Genetic variation has been though to be responsible for the differences between people to metabolize certain drugs. The results of a recent study from the Karolinska Institutet in Sweden suggest that it may be even more complicated. Swedish reserchers have found that the body’s ability to break down medicines may be closely related to sunlight exposure and vitamin D, and thus may vary with the seasons. The study, published in the journal Drug Metabolism & Disposition, offers a completely new model to explain individual differences in the effects of drugs .
In January, we reported on the National Human Genome Research Institute (NHGRI) Vision to Move Genomic Medicine from Base Pairs to Bedside. Written by Eric D. Green, M.D., Ph.D., Director of the NHGRI, Mark Guyer, Ph.D., Director of the Division of Extramural Research and Acting Deputy Director of the NHGRI, and others at the NHGRI, the plan maps the next steps the field of genomic research must take to discover medical secrets hidden within the human genome and transfer them to physicians and patients .
Interestingly, the strategic plan really isn’t a strategic plan but a list of issues to be addressed. And on this note, Daniel MacArthur, a genomics researcher and author of Wired’s Genetic Future, found the NHGRI document frustrating to read :
… this is an impressive, worthwhile and highly readable piece of work, but one that ultimately feels unfinished. As research dollars begin to get tighter, there is an urgent need for an actual strategic plan for building the resources and tools required to make genomic medicine a reality within a realistic budget.
In other words: a specific NHGRI funding plan to overcome the issues. This could prove difficult in the current U.S. fiscal environment. Even though President Obama has resisted cuts to biomedical research funding in his 2012 budget proposal, the outlook isn’t bright. Decreasing NIH funding for short-range budget goals will disrupt five-year-long longitudinal studies make it impossible to start new research . Moreover, it will hurt U.S. standing as the world leader in biomedical advances.
A group of researchers led by scientists from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed a new technology that detects distinct genetic changes differentiating cancer patients from healthy individuals . The technology is described in a recent study published in the journal Genes, Chromosomes and Cancer and may one day serve as the basis for a cancer predisposition test.
Earlier this month, Indiana University announced a major commitment to research in one of healthcare’s most promising fields, personalized medicine. The Indiana Institute for Personalized Medicine will pursue genome-based and pharmacogenomics studies in cardiology, pediatrics, obstetrics and cancer, as well as other areas . The emergence of personalized medicine, which targets individualized treatment and care based on personal and genetic variation, is creating a thriving market. Indeed, the market for personalized medicine in the United States is $232 billion and is projected to grow 11% annually .
A new strategic plan from an arm of the National Institutes of Health envisions scientists being able to identify genetic bases of most single-gene disorders and gaining new insights into multi-gene disorders in the next decade. This should lead to more accurate diagnoses, new drug targets and the development of practical treatments for many who today lack therapeutic options, according to the plan from the National Human Genome Research Institute (NHGRI).
