LANL leads the world in computational finishing of microbial genomes
Los Alamos National Laboratory graduate student, Patricia Langan, changes the properties of a green fluorescent protein in order to create new fluorescent protein variants.
Researchers at Los Alamos National Laboratory are using their renowned expertise in genomics, computation, and experimental biology as the foundation of a dynamic systems biology capability.
Systems biology examines biological components in an integrated fashion—genes, proteins, cells, communication networks, community consitituents—and how their interactions give rise to the function and behavior of larger systems. Furthermore, incorporation of synthetic biology enables these systems to be improved.
The LANL portfolio includes sequencing, metabolomics, proteomics, transcriptomics, network analysis, computational modeling, and other methods that can be coupled tightly with experimental systems to both understand and predict their behavior.
This approach promises to enhance all aspects of biological research such as:
- Increasing the specificity of pathogen detection
- Designing more effective drugs through understanding the host-pathogen relationship
- Advancing plant and algal growth for bioenergy production
- Analyzing changes in the climate based on diverse microbial ecology
LANL has a rich history in genomic science – from the inception of the Human Genome Project and GenBank, to leading the world in computational finishing of microbial genomes and partnering with the DOE Joint Genome Institute.
Today, with rapidly advancing sequencing technology and the need for novel bioinformatics processes, our role continues to evolve and Los Alamos scientists are applying their expertise in sequencing and bioinformatics analysis toward challenges in bioenergy, pathogen detection, and microbial ecology.
In addition, scientists are developing new strategies to achieve these goals—such as experimental methods to isolate sufficient DNA from single cells and novel algorithms to help analyze metagenomes.
Los Alamos scientists also utilize other ‘omics such as transcriptomics, proteomics, structural biology, and metabolomics. Coupled with cross-discipline expertise in sequencing, protein structure and function characterization, bioinformatics, and modeling with our national centers for stable isotopes, and flow ctyometry, Los Alamos scientists are gaining a better understanding of relevant biological systems:
- Understanding the dynamics and treatments of viral diseases, such as HIV, influenza, and hepatitis.
- Explore the complex soil community of bacteria and fungi using metagenomic and transcriptomic approaches
- Designing computer models of the human immune system.
- Analyzing receptor-ligand interactions and cell signaling
- Examining host and pathogen response to infection
- Understanding the evolution of organisms in various systems
- Ascertaining protein function and dynamics, as well as protein folding.
- Using metabolomics to understand and impact plant growth
- Created NanoCluster Beacons that use a collection of a few atoms of silver as fluorescent reporters and are designed to bind with specific nucleic acid targets, such as pathogenic DNA. Reversible, inexpensive, and easy to use, NanoCluster Beacons are superior molecular probes that can be use to detect specific targets, such as influenza DNA or human oncogene (cancer) sequences, as well as play a crucial role in the study of sophisticated gene regulatory networks that could lead to a better understanding of cellular function. NanoCluster Beacons received an R&D 100 Award in 2011.
- Invented a rapid assay of protein folding by using the folding of a green fluorescent protein to monitor the folding of a test protein. It does this by linking the two proteins in a hybrid molecular with the characteristics of both. Applications include identifying the soluble proteins needs for medical research, drug discovery, chemical industrial process, and basic research into the structure and functions of proteins.
- Created “gel microdroplets,” to help scientists generate complete genomes from a single cell, thus opening the door to understanding the complex interrelationships of bacteria, viruses and eukaryotes that form “microbiome” communities in soil, in humans, and elsewhere in the natural world.
- Developed Sequedex, a software package that performs the first step in analyzing the output of DNA sequencing instruments—classifying the organism the DNA likely came from and the metabolic function it likely carries out—faster, more sensitively, and more accurately than previously possible. Sequedex received an R&D 100 Award in 2012.
- Developed “BugBrowser,” a Java-based software project that provides highly flexible and dynamic visualization of the many features of viral, bacterial, and plasmid genomes. The tool can be used to visually compare multiple genomes, with an emphasis on gene similarity.
- Developing mathematical models of complex biological systems that play a role in cellular signaling. Developments include software such as BioNetGen (models biochemical networks inside cells) and EcoTFS (database that catalogs data regarding autoregulation of transcription factors in Escherichia coli).
- Development of ‘omics approaches to identify key soil bacterial and fungal populations in soil carbon cycling in forest and arid land ecosystems, (b) determination of genes and enzymes through which those populations process soil carbon, (c) the influence of anthropogenic N deposition on these processes, and (d) design of scalable molecular assays toward improved input for soil process models.
- Coupling algae sequence information with transcriptomics, proteomics, and metabolomics data to understand the biochemistry of high lipid production and to best inform decisions on feedstock choices for biofuel development
- Proven expertise, and world leader in delivering high quality genome products and leading the field in generating libraries from low input DNA (including single cells)
- Developed workflows now used in production at major sequencing centers (e.g. JGI) to perform metagenome assembly for hundreds of projects
- Collaborating with the Centre for Chemical Biology at the Unversiti Sains Malaysia on a human genome project to study achondroplasia disorder, the most common form of dwarfism. This work will provide clues to diagnose, treat, and prevent this and other genetic disorders.
- Working with the Kyrgyzstan Institute of Biotechnology to develop a genome database related to animal husbandry. The goals of this project are to define the genetic nature of commercial farm animals like sheep, identify opportunities to protect and preserve local indigenous breeds, and develop a genetic database for future selection of rare breeds for further research and commercial applications.
- Los Alamos was a key participant in the Human Genome Project. The goal of this project was to understand the genetic makeup of the human species and answer questions about human evolution, human interrelationships with other living things, and how humans differ from one another.
