A plan for the mouse genome project

The National Center for Human Genome Research and the Department of Energy convened a committee of geneticists and biologists who use the laboratory mouse in their research programs. Their responsibility was to identify goals and guidelines for completing the genetic and physical maps of the mouse genome. The motivation for convening this group was to make certain that existing and anticipated research projects together represent a comprehensive program for addressing the Five Year Goals of the Human Genome Project. Three meetings were held: the first addressed the contributions that the mouse can make to the Human Genome Project; the second meeting reviewed the status of the genetic map, gene mapping research, and genome informatics; and the final meeting evaluated the status of the physical map and physical mapping research. The committee then prepared a report that reviewed the status of the mouse genome project and made recommendations concerning areas of research emphasis. The resulting Request For Applications entitled Mapping the Mouse Genome with Emphasis on Technology Development (RFA: HG92-002) is an important mechanism for coordinating mouse genome research and accomplishing the goals of the mouse genome project. Progress towards complete genetic and physical maps has been impressive. The genetic map should be completed on schedule, and ongoing physical mapping projects are promising. Given rapid progress on these maps, the Working Group proposed expanding the focus of the mouse genome effort to begin planning comprehensive approaches for characterizing the function of the large number of genes that will soon be mapped and eventually sequenced. Partly as a consequence of the Working Group's efforts, discussions have begun among members of the scientific community and National Institutes of Health (NIH) staff to plan comprehensive, efficient, and innovative approaches for studying gene function. The Working Group prepared a report summarizing the status of mouse genome research and recommending areas where effort and funding should be placed. Our report was submitted to and accepted by the NIH and Department of Energy (DOE) and is published here in its entirety.Verne M. Champman, Chair, Neal G. Copeland, Franklin D. Costantini, William F.

Advances in the human genome project – A review

While celebrating its fifth official birthday last year it seems that the Human Genome Project (HGP) has and will continue to yield important biochemical information to mankind. It is exhilarating to think about the transition from studying genome structure to understanding genome function. The collective actions of information dessimination, technology development for efficient and faster sequencing, high-volume sequencing and developing model organisms has led to its success sofar. Various genome-wide STS-based human maps were completed in 1995, including a genetic map, a YAC map, a RH map with, and an integrated YAC-RH genetic map. These maps provide comprehensive frameworks for positioning additional loci, with the current genetic and RH maps spanning essentially 100% of the human genome and the YAC maps covering 95%. Few genes, however, have yet been localized on these framework maps. To date the Human Genome Project has experienced gratifying success. The technology and data produced by the genome project will provide a strong stimulus to broad areas of biological research and biotechnology. However, enormous challenges remain.     

人类变异组计划及其进展

基因组学构建了人类的基因组图谱,后基因组时代的主要任务是解释基因组如何影响生命活动,由此产生了各种新类型的组学:结构基因组学,功能基因组学,蛋白质组学,代谢组学等。人类基因组突变学会于2006年6月在澳大利亚的墨尔本会议上正式启动了人类变异组计划。该计划旨在全球范围内广泛收集所有基因和蛋白质序列变异和多态性的数据,采用全基因组级别的基因型与表型关联等方法,系统地搜索并确定与人类疾病相关的变异,以指导临床应用。鉴于该计划对人类健康领域将产生的潜在影响,文章较为全面地介绍了该计划的起源和主要内容,并对其意义和前景进行了讨论。     

Applications of the polymerase chain reaction to genome analysis

The objectives of the Human Genome Project are to create high-resolution genetic and physical maps, and ultimately to determine the complete nucleotide sequence of the human genome. The result of this initiative will be to localize the estimated 50,000-100,000 human genes, and acquire information that will enable development of a better understanding of the relationship between genome structure and function. To achieve these goals, new methodologies that provide more rapid, efficient, and cost effective means of genomic analysis will be required. From both conceptual and practical perspectives, the polymerase chain reaction (PCR) represents a fundamental technology for genome mapping and sequencing. The availability of PCR has allowed definition of a technically credible form that the final composite map of the human genome will take, as described in the sequence-tagged site proposal. Moreover, applications of PCR have provided efficient approaches for identifying, isolating, mapping, and sequencing DNA, many of which are amenable to automation. The versatility and power provided by PCR have encouraged its involvement in almost every aspect of human genome research, with new applications of PCR being developed on a continual basis.     

The human proteome project: current state and future direction

After the successful completion of the Human Genome Project, the Human Proteome Organization has recently officially launched a global Human Proteome Project (HPP), which is designed to map the entire human protein set. Given the lack of protein-level evidence for about 30% of the estimated 20,300 protein-coding genes, a systematic global effort will be necessary to achieve this goal with respect to protein abundance, distribution, subcellular localization, interaction with other biomolecules, and functions at specific time points. As a general experimental strategy, HPP research groups will use the three working pillars for HPP: mass spectrometry, antibody capture, and bioinformatics tools and knowledge bases. The HPP participants will take advantage of the output and cross-analyses from the ongoing Human Proteome Organization initiatives and a chromosome-centric protein mapping strategy, termed C-HPP, with which many national teams are currently engaged. In addition, numerous biologically driven and disease-oriented projects will be stimulated and facilitated by the HPP. Timely planning with proper governance of HPP will deliver a protein parts list, reagents, and tools for protein studies and analyses, and a stronger basis for personalized medicine. The Human Proteome Organization urges each national research funding agency and the scientific community at large to identify their preferred pathways to participate in aspects of this highly promising project in a HPP consortium of funders and investigators.     

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.     

The GDB Human Genome Data Base anno 1994.

In 1991 the Genome Data Base at Johns Hopkins University School of Medicine was selected as the central repository for mapping data from the Human Genome Project, and was funded by NIH and DOE under a three year award. GDB has now finished 28 months of Federally funded operation. During this period a great deal of progress and many internal changes have taken place. In addition, many changes have also occurred in the external environment, and GDB has adapted its strategies to play an appropriate role in those changes as well. Recognizing the central role of mapping information in the genome project, it is important that GDB respond aggressively to the increasing demands of genomic researchers, as well as formulate a program of response to a number of long standing, but still unmet, needs of that community. It is even more important that GDB provide leadership in the genome informatics enterprise. Three themes described here are dominant in our future plans and represent the essence of the major changes made in the past year. They include: enhanced data acquisition, better map representation, and full integration into the collection of genomic databases.     

A strategy for mapping the heterochromatin of chromosome 2 of Drosophila melanogaster

The heterochromatin of chromosome 2 of Drosophila melanogaster has been among the best characterized models for functional studies of heterochromatin owing to its abundance of genetic markers. To determine whether it might also provide a favorable system for mapping extended regions of heterochromatin, we undertook a project to molecularly map the heterochromatin of the left arm of chromosome 2 (2Lh). In this paper, we describe a strategy that used clones and sequence information available from the Drosophila Genome Project and chromosome rearrangements to construct a map of the distal most portion of 2Lh. We also describe studies that used fluorescent in situ hybridization (FISH) to examine the resolution of this technique for cytologically resolving heterochromatic sequences on mitotic chromosomes. We discuss how these mapping studies can be extended to more proximal regions of the heterochromatin to determine the structural patterns and physical dimensions of 2Lh and the relationship of structure to function.     

Genetics: the not-so-new new thing

Practical knowledge of heredity predates history. Indigenous peoples laid the foundations of modern agriculture by developing plants such as corn. However, the language and metaphors of the Human Genome Project treat modern genetics as if it had no historical antecedents and fail to acknowledge these early contributions to the science of heredity. The results of this blindness are twofold: it exacerbates reluctance of native peoples to take part in genetic research and to garner the benefits of genetic medicine, and it encourages "biopiracy," as modern scientists "discover" and patent native plants.

Literature and patent analysis of the cloning and identification of human functional genes in China

The Human Genome Project was launched at the end of the 1980s. Since then, the cloning and identification of functional genes has been a major focus of research across the world. In China too, the potentially profound impact of such studies on the life sciences and on human health was realized, and relevant studies were initiated in the 1990s. To advance China’s involvement in the Human Genome Project, in the mid-1990s, Committee of Experts in Biology from National High Technology Research and Development Program of China (863 Program) proposed the “two 1%” goal. This goal envisaged China contributing 1% of the total sequencing work, and cloning and identifying 1% of the total human functional genes. Over the past 20 years, tremendous achievement has been accomplished by Chinese scientists. It is well known that scientists in China finished the 1% of sequencing work of the Human Genome Project, whereas, there is no comprehensive report about “whether China had finished cloning and identifying 1% of human functional genes”. In the present study, the GenBank database at the National Center of Biotechnology Information, the PubMed search tool, and the patent database of the State Intellectual Property Office, China, were used to retrieve entries based on two screening standards: (i) Were the newly cloned and identified genes first reported by Chinese scientists? (ii) Were the Chinese scientists awarded the gene sequence patent? Entries were retrieved from the databases up to the cut-off date of 30 June 2011 and the obtained data were analyzed further. The results showed that 589 new human functional genes were first reported by Chinese scientists and 159 gene sequences were patented (http://gene.fudan.sh.cn/introduction/database/chinagene/chinagene.html). This study systematically summarizes China’s contributions to human functional genomics research and answers the question “has China finished cloning and identifying 1% of human functional genes?” in the affirmative.     

Human liver proteome project: plan, progress, and perspectives

The Human Liver Proteome Project is the first initiative of the human proteome project for human organs/tissues and aims at writing a modern Prometheus myth. Its global scientific objectives are to reveal the "solar system" of the human liver proteome, expression profiles, modification profiles, a protein linkage (protein-protein interaction) map, and a proteome localization map, and to define an ORFeome, physiome, and pathome. Since it was first proposed in April 2002, the Human Liver Proteome Project has attracted more than 100 laboratories from all over the world. In the ensuing 3 years, we set up a management infrastructure, identified reference laboratories, confirmed standard operating procedures, initiated international research collaborations, and finally achieved the first set of expression profile data.

Integrating physical and genetic maps: from genomes to interaction networks

Physical and genetic mapping data have become as important to network biology as they once were to the Human Genome Project. Integrating physical and genetic networks currently faces several challenges: increasing the coverage of each type of network; establishing methods to assemble individual interaction measurements into contiguous pathway models; and annotating these pathways with detailed functional information. A particular challenge involves reconciling the wide variety of interaction types that are currently available. For this purpose, recent studies have sought to classify genetic and physical interactions along several complementary dimensions, such as ordered versus unordered, alleviating versus aggravating, and first versus second degree.     

Genome screens using linkage disequilibrium tests: optimal marker characteristics and feasibility.

Linkage disequilibrium (LD) testing has become a popular and effective method of fine-scale disease-gene localization. It has been proposed that LD testing could also be used for genome screening, particularly as dense maps of diallelic markers become available and automation allows inexpensive genotyping of diallelic markers. We compare diallelic markers and multiallelic markers in terms of sample sizes required for detection of LD, by use of a single marker locus in a case-control study, for rare monophyletic diseases with Mendelian inheritance. We extrapolate from our results to discuss the feasibility of single-marker LD screening in more-complex situations. We have used a deterministic population genetic model to calculate the expected power to detect LD as a function of marker density, age of mutation, number of marker alleles, mode of inheritance of a rare disease, and sample size. Our calculations show that multiallelic markers always have more power to detect LD than do diallelic markers (under otherwise equivalent conditions) and that the ratio of the number of diallelic to the number of multiallelic markers needed for equivalent power increases with mutation age and complexity of mode of inheritance. Power equivalent to that achieved by a multiallelic screen can theoretically be achieved by use of a more dense diallelic screen, but mapping panels of the necessary resolution are not currently available and may be difficult to achieve. Genome screening that uses single-marker LD testing may therefore be feasible only for young (<20 generations), rare, monophyletic Mendelian diseases, such as may be found in rapidly growing genetic isolates.     

Finding and Mapping New Genes Faster than Ever: Revisited

This article recounts some of the early days of the Human Genome Project, covering the important and sometimes controversial role that complementary DNA-based approaches played in the discovery and mapping of the majority of human genes. It also describes my involvement in this effort and my lab''s development of methods for rapid sequence identification and mapping of human genes.     

The Human Genome Project and eugenic concerns.

The U.S. Human Genome project is the largest scientific project funded by the federal government since the Apollo Moon Project. The overall effect from this project should be of great benefit to humankind because it will provide a better understanding both of single gene defects and multifactorial or familial diseases such as diabetes, arteriosclerosis, and cancer. At first this will lead to more exact ways of screening and diagnosing genetic disease, and later it will lead, in many if not most instances, to specific genetic cures. However, in the past, in both the U.S. and German eugenic movements genetic information has been misused. Hopefully, by remembering and understanding the past injustices and inhumanity of negative eugenics, further misuse of scientific information can be avoided.     

A conversation with John Sulston

Sir John Sulston was a co-winner of the Nobel Prize for Medicine in 2002. He won the prize for his discoveries concerning "genetic regulation of organ development and programmed cell death," along with his colleagues sydney Brenner and H. Robert Horvitz. Dr. Sulston was founding director of the Sanger Centre, Cambridge, England, which he headed from 1992 to 2000. From 1993 to 2000, he led the British arm of the international team selected to work on the Human Genome Project. He is co-author of the book The Common Thread: A Story of Science, Politics, Ethics, and the Human Genome, published by Joseph Henry Press in 2002.This interview was conducted on December 20, 2002, shortly after Dr. Sulston was awarded his Nobel Prize and was originally broadcast on that date on radio station WPKN-FM in Bridgeport, Connecticut. The interview was conducted by Valerie Richardson, the Managing Editor of The Yale Journal of Biology and Medicine.Dr. Sulston has been an outspoken advocate against letting the data from the Human Genome Project become property of commercial interests that would charge the world's scientific community for its use. Since leaving the Sanger Institute, he has worked with OxFam, the Oxford Campaign for Famine Relief.     

Issues concerning ethical conduct and genetic mapping raised at Montreal meeting

Ethical concerns about the Human Genome Diversity Project were discussed in Montreal last year during the 1st International Conference on DNA Sampling and Banking. This article, the second in a 2-part series, looks at the potential for misuse and commercialization of DNA samples and discusses some of the ethical concerns surrounding genetic mapping.
