  • Chloroplast-Mediated Regulation of CO2-Concentrating Mechanism by Ca2+-Binding Protein CAS in the Green Alga Chlamydomonas Reinhardtii

    Application example of HvYolution Super-Resolution - Aquatic photosynthetic organisms, including the green alga Chlamydomonas reinhardtii, induce a CO2-concentrating mechanism (CCM) to maintain photosynthetic activity in CO2-limiting conditions by sensing environmental CO2 and light availability. In this study, the introduction of an intact CAS gene into H82 cells restored photosynthetic affinity for inorganic carbon, and RNA-seq analyses revealed that CAS could function in maintaining the expression levels of nuclear-encoded CO2-limiting–inducible genes, including the HCO3– transporters high-light activated 3 (HLA3) and low-CO2–inducible gene A (LCIA).

  • Video Talk by Roger Tsien: Fluorescent Protein Indicators

    In this talk, Roger Tsien discusses how fluorescent proteins have been turned into indicators for a wide variety of biological molecules, including pH, ions, redox potential, and signaling molecules like phosphoinositides. The talk also covers reporters used to measure the activity of enzymes like kinases, phosphatases, and proteases. It covers both single proteins whose intensity or wavelength change, as well as reporters using resonance energy transfer (FRET).

  • Targeting of Peroxisomal Matrix Proteins in the Diatom Phaeodactylum Tricornutum

    P. tricornutum cells expressing different types of GFP fusion proteins were harvested via centrifugation at 1,500xg and cryoimmobilized by high-pressure freezing on gold carriers.

  • Stem Cells in the Aging Process – the Signal Protein p53 as "Guardian of the Genome"

    The physiological process of aging is an elementary part of life. The processes responsible for the aging process and the effect they have is one of the key focuses of biomedical research. Dr. Yvonne Begus-Nahrmann researches molecular mechanisms in stem cells and their role in aging and tumor development at the Göttingen University Medical Center. Signal proteins such as p53 and p21 appear to play an important role in this context. To investigate these proteins in specific cell types, the cells are isolated from organ tissue with the aid of laser microdissection.
