Genetic Switch May Help Marine Microalgae Respond to Higher CO2 Levels

3 Bullets Rapid climate change, including ocean acidification caused by increasing carbon dioxide (CO2) levels, is predicted to affect the oceans, sea life, and the global carbon cycle. Marine microalgae, including diatoms, are responsible for converting CO2 into oxygen and biologically usable carbon through photosynthesis. How these organisms will respond over the short and long term to rising CO2 is unknown. Growth experiments and transcriptomic analyses performed by UW and…

Baliga Lab: ‘The Universe Under a Microscope’

This is an excerpt from Environmental Microbiology Reports, 2015, authored by Arjun Raman, a postdoc in the Baliga Lab here at Institute for Systems Biology. The beauty of a living thing is not the atoms that go into it, but the way those atoms are put together. Information distilled over four billion years of biological evolution. Incidentally, all the organisms on the Earth are made essentially of that stuff. An…

Tuberculosis Research: A ‘Molecular Road Map’ to Help Understand Gene Regulation

The journal “Trends in Microbiology” recently published a spotlight article on a tuberculosis research collaboration between scientists at Institute for Systems Biology and Seattle BioMed. The paper “The DNA-binding network of Mycobacterium tuberculosis” was published in the journal “Nature Communications” (Jan. 12, 2015): “MTB employs about 200 different molecular switches to sense and respond to the shifting, hostile landscape of the host. To identify and understand the intertwining gene regulatory…

A breakthrough in understanding the genetic ‘architecture’ of bipolar disorder

3 Bullets: Bipolar disorder (BD) is a common, severe and recurrent psychiatric disorder with no known cure and substantial morbidity and mortality. Heritable causes contribute up to 80 percent of lifetime risk for BD. Scientists hope that identifying the specific genes involved in risk for bipolar disorder will lead to new ways to treat the disease. ISB researchers identified contributions of rare variants to BD by sequencing the genomes of…

3 Bullets: ISB researchers used a data-driven mathematical model to identify specific genes associated with hair regeneration Novel methodology paves way for continued research into the molecular basis of this complex cycle as well as other regenerative organs like skin and liver Findings may lead to more precise targets for therapies and genetic markers of hair wellness By Varsha Dhankani Scientists at ISB have identified genes associated with the growth-and-death…

Pushing the Molecular Switches of Tuberculosis Into Overdrive to Map Interactions

3 Bullets: Mycobacterium tuberculosis (MTB) infects more than 1.5 billion people worldwide partly due to its ability to sense and adapt to the broad range of hostile environments that exist within hosts. To study how MTB controls its responses at a molecular level, ISB researchers and their collaborators at Seattle Biomed perturbed almost all MTB transcription factor regulators and identified the affected genes. This comprehensive map of molecular switches in…

The Institute for Systems Biology has a mission to make data available to the world. In a paper recently published in the journal Current Protocols in Bioinformatics, proteomics researchers in the lab of Dr. Robert Moritz provide a step-by-step tutorial demonstrating how to take advantage of web-based applications that let researchers share and use proteomics data.

Let Us Tell You Everything We Know About Proteomics – Everything

3 Bullets: Proteomics experiments generate huge amounts of raw data, most of which cannot be easily shared or described in a publication. ISB researchers curate publicly accessible databases that allow researchers to share their data with the world and to use data others have collected. All data are analyzed in a consistent manner and results are presented via searchable, user-friendly web applications. By Dr. Kristian Swearingen Institute for Systems Biology…

How One Family of Microbial Genes Rewires Itself for New Niches

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…

What’s the Secret to ‘Extreme Longevity’?

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…
