This article studies the metaphorical expressions used by newspapers to present the near completion of the Human Genome Project (HGP) to the Greek public in the year 2000. The analysis, based on cognitive metaphor theory, deals with the most frequent or captivating metaphors used to refer to the human genome, which give rise to both conventional and novel expressions. The majority of creative metaphorical expressions participate in the discourse of hope and promise propagated by the Greek media in an attempt to present the HGP and its outcome in a favorable light. Instances of the competing discourse of fear and danger are much rarer but can also be found in creative metaphorical expressions. Metaphors pertaining to the Greek culture or to ancient Greek mythology tend to carry a special rhetorical force. However, it will be shown that the Greek press strategically used most of the metaphors that circulated globally at the time, not only culture specific ones.  相似文献

We briefly review the use of metaphors in science and progressively focus on fields from biology and molecular biology to genomics and bioinformatics. We discuss how metaphors are both a tool for scientific exploration and a medium for public communication of complex subjects, by various short examples. Finally, we propose a metaphor for systems biology that provides an illuminating perspective for the ambitious goals of this field and delimits its current agenda.  相似文献

Carrying out research in genetics and genomics and communicating about them would not be possible without metaphors such as “information,” “code,” “letter” or “book.” Genetic and genomic metaphors have remained relatively stable for a long time but are now beginning to shift in the context of synthetic biology and epigenetics. This article charts the emergence of metaphors in the context of epigenetics, first through collecting some examples of metaphors in scientific and popular writing and second through a systematic analysis of metaphors used in two UK broadsheets. Findings show that while source domains for metaphors can be identified, such as our knowledge of electrical switches or of bookmarks, it is difficult to pinpoint target domains for such metaphors. This may be indicative both of struggles over what epigenetics means for scientists (natural and social) and of difficulties associated with talking about this, as yet, young field in the popular press.  相似文献

Abstract

When the Human Genome Project (HGP) was launched, our genome was presented as our ‘blueprint’, a metaphor reflecting a genetic deterministic epistemology. Eventually, however, the HGP undermined rather than strengthened the understanding of genomes as blueprints and of genes as ultimate causal units. A symbolical turning point was the discovery that the human genome only contains~22,500 genes. Initially, this was seen as a narcissistic offence. Gradually, however, it strengthened the shift from traditional genetics and biotechnology (i.e., gene-oriented approaches) to genomics, i.e. genome-oriented or systems approaches, emphasizing complexity. The 20th century can be regarded as the century of biotechnology and of the gene. Its history demonstrated that the will to know (notably: to know ourselves) has never been a disinterested affair: it is driven by a will to improve (notably: to improve ourselves). In this article it is claimed that, as genomics takes us beyond a genetic deterministic understanding of life, this must have consequences for societal research and debate as well. Policies for self-improvement will increasingly rely on the use of complex interpretation. Therefore, the emphasis must shift from issues such as genetic manipulation and human enhancement to issues involved in governance of novel forms of information.  相似文献

Post-genomics allegedly allow us to become the “managers” of our own health. And yet, human individuality seems to dissolve into massive data streams. What is the fate of the human subject in the terabyte age? The Human Genome Project already resulted in personalizing and depersonalizing trends, exemplified by two types of genomes: the anonymized Human Reference Genome versus the personal genomes of genomics celebrities. This ambiguity is radicalized by post-genomics. Life becomes “obliterated”: dissolved into letters and symbols (e.g. the nucleotide alphabet), but this is complemented by re-personalizing trends. As a case study, I will analyze the Snyderome, involving a prominent geneticist who closely monitored “everything” with the help of precision diagnostics, resulting in a comprehensive (“high coverage”) omics portrait, highly personal and highly impersonal at the same time, captured in massive data sets, setting the stage for a digital panopticon: a molecularized “conscience”, the superego of the terabyte age.  相似文献

随着人类基因组计划的完成和功能基因组学的研究的进展,多种结核病候选易感基因被发现,其中人类白细胞抗原(HLA)基因是主要的候选基因之一。HLA基因作为人类最复杂、最具多态性的遗传系统,其功能涉及到机体免疫的各个方面,不同个体对疾病易感性的差异在很大程度上是由遗传因素所决定的,因此HLA基因与某些免疫性疾病的相关性已经成为近年来研究的热点,国内外学者对不同种族的人群对结核分枝杆菌感染的易感性做了大量的研究,探讨HLA基因多态性与结核病遗传易感性的关系。本文对这方面的研究进展做一综述。  相似文献

The Human Genome Project and the ensuing International HapMap Project were largely motivated by human health issues. But the distance from a DNA sequence variation to a novel disease gene is considerable; for complex diseases, closing this gap hinges on the premise that they arise mainly from heritable causes. Using cancer as an example of complex disease, we examine the scientific evidence for the hypothesis that human diseases result from interactions between genetic variants and the environment.  相似文献

Genomics is increasingly considered a global enterprise – the fact that biological information can flow rapidly around the planet is taken to be important to what genomics is and what it can achieve. However, the large-scale international circulation of nucleotide sequence information did not begin with the Human Genome Project. Efforts to formalize and institutionalize the circulation of sequence information emerged concurrently with the development of centralized facilities for collecting that information. That is, the very first databases build for collecting and sharing DNA sequence information were, from their outset, international collaborative enterprises. This paper describes the origins of the International Nucleotide Sequence Database Collaboration between GenBank in the United States, the European Molecular Biology Laboratory Databank, and the DNA Database of Japan. The technical and social groundwork for the international exchange of nucleotide sequences created the conditions of possibility for imagining nucleotide sequences (and subsequently genomes) as a “global” objects. The “transnationalism” of nucleotide sequence was critical to their ontology – what DNA sequences came to be during the Human Genome Project was deeply influenced by international exchange.  相似文献

Issues in genetics and genomics have been centre stage in Bioethics for much of its history, and have given rise to both negative and positive imagined futures. Ten years after the completion of the Human Genome Project, it is a good time to assess developments. The promise of whole genome sequencing of individuals requires reflection on personalization, genetic determinism, and privacy.  相似文献

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.  相似文献

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.  相似文献

As the first assembly of the human genome was announced on June 26, 2000, we have entered post genome era. The genome sequence represents a new starting point for science and medicine with possible impact on research across the life sciences. In this review I tried to offer brief summaries of history and progress of the Human Genome Project and two major challenges ahead, functional genomics and DNA sequence variation research.  相似文献

The Human Genome Project has fueled the massive information-driven growth of genomics and proteomics and promises to deliver new insights into biology and medicine. Since proteins represent the majority of drug targets, these molecules are the focus of activity in pharmaceutical and biotechnology organizations. In this article, we describe the processes by which computational drug design may be used to exploit protein structural information to create virtual small molecules that may become novel medicines. Experimental protein structure determination, site exploration, and virtual screening provide a foundation for small molecule generation in silico, thus creating the bridge between proteomics and drug discovery.  相似文献

The international Human Proteome Project (HPP), a logical continuation of the Human Genome Project, was launched on 23 September 2010 in Sydney, Australia. In accordance with the gene-centric approach, the goals of the HPP are to prepare an inventory of all human proteins and decipher the network of cellular protein interactions. The greater complexity of the proteome in comparison to the genome gives rise to three bottlenecks in the implementation of the HPP. The main bottleneck is the insufficient sensitivity of proteomic technologies, hampering the detection of proteins with low- and ultra-low copy numbers. The second bottleneck is related to poor reproducibility of proteomic methods and the lack of a so-called ‘gold’ standard. The last bottleneck is the dynamic nature of the proteome: its instability over time. The authors here discuss approaches to overcome these bottlenecks in order to improve the success of the HPP.  相似文献
