Applied Biosystems Genomic Analysis Platform Fuels New Era of Life-Sciences Research
When Applied Biosystems (NYSE:ABI), an Applera Corporation business,
introduced its ultra-high-throughput genomic analysis system less than a
year ago, the company entered a new era of life-science research,
enabling scientists to adopt new approaches for studying the genetic
basis of health and disease. Researchers at the Broad Institute of MIT
and Harvard, as well as Columbia University Medical Center (CUMC), have
adopted innovative approaches for their research related to large-scale
discovery of genetic variation and cancer research, respectively. This
week, scientists from these institutions will present preliminary
findings from their research using the SOLiD™
System at the Cold Spring Harbor Laboratory’s
Biology of Genomes meeting in New York.
As part of its ongoing commitment to commercializing best-in-class
genomic analysis platforms, Applied Biosystems today announced
significant new enhancements to the SOLiD System platform, the company’s
new technology for DNA sequencing and genomic analysis research. These
include upgrades to software and chemistry that double throughput,
simplify workflows and decrease system run times. These enhancements are
expected to support future innovative approaches to some of the most
important areas of research for the scientific community.
"The SOLiD System has already had a tremendous
impact in driving significant life-science research, including important
projects related to medically relevant genetic variation and cancer
research,” said Shaf Yousaf, president for
Applied Biosystems’ molecular and cell biology
genomic analysis division. "These new
performance enhancements enable the SOLiD System to continue to
establish new standards for ultra-high-throughput genomic analysis,
helping Applied Biosystems to maintain its established leadership in DNA
sequencing and other high-throughput genomic analysis applications.” Large-Scale Discovery of Genetic Variation at the Broad Institute
Researchers at the Broad Institute are using the SOLiD System for
large-scale discovery of genetic variation in human genome samples. This
research is expected to be included as part of the Broad Institute’s
contribution to the 1000 Genomes Project, a worldwide research effort
sponsored by the National Human Genome Research Institute (NHGRI), the
Wellcome Trust and the Beijing Genomics Institute. This project will
involve the sequencing of 1,000 genomes from people from around the
world to create the most detailed and medically useful picture to date
of human genetic variation. The data generated as part of the 1000
Genomes Project are expected to reveal clues about how variant DNA
sequences contribute to conditions such as cancer, diabetes and heart
disease.
In analysis of DNA single base changes – also
known as SNPs (single nucleotide polymorphisms) –
scientists at the Broad Institute used two SOLiD Systems to generate
more than 50 billion bases of DNA sequence over the past six weeks. At
the Cold Spring Harbor Laboratory meeting, Dr. Chad Nusbaum, co-director
of the Broad Institute’s genome biology
program, will present highly accurate polymorphism discovery data from a
human genome sample that belongs to a trio, which is a family of a
father, mother, and offspring. Among other findings, Dr. Nusbaum’s
team will report that SNPs discovered as a result of using the SOLiD
System were matched with high accuracy to a database of known SNPs.
Genomic analysis platforms capable of ultra-high throughput are quickly
becoming established as the standard for the study of complex genomes
because as the technologies mature, the cost of analysis continues to
decrease. The Broad Institute completed sequencing experiments with
yields of up to 13.4 billion bases per run; more than two times the
number of bases that comprise an entire diploid human genome.
Methylation Profiling Studies at Columbia University Medical Center
Reveal Clues about Breast Cancer
The SOLiD System is helping researchers at Columbia University Medical
Center (CUMC) to develop new approaches to methylation profiling studies
of cancer. In these kinds of studies, researchers evaluate patterns of
methylation, which is a chemical modification to DNA, at CpG sites in
the genome. Dense regions of these sites are often located near gene
promoters and within repetitive regions of the genome, where cytosine
(C) and guanine (G) nucleotides are present in tandem at greater
frequency than in other parts of the genome. Researchers study patterns
of methylation in these CpG-rich regions as to better understand how
methylation contributes to cancer.
These scientists, including Dr. John Edwards, associate research
scientist at CUMC’s genome center, and Dr.
Timothy Bestor, a professor in CUMC’s
department of genetics and development, have been using the SOLiD System
to help carry out a novel approach for studying whole-genome methylation
profiles of a panel of breast cancer tumors and normal controls. This
approach incorporates the mate-pair analysis capabilities of the SOLiD
System to map the methylation state of all regions of the genome,
including promoters, genic regions, and repetitive elements. Mate-pair
analysis – the ability of a genetic analysis
system to analyze pairs of sequences separated by a known distance
between them – allows researchers to
precisely determine where those sequences are located in the genome.
At the Cold Spring Harbor Laboratory meeting this week, Dr. Edwards will
present data of whole-genome methylation profiles of a panel of tumors
and matched normal controls that show, for the first time, in a whole
genome context, the differences in methylation patterns between normal
and tumor breast tissue. Based on this data, Dr. Edwards will describe a
new role for methylation in cancer, where methylation changes in
particular regions of cancer genomes may reflect a cellular defense
system that kills cancerous cells.
"Using the SOLiD System, we have interrogated
the methylation status of more than 500 million CpG sites, which far
exceeds the sum total of methylation data previously available,”
said Dr. Bestor. "The DNA data quality of
runs from the platform that included the new performance enhancements
has been excellent.” SOLiD System Enhancements Set New Levels of Performance and
Ease-of-Use for Genomic Analysis
Applied Biosystems this week is making available new upgrades to
chemistry and software that will double throughput, simplify workflows
and decrease system run times. These enhancements will be a part of all
future shipments of the SOLiD System. These enhancements will also be
made available to existing customers through local service and support
teams located around the world.
With these new enhancements, the SOLiD System can consistently generate
more than 6 billion bases of sequence data per run, which doubles
throughput levels compared to when the system became commercially
available just six months ago. This level of throughput maintains the
SOLiD System as the highest throughput genomic analysis system available
today. The SOLiD System is expected to scale further, as it has already
demonstrated more than 10 billion bases per run at some customer
locations, and up to 17 billion bases at Applied Biosystems’
research and development facilities.
In addition to the number of bases sequenced per run, throughput can
also be measured by the number of sequence tags that a genetic analysis
system can generate for quantitative applications, such as gene
expression profiling, identification of transcription factor binding
sites, and serial analysis of gene expression (SAGE). Sequence tags,
derived from short pieces of mRNA transcripts, are used for
sequencing-based quantitative gene expression techniques. These
techniques, such as SAGE, are used to rapidly identify differences in
genome-wide patterns of gene expression, which could be associated with
disease, regulatory cell networks or cell differentiation. With the
upgrades to software and chemistry announced today, the SOLiD System now
generates up to 240 million sequence tags per run. This increase in
throughput of sequence tags is expected to further reduce the cost of
conducting sequencing-based gene expression applications.
Upgrades to chemistry and software have also resulted in improvements to
sample preparation methods. These improvements are expected to result in
simplified workflows, with less DNA sample now being required for use in
DNA sequencing and RNA analysis applications. The number of manual
pipetting steps researchers need to perform when preparing samples used
in emulsion PCR have also been reduced. A smaller emulsion device, an
optimized emulsion PCR protocol, and software upgrades have
significantly shortened run times for both fragment and mate-pair
library runs. Another result is higher quality data for most sequencing
reactions, including more even representation of bases across the entire
sequence composition range – GC content –
of the genome.
Many of the new performance enhancements are possible because of the
inherent scalability and flexibility of the SOLiD System platform.
Unparalleled throughput and scalability distinguish the SOLiD System
infrastructure from other genomic analysis sequencing platforms. The
system can be scaled to support a higher density of sequence reads per
slide through bead enrichment. Beads are an integral part of the SOLiD
System’s open-slide format architecture. The
combination of the open-slide format, bead enrichment, and software
algorithms provide the infrastructure for allowing it to scale to even
higher throughput, without significant changes to the platform’s
current hardware or software. The SOLiD System also has the flexibility
to accommodate future approaches to life science research. For example,
the unique flexibility of the system’s
2-slide format enables researchers to simultaneously perform two
independent applications, such as genotyping and gene expression.
