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.
At Cold Spring Harbor Meeting, Next-Gen Sequencing Dominates Cancer Talks
In a session devoted to cancer genomics, groups from Washington University School of Medicine, the Wellcome Trust Sanger Institute, the Broad Institute, Baylor College of Medicine, the Ontario Institute for Cancer Research, and the Johns Hopkins Kimmel Cancer Center presented initial results from next-gen cancer sequencing projects and mentioned some of the challenges they have encountered in interpreting the data.
