Building systems-level views of genomes and disease Goal: A systems-level understanding of genomes and gene regulation: • The regulators: Transcription factors, microRNAs, sequence specificities • The regions: enhancers, promoters, and their tissue-specificity The targets: TFs targets, regulators enhancers, enhancers genes • The grammars: Interplay of multiple TFs prediction of gene expression • The parts list = Building blocks of gene regulatory networks Our tools: Comparative genomics & large-scale experimental datasets. • Evolutionary signatures for coding/non-coding genes, microRNAs, motifs • Chromatin signatures for regulatory regions and their tissue specificity Activity signatures for linking regulators enhancers target genes • • Predictive models for gene function, gene expression, chromatin state Integrative models = Define roles in development, health, disease
Challenge: interpreting disease-associated variants Gene annotation Roles in gene/chromatin regulation (Coding, 5’/3’UTR, RNAs) Activator/repressor signatures Evolutionary signatures CATGACTG CATGCCTG Disease-associated Non-coding annotation Other evidence of function variant (SNP/CNV/…) Chromatin signatures Signatures of selection (sp/pop) • GWAS, case-control,… reveal disease-associated variants Molecular mechanism, cell-type specificity, drug targets • Challenges towards interpreting disease variants – Find ‘true’ causative SNP among many candidates in LD – Use ‘causal’ variant: predict function, pathway, drug targets – Non-coding variant: type of function, cell type of activity – Regulatory variant: upstream regulators, downstream targets • This talk: genomics tools for addressing these challenges
Goal: Towards personal systems genomics Family Inheritance Recombination breakpoints Me vs. my brother My dad Mom’s dad Dad’s mom Human ancestry Disease risk Genomics: Regions mechanisms drugs Systems: genes combinations pathways
