Mining gene expression profiles and gene regulatory networks: Identification of phenotype‐specific molecular mechanismsMining gene expression profiles and gene regulatory networks: Identification of phenotype‐specific molecular mechanisms Αφίσα σε Συνέδριο Conference Poster 2015-11-032008enThe complex regulatory mechanisms of genes and their transcription are the major gene regulatory steps in the cell. Gene Regulatory Networks (GRNs) and DNA Microarrays (MAs) present two of the most prominent and heavily researched concepts in contemporary molecular biology and bioinformatics. The challenge in contemporary biomedical informatics research lies in systems biology - the linking of various pillars of heterogeneous data so they can be used in synergy for life science research. Faced with this challenge we devised and present an integrated methodology that ‘amalgamates’ knowledge and data from both GRNs and MA gene expression sources. The methodology, is able to identify phenotype-specific GRN functional paths, and aims to uncover potential gene-regulatory ‘fingerprints’ and molecular mechanisms that govern the genomic profiles of diseases. Initial implementation and experimental results on a real-world breast-cancer study demonstrate the suitability and reliability of the approach.http://creativecommons.org/licenses/by/4.0/97-1095th Hellenic Conference of AI Proceedings Moustakis Vasilis Μουστακης Βασιλης Alexandros Kanterakis Dimitris Kafetzopoulos George Potamias Springer Verlag
