improve patient survival beyond what combination chemotherapy (CHOP) can currently achieve. Biological therapies, such as CAR + or CAR neg T-cell therapy, can target disease by employing mechanisms independent of chemo-radio-therapies. Clinical observations reveal that an augmented pace of T-cell recovery after chemotherapy correlates with improved tumor-free survival, suggesting the add-back of T cells after chemotherapy may improve outcomes. To evaluate adoptive immunotherapy treatment for B-lineage NHL, we expanded T cells from client-owned canines diagnosed with NHL on artificial antigen presenting cells (aAPC) in the presence of human interleukin (IL)-2 and IL-21. Graded doses of autologous T cells were infused after CHOP chemotherapy and persisted for 49 days, homed to tumor sites, and significantly improved survival. Serum thymidine kinase changes predicted T-cell engraftment, while anti-tumor effects correlated with neutrophil-to-lymphocyte ratios and granzyme B expression in manufactured T cells. Our study supports the use of add-back T cells after chemotherapy in NHL patients to improve prognosis and survival. Personalized Canine cancer therapy

Alvarez de Lacerda, Ph.D. Education: University of Coimbra (Portugal) - PharmD in Pharmaceutical Sciences University of London (United Kingdom) – PhD in Nanotechnology/Drug Delivery Systems Notable Honors/Awards: Postdoctoral Fellowship - Susan G.

Komen for the Cure®, USA Trainee of the Quarter Award - Department of Trainee and Alumni Affairs, University of Texas MD Anderson Cancer Center, USA Research Interest: My research project focuses on the role of the tumor microenvironment in regulating the equilibrium among breast cancer stem cells, progenitors, and differentiated cells. Additionally, I also have interest in new approaches to better understand and treat inflammatory breast cancer. My long-term career goal is to develop targeted therapeutic strategies that are specifically designed to overcome disease recurrence by effectively treating breast cancer stem cell populations.

10 Inflammatory breast cancer (IBC) is an aggressive variant of breast cancer characterized by blocked breast lymphatics and clinically apparent involvement of the skin resulting in erythema, swelling and a high rate of resistance to therapy. Tumor-skin invasion in IBC patients, despite being a rare event, is an event that develops very rapidly, can spread throughout the upper body and ultimately results in breast cancer death. Very little is known about this event and how to prevent it. Mesenchymal stem cells (MSC) are multipotent progenitor cells which are found in normal tissues, including the bone marrow and adipose tissue. We hypothesized that MSC are critical mediators of IBC clinical phenotype and represent targets for treatment. Our data shows a significant difference in the tumor-skin invasion, between groups of mice injected with IBC cells SUM149 with or without MSC. Furthermore, co-injection of MSC with IBC cells significantly increased the spontaneous development of metastasis after primary tumor resection. In vitro, MSC co-culture was associated with increased EGFR signaling, and tumors in MSC co- injected animals had increased p-EGFR staining by IHC. Remarkably, we found that Erlotinib inhibited the rapid development of metastasis promoted by MSC co-injection, independently of primary tumor growth rate. In conclusion, MSC increased tumor-skin invasion and metastasis development in an IBC pre-clinical model independent of growth rate. This mechanism was due to increased EGFR signaling promoted by MSC. Thus MSC-cancer cells interaction can be abolished by Erlotinib. Further studies are needed to understand the role of MSC on the IBC cell involvement in skin contributing to the aggressiveness of this deadly disease.

12 Epithelial ovarian cancer (OvCa) is one of the most lethal malignancies in women. Identification of molecular subtypes and corresponding molecular driver events is critical for the development of new therapies for OvCa patients. Here, we develop a computational pipeline (Master mIRna Analysis for Cancer moLecular subtype, MIRACLE) that aims to delineate the driver events, especially driver miRNAs. Applying the MIRACLE pipeline to 459 serous OvCa cases in TCGA database revealed a core miRNA- regulatory network for mesenchymal phenotype of OvCa. Using genes in the regulatory network, we further characterized a robust OvCa mesenchymal subtype significantly associated with poor survival in 459 serous OvCa cases from TCGA and 560 cases from three independent patient cohorts. In the miRNA-regulatory network, eight key miRNAs were predicted to regulate 89% of the targets. Among them are well- established EMT inhibitors, such as miR-200 family. In the follow-up in vitro and in vivo experiments, we further demonstrated that miR- 506, whose function was previously uncharacterized, as a novel EMT inhibitor by targeting SNAI2. Transfection of miR-506 augmented E- cadherin expression, inhibited cell migration and invasion, and prevented TGFβ-induced EMT, while force expression of SNAI2 can abolish miR-506’s effect. In human OvCa tissue, miR-506 expression was correlated with decreased SNAI2, elevated E-cadherin, and beneficial prognosis. To further explore the therapeutic efficacy of miR-506 in OvCa, we treated OvCa orthotopic mouse models with nanoparticle-incorporated miR-506. MiR-506 delivery can suppress EMT and tumor growth in vivo, suggesting miR-506 may serve as a potential therapeutic tool for OvCa patients. Integrated analyses identify a master microRNA regulatory network for the mesenchymal subtype in serous ovarian cancer

14 Diversity in the genetic lesions that drive cancer initiation and progression is extreme. This diversity exists not only among tumors from different patients, but also among cancer cells within the same patient. This nefarious complexity is, in large measure, responsible for the capacity of this disease to evade current best efforts for effective therapy. “Personalized medicine” has been proposed in response to this conundrum as a mechanism to tailor cancer treatment to a specific tumor’s genetic and epigenetic characteristics. However, selection of appropriate treatment is dramatically limited by the paucity of appropriate drugs and by the difficulty of linking treatment options to the appropriate patients. The challenge is to identify authentic intervention targets for development of an appropriately diverse cohort of therapies to contend with disease heterogeneity. We are addressing this challenge by a focused investigation of common vulnerabilities that arise as a consequence of oncogene expression and tumor evolution. Here we will describe a cancer intervention discovery pipeline using parallel genetic and chemical perturbations within an extensive panel of cell lines representative of the molecular lesions detected in lung cancer by national and international cancer genome sequencing efforts. We have found that current first line targeted therapies are discoverable within this panel together with the enrollment biomarkers required to stratify patient treatment regimens. Further, we have found that new genetic and chemical vulnerabilities can be revealed that are linked to recurrent mutations in lung cancer patients that are not currently “actionable”. We are leveraging this approach to stratify lung cancer subtypes and elaborate intervention targets that are linked to those subtypes by robust molecular discriminators.

My specific interests and expertise are in tobacco cessation for marginalized populations.

16 Compared to individuals in the general population, racial/ethnic minorities and individuals with low socioeconomic status (SES) have higher smoking rates and greater difficulty quitting smoking. Thus, smoking has a striking impact on cancer disparities and mortality for individuals from these populations. Low health literacy is one factor that may be uniquely associated with poor cessation outcomes. This presentation will describe three studies investigating relations between health literacy and tobacco use and cessation, and potential mechanisms of this association, among low-SES, racially/ethnically diverse smokers. Implications and specific aims for future research will be discussed. Tobacco-related cancer disparities: The role of health literacy

18 Cancer cells acquire motility by remodeling their cytoskeleton to form migratory structures (e.g., filopodia). Such transformations are dominated by F-actin re-assembly within the cytoplasm. These processes produce protrusive forces (~1 pN) allowing cells to migrate from their primary tumor site into surrounding stroma. Our goal is to elucidate the motility of cancer cells in vitro, by developing an assay to measure the protrusive forces and their time course. An optical trap-based biosensor with a stiffness of 9.2×10 -4 pN.nm - 1.mW -1 and time constant of 23 s -1.mW -1 is built. The trap levitates a 2-μm polystyrene bead 7 μm above the substrate. The bead undergoes a displacement from its equilibrium position in proportion to the force acting. The bead also serves as a handle to initiate the formation of the filopodium-like structure. We use a metastatic squamous cell carcinoma (HN31) of the pharynx, because they exhibit constitutively active Rho-GTPases and can sustain actin remodeling. The experiment involves bringing a cell in contact with the bead to facilitate membrane adhesion and then pulling it apart to rupture membrane-cytoskeletal bonds to initiate the formation of the filopodium-like structure. Results show the maximum force required for bond rupture is 70 pN, and decreases to 25 pN as the formed structure reaches a stationary state. Riding upon the stationary value are force fluctuations, which we associate with F-actin dynamics occurring within the cytoplasm near the tip of the structure. We suggest filopodium-like structures do form and we can monitor F- actin dynamics at its leading edge. Development of a force assay to monitor the mobility of cancer cells

I am particularly interested in investigating the multiple roles of p53 as a regulator of cell cycle, repressor of pluripotency factors and promoter of differentiation. To better understand this process I utilize mass cytometry for highly parametric profiling of cell populations undergoing differentiation.

20 Development hinges on the capability of pluripotent embryonic stem cells (ESCs) to continuously self-renew and provide a source of somatic cells through differentiation. ESCs are held in a pluripotent state by core transcription factors including OCT4 and SOX2. During early differentiation of human ESCs (hESCs) p53 actively promotes differentiation by inducing cell cycle arrest, repressing pluripotency factors and activating lineage-specific developmental genes. Our understanding of the changes hESCs undergo during differentiation is limited by the inherent heterogeneity of cellular states. To overcome this we employed cytometry by time of flight mass spectrometry (CyTOF) to quantify 30+ distinct protein abundances at the single cell level, changing the heterogeneity of differentiation from an impediment into an asset. Using CyTOF to quantify changes in cell cycle distribution, histone modifications, pluripotency and lineage- specific marker proteins during differentiation we performed novel computational analyses to define a continuum of cell states present during differentiation and pinpointed key regulatory events. Upon differentiation to either ectodermal or endodermal/mesodermal lineages we observed p53 induction and accumulation of cells in G1 phase followed by the appearance of lineage-specific markers. p53 depletion increased proliferation and pluripotency factor abundance in self-renewing hESCs and delayed but did not prevent differentiation of hESCs. Additionally, G1 arrest was diminished but not abolished during differentiation indicating compensation, potentially by p53 homologs p63 and p73 or through p53 independent ERK-mediated cell cycle arrest pathways. Our findings improve our understanding of p53’s non-apoptotic role in differentiation and establish a unique system for further investigating hESC differentiation. Dynamic changes in protein abundance and cell cycle profiles revealed by profiling of human embryonic stem cells during differentiation at the single cell level by mass cytometry

21 Keynote Speaker Professor Stanford University School of Medicine Irving Weissman, M.D. Education: Montana State College (now University)B.S.1961 Stanford UniversityM.D.1965 Notable Honors/Awards: Among others: The Robert Koch Award, Pasarow Award for Outstanding Contribution to Cancer Biology, Election to the National Academy of Sciences; California Scientist of the Year (2001); Jessie Stevenson Kovalenko Medal, National Academy of Sciences Council; Max Delbruck Award; Honorary Doctorates, from Montana State University, Columbia University, Mt. Sinai School of Medicine. Research Interest: Dr. Weissman is an expert in the field of hematopoiesis (blood- formation), leukemia, and hematopoietic stem cells. The main focus of his work for many years has been the purification, biology, transplantation, and evolution of stem cells. His laboratory was first to identify and isolate the blood-forming stem cell (hematopoietic stem cell) in mice and humans, and to define many of the stages of development between these stem cells and their differentiated progeny. In recent years, Dr. Weissman has studied the potential of CD47 as a therapeutic target in multiple cancers and identified cancer stem cells in various hematologic and solid-tumor cancers.

22 Following embryonic development, most of our tissues and organs are continuously regenerated from tissue/organ specific stem cells. The principal property that distinguishes such stem cells from their daughter cells is self-renewal; when stem cells divide they give rise to stem cells (by self-renewal) and progenitors (by differentiation). In most tissues only the primitive stem cells self-renew. Stem cell isolation and transplantation is the basis for regenerative medicine. Self-renewal is dangerous, and therefore strictly regulated. Poorly regulated self-renewal can lead to the genesis of cancer stem cells, the only self-renewing cells in the cancerous tumor. The Weissman lab has followed the progression from hematopoietic stem cells to myelogenous leukemias. They have found that the developing cancer clones progress at the stage of hematopoietic stem cells, until they become fully malignant. At this point, the ‘leukemia’ stem cell moves to a stage of a downstream oligolineage or multilineage progenitor that has evaded programmed cell death and programmed cell removal, while acquiring or keeping self-renewal. While there are many ways to defeat programmed cell death and senescence, there appears to be one dominant method to avoid programmed cell removal—the expression of the cell surface ‘don’t eat me’ protein CD47, the ligand for macrophage SIRP-alpha. All cancers tested express CD47 to overcome expression of ‘eat me’ signals such as calreticulin and asialogylycoproteins. Antibodies that block the CD47– SIRP-alpha interaction enable phagocytosis and killing of the tumor cells in vitro and in vivo. We expect to have the anti-CD47 therapies in phase 1 trials in early Normal and neoplastic stem cells

Cancer systems biology demonstrates that multiple genomic aberrations in cancer cells integrate to alter cellular functions at the level of protein.

25 The Functional Proteomics Reverse Phase Protein Array (RPPA) provides investigators with a powerful high throughput, quantitative, cost-effective technology for functional proteomics studies. The RPPA technology complements Mass Spectroscopy and tissue microarray approaches to measure total and phospho- or cleaved- protein levels. RPPA represents an antibody-based functional proteomics analysis for both tumor tissue and cultured cells. Protein extracts denatured by SDS followed by serial dilution (in order to define antigen-antibody reaction in a linear range for accurate quantification) are arrayed on nitrocellulose-coated slides and probed with validated antibodies that recognize signaling molecules in their functional state. Signals are captured by tyramide dye deposition and a DAB colorimetric reaction. Data are collected and quantified using custom software developed for this purpose. The values derived from the slope and intercept are expressed relative to standard control cell lysates or control peptides on the array. These values indicate the levels of protein expression and modification. The sensitivity of RPPA technology can detect signals at the concentration of a femtogram from micrograms of starting materials. It characterizes, across large numbers of tumor samples or cell lines, the basal protein expression levels, growth factor- or ligand-induced effects, and time-resolved responses appropriate for systems biology analysis. It provides information to integrate the consequence of genetic aberrations in cancer, to validate therapeutic targets, to demonstrate on- and off- target activity of drugs, and to evaluate drug pharmacodynamics. We have defined a set of standard lysates to be used in each array for quality control of data generation and analysis.

27 The objective of this workshop is to provide a basic overview of the tools and methods used by computational biologists to analyze large- scale genomic datasets from human cancer patients. We will discuss next-generation sequencing methods including genome sequencing(DNA-seq) and transcriptome sequencing (RNA-seq). Next we will cover tools used for detecting structural variants, copy number changes and somatic mutations. We will then provide an overview of the ongoing large-scale genomic sequencing projects such as the Cancer Genome Atlas (TCGA) and the International Cancer Genome Consortium (ICGC) and how to access data from these projects using COSMIC and cBIO. We will also discuss how to distinguish driver from passenger mutations using prediction algorithms and mutation frequency. The topic of intratumor heterogeneity will also be discussed and how clonal diversity can affect the analysis of next-generation sequencing data. We will also cover data visualization tools including the Integrated Genome Viewer (IGV) and basic bioinformatics methods in multivariate statistics. Common programming languages and operating systems used by computational biologists will also be covered. Finally, we will discuss advanced courses offered at different institution that can be used to seek further training in computational biology, including the Cold Spring Harbor Laboratory (CSHL), the European Molecular Biology Laboratory (EMBL) and the Sanger Institute.

I specifically enjoy applying imaging techniques to solve problems. Specifically, my interest is protein trafficking.

29 Mass Cytometry is a burgeoning field where two very different technologies meet, Flow Cytometry and ICP-Mass Spec. DVS Sciences has developed an instrument based on an ICP-Mass Spec capable of performing flow cytometry measurements in an environment without spectral overlap and autofluorescence, thus removing the need for compensation. As such this new system alleviates the limitations of fluorescent based flow cytometry creating a paradigm shifting new instrument capable of up to 100 parameters per cell. Current limitations are ~35 parameters per cell. This instrument, called a CyTOF, utilizes unique metal isotopes (non-radioactive) as tags attached to antibodies to label your favorite proteins of interest. This results in Massively High Parametric data per cell which is then analyzed with SPADE Analysis. The limitations and benefits of the instrumentation will be discussed with some example preliminary datasets. Mass cytometry Session 3. Cytometry by Time-of-Flight (Cy-TOF)

Notable Honors/Awards: 2000-Present Guest Professorship, Shandong University Pre-Doctoral Fellowship, Austria National Science Foundation Research Interest: Our research interest is to identify ncRNA biomarkers for cancer early stage detection and diagnosis, later stage prognosis and therapeutic targets collaboratively using ultra-throughput and cutting-edge genomic technologies of microarray and next generation sequencing. As a centralized sequencing and ncRNA Core services, our primary responsibility is to provide NGS sequencing and ncRNA services support to Investigators and facilitate cancer research. In addition, we do collaboration with investigator for in-house developments of new methodology and applications using in-house existing technology and expertise. Our previous collaborative efforts of microRNA in cancer have resulted in over hundreds of scientific research papers.

31 The technologies of microarray and next generation sequencing enable us to analyze the changes of entire human genome and transcriptome in one single experiment. Data analysis has indicated more than 80% of human non-coding genome is transcribed into non- coding RNA (ncRNA). ncRNA includes large and small ncRNA that transcribed from the genomic regions of intronic, intergenic, antisense, interleaved, and overlapping with protein-coding genes. Given evidences have revealed the crucial and critical rules of miRNA, one class of ncRNA, expression in regulation of crucial processes of normal development, cell proliferation, apoptosis, differentiation and metabolism. Recent studies have identified different miRNA expression signature patterns, by miRNA expression profiling, associate with diagnosis and prognosis in human cancers and revealed abnormal miRNA expression modulates a wide array of growth and differentiation processes in human cancers. To explore more about non-coding RNAs involved in cancer and expand our concept in cancer genomic research, we have established a complete and comprehensive analytical system to study ncRNA in cancers at MD Anderson Cancer Center. This system includes 1) SOLiD™5500XL ultra-throughput genome system for novel ncRNA discovery and global profiling; 2) Ion Torrent PGM for targeted cancer related genes; 3) in-house custom miRNA/ncRNA expression array for all known targeted ncRNA expression profiling in cancer; 4) identification of miRNA/ncRNA and target mRNA interaction experimentally using NGS and Affymetrix mRNA profiling system besides computing prediction and 5) the correlation studies of differentially expressed ncRNA to it genomic copy number change by using NGS and array CGH assays. These combined approaches will allow us to gain full picture of cancer genomics and its differentially expressed noncoding RNA as biomarkers.

33 The Small Animal Imaging Facility (SAIF) is an core resource at The University of Texas MD Anderson Cancer Center. It was established to ensure that cancer researchers, regardless of their academic training, have access to cutting-edge imaging technologies and to the expertise that is necessary for their successful integration into routine cancer research. SAIF consists of instrumentation, specially trained staff, faculty affiliates with academic focus in imaging sciences, and infrastructure that facilitates data management and scheduling of services. Services include magnetic resonance imaging and spectroscopy, nuclear imaging, x-ray computed tomography, image-guided radiation therapy, ultrasound, photoacoustic, and optical (fluorescence/bioluminescence) imaging. Faculty and staff are available for consultation through all phases of research, from preliminary estimation of feasibility, through experiment design, data acquisition, analysis, and interpretation, and summary of results in grants, manuscripts, progress reports, and other media. SAIF is a fee- for-service facility with fees that compare favorably with similar preclinical/translational imaging cores at other institutions. Dedicated staff can carry out all aspects of imaging experiments, or users can be trained to operate SAIF instrumentation for self-directed imaging services. Recent advances in imaging technologies inform on the structure, function, and composition of tissue and disease with unprecedented specificity and resolution, and the Small Animal Imaging Facility is an efficient conduit for the integration of emerging imaging sciences into cancer research.
