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.
PMC Issues White Paper to Help FDA Update Outdated Rx/Dx Co-development Concept Paper
The PMC's main recommendation is for the FDA to outline areas where regulatory flexibility and alternative clinical trial models are needed to account for the variety of drug/diagnostic development scenarios that can arise.
