What is gene therapy?• Cells affected by diseases caused by “broken” genes can be aided
by the addition of “working” genes
• Working genes are carried by a vector, in most cases an altered virus, into an individual’s cells
• Working genes which are incorporated into the cell then produce their protein products, correcting the cell’s malfunction
• So cells will continue to create copies of inserted DNA, new gene needs to integrate into cell’s DNA– Altered retroviruses (disease-causing genetic material removed)
integrate their genetic material into the host organism’s
• Insertional mutagenesis-- Insertion disrupts DNA sequence and causes changes in nearby gene expression
WorkflowSeqMap Workflow
SeqMap: an automated tool
• Genes within 300kbp of the integration site are found using BLAT (BLAST-like alignment tool) on local copies of UCSC and Ensembl
• Functional analysis is provided by noting genes found in the Retroviral Tagged Cancer Gene Database (RTCGD) and associated Gene Ontology (GO) terms
SeqMap: genome mapping
Future
• Collect publicly available gene therapy data and incorporate into site– Working with Indiana University Vector
Production Facility to collect data
• Future additions to the SeqMap tool also include– analysis of functional annotations
