Such net works help us identify major TFs and TF-gene relationships that underlie e xpression changes in the system being studied. Frequently\, GRN reconstruc tion methods exploit correlations in expression data and in many cases the y also utilize genome-wide TF-DNA binding and epigenomic profiles. Our rec ent research on this problem addresses two important challenges: (a) how t o integrate multiple types of data pertaining to TF-gene relationships\, d uring GRN reconstruction\, and (b) how to ‘enrich’ the reconstructed GRN w ith genes that underlie phenotypic variation among the samples. \n\nI will present the main underlying methodology\, based on probabilistic graphica l models\, and its application to two biological problems: (i) identifying TFs underlying drug response variation among individuals\, while integrat ing genotype\, TF-DNA binding\, DNA methylation\, gene expression and cyto toxicity data\, and (ii) identifying TFs underlying colorectal cancer prog ression from dynamic histone modification data as well as gene expression and TF-DNA binding data.\n DTSTART:20191029T160000Z DTEND:20191029T170000Z LOCATION:Room 1034\, McIntyre Medical Building\, CA\, QC\, Montreal\, H3G 1 Y6\, 3655 promenade Sir William Osler SUMMARY:QLS Seminar - Saurabh Sinha URL:/qls/channels/event/qls-seminar-saurabh-sinha-3017 02 END:VEVENT END:VCALENDAR
