In a study published in Genome Biology and Evolution, researchers at Institute for Systems Biology (ISB) designed an experiment to evolve novel adaptive prediction capability in yeast by repetitively exposing it to caffeine, followed by a toxin. Remarkably, the yeast cells learned the structure of this novel environmental pattern within as few as 50 generations to use caffeine as a cue for anticipating and mitigating lethal effects of the toxin.
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: ISB researchers are studying peroxisomes, which are cellular organelles that are linked to a rare syndrome that causes progressive organ complications and infant mortality. Peroxisomes have a role in metabolizing and breaking down cellular waste. Because peroxisomes easily change shape and function according to a cell’s needs, a systems approach is necessary to help decipher that complexity. By Dr. Thurston Herricks Dane Tolmie was a 19-month old boy…
