Integrated analysis of homozygous deletions, focal amplifications, and sequence alterations in breast and colorectal cancers

we have performed a genome-wide analysis of copy number changes in breast and colorectal tumors using approaches that can reliably detect homozygous deletions and amplifications. We found that the number of genes altered by major copy number changes, deletion of all copies or amplification to at least 12 copies per cell, averaged 17 per tumor…. [Read More]

Identification and Localization of Myosin Superfamily Members in Fish Retina and Retinal Pigmented Epithelium

Myosins are cytoskeletal motors critical for generating the forces necessary for establishing cell structure and mediating actin-dependent cell motility. In each cell type a multitude of myosins are expressed, each myosin contributing to aspects of morphogenesis, transport, or motility occurring in that cell type. To examine the roles of myosins in individual retinal cell types,… [Read More]

The Genomes On Line Database (GOLD) in 2009: status of genomic and metagenomic projects and their associated metadata

The Genomes On Line Database (GOLD) is a comprehensive resource for centralized monitoring of genome and metagenome projects worldwide. Both complete and ongoing projects, along with their associated metadata, can be accessed in GOLD through precomputed tables and a search page. As of September 2009, GOLD contains information for more than 5800 sequencing projects, of… [Read More]

Complete genome sequence of Halogeometricum borinquense type strain (PR3(T))

Halogeometricum borinquense Montalvo-Rodriguez et al. 1998 is the type species of the genus, and is of phylogenetic interest because of its distinct location between the halobacterial genera Haloquadratum and Halosarcina. H. borinquense requires extremely high salt (NaCl) concentrations for growth. It can not only grow aerobically but also anaerobically using nitrate as electron acceptor. The… [Read More]

The integrated microbial genomes system: an expanding comparative analysis resource

The integrated microbial genomes (IMG) system serves as a community resource for comparative analysis of publicly available genomes in a comprehensive integrated context. IMG contains both draft and complete microbial genomes integrated with other publicly available genomes from all three domains of life, together with a large number of plasmids and viruses. IMG provides tools… [Read More]

IMG ER: a system for microbial genome annotation expert review and curation

MOTIVATION: A rapidly increasing number of microbial genomes are sequenced by organizations worldwide and are eventually included into various public genome data resources. The quality of the annotations depends largely on the original dataset providers, with erroneous or incomplete annotations often carried over into the public resources and difficult to correct. RESULTS: We have developed… [Read More]

Anatomy and development of the nervous system of Nematostella vectensis, an anthozoan cnidarian

Nematostella vectensis, an anthozoan cnidarian, whose genome has been sequenced and is suitable for developmental and ecological studies, has a complex neural morphology that is modified during development from the larval to adult form. N. vectensis’ nervous system is a diffuse nerve net with both ectodermal sensory and effector cells and endodermal multipolar ganglion cells…. [Read More]

Genome, transcriptome, and secretome analysis of wood decay fungus Postia placenta supports unique mechanisms of lignocellulose conversion

Brown-rot fungi such as Postia placenta are common inhabitants of forest ecosystems and are also largely responsible for the destructive decay of wooden structures. Rapid depolymerization of cellulose is a distinguishing feature of brown-rot, but the biochemical mechanisms and underlying genetics are poorly understood. Systematic examination of the P. placenta genome, transcriptome, and secretome revealed… [Read More]

Arachnid relationships based on mitochondrial genomes: asymmetric nucleotide and amino acid bias affects phylogenetic analyses

Phylogenetic analyses based on mitochondrial DNA have yielded widely differing relationships among members of the arthropod lineage Arachnida, depending on the nucleotide coding schemes and models of evolution used. We enhanced taxonomic coverage within the Arachnida greatly by sequencing seven new arachnid mitochondrial genomes from five orders. We then used all 13 mitochondrial protein-coding genes… [Read More]
