Creating a new approach to archiving human genetic information

July 08, 2008

A genome sequence is a long sequence written in a four letter code-3 billion letters in the case of a human genome. But what is the meaning-how is the code deciphered? Traditionally this is left to professional annotators who use information from a number of sources (for instance, knowledge about similar genes in other organisms) to work out where a gene starts, stops, and what it does. Even the "gold standard" of professional annotation is an exceptionally slow process. However, new technology may provide a faster solution.

The Public Library of Science is harnessing the power of the internet to improve access to information, and to facilitate discussion and the understanding of science. In this week's issue of PLoS Biology, we are very pleased to present information on an independent project working towards the same goals. Andrew Su, John Huss III and colleagues describe their efforts to establish a 'Gene Wiki'-an online repository of information on human genes, stored within Wikipedia. They envision a network of articles, created by a computer program and enhanced by user comments, which will describe the relationship and functions of all human genes.




There is a lot of potential information about any given gene-its name, sequence, position on a chromosome, the protein(s) it encodes, other gene(s) it interacts with, etc. and presenting this information is referred to as 'gene annotation.' As information may come from many different researchers working independently, it is important that resources exist to collect the information together. Existing annotation libraries include Gene Portals and Model Organism Databases-however, the information stored in these is considered to be definitive, which requires constant updates by specific experts and formal presentation of information. The work reported in this week's PLoS Biology is intended to allow a much more flexible, organic accumulation of science, with all readers also able to edit and add to the Gene Wiki pages.

In order to stimulate the development of this Wikipedia based resource, Andrew Su and colleagues developed a system that automatically posts information from existing databases as 'stub' articles on Wikipedia. A computer program downloads information from one system, formats it according to Wiki formatting and the 'stub' template that the authors have designed, and-if a page does not already exist for that gene-posts the information on Wikipedia. The authors are confident that their stubs will seed the posting of more detailed information from scientists who encounter them on Wikipedia-and they report that, so far, they appear to be succeeding: the absolute number of edits on mammalian gene pages has doubled.

Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis.

Scientists find new clues to explain Amazonian biodiversity
Ice age climate change and ancient flooding-but not barriers created by rivers-may have promoted the evolution of new insect species in the Amazon region of South America, a new study suggests.

Viral recombination another way HIV fools the immune system
When individuals infected with HIV become infected with a second strain of the virus, the two viral strains can exchange genetic information, creating a third, recombinant strain of the virus. It is known that the presence of multiple viral strains, called superinfection, frequently leads to a loss of immune control of viral levels.

The Emergence of Genetic Rationality: Space, Time, & Information in American Biological Science, 1870-1920 (In Vivo: the Cultural Mediations of Biomedical Science)
by Phillip Thurtle

The emergence of genetic science has profoundly shaped how we think about biology. Indeed, it is difficult now to consider nearly any facet of human experience without first considering the gene. But this mode of understanding life is not, of course, transhistorical. Phillip Thurtle takes us back to the moment just before the emergence of genetic rationality at the turn of the twentieth century...

Brain Arousal and Information Theory: Neural and Genetic Mechanisms
by Donald Pfaff

Arousal is fundamental to all cognition. It is intuitively obvious, absolutely necessary, but what exactly is it? In Brain Arousal and Information Theory, Donald Pfaff presents a daring perspective on this long-standing puzzle. Pfaff argues that, beneath our mental functions and emotional dispositions, a primitive neuronal system governs arousal. Employing the simple but powerful framework of...
