- science news Genetically encoded fluorescent pH probe for precise monitoring of cellular biochemistry
One of the directions of the Molecular Technologies Laboratory is the development of new tools for bioimaging and optogenetics. Yulia Ermakova, Vsevolod Belousov and other lab members, in an article in Chemical Communications, describe a new member of SypHer family of genetically encoded pH indicators, SypHer3s.
- science news Spider venom will cure from paralysis
Scientists from IBCh RAS together with foreign colleagues discovered that a toxin from the venom of the spider Heriaeus melloteei may serve as a hit in drug discovery for hypokalemic periodic paralysis type 2. The disease is caused by mutations in the gene encoding voltage-gated sodium channels NaV1.4, characteristic of skeletal muscles. As a result of the mutations, these channels conduct aberrant currents, the muscles are unable to respond to the signals of the nervous system, and weakness develops followed by paralysis. Until now, there is no reliable medication for all cases of this disease. The results of the work are published in the Proceedings of the National Academy of Sciences of the USA (PNAS).

- science news Academician A.G. Gabibov and Professor J. Schlessinger handed over the Lomonosov Great Gold Medal to Professor Sidney Altman
October 13, 2017
Acting Director of the Institute of Bioorganic Chemistry RAS, President of the Russian Biochemistry and Molecular Biology Society, academician Alexander Gabibov and the head of the Pharmacology Department at Yale University, a member of the US National Academy of Sciences and a foreign member of the RAS, member of the International Advisory Board of Institute of Bioorganic Chemistry of the RAS Joseph Schlessinger on behalf of the President of the Russian Academy of Sciences awarded the Lomonosov Great Gold Medal to the laureate of 2016, Professor at Yale University, a member of the International Advisory Board of Institute of Bioorganic Chemistry RAS, Nobel Prize laureate Sidney Altman. Professor Altman has received the award "for outstanding contribution to the field of biochemistry of nucleic acids, the discovery of the catalytic activity of the nucleic acids and the creation of new biologically active substances."
- science news The international forum was held at the IBCh RAS
October 12, 2017
The Joint Life Sciences Forum, including the International Scientific Conference in bioorganic chemistry "XII conference dedicated to the Memory of Academician Yuri A. Ovchinnikov" and the VIII Russian Symposium "Proteins and Peptides" with a Young Scientists Competition, was held at the Institute of Bioorganic Chemistry RAS at 18-22 September, 2017. The leading foreign experts who visited the forum named it one of the main scientific events in the field of Life Sciences in the world in this year.
- science news Laboratory of the IBCh first in Russia received a foreign order for preclinical testing of substances by world standards
October 5, 2017
Laboratory of Biological Tests of the Branch of the Institute of Bioorganic Chemistry (BICh) received an order from a European company for preclinical animal studies, which will be conducted in accordance with world standards. Thus, for the first time, Russia will export high-tech services such as pre-clinical research for foreign countries.
- science news Scientists made proteins shine longer
September 1, 2017
Russian scientists together with foreign colleagues extended the shine time of fluorescent label in live cells. Light is emitted longer due to the continuous exchange of fluorogenic dyes interacting with special protein labels. The method which was described in the Chemical Science journal will simplify the live cells staining and provide new opportunities for research. This work was supported by the Russian Science Foundation.
- science news Researchers from IBCh found out how the protein isoforms diverse
August 16, 2017
Researchers of the IBCh RAS and the Federal Research and Clinical center of Physical-Chemical Medicine of FMBA of Russia found that alternative splicing of messenger RNAs makes a non-significant contribution to the plant cell proteome diversity. The results have been published in the Scientific Reports journal.
- science news Chemists discovered a new mechanism of action of a Vipera nikolskii venom neurotoxin
June 8, 2017
Scientists from the Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry RAS (IBCh RAS) with the participation of colleagues from the Institute of Human Morphology of RAMS and the Pirogov RSMU found that the enzyme phospholipase A2 from the Vipera nikolskii venom is able to adhere to lipid membranes (prototypes of cell membranes) and cause their aggregation, even if the activity of enzyme is specifically blocked. It turned out that this is due to the presence of two binding sites in the enzyme structure. Published in the journal Toxicon the results of the work help to understand how the multicomponent snakes’ venoms work.
- science news The researchers of the IBCh RAS took part at the international conference nAChR 2017
May 31, 2017
From 7 to 11 May the fourth international conference on nicotinic acetylcholine receptors (nAChR 2017) was held on the island of Crete (Greece) in which scientists from the Institute of Bioorganic Chemistry RAS took part. Together with other leading experts in the field of neurobiology associated with cholinergic transmission, they discussed the genetic, molecular, structural and cellular aspects of research and told what key trends in the development of this scientific area are actively supported now.
- science news Russian scientists study to control a neural network through infrared radiation
May 26, 2017
Researcher from the Institute of Bioorganic Chemistry of the Russian Academy of Sciences together with their colleagues have developed a method for stimulating neurons with infrared radiation. They implemented in mice neurons snake proteins that react to temperature – thermoreceptors. Published in Nature Communications journal results will help non-invasive stimulate neural networks in the deep layers of tissues in the body, as well as control the activity of other types of cells in living systems. In the future, it can help in the therapy of various nervous system diseases.
