Frost: “The Road Not Taken” Need to be able to recognize a specific location on the genome. Genome Editing Using Nucleases Existing approaches have been very challenging DNA-binding proteins such as “zinc fingers” and “TALEs” are difficult to tailor to recognize new DNA sequences Using yogurt bacteria to repair genetic mutation Developing CRISPR into a therapeutic agent Direct administration to specific disease tissue to mediate therapeutic gene modification. Ran et al., in preparation New Therapies (example HIV) Introduce protective mutations (e.g. treating HIV by removing the CCR5 gene) Future Challenges Facing CRISPR as a Therapeutic Technology CRISPR is still a very new technology - Development of effective delivery systems - Careful evaluation of safety, efficacy - Establishing thoughtful regulations that will enable technological advancement Genome Engineering RESOURCES http://www.genome-engineering.org 1400 1200 1000 800 600 400 Unique Visits Unique 200 0 Collaborators Luciano Marraffini Osamu Nureki Hiroshi Nishimasu Phil Sharp Xuebing Wu Rudolf Jaenisch Haoyi Wang Yi Zhang Azusa Inoue Shogo Matoba Genome Perturbation Platform David Root John Doench Ella Hartenian NIH Pioneer and TR01 awards, NSF, Keck, Gates, McKnight, Klingenstein, Merkin, Vallee, and Damon Runyon Foundations; Bob Metcalfe, and Jane Pauley zlab.mit.edu .
