Working with such huge number of genes is a complex process. So, our framework for inferring gene interactions from large scale microarrays is based on a selected set of informative genes. We applied two measures of dependencies between genes: Correlation and mutual information. Therefore, two types of networks were constructed: Co-expression network and Mutual information network. Some Mutual information network inference algorithms: Context Likelihood of Relatedness (CLR), Algorithm for the Reconstruction of Accurate Cellular Networks (ARACNE), and Minimum Redundancy Network (MRNET) were applied. A proposed method for simplifying the complex structure of the inferred network is introduced using the Minimum Spanning Tree (MST) which provides a better visual interpretation of the constructed networks. From the constructed networks we were able to identify a set of functional gene modules. These modules were validated using the Gene Ontology (GO) enrichment. The GO enrichment analysis has proven the strength of the ARACNE inference algorithm over all other employed algorithms. Moreover, a comparison was carried out between the Mutual information network inference and the well known Bayesian inference. To establish this comparison, specific pathways in HCC were rather chosen. These pathways were tested for their significance using singular value decomposition. According to this comparison, again the ARACNE showed better results.","PeriodicalId":109281,"journal":{"name":"2012 29th National Radio Science Conference (NRSC)","volume":"18 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113962372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The outcome of HCC patients still remains dismal due to the difficulty in detecting the disease at its early stage. We propose a new approach aiming to identify new biomarkers for early diagnosis of HCC. Genomic DNA copy number alterations (CNAs) are associated with complex diseases like HCC. Array-based Comparative Genomic Hybridization (a-CGH) is a technique used to identify copy number changes in genomic DNA. We use a statistical model based on a circular binary segmentation (CBS) algorithm. Our approach makes use of a median absolute deviation model to separate outliers from their surrounding segments. We tested 35 samples of HCC patients on specific chromosome regions, then applied CBS algorithm to detect genomic DNA alternations in copy number. Our results show that a gain of 1q was detected in 63% and a gain of 20q was detected in 26% of HCC cases. Also, a loss of 4q was detected in 3%, a loss of 13q was detected in 29%, loss in 16q was detected in 9%, and loss of 17q was detected in 3% of HCC cases.","PeriodicalId":109281,"journal":{"name":"2012 29th National Radio Science Conference (NRSC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125690493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
