The snail (Biomphalaria glabrata) genome project

In 2001, ideas for a snail genome project were discussed at the American Society of Parasitologists meeting (New Mexico) and a snail genome consortium was subsequently established (the first consortium meeting was held in 2005). A proposal for sequencing the snail genome was submitted to the National Human Genome Research Institute, and Biomphalaria glabrata was prioritized as a non-mammalian sequencing target in 2004. The sequencing of the genome of this medically important snail is now underway.     

Public sphere and the sustainability of the bioinformatics promise

The literature about genomics and bioinformatics achievements in high-impact journals such as Nature and Science has raised disproportionate expectations amongst the general public about fast and revolutionary drugs and breakthroughs in biomedicine. However, the yield obtained by database mining activities has been modest, as reported in the February 2001 issues of these journals featuring the completion of human genome draft sequences by the Human Genome Project Consortium and the company Celera. I have compared changes in rethoric employed by molecular biologists in 2001 and in April 2003, when the final sequence was announced. The comparison suggests that researchers are concerned about the sustainability of society's investment in this field, though not explicitly.     

The Map Problem: A Comparison of Genetic and Sequence-Based Physical Maps

The genetic order of autosomal genome-scan markers from Marshfield panels 9 and 10 were compared with their physical order, on the basis of the assembled nonredundant human genome sequence from the Human Genome Project-Santa Cruz (HGP-sc; October 2000 and April 2001 releases) and Celera (CEL; February 2001 release) databases. The genetic order of 96% of the markers on the Marshfield map for panel 10 is supported by a likelihood ratio of > or = 3 (odds ratio of 1,000:1). Inconsistencies with the genetic panel 10 map were found for 5% and 2% of the markers in the CEL and HGP-sc sequences, respectively. These inconsistencies consisted of both positional and chromosomal-assignment disagreements. For the majority of these inconsistent markers, the genetic order was supported by a likelihood ratio of > or = 3, and the physical order in the other assembly matched the genetic order. The majority of the inconsistencies between the physical- and genetic-map order point to errors in the physical-map order. A Web site is made available that displays inconsistencies for genetic markers from Marshfield panels 9 and 10 between their genetic-map positions and sequence-based physical-map positions, as well as inconsistencies between their sequence-based physical position. This Web site also contains genetic-map distances, physical-map positions from the Celera and Human Genome Project sequence, and likelihood-ratio support for the genetic maps.     

Human genome diversity: what about the other human genome project?

Although the Human Genome Project has been successful, the Human Genome Diversity Project, proposed in 1991, has so far failed to thrive. One of the main values in studying the human genome, however, will come from examining its variations and their effects. To do that in a systematic way, an active Human Genome Diversity Project, or something very similar, will ultimately prove vital. Such an effort will confront difficult ethical and political issues; this article reviews those issues and tries to show how they might be overcome.

Misunderstandings about isochores. Part 1

A few months ago the International Human Genome Sequencing Consortium (IHGSC) published a 61-page paper on the human genome (IHGSC, Nature 409 (2001) 860). Here comments will be presented on some points of the paper that were previously investigated in our laboratory, and some misunderstandings and misconceptions about the organization and the evolutionary history of the human genome will be discussed. A very recent article on the same subject (Eyre-Walker and Hurst, Nat. Rev. Genet. 2 (2001) 549) will also be addressed. The present paper is a complement to two review articles which were published last year (Bernardi, Gene 241 (2000) 3; Gene 259(1) (2000) 31).     

Societal and Medical Consequences of the Human Genome Project

The Human Genome Project is a US-based molecular biological project, the results of which are likely to be implemented on humans. The sociopolitical dimension of this is highly neglected. The aim of the conference was to fill this gap by drawing together scientists of natural and political sciences to discuss the consequences of the Human Genome Project across the disciplines.     

The Human Genome Diversity Project: past, present and future

The Human Genome Project, in accomplishing its goal of sequencing one human genome, heralded a new era of research, a component of which is the systematic study of human genetic variation. Despite delays, the Human Genome Diversity Project has started to make progress in understanding the patterns of this variation and its causes, and also promises to provide important information for biomedical studies.     

Automated DNA sequencing and the analysis of the human genome

The Human Genome Initiative is a complex, multifaceted, international effort to establish a massive data base of map and sequence information for humans and other organisms. The success of this initiative is dependent upon the development of new technologies for the analysis of genomes. In this paper, an overview of the Human Genome Initiative is presented, and the current status of efforts to automate large-scale DNA sequence analysis is reviewed.     

Development and application of genotyping technologies

With the completion of Human Genome Project,International HapMap Project and the publication of copy number variation in human genome,a great number of accurate,rapid,and cost-effective technologies for SNP analysis have been developed,promoting the research of the complex diseases.This article presents a review of widely used genotyping techniques,and the progress and prospect in the study of complex diseases in terms of the projects and achievements of Chinese National Human Genome Center at Shanghai(CHGC...     

Genomics and mapping of teleostei (bony fish)

Until recently, the Human Genome Project held centre stage in the press releases concerning sequencing programmes. However, in October 2001, it was announced that the Japanese puffer fish (Takifugu rubripes, Fugu) was the second vertebrate organism to be sequenced to draft quality. Briefly, the spotlight was on fish genomes. There are currently two other fish species undergoing intensive sequencing, the green spotted puffer fish (Tetraodon nigroviridis) and the zebrafish (Danio rerio). But this trio are, in many ways, atypical representations of the current state of fish genomic research. The aim of this brief review is to demonstrate the complexity of fish as a group of vertebrates and to publicize the 'lesser-known' species, all of which have something to offer.     

Trends in proteomics

Inside SMP proteomics: six years German Human Brain Proteome Project (HBPP) - a summary

In 2001, the German Federal Ministry of Education and Research (BMBF) initiated the National Genome Research Network (NGFN; www.ngfn.de) as a nation-wide multidisciplinary networking platform aiming at the analysis of common human diseases and aging. Within the NGFN the Human Brain Proteome Project (HBPP; www.smp-proteomics.de) focuses on the analysis of the human brain in health and disease. The concept is based on two consecutive steps: (i) Elaborating and establishing the necessary technology platforms. (ii) Application of the established technologies for research in Alzheimer's disease and Parkinson's disease. In the first funding period, HBPP1, running from 2001 to 2004, necessary technologies were established and optimized. In HBPP2, which started 2004 and will end in May 2008, the developed technologies are used for large-scale experiments, offering new links for disease related research and therapies. The following overview describes structure, aims and outcome of this unique German Brain Proteome Project.

DNA sequencing: bench to bedside and beyond

Fifteen years elapsed between the discovery of the double helix (1953) and the first DNA sequencing (1968). Modern DNA sequencing began in 1977, with development of the chemical method of Maxam and Gilbert and the dideoxy method of Sanger, Nicklen and Coulson, and with the first complete DNA sequence (phage ϕX174), which demonstrated that sequence could give profound insights into genetic organization. Incremental improvements allowed sequencing of molecules >200 kb (human cytomegalovirus) leading to an avalanche of data that demanded computational analysis and spawned the field of bioinformatics. The US Human Genome Project spurred sequencing activity. By 1992 the first ‘sequencing factory’ was established, and others soon followed. The first complete cellular genome sequences, from bacteria, appeared in 1995 and other eubacterial, archaebacterial and eukaryotic genomes were soon sequenced. Competition between the public Human Genome Project and Celera Genomics produced working drafts of the human genome sequence, published in 2001, but refinement and analysis of the human genome sequence will continue for the foreseeable future. New ‘massively parallel’ sequencing methods are greatly increasing sequencing capacity, but further innovations are needed to achieve the ‘thousand dollar genome’ that many feel is prerequisite to personalized genomic medicine. These advances will also allow new approaches to a variety of problems in biology, evolution and the environment.
