Short Abstract: Gene fusions are important in the initial steps of carcinogenesis, and represent a critical class of therapeutic targets. Based on NCIBI tools and technologies, we discovered several novel characteristics of gene fusions in human malignancies, and created an integrative Bioinformatics model for the translation of bio-data into novel gene fusions.

We analyze urinary metabolomic data to investigate important metabolites involved in cachexia, and predict cachectic status of patients.

Integrating large-scale data from splicing microarray experiments
Ana Rita Grosso- Institute of Molecular Medicine
Ines Mollet (Institute of Molecular Medicine, Cell Biology Unit); Maria Carmo-Fonseca (Institute of Molecular Medicine, Cell Biology Unit);
Short Abstract: Some of the splicing decisions occurring in specific physiological or pathological conditions are expected to be caused by differences in the concentration and/or activity of regulatory proteins. We have initiated a global meta-analysis that integrates data from microarray experiments in several cancer types making use of ExonMine database (http://www.imm.fm.ul.pt/exonmine).

Short Abstract: Cancer is a heterogeneous disease, but current therapies treat most patients similarly. Many groups seek to use mRNA signatures to personalize therapy. We demonstrate the network properties of effective prognostic signatures, relative to ineffective ones. We exploit the large I2D PPI database and develop a novel permutation analysis methodology.

Short Abstract: This poster will review the use of tissue expression profiles to prioritize disease candidate genes and illustrate these approaches with the prioritization of genetic risk factors for late-onset Alzheimer’s disease (LOAD) and Ataxia. The recent discovery of the P86L polymorphism in CALHM1 as a LOAD risk factor will be highlighted.

A 12-gene expression signature prognostic for squamous cell lung carcinoma

Short Abstract: We identified a 12-gene expression signature prognostic for squamous cell carcinoma of the lung based on goodness-of-fit (R square). The signature was validated in two independent microarray datasets. In addition, its superior performance over Raponi's original 50-gene signature and a newly publshed 50-gene signature was demonstrated by side-by-side comparison.

Shepherd (Ontario Cancer Institute, Princess Margaret Hospital, University Health Network, Department of Medical Oncology and Hematology); Ming-Sound Tsao (Princess Margaret Hospital, University Health Network, Ontario Cancer Institute); Igor Jurisica (Princess Margaret Hospital, University Health Network, Ontario Cancer Institute);
Short Abstract: Multiple prognostic gene-based classifiers for non-small cell lung cancer (NSCLC), with little overlap between gene sets, were used to generate protein interaction network from I2D database. This network is significantly more inter-connected compared to random networks, containing sets of “critical” nodes connecting multiple classifier-assigned proteins, linking pathways potentially underlying NSCLC.
