  • science news Unique CDR3 epitope targeting by CAR-T cells is a viable approach for treating T cell April 26

    Efficient and specific removal of malignant cells is the ultimate goal of cancer therapy. The current rapid development of chimeric antigen receptor T cell (CAR-T cell or CART) therapy potentially provides high efficiency and allows long-term surveillance, which have greatly extended the frontier of leukemia treatment.

  • science news Nobel Prize winner, Arieh Warshel took part in the meeting of the IBCh RAS scientific council and joined the international advisory Board of the Institute April 4

    April 3rd 2019, a regular meeting of the IBCh RAS Scientific Council took place, featuring the 2013 Chemistry Nobel Prize awardee, Arieh Warshel.  The scientist delivered a short talk, regarding the prospects of contemporary science and possibilities of using the quantum mechanics calculations to predict the behavior of complex systems, up to the organs and organisms.  Director of our Institute, Alexander Gabibov, announced that professor Warshel had joined the International Advisory Board of the Institute, along with several other distinguished scientists, and presented him a symbolical gift.

  • science news Scientists present a fully genetically encodable bioluminescent system November 26, 2018

    Scientists from Russia, UK, Spain, Brazil, Japan, and Austria discovered the essential set of enzymes that allows glowing fungi to emit light. The bioluminescent system includes a brand- new luciferase and three enzymes that enable biosynthesis of fungal luciferin from a widespread metabolite – caffeic acid – as well as its recycling. The genes encoding this “caffeic acid cycle” make up a unique molecular toolkit that allows to turn any higher organism into a glowing one. The work was published in Proceedings of the National Academy of Sciences of the United States of America.

  • science news Kurt Wüthrich took part in the workshop of the Structural biology department October 10, 2018

    Professor Kurt Wüthrich, Nobel Laureate in Chemistry, 2002, visited Shemyakin–Ovchinnikov Institute of bioorganic chemistry RAS and took part in the workshop of the Structural biology department of the Institute (headed by Prof. Alexander Arseniev).

  • science news Ras-dva: make regeneration great again September 17, 2018

    The researchers from Laboratory of molecular bases of embryogenesis recently hypothesised that the decrease of limb regeneration capacity in amniotes (reptiles, birds and mammals) could be caused by elimination in evolution of genes, encoding for important regulators of specific wound epithelium and blastema organization, which are used by excellent regenerating anamniotes (fish and amphibia). Using two anamniotic model organisms Danio rerio adult fishes and Xenopus laevis tadpoles the authors have shown the essential role of Ras-dva small GTPases in regulation of these processes, meanwhile their genes are eliminated in a stepwise manner during evolution till total absence in placental mammals. The obtained results support the hypothesis. The investigation is published in Scientific reports.

  • science news A bright bantam: BrUSLEE – green fluorescent protein with the unique properties September 7, 2018

    Researchers from the Biophotonics lab of IBCH RAS (Anastasia Mamontova, Konstantin Lukyanov and Alexey Bogdanov) designed a new green fluorescent protein that combines high fluorescence brightness and short fluorescence lifetime. They used a semi-rational protein evolution approach. Their collaborators from Bach Institute of Biochemistry and Semenov Institute of Physical Chemistry helped with the time-resolved fluorescence analysis (FLIM) that allowed characterizing the physical properties of this perspective probe. Research has recently been published in the Scientific Reports.

  • science news Antibiotic from the bear's mouth September 5, 2018

    Scientists from the Laboratory of biocatalysis developed a new microfluidics-based ultrahigh-throughput technology for the “deep functional profiling” of microbial communities and used it to search for bacteria producing new antibiotics in the microbiome of the Siberian bear's oral cavity. This methodology allowed them not only to find the antibiotic amicoumacin, elucidating the mechanisms of its biosynthesis and self-resistance, but also to investigate the spectrum of its activity at the level of various bacterial communities. The results published in PNAS will find numerous applications in the field of antibiotic discovery and will help to solve the problem of antibiotic resistance.

  • science news Spider venom may help to stop neuronal death August 20, 2018

    Venoms of spiders and wasps contain acylpolyamines that act as high-affinity blockers of ionotropic receptors for glutamate, the main excitatory neurotransmitter in the human central nervous system (CNS). The first representative of acylpolyamines, argiopin from the venom of the orb-weaver spider Argiope lobata, was discovered in 1986 by Eugene Grishin’s team at IBCh RAS. Here, an international team of scientists, including a researcher from IBCh RAS, has used cryo-electron microscopy (cryo-EM) to determine the first atomic structure of an argiopin-glutamate receptor complex. This structure will help to design new drugs for treatment of neurodegenerative diseases. The study is published in Neuron.
