Rutgers geneticist Tara Matise and her colleagues have produced a map that will help pinpoint the genes linked to such serious diseases as diabetes, high blood pressure and schizophrenia.
This linkage map is based on the amount of the interaction or recombination taking place among nearly 3,000 genetic markers whose positions are known. The markers used for the map are single-nucleotide polymorphisms (SNPs) – the variations of a gene that people may carry at one point on their DNA.
A paper describing the linkage map will appear in the August 2003 issue of the American Journal of Human Genetics and is currently available online. Matise is first author on the paper, with Assistant Professor Steven Buyske and graduate student Chunsheng He, both from Rutgers, The State University of New Jersey, also among the authors.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
