Genetic Engineering & Biotechnology News reports on growing role of molecular diagnosticsOctober 06, 2008Novel platform technologies and key advances in genomics are rapidly driving the development of molecular diagnostics, reports Genetic Engineering and Biotechnology News (GEN). The payoff for successful molecular diagnostic products can be significant as Kalorama Information predicts that this market currently exceeds $3.2 billion worldwide and will reach $5.4 billion in four years, according to an article in the October 1 issue of GEN. "Molecular diagnostic products are based on cutting-edge research in two of the most promising biotechnologies, genomics and proteomics. These novel tests also utilize sophisticated analytical techniques such as microarrays and mass spectrometry," notes John Sterling, Editor-in-Chief of GEN. "Molecular diagnostics are particularly applicable to the early detection of cancer." Affymetrix and Illumina have both created array-based products that enable high-speed analysis of DNA, RNA, and proteins as tools for disease research, drug development, and molecular tests. These gene-sequencing tools are being applied at an earlier stage.
Genetic tests can optimize drug therapy, and companion diagnostics are being touted as a method to better define a patient's need or predict clinical outcome from a specific drug. The FDA recently approved a HER-2 test from Invitrogen called Spot-Light that can be used to identify breast cancer patients who are candidates for treatment with Herceptin. In addition, data was recently presented showing the importance of testing for the K-ras gene to assess the clinical benefit of Erbitux for metastatic colorectal cancer. Of all the larger integrated healthcare companies, Roche has best executed the synergies of molecular diagnostics and biopharmaceuticals and is well positioned for the future with products in oncology and infectious disease. Its genetic tests include CYP450 for drug metabolism studies and HER-2 for use with tamoxifen therapy. Other companies covered in the GEN article include Myriad Genetics, Genomic Health, Genoptix, Luminex, Abbott Labs, Aureon, Autogenomics, Nanosphere, Navigenics, Osmetech, and Perlegen Sciences.

Breast cancer treatment resistance linked to signaling pathway Activation of the Src signaling pathway may cause resistance to standard medical treatment in some patients with breast cancer, and inhibition of this pathway holds the potential to overcome that resistance, according to data presented here at the American Association for Cancer Research Molecular Diagnostics in Cancer Therapeutic Development meeting. New HPV test for developing countries shows high accuracy in predicting cervical disease: Study A new HPV test developed by QIAGEN specifically for use in regions of the world with scarce resources is "substantially" more accurate in identifying women with cervical disease than the current methods (Pap testing and visual inspection) in these countries. Gene chip data improved therapy in some patients with incurable cancer Like many oncologists, Eric P. Lester, M.D., was faced with a dilemma: seven patients with advanced, incurable cancer, an arsenal of drugs that may or may not help them, and not enough solid proof about treatment efficacy to guide him. To evade chemotherapy, some cancer cells mimic stem cells Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to findings presented today in Atlanta, Georgia at the American Association for Cancer Research's second International Conference on Molecular Diagnostics in Cancer Therapeutic Development. Gene profiling can single out the worst cases of multiple myeloma and guide therapy Multiple myeloma patients vary widely in how they respond to treatment, but now researchers at the Myeloma Institute for Research and Therapy at the University of Arkansas for Medical Sciences have identified a small subset of genes whose activity could predict high-risk cases and potentially guide therapy in the future. Test for lung cancer looks for discomforting quiet among protective genes When it is quiet - "almost too quiet" - in movies, it is a sign that something is about to go wrong for the good guys. Liver cancer marker could yield blood test for early detection In the face of an emerging liver cancer crisis in Asia, researchers at the Chinese University of Hong Kong have developed a test that could help millions. New technique can be breakthrough for early cancer diagnosis Early detection of disease is often critical to how successful treatment can be. Therefore, the development of new methods of diagnosis is a hot research field, where every small step is of great importance. In an article in the latest issue of Molecular & Cellular Proteomics, Uppsala University researchers describe a technique that the journal regards as especially interesting.
