Gurinder Singh “Mickey” Atwal (Cold Spring Harbor Lab, U.S.A.)

Short bio

Fueled by massive amounts of data generated from DNA sequencing technologies, the Atwal Lab is currently focused on population genetics, cancer biology and high-performance computing. We often tackle scientific questions computationally by invoking theoretical concepts from statistical physics and machine learning.
A common thread in our research is the quest to understand collective biological phenomena from the perspective of the physical sciences. To this end, we develop and deploy mathematical and computational tools to address quantitative principles governing the behavior of many-body biological systems, ranging from molecular interactions in a single eukaryotic cell to the evolution of the species Homo sapiens.Our fantastic team of lab members and collaborators consists of physicists, biologists, mathematicians and computer scientists and we work closely with experimentalists and clinicians both here at Cold Spring Harbor Laboratory and around the world.

Lecture outline

Cancer evolution is a stochastic evolutionary process characterized by the accumulation of mutations and responsible for tumor growth, clinical progression, immune escape, and drug resistance development. Evolutionary theory can be used to describe the dynamics of tumor cell populations and to make inference about the evolutionary history of a tumor from molecular profiling data. We discuss recent approaches to modeling the evolution of cancer, including population genetics models of tumorigenesis, phylogenetic methods of intra-tumor subclonal diversity, and probabilistic graphical models of tumor progression. Evolutionary modeling will play an increasingly important prognostic role in predicting disease progression and the outcome of medical interventions, such as targeted therapy.

Francesca Ciccarelli, King’s College (London, U.K.)

Short bio

Francesca Ciccarelli graduated in pharmaceutical chemistry at the University of Bologna and was trained as a computational biologist at the EMBL-Heidelberg. Her early work focused on DNA and sequence analysis and phylogenetic reconstructions. In 2005, she started her group at the European Institute on Oncology in Milan with the aim to elucidate the role of mutations in the development of cancer. Her group applies a combination of experimental and in silico approaches and pursues two main lines of investigation. The first aims at characterizing the systems-level properties of cancer genes and to use them to identify novel targets for therapy. The second line involves extensive cancer genome sequencing to characterize the evolution of cancer clones. In 2014, she moved to London as an Associate Professor at the King’s College School of Medicine.

Lecture Outline

In my lectures I will discuss on the recent advances in on our understanding of cancer genetics and evolution. I will start by reviewing the accumulating evidence of cancer heterogeneity in terms of acquired genetic mutations and genomic rearrangements. I will then describe the impact of these novel results on our modelling of cancer networks. Finally, I will describe how the characterization of cancer driver genes in terms of network can help in identifying cancer-specific targets to be used in therapy.

Cancer: From Endless Complexity to Simplicity (Introductory Lecture)

Cancer biologists have been celebrating the powers of reductionist molecular biology and its major successes for four decades. Many of those who have participated in cancer research during this period have witnessed wild fluctuations from times where endless inexplicable phenomenology reigned supreme to periods of reductionist triumphalism. However, the advent of massive amounts of -omics data in recent years has tampered that enthusiasm and is pointing to a move back to confronting the endless complexity of this disease. We will discuss how this summer school may help us to create a roadmap for the next generation of analysis. Such a roadmap can be built on statistical inference from data, philosophical models of causality, mathematical basis of phenomenological models, bio-chemical frameworks for mechanistic models, logical approaches based on model checking and control-theoretic approaches to therapy design.

Causality and Cancer: Multiple Facets: (Sept 30 Lecture)

Existing techniques to reconstruct tree  or DAG models of progression for accumulative processes such as cancer, seek to estimate causation by combining correlation and a frequentist notion of temporal priority. In these lectures we define a novel theoretical framework to reconstruct such models based on the probabilistic notion of causation defined by Suppes, and extended by Skyrm, Dupre and Cartwright. This view of causality differs fundamentally from that based on correlation. We consider a general reconstruction setting complicated by the presence of noise in the data, owing to the intrinsic variability of biological processes as well as experimental or measurement errors. Our analysis suggests the applicability of the method on small datasets of real patients.


Victor Moreno, ICO (Barcelona, Spain)

Short bio

Dr. Moreno is Professor of Preventive Medicine and Director of the Cancer Prevention and Control Program at the Catalan Institute of Oncology-IDIBELL in Barcelona, Spain. He has been long experience in genetic and molecular epidemiology studies on CRC. He has designed and conducted several case-control studies on CRC and contributed to the identification of genetic susceptibility loci, and molecular mechanisms involved in CRC etiology and progression. He leads the Unit of Biomarkers and Susceptibility at ICO, with strong expertise in biostatistics and bioinformatics. His team has experience both in the design of epidemiological and clinical studies and in the analysis of omics data. In his most recent project, COLONOMICS, (www.colonomics.org) tumors and adjacent normal mucosa from a sample of 100 CRC patients have been extensively characterized at molecular level (gene expression, micro-RNA expression, methylation, genetic variation, CNVs and somatic mutations in exome). Also samples of normal mucosa from 50 healthy donors have been analyzed. This resource is the bases for diagnostic and prognostic biomarker discovery and to elucidate the mechanisms involved using systems biology approaches.

Transcriptional regulatory programs of normal and tumor colon cells

Dysregulation of transcriptional programs leads to cell malfunctioning and can have an impact in cancer development. Within the COLONOMICS study (www.colonomics.org) we have characterized global differences between transcriptional regulatory programs of normal and tumor cells of the colon. Expression array data (Affymetrix Human Genome U219) from 100 samples of colon tumor and their paired adjacent normal mucosa were used to reconstruct. transcriptional networks. ARACNe algorithm was used to infer a consensus network for each cell type. Networks were compared regarding topology parameters and identified well-connected clusters, which were characterized by functional enrichment. ENCODE ChIP-Seq data curated in the hmChIP database was used for in silico validation of the most prominent transcription factors. A large loss of transcriptional interactions in the tumor network was observed, together with a subgroup of emergent or up-regulated transcription factors related to relevant colon cancer mechanisms. In a second analysis, microRNA data has been related to gene expression data to identify specific relevant regulatory clusters.
