Next Generation Sequencing and Human Genome Databases
Genomics, Bioinformatics & Medicine I have been asked to speak to you about the impact that the human genome project will have on biomedical research and education. It is clear that the new fields of genomics and bioinformatics will have the same revolutionary effects on medicine as they have had on molecular biology and biomedical research. I would like to present you with a vision of that revolution and some of its implications for medicine and medical education in particular. I would first like to call your attention to some reference materials that can give you further background on these issues: Scientifc American Introduction to Molecular Medicine, just enough, BMA. Science Magazine features the Human Genome project, Lee Rowan (sequencing human genome), Phil Hieter on Understanding the Human genome, Joe Derisi, current graduate students (studying gene expression) MIS Short Course on Medical Informatics - you may see a videolectures here Doug Brutlag Professor Emeritus of Biochemistry & Medicine Stanford University School of Medicine
