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.
If It Makes You Feel Any Better, the Chairs Are Really Uncomfortable
The ASHG meeting is in full swing with sunburned scientists showing up to give their talks and everyone getting adjusted to local time here in Hawaii. (Yep, Daily Scan's on the scene.) This week, attendees got caught up on what the 1,000 Genomes project is up to — the University of Oxford's Gil McVean said to keep an eye out for data from the initiative's pilot studies in November or December. Also, Elaine Mardis discussed work on cancer genome sequencing, particularly a breast cancer quartet study, and Pardis Sabeti focused on how to search the genome for signals of natural selection, among others.
Later, ASHG president Ed McCabe spoke about the interesting hypothesis that perhaps dogs domesticated humans. Really, he says that it was more similar to co-evolution, but it's fun to think about Rover instilling in us a need to throw tennis balls around the yard.
Cancer genomics took center stage yesterday as Gaddy Getz discussed the role of next-generation sequencing in understanding cancer, replacing arrays and capillary sequencing. Then, UCLA's Stan Nelson went over his universal aligner tool, BFast.
Oxford's Peter Donnelly cited his recent work with the Wellcome Case Control Consortium when he discussed the need to be vigilant in analyzing copy number variation data – an interesting CNV on chromosome 5 on the reference genome turned out to really be on the X chromosome, accounting for the effect they saw in female study participants. In another session, Steve Scherer went over the CNVs implicated in autism spectrum disorders.
