Title of Lecture 1Discovery of mutateddriver pathways in cancer

Time2017-06-26 8:30-9:10

LecturerProf.Shihua Zhang

About the Lecture

    Large-scalecancer genomics projects are providing a large volume of data about genomic,epigenomic and gene expression aberrations in multiple cancer types. One of theremaining challenges is to identify driver mutations, driver genes and driverpathways promoting cancer proliferation and filter out the unfunctional andpassenger ones. In this talk, I will present a series of progresses about de novo mutated driver pathways or genesets identification from mutation data in cancer. Specifically, as to the so-calledmaximum weight submatrix problem, we first designed binary linear programmingmethod and genetic algorithm to solve it (MDPFinder). We further proposed anexact mathematical programming method denovo identify co-occurring mutated driver pathways (CoMDP) incarcinogenesis without any prior information beyond mutation profiles. Lastly,we proposed to computational methods to identify cancer common or specificmutated driver gene sets from mutation data of multiple cancers (ComMDP andSpeMDP). The efficiency of these methods were validated by testing on simulateddata. Tests on to several real biological datasets have been demonstrated toshow their effectiveness.

Title of Lecture 2Computational predictionof miRNA and miRNA-disease relationship

Time2017-06-26 9:10-9:50

LecturerProf.Quan Zou

About the Lecture

    microRNAis a kind of “star” molecular, and serves as a “director” since it can regulatethe expression of protein. In 2006, related works on gene silence won Nobelprice, which made miRNA be the hot topic in molecular genetics andbioinformatics. Mining miRNA and targets prediction are two classic topics incomputational miRNAnomics. In this talk, we focus on the miRNA mining problemsfrom machine learning views. We point out that the negative data is the keyproblem for decreasing the False Positive rather than exploring betterfeatures. miRNA-disease relationship prediction is another hot topic in recentyears. We introduce some novel network methods on calculating miRNA-miRNAsimilarity, which is the key issue for miRNA-disease relationship prediction. Someresults revealed that several novel miRNA could serve as the targets or markersfor some tumors.

Title of Lecture 3Predicting proteinsubmitochondrial locations: past, present and future

Time2017-06-26 9:50-10:30

LecturerProf.Pufeng Du

About the Lecture

    Predictingprotein subcellular location is a classical topic in bioinformatics. Predictingprotein submitochondrial locations goes one step further than the subcellularlocations. Over the past decades, we have carried out a serial of works inpredicting protein submitochondrial locations. In this talk, we will review thebiological fundamentals in predicting protein subcellular locations, introduceour works in predicting protein submitochondrial locations, and discuss the futuresin this research topics.

Profile of the Lecturer

    Dr.Pufeng Du received his bachelor degree and his Ph.D. from Tsinghua Universityin 2005 and 2010, respectively. During 2013 and 2014, he worked as a visitingpostdoc fellow in the City University of Hong Kong, supported by the HK ScholarProgram. He worked as an assistant professor in the School of Computer Scienceand Technology of Tianjin University from Jan. 2010 to Jun. 2013. He hasalready published over 30 academic papers, which have been cited for over 700times.

 

Title of Lecture 4Multi-label learning forprotein function prediction

Time2017-06-26 10:40-11:20

LecturerProf.Guoxian Yu

About the Lecture

    Proteinfunction prediction is one of key problems in Bioinformatics. Proteins oftenengages in different life process and can be annotated with differentfunctional labels. Current functional information of proteins have many missingannotations and some noisy annotations. In this lecture, I will first introducehow to model the complex protein function prediction task by multi-labellearning. Then, I introduce our progress on using multi-label weak-labellearning, multi-label partial label learning and structural functional labelsof Gene Ontology to replenish missing annotations, irrelevant annotations andnoisy annotations. In addition, we will also introduce our work on fusingmultiple data sources for protein function prediction.

Title of Lecture 5Network-based methods forpredicting disease associated genes, ncRNAs, and drugs

Time2017-06-26 11:20-12:00

LecturerProf.Min Li

About the Lecture

    Advancesin genome-scale molecular biology and molecular genetics have greatly elevatedour knowledge on the basic components of human diseases. Human diseases arealways caused by complex mechanisms involving aberrations in numerous proteinsand pathways. The increase in availability of genetics and molecular biologydata allowed describing human disease in terms of genes, non-coding RNAs anddrugs. Built upon these recent technological and conceptual advances,network-based approaches as powerful tools have been proposed to study humandiseases. For these network-based methods, each biological system is consideredas a network model, we try to elaborate how the molecules, the interactions andthe network structures determine the functions of biological systems, which canhelp us understand the cellular organizations, processes and functions. In thistalk, some of our works about predicting potential associations fordrug-target, drug-disease, miRNA-disease and lncRNA-disease are presented.These studies are commonly based on assumption that similar biological entitiestend to show similar interaction patterns, i.e a group of similar biologicalentities usually related with other class of similar biological entities.
