Project Title: Oligonucleotide-Selective Sequencing for Integrated and Rapid Cancer Genome Analy
Fiscal Year: 2015


DESCRIPTION (provided by applicant): Personalized cancer medicine involves identifying clinically actionable cancer mutations and genomic aberrations in any given tumor. As we recently published in the November 2011 issue of Nature Biotechnology, Oligonucleotide-Selective Sequencing (OS-Seq) is a novel targeted resequencing approach that fundamentally improves the detection of cancer mutations from clinical samples. This technology has the potential for enabling the rapid, accurate detection of cancer mutations for both translational research studies and potentially, "personalized" cancer diagnostics. OS-Seq provides a number of advantages to make personalized cancer analysis accessible, rapid, robust and accurate. The overall workflow is simplified such that the majority of preparative steps take place on a standard fluidics device and the actual experimental manipulation is limited. The performance is improved compared to the current commercially available methods for targeted, gene-specific cancer sequencing analysis. Based on our empirical analysis and subsequent refinements in designing capture probes, we demonstrate very specific capture of genomic targets with less variance than other methods. We achieve a high level of sequencing coverage on our targets that permit sensitive and specific detection of cancer mutations. With recent improvements in sequencing technology speed, OS-Seq can potentially be adapted to analyze large number of cancer genes in a matter of days which includes the time that genomic DNA is extracted from a biopsy to the completion of the targeted sequencing run. This holds the possibility of rapidly identifying cancer mutations from clinical samples. Our proposal is focused on development of the OS-Seq technology for identifying cancer mutations, rearrangements, copy number alterations and potential cancer-related infectious agents from clinical tumor samples. To achieve this goal, we will develop key aspects of OS-Seq technology for integrated detection of cancer mutations and genomic aberrations with simple protocols that are reliable, rapid and with high accuracy.
