In September 2005, a paper published in the journal Nature introducing a highly parallel sequencing system capable of producing 100-fold greater throughput than the capillary electrophoresis instrument.

The paper entitled, “Genome Sequencing in microfabricated high-density picolitre reactors,” marks the first in a list of peer-reviewed publications that now boasts over 454, all enabled by the pioneering technology of 454 Sequencing. With 150 publications thus far in 2009, the Genome Sequencer System has the fastest rate of publication and spans the widest range of applications of any next-generation sequencing technology to date, 454 Life Sciences claims.

The 454th paper, published last month in Nature Biotechnology, is just one illustration of the tremendous scientific breakthroughs achieved with the advent of high-throughput sequencing technology.

The study, led by researchers at the Whitehead Institute for Biomedical Research in Cambridge, Mass., used targeted the 454 Sequencing System of mice to analyze the influence of single-nucleotide polymorphisms on miRNA-mediated repression. miRNAs are short, single- stranded RNA molecules that are involved in regulation of gene expression.

“Previously, when we wanted to observe the effects of miRNAs, we had to knock out the miRNA or change its target,” explained David Bartel, study author. “In this study we were able to observe miRNA regulation in the animal, without having to alter either the miRNA or its target.”

A testament to the versatility of the platform, the 454 publications span a wide range of applications, including de novo sequencing, resequencing of whole genomes target DNA regions, metagenomics, and transcriptome analysis. The technology of 454 Sequencing has also been used to enhance our understanding of key agricultural crops, such as maize and oil palm, in order to generate a more sustainable supply of food and energy in the future.

Finally, its use in medical research studies continues to bring us closer to the ultimate vision of personalized healthcare, by identifying the genetic basis of disease and drug response.

The speed at which researchers are publishing highlights the usability of 454 Sequencing data. In one example, researchers at Bielefeld University in Germany used a single sequencing run, generated during the installation of their new Genome Sequencer FLX System, to completely assemble and characterize the genome of Corynebacterium kroppenstedtii. The results from this ‘one run and done’ study were published in the Journal of Biotechnology.

“In only a few short years, sequencing has become an integral tool in nearly all areas of biological research. The sheer breadth of discoveries made possible by the 454 Sequencing System illustrates how the technology is rapidly making an impact on the scientific community,” explained Chris McLeod, President and CEO of 454 Life Sciences, a Roche company. “We are proud to have reached this milestone in the history of genomics and look forward to the next four hundred and fifty-four publications.”
