Systemic analysis of available large-scale biological/biomedical data is critical for studying biological mechanisms, and developing novel and effective treatment approaches against diseases. However, different layers of the available data are produced using different technologies and scattered across individual computational resources without any explicit connections to each other, which hinders extensive and integrative multi-omics-based analysis. We aimed to address this issue by developing a new data integration/representation methodology and its application by constructing a biological data resource. CROssBAR is a comprehensive system that integrates large-scale biological/biomedical data from various resources and stores them in a NoSQL database. CROssBAR is enriched with the deep-learning-based prediction of relationships between numerous data entries, which is followed by the rigorous analysis of the enriched data to obtain biologically meaningful modules. These complex sets of entities and relationships are displayed to users via easy-tointerpret, interactive knowledge graphs within an open-access service. CROssBAR knowledge graphs incorporate relevant genes-proteins, molecular interactions, pathways, phenotypes, diseases, as well as known/predicted drugs and bioactive compounds, and they are constructed on-the-fly based on simple non-programmatic user queries. These intensely processed heterogeneous networks are expected to aid systems-level research, especially to infer biological mechanisms in relation to genes, proteins, their ligands, and diseases.

Suggestions

Network structure based pathway enrichment system to analyze pathway activities
Işık, Zerrin; Atalay, Mehmet Volkan; Atalay, Rengül; Department of Computer Engineering (2011)
Current approaches integrating large scale data and information from a variety of sources to reveal molecular basis of cellular events do not adequately benefit from pathway information. Here, we portray a network structure based pathway enrichment system that fuses and exploits model and data: signalling pathways are taken as the biological models while microarray and ChIP-seq data are the sample input data sources among many other alternatives. Our model- and data-driven hybrid system allows to quantitati...
Voxel-MARS: a method for early detection of Alzheimer's disease by classification of structural brain MRI
Cevik, Alper; Weber, Gerhard-Wilhelm; Eyüboğlu, Behçet Murat; Oguz, Kader Karli (2017-11-01)
Neuroscience is of emerging importance along with the contributions of Operational Research to the practices of diagnosing neurodegenerative diseases with computer-aided systems based on brain image analysis. Although multiple biomarkers derived from Magnetic Resonance Imaging (MRI) data have proven to be effective in diagnosing Alzheimer's disease (AD) and mild cognitive impairment (MCI), no specific system has yet been a part of routine clinical practice. This paper aims to introduce a fully-automated vox...
RANKPCSF: A DISEASE MODULE IDENTIFICATION METHOD BY INTEGRATING NETWORK PROPAGATION WITH PRIZE-COLLECTING STEINER FOREST
Eskin, Arda; Otlu Sarıtaş, Burçak; Tunçbağ, Nurcan; Department of Bioinformatics (2022-9-2)
Identification of disease modules may lead to a better understanding on the progression of diseases, finding more accurate biomarkers, and drug targets. In this study, we develop a hybrid method – RANKPCSF- combining the strength of Steiner tree and diffusion approaches and release a new network reconstruction approach. RANKPCSF is capable to integrate multi-omic data (including phosphoproteomic and transcriptomic) with a reference interactome to unveil the optimal disease-associated network. We have compar...
Autotelic personality : links with flow propensity, personal strengths, and psychopathology
Yarar, Orhan Ferhat; Bozo Özen, Özlem; Department of Psychology (2015)
The aim of the present doctoral dissertation is to infuse positive psychology research with clinical psychology for contributing to the development of a well balanced view of human psychic phenomenon, eventually leading to a shift in clinical research from disease models to a strength based one. For this purpose, life meaning, subjective happiness, curiosity, and flow propensity was investigated in terms of their associations with a newly developed positive constellation of autotelic personality traits. Bes...
Workshop on Large-Scale and Distributed Systems for Information Retrieval (LSDS-IR 2014)
Altıngövde, İsmail Sengör; Macdonald, Craig; Tonellotto, Nicola (2014-01-01)
The LSDS-IR'14 workshop aims to bring together information retrieval practitioners from industry and academic researchers concerned with efficient and distributed IR systems. The workshop also welcomes contributions that propose different ways of leveraging diversity and multiplicity of resources available in distributed systems. The main goal of the workshop is to attract people from industry and academia to present and discuss ideas, problems, and results related to the efficiency of large scale and distr...
