Scientists from the Laboratory of bioengineering of neuromodulators and neuroreceptors, the Laboratory of structural biology of ion channels and the Laboratory of neuroreceptors and neuroregulators Shemyakin-Ovchnnikov Institute together with colleagues from the Faculty of biology of Moscow State University and other russian scientific institutes, found that the intranasal administration of the water-soluble analogue of the human neuromodulator Lynx1 can prevent cognitive impairment associated with dysfunction of the α7 type nicotinic acetylcholine receptor.

Researchers from the Group of in silico analysis of membrane proteins structure and the Laboratory of biomolecular modeling of IBCh RAS have predicted the structure of the complex between lantibiotic nisin with the bacterial cell wall precursor — lipid II — on the membrane surface.

Our new article “Albumin-stabilized fluorescent metal nanoclusters: fabrication, physico-chemical properties and cytotoxicity” was recently published in Materials and Design journal. The work was performed by a team of authors from the Scientific Clinical Center for Physico-Chemical Medicine, Moscow Institute of Physics and Technology and IBCh RAS. The researchers of the Electron microscopy group of our institute carried out an important part of the work on direct visualization of the obtained structures, as well as on the measurement of energy dispersive X-ray spectra.

Researchers of the Laboratory of plant functional genomics and proteomics, IBCh RAS, in collaboration with Laboratory of molecular basis of plant stress resistance, IBCh RAS, and James Hutton Institute (United Kingdom) published a review article in the international peer-reviewed scientific journal New Phytologist (IF = 7.29). This review “The role of chloroplast protein remodeling in stress responses and shaping of the plant peptidome” is focused on processes of reorganization of the chloroplast proteome under stress conditions and on the roles of bioactive peptides generated from chloroplast proteins.

The movie Avatar evoked an imaginary world of lush bioluminescent jungles. Now the popular fascination for sustainably glowing foliage is being realized through advances in designer genetics. This week in Nature Biotechnology, scientists have announced the feasibility of creating plants that produce their own visible luminescence.

Small molecules play a critical role in many biological processes and are used as drugs and other research tools.

At the IUPAC initiative the Global Women's Breakfast was held simultaneously on the 12th of February 2020, in different countries all over the world, uniting female scientists from the field of chemistry and related fields in a discussions on current trends in the organization of modern science (https://iupac.org/global-womens-breakfast/). Researchers Zinaida Osipova and Aleksandra Tsarkova of the Laboratory of Chemistry of Metabolic Pathways organized and hosted this event in Moscow in the Institute of Bioorganic Chemistry RAS.

Scientists from the Laboratory of neuroreceptors and neuroregulators helped colleagues from Chengdu University (China) to conduct a series of in vivo experiments on wild-type and knockout by pain sensing receptors TRPV1 and P2X7 animals. It was shown that a stimulation of ST36 acupuncture point leads to an analgesic effect in the model of inflammation from the introduction of a slightly acidic solution into the paw, similar to the effects of selective TRPV1 and ASIC3 ion channel inhibitors. In the model of inflammation from the administration of α, β-meATP (a P2X1,3 purinergic receptor agonist) the ST36 point stimulation also reduced pain sensitivity, but not so effective as the P2X3 antagonist A-317491 or different ASIC3 channel blockers. The results are published in the British Journal of Pharmacology.

Researchers from the Laboratory of Bioinformatics Approaches in Combinatorial Chemistry and Biology IBCH RAS, in collaboration with Irish colleagues, recently published a review in WIRES RNA that compiles the computational approaches, software tools, and data resources that have been developed over the last ten years for ribosome profiling data processing and analysis.

Monitoring of minimum residual disease (MRD) is one of the most important diagnostic tests in the treatment of acute and chronic lymphoblastic leukemia. Currently, several methods for MRD are used, the most sensitive of which is the assessment and monitoring of clonal rearrangements in the immunoglobulin genes characteristic of tumor cells. High sensitivity, up to 1 tumor cell per million, is achieved by using next generation highthroughput sequencing technology (Illumina).
