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…

How Physics and Thermodynamics Help Assess DNA Defects in Cancer

3 Bullets: ‘Big data’ cancer research has revealed a new spectrum of genetic mutations across tumors that need understanding. Existing methods for analyzing DNA defects in cancer are blind to how those mutations actually behave. ISB scientists developed a new approach using physics- and structure-based modeling to systematically assess the spectrum of mutations that arise in several gene regulatory proteins in cancer.

New Tool Uses 3-D Protein-DNA Structures to Predict Locations of Genetic ‘On-Off’ Switches

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.
