New research about human genetic diseases and human development

Friday, April 30, 2010 - 03:40 in Biology & Nature

The density of transposable (jumping) elements between sex chromosomes in primates may have important consequences for the studies of human genetic diseases, say Penn State University researchers. Erika Kvikstad, a 2009 Penn State Ph.D. graduate in genetics, and Kateryna Makova, an associate professor of biology at Penn State, used a statistical regression method to study the genomes of the human, chimpanzee, macaque, and orangutan, concluding that there is a strong sex-chromosome bias in the distribution of transposable elements, and providing insights about whether these non-coding, but important, DNA elements integrate themselves specifically into the male germline or female germline, or integrate themselves into the genome during the early stages of embryogenesis. Their study will be published in the May 2010 issue of the scientific journal Genome Research...
