Sequencing and Analysis of the Hydra Genome
Chapman, Kirkness et al., Nature
An international research collaboration reports their sequencing and analysis of the Hydra magnipapillata genome, and compare it to the genomes of several other organisms. "The Hydra genome has been shaped by bursts of transposable element expansion, horizontal gene transfer, trans-splicing, and simplification of gene structure and gene content that parallel simplification of the Hydra life cycle," the authors write. They team suggests that comparisons of the Hydra genome to the reported sequences of other animals have helped them to elucidate the evolution of several of the organism's characteristics.
AHRQ Report Finds 'Insufficient Evidence' Supporting Genetic Testing To Prevent Deep-Vein Thrombosis
The authors of the report recommend conducting randomized trials with "sufficiently large sample sizes and long-term follow-up," in addition to other types of research to determine whether genetic testing in patients with a history of blood clots improves outcomes and whether physicians should alter current treatment practices to adopt genetic testing for the prevention of deep-vein thrombosis.
