3 Bullets: When an organism duplicates its genes, it increases its ability to adapt and colonize new environments. ISB researchers used the systems approach to study how one family of microbial genes evolved to bring functions that were adaptive to specific environments. This new understanding of how gene regulatory networks rewire themselves has many potential applications, including how to wire new functions into an organism for biofuel production, bio-remediation or…
3 Bullets: ISB researchers and their collaborators studied a group of supercentenarians (110 years or older) to explore the genetics of ‘extreme longevity.’ The group performed whole-genome sequencing on 17 supercentenarians in order to look for any rare protein-altering variants associated with extreme longevity. While the researchers did not find a single cause for extreme longevity within this sample size, the genomic data is now available for future studies. By…
3 Bullets: Dengue virus is the most prevalent mosquito-borne virus worldwide, infecting an estimated 400 million people per year and causing about 25,000 deaths. It’s necessary to understand the molecular mechanisms of dengue replication in order to develop an effective treatment. Researchers at ISB and Seattle BioMed developed a novel approach for identifying host proteins that associate with dengue replication machinery. By Thurston Herricks Dengue virus (DENV) infects approximately 400…
3 Bullets: Papillary thyroid cancer represents 80 percent of all thyroid cancer cases. Integrative analysis resulted in the detection of significant molecular alterations not previously reported in the disease. ISB researchers identified microRNAs which may lead to more precise therapy. By Lisa Iype Papillary thyroid cancer (PTC) is the most common type of thyroid cancer, accounting for 80 percent of all cases. As part of The Cancer Genome Atlas (TCGA)…
PRESS RELEASE Institute for Systems Biology (ISB) has received a $6.5 million, up to two-year, federally funded contract from the National Cancer Institute (NCI), National Institutes of Health (NIH). ISB is one of three organizations awarded a contract by NCI to develop a cloud-based platform that will serve as a large-scale data repository and provide the computational infrastructure necessary to carry out cancer genomics research at unprecedented scales. ISB’s Shmulevich…
ISB held its all-staff retreat in Leavenworth on Sept. 8 and 9. In order to do the kind of science we do, we need time away to connect with one another, recharge and envision big ideas. While there are plenty of sessions on our science, there are also plenty of opportunities to have a little fun. This year, we held an “open-mic” night. Several ISB staffers performed – including Dr….
3 Bullets: Novel systems approach uses high-resolution structures of protein-DNA complexes to predict where transcription factors (genetic switches) bind and regulate the genome. This approach can help researchers better understand and predict binding sites for non-model organisms or ‘exotic’ species. Having such insight and predictive capabilities is critical for reverse- and forward-engineering organisms that could be pivotal for new green biotechnologies. By Jake Valenzuela and Justin Ashworth Researchers at the…
Pictured above: Dr. Qiang Tian, left, and Dr. Edward Lin, right, discuss single-cell analysis technologies developed at Institute for Systems Biology in Seattle. September 22, 2014 – ISB has received a $2.3 million NIH grant over four years in response to NCI’s “Provocative Questions” Initiative. The project will apply ISB’s most advanced single-cell omics technologies to an innovative clinical trial for colorectal cancer (ADAPT). Principal investigator Qiang Tian, MD, PhD,…
3 Bullets: The Institute for Systems Biology and Seattle BioMed have collaborated to reconstruct the gene regulatory network of the human pathogen Mycobacterium tuberculosis. Finely tuned gene regulation has allowed Mycobacterium tuberculosis to survive unnoticed in an apparently healthy host for decades; understanding those subtleties is critical for advancing treatment. The identification of co-regulated sets of genes and their regulatory influences offers validated predictions that will help guide future research…
3 Bullets: Adams-Oliver syndrome (AOS) is a rare congenital disease characterized by scalp lesions and limb defects. Additional vascular abnormalities and heart defects can lead to early death in some patients. By analyzing twelve families affected with the disease, we identified causal mutations in a new disease gene, NOTCH1, in five families. NOTCH1 is likely to be the major cause of AOS. NOTCH1 codes for a transcription factor that governs…
3 Bullets: Aggressive tumor growth is linked to high activity of a macromolecular assembly called RNA polymerase I. ISB and FHCRC researchers collaborate to map the architecture of the assembly using a powerful crosslinking-mass spectrometry (CXMS) technology. Structural maps provide important insights into therapeutic targets for cancer treatment. By Mark Gillespie Rapidly growing tumor cells require large amounts of protein for their survival. This increased protein synthesis, or translation, can…
3 Bullets: Computer simulation is a promising way to model multicellular biological systems to help understand complexity underlying health and disease. Biocellion is a high-performance computing (HPC) framework that enables the simulation of billions of cells across multiple scales. Biocellion facilitates researchers without HPC expertise to easily build and simulate large models. By Theo Knijnenburg How do molecular changes, such as a mutation in the DNA or infection by a…
The NIH's National Institute of General Medical Sciences has issued a Biotechnology Resource Grant of $10.9 million over five years to the National Center for Dynamic Interactome Research (ncdir.org) project. This project is a collaboration among The Rockefeller University, Institute for Systems Biology, Seattle BioMed, University of California at San Francisco, New York University and New York Structural Biology Center. Michael Rout, of The Rockefeller University, is the Program Director/Principal…
3 Bullets: Gastric cancer has a high mortality rate, but current classification systems haven’t been effective in helping to identify subtypes relevant for treatment of the disease. TCGA researchers have integrated molecular data from 295 stomach tumors and have discovered four subtypes of gastric cancer. Stratification of patients into these four subtypes paves the way for the development of new personalized therapies. By Theo Knijnenburg Gastric cancer is among the…
3 Bullets: Microbes are efficient because their streamlined genomes allow them to evolve and adapt rapidly to complex environmental changes. Decoding the highly-compressed information within a microbial genome requires sophisticated systems biology tools to map the genetic programs, and understand how they are executed. ISB researchers invented novel algorithms to unzip and decode microbial genomes into the EGRIN 2.0, an open-access multiscale model that captures instructions for executing the dynamic…
Institute for Systems Biology has a dizzying breadth of research projects. But when we talk about what we do, it’s how we do it that matters most. The systems approach that we pioneered and exemplify continues to distinguish our ability to tackle the most complex biological and environmental challenges today. Because of how we apply our hallmark collaborative, cross-disciplinary and integrative approach, our collective success is greater than the sum…
3 Bullets: Institute for Systems Biology and Seattle BioMed researchers collaborated and discovered a new protein post-translational modification in the human pathogen Mycobacterium tuberculosis. Post-translational modifications are essential mechanisms used by cells to diversify protein functions and ISB scientists identified the rare phosphorylated tyrosine post translational modification on Mycobacterium tuberculosis proteins using mass spectrometry. Inhibiting phosphotyrosine modified amino acids in Mycobacterium tuberculosis severely limits the growth of this widespread deadly…
