ABSTRACT  Precision medicine is “using the best diagnostic results to make the best treatment for the patients”. In order to achieve the goal, we need the best tools for diagnosis, drug choice, and disease monitoring. As mentioned by the US President Barack Obama, these are “tools better predict which treatment will be most effective”. The basis of the best diagnostic results and treatment is everyone’s genome, and we must consider “individual differences in people’s genome, environments and lifestyles”. Recently, the improvement of next generation sequencing technologies makes the price sharply down to near 1000 US dollars for one human genome, and shortens the sequencing time to one human genome a day. These progresses make Precision Medicine become reality. Precision Medicine not only involves everyone’s personal genomic data, but also epigenome and other omics big data and many dynamic big data. How to integrate these big data to be used and to produce real-time actionable reports for physician is a very important issue, and we need to reconstruct the present medical information system to fulfill the goal.

From personal big data, we shall easily and precisely recognize a specific person and we can use this information to do a lot of activities. This may invade the privacy of human right. How to prevent it happen is also a very important issue. We propose a specific infrastructure which may solve these problems.

Big Data, Cyber Security, and Healthcare

Peter Pin-Shan Chen

Distinguished Career Scientist, Software Engineering Institute and CERT
Carnegie Mellon University, USA
ACM/IEEE/AAAS Fellow

ABSTRACT  Big Data and Cyber Security have attracted a lot of attention in healthcare and many other fields. In recent years, the amount of data has been increasing exponentially, almost to the level of unmanageable by the conventional relational database technology. Fortunately, new techniques and tools have been developed to “make sense” of the big data. On the other hand, big data has its own inherent problems such as security and privacy. It is more difficult to protect the security and privacy of big data than before. Almost every week, there is a news story about huge data sets were stolen from companies, medical institutions, and governments. On Dec 22, 2015, U.S. President Barack Obama signed into law a $1.1 trillion spending bill including the Cybersecurity Information Sharing Act (CISA). On February 9, 2016, President Obama proposed a $19 billion National Cybersecurity Action Plan (NCAP) outlining a grand plan to significantly improve the cybersecurity. All these indicate cybersecurity is a very important problem for not only the U.S. but all other countries in the world. Therefore, a question comes to mind: is big data a big mess, or a panacea? In this talk, we will focus on several more fundamental and critical issues of big data and its impacts on healthcare and the society.

ABSTRACT  Tumorigenesis can be regarded as an evolutionary process, driven by mutation and selection. Cancer genomics studies have provided tremendous amounts of data for addressing how cancer cells evolve.  To elucidate the underlying evolutionary process of cancer cell evolution, we have conducted three studies. (1) First, we addressed the question of “from the view point of the human protein-protein interaction network (PPI) where are cancer causal mutations more likely to occur in the PPI?” Are they much more likely to occur in hubs? Are cancer genes evolutionarily very ancient? (2) Is the DNA replication timing an important determinant of the somatic mutation rate? Is the mutation rate higher in late replication regions than in early replication regions? Are cancer driver genes more likely to locate in early replication regions? (3) Do tumor cells evolve by Darwinian (positive) selection, as commonly believed? And how much genetic diversity exists in a tumor? This question has important implications for cancer therapy. In my talk, I will present the above three studies.

Understanding and Interpreting Cancer Big Data by Supercomputer and Artificial Intelligence

Satoru Miyano

Director of Human Genome Center
University of Tokyo, Japan
ISCB Fellow

ABSTRACT  This lecture gives details of Genomon2 and our practices of a clinical cancer genome sequencing system with IBM Watson Genomic Analytics (WGA) at the Institute of Medical Science, The University of Tokyo (IMSUT). Genomon2 that is a suite of bioinformatics tools for analyzing cancer genomes and RNA sequencing data. It enables us to perform sensitive and accurate detection of most types of genomic variants (single nucleotide variants, short indels, mid-size indels and large scale structural variations), and transcriptomic changes (gene fusions, aberrant splicing patterns). It adopts an efficient job scheduling framework that enables us easily analyzing several hundreds of genome and transcriptome sequencing data simultaneously. Genomon2 is easy to install, and after installation, users can start analysis just preparing simple sample configuration files. The clinical cancer genome sequencing team has been using WGA at the research hospital of IMSUT since July of 2015. Genomon2 is used for genome sequence data analysis in this system for whole genome, whole exome, and panel. We show how WGA is used for clinical sequence for hematological malignancies and some solid tumors.

Improving Consistency and Coverage of MS-based Proteomics

Limsoon Wong

KITHCT chair professor
National University of Singapore, Singapore
ACM Fellow

ABSTRACT  Mass spectrometry (MS)-based proteomics is a widely used and powerful tool for profiling systems-wide protein expression changes. It can be applied for various purposes, e.g. biomarker discovery in diseases and study of drug responses.  Nonetheless, MS-based proteomics tend to have consistency issues (poor reproducibility and inter-sample agreement) and coverage issues (inability to detect the entire proteome) that need to be urgently addressed.  This talk discusses how these issues can be addressed by proteomic profile analysis techniques that use biological networks (especially protein complexes) as the biological context.  In particular, several techniques that we have been developing for complex-based analysis of proteomics profile are described. These techniques are useful in identifying proteomics-profile analysis results that are more consistent, more reproducible, more robust in the presence of batch effects, and more biologically coherent, and these techniques allow expansion of the detected proteome to uncover and/or discover novel proteins. Incidentally, I think this work beautifully demonstrates the triumph of logic and computational thinking over noise. (Joint work with Wilson Wen Bin Goh.)

On Mining Brain Networks

Philip S. Yu

UIC Distinguished Professor and Wexler Chair in Information Technology
University of Illinois at Chicago, USA
ACM/IEEE Fellow

ABSTRACT  In this talk, we examine some recent advances in mining brain network data to detect neurological disorder. Modern imaging techniques have allowed us to model the human brain as a network or graph. A brain connectivity network can be constructed from neuroimaging data, where the nodes of the network correspond to a set of brain regions and links represent the functional or structural connectivity between these regions. The linkage structure in brain networks can encode valuable information about the organizational properties of the human brain as a whole. As the functional connectivity among different brain regions is highly uncertain, each human brain needs to be represented as an uncertain graph, where the edges represent the probabilistic connections, e.g., resting-state functional connectivity in fMRI (functional Magnetic Resonance Imaging). Resting-state functional connectivity has shown alterations related to many neurological diseases, such as Bipolar, ADHD (Attention Deficit Hyperactivity Disorder), Alzheimer’s disease and virus infections that may affect the brain functioning such as HIV. We examine the challenges and advances in analyzing or mining the complex structure and uncertain connectivity of human brains to find biomarkers for neurological diseases. Such biomarkers are highly desirable to aid in the diagnosis, monitor disease progression and to evaluate treatment effect of new drugs and therapies. As measurements from a series of medical examinations are often available for each patient, including clinical, imaging, immunologic, serologic and cognitive measures, we further study how to combine all these features together in an effective way for disease diagnosis by exploring advances in multi-source learning.
