How the methods of Bioinformatics bring genetic research to people?

Computational biologists begin to develop easy-to-use tools to analyse and interpret data on the genetic sequence.

Gene sequencing technologies may allow doctors to treat patients with symptoms who have no apparent cause to make a Diagnosis. However, because of the large quantities of data, it can be difficult to get a fast response.

Until a few years ago, US Naval Medical Research Unit (NAMRU-6) physicians in Lima needed the sequence data to be sent to the US for review, which could take weeks – too long to reach pressing treatment decisions.

If all you could do was get the data that you then have to ship to the US, it’s almost useless,” says Mariana Leguia, who heads the centre’s genomics and pathogen-discovery unit.

But Leguia doesn’t have to wait anymore for analyses; in days and hours, she can get results and can do them in her laboratory. Her device uses the EDGE(Empowering the Development of Genomics Expertise), a bioinformatics method to conceal typical microbial-genomic activities, such as sequence assembly and speciation recognition, behind a smooth, polished research screen. “We will get operational details on the web so that we can determine very easily how to proceed,” says Leguia.

EDGE is not the first tool with a dot-and-click gui to simplify computing. Indeed, much of the versatility and reach of more developed alternatives such as the BaseSpace framework for Galaxy and Illumina is lacking.

But it is possible for consumers to stop bioinformatics. It is convenient. Clinton Paden, who uses EDGE in his work on virus pathogenesis at the US Centres pour le Disease Control et Prevention in Atlanta, Georgia:

“There have been people who have never bothered to learn command line-level techniques.” It is, therefore, a case study in the democratisation of genome information technology — one which can help pure biologists accelerate the takeover of the field.

Working grounds of Bioinformatics

Patrick Chain, who led the software development, says that EDGE was created in New Mexico at the Los Alamos National Laboratory (LANL) to try to balance the increasingly increasing availability of low-cost DNA sequencing systems with a relative lack of information needed to understand the data.

Joe Anderson, a computer biologist who has developed military application software for the Biologic Defense Research Directorate (BDRD) at Naval Medical Research Center in Frederick, Maryland, says it’s intended for installations that lack expertise in bio-informatic science.

It is also open-source and autonomous and offers end-to-end microbial Genomics analyses with just one click from a raw sequence to species identity and phylogeny. The system itself is relatively inexpensive since it is possible to buy less than US$ 10,000 in the recommended hardware configuration (256 gigabytes of memory and 64 processors).

This allows most laboratories which can run projects in sequence to provide the hardware. “It is not cashing money, but it’s pretty cheap,” he says. The device can also be operated by a generator without an Internet connexion.

A framework can be deployed on a cloud network by users with secure network connexions. CLIMB, the Cloud Platform for Microbial Bioinformatics was created by Nicholas Loman, a bioinformatics scientist at Birmingham University, UK. CLIMB is a free service devoted to researchers specialising in microbial genomics in the United Kingdom.

The UK medical research council funded CLIMB for £8,4 million ( US$ 10,5 million), which includes many IT instruments, including sequence databases and the Genomics Virtual Laboratory study workshop. “There is certainly an alternative I am thinking of EDGE,” Loman says.

Theron Hamilton, head of genomics and bioinformatics for the BDRD, says EDGE has been officially developed in 18 US Defense and partner-nation laboratories on all continents except Antarctica.

One of them is in Phnom Penh, NAMRU-2, which monitors vector-borne illnesses with the system. “Traditionally, it’s not the kind of place to do bioinformatics,” Anderson said. EDGE changes that, though. “With [researcher] devices, one of the things I know is that they’re going to amaze you if you get out of the way,” said Anderson.

Includes 54 tools from third parties the newest edition of EDGE – edition 1.5, launched last October. The series operates six interlocking analytical modules, including algorithms, databases, visualisation software and the genomes of references: sequence cleanup, assembly and annotation, reference genomes comparison, taxonomic recognition, evolutionary analysis, and a PCR primary architecture. For the upcoming EDGE 2.0 more modules are to be added including RNA analytics and pathogen detection.

Kathleen Fisch, Interim Director of the Center for Computative Biology and Bioinformatics, University of California, adds that they need to understand how the algorithms function and how different parameters influence their performance, as with any method. ““Just because you can run the tools doesn’t mean that you should run the tools.”

However, with bioinformatics instruments becoming ever simpler, IT may lose some of their aura of mystery. And that could lead to broader acceptance for biologists – and democracy.
