HISTORY AND ORIGIN OF BIOINFORMATICS

The following year, the Human Genome Project was started. By 1991, a total of 1879 human genes had been mapped. In 1993, Genethon, a human genome research center in France Produced a physical map of the human genome. Three years later, Genethon published the final version of the Human Genetic Map. This concluded the end of the first phase of the Human Genome Project.

Bioinformatics was fuelled by the need to create huge databases, such as GenBank and EMBL and DNA Database of Japan to store and compare the DNA sequence data erupting from the human genome and other genome sequencing projects.
Today, bioinformatics embraces protein structure analysis, gene and protein functional information, data from patients, pre-clinical and clinical trials, and the metabolic pathways of numerous species.

Origin of bioinformatic/biological databses:
The first bioinformatic/biological databases were constructed a few years after the first protein sequences began to become available. The first protein sequence reported was that of bovine insulin in 1956 , consisting of 51 residues. Nearly a decade later, the first nucleic acid sequence was reported, that of yeast alanine tRNA with 77 bases. Just a year later, Dayhoff gathered all the availablesequence data to create the first bioinformatic database .
The Protein DataBank followed in 1972 with a collectionof ten X-ray crystallographic protein structures, and theSWISSPROT protein sequence database began in 1987. A huge variety of divergent data resources of different typesand sizes are now available either in the public domain or more recently from commercial third parties. All of the original databases were organised in a very simpleway with data entries being stored in flat files, either one perentry, or as a single large text file. Re-write - Later on lookup indexes were added to allow convenient keyword searching of header information.

Origin of tools:
After the formation of the databases, tools became available to search sequence databases - at first in a very simple way, looking for keyword matches and short sequence words, and then more sophisticated pattern matching and alignment based methods. The rapid but less rigorous BLAST algorithm has been the mainstay of sequence database searching since its introduction a decade ago, complemented by the more rigorous and slower FASTA and Smith Waterman algorithms. Suites of analysis algorithms, written by leading academic researchers at Stanford, CA, Cambridge, UK and Madison, WI for their in-house projects, began to become more widely available for basic sequence analysis. These algorithms were typically single function black boxes that took input and produced output in the form of formatted files. UNIX style commands were used to operate the algorithms, with some suites having hundreds of possible commands, each taking different command options and input formats. Since these early efforts, significant advances have been made in automating the collection of sequence information. Rapid innovation in biochemistry and instrumentation has brought us to the point where the entire genomic sequence of at least 20 organisms, mainly microbial pathogens, are known and projects to elucidate at least 100 more prokaryotic and eukaryotic genomes are currently under way. Groups are now even competing to finish the sequence of the entire human genome. With new technologies we can directly examine the changes in expression levels of both mRNA and proteins in living cells, both in a disease state or following an external challenge. We can go on to identify patterns of response in cells that lead us to an understanding of the mechanism of action of an agent on a tissue. The volume of data arising from projects of this nature is unprecedented in the pharma industry, and will have a profound effect on the ways in which data are used and experiments performed in drug discovery and development projects. This is true not least because, with much of the available interesting data being in the hands of commercial genomics companies, pharmcos are unable to get exclusive access to many gene sequences or their expression profiles. The competition between co-licensees of a genomic database is effectively a race to establish a mechanistic role or other utility for a gene in a disease state in order to secure a patent position on that gene. Much of this work is carried out by informatics tools. Despite the huge progress in sequencing and expression analysis technologies, and the corresponding magnitude of more data that is held in the public, private and commercial databases, the tools used for storage, retrieval, analysis and dissemination of data in bioinformatics are still very similar to the original systems gathered together by researchers 15-20 years ago. Many are simple extensions of the original academic systems, which have served the needs of both academic and commercial users for many years. These systems are now beginning to fall behind as they struggle to keep up with the pace of change in the pharma industry. Databases are still gathered, organised, disseminated and searched using flat files. Relational databases are still few and far between, and object-relational or fully object oriented systems are rarer still in mainstream applications. Interfaces still rely on command lines, fat client interfaces, which must be installed on every desktop, or HTML/CGI forms. Whilst they were in the hands of bioinformatics specialists, pharmcos have been relatively undemanding of their tools. Now the problems have expanded to cover the mainstream discovery process, much more flexible and scalable solutions are needed to serve pharma R&D informatics requirements.

                     There are different views of origin of Bioinformatics- From T K Attwood and D J Parry-Smith's "Introduction to Bioinformatics", Prentice-Hall 1999 [Longman Higher Education; ISBN 0582327881]: "The term bioinformatics is used to encompass almost all computer applications in biological sciences, but was originally coined in the mid-1980s for the analysis of biological sequence data."

                     From Mark S. Boguski's article in the "Trends Guide to Bioinformatics" Elsevier, Trends Supplement 1998 p1: "The term "bioinformatics" is a relatively recent invention, not appearing in the literature until 1991 and then only in the context of the emergence of electronic publishing. The National Center for Biotechnology Information (NCBI) , is celebrating its 10th anniversary this year, having been written into existence by US Congressman Claude Pepper and President Ronald Reagan in 1988. So bioinformatics has, in fact, been in existence for more than 30 years and is now middle-aged."
