The Gladstone <strong>Institute</strong>sIn 2009–2010, Gladstone scientists werechosen to lead or participate in majornationwide collaborations initiated by theNational <strong>Institute</strong>s of Health to acceleratetranslational research in several diseaseareas.The iPrEx study is a major internationaleffort to study whether a pill containinganti-HIV medications can preventacquisition of HIV using a conceptcalled pre-exposure prophylaxis orPrEP. Gladstone scientists, led byRobert Grant, are collaborating withscientists in Peru, Brazil, Ecuador,Africa, Thailand, and the U.S. onthis project. The primary analysisindicated that two oral antiretroviralagents, emtricitabine and tenofovir,decreased the acquisition of HIVinfection among men who have sexwith men by 44 percent overall, and73 percent among those who reportedtaking the pill consistently. The studyis being extended to learn how this newinformation about PrEP safety andefficacy might affect people’s use of thepills, and their sexual behavior. Theoriginal iPrEx study cost $43 millionand was sponsored by the U.S. NIH withco-funding from the Bill and MelindaGates Foundation and drug donatedby Gilead Sciences, representing apioneering partnership between public,charitable, and private agencies. TheNIH recently provided an $13 million toextend the study.Scientists at the Gladstone <strong>Institute</strong> ofNeurological Disease and its Taube-Koret Center for Huntington’s DiseaseResearch are leading a $3.6 millionconsortium to use stem-cell technologyto better understand Huntington’sdisease and to develop potentialtherapies. The consortium laboratoriesare located at the University ofWisconsin, Massachusetts GeneralHospital, UC Irvine, Johns Hopkins,and the Gladstone <strong>Institute</strong>s. Theresearchers will use induced pluripotentstem (iPS) cell technology, pioneeredby Gladstone and Kyoto University’sShinya Yamanaka, to develop humanneurons with Huntington’s diseasecharacteristics. iPS technologygenerates stem cells from adult skinsamples.The National Heart, Lung and Blood<strong>Institute</strong> (NHLBI) funds severalcollaborations studying heart diseaseand regenerative medicine. Forexample, scientists at the Gladstone<strong>Institute</strong> of Cardiovascular Disease andStanford University School of Medicinewill develop stem cell and regenerativemedicine therapies. Gladstoneinvestigators, led by Deepak Srivastavawill collaborate with a Stanford teamto determine how iPS cells can repairdamaged heart muscle. Each researchteam will receive approximately $10million.As part of NHLBI’s “Bench to Bassinet”program, Gladstone scientists willreceive $10 million over six yearsto find genetic causes of congenitalheart disease. The team, led by BenoitBruneau, focuses on the gene networksand regulatory factors related tocongenital heart defects. Cuttingedgegenome-mapping techniqueswill identify and define the functionof transcription factors with knownroles in cardiac development andhuman disease and so-called epigeneticregulators that open up chromosomesto allow access for transcription factors.<strong>California</strong> <strong>Biomedical</strong> <strong>Industry</strong> 2011 Report | 79
