From cytoskeleton to pluripotency: a new mechanism for regulating stem status of the embryonic cells
Researchers from the Laboratory of Molecular Bases of Embryogenesis (Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry RAS), in technical cooperation with colleagues from the Department of Metabolism and Redox Biology (Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry RAS), the Laboratory of Genomics and Epigenomics of Vertebrates in the Federal Center "Fundamentals of Biotechnology" RAS, as well as with colleagues from the Cell Motility Group of the Institute of Protein Research RAS, discovered a previously unknown mechanism of the regulation of the activity of genes that determine the pluripotent status of the embryonic stem cells. The article was published in Cell Reports. Learn more

Dual Targeting of Cancer Cells with DARPin-Based Toxins for Overcoming Tumor Escape
Researchers of the Laboratory of Molecular Immunology, IBCh RAS, in collaboration with Russian colleagues have shown that the strategy of targeting of anticancer toxins to two different surface antigens on the surface of a cancer cell is effective in the treatment of not only primary solid tumors, but also distant metastases. The proposed approach can serve as a potential therapeutic strategy that surpasses mono-specific targeting strategies in the anti-cancer efficacy. Results of the research are published in Cancers.

Liquid drop of DNA libraries reveals total genome information
Unlike the tightly controlled replication of DNA in living cells, PCR amplification, a “workhorse” of molecular biology, balances between simplicity and accuracy. Conventional “bulk” PCR often yields inefficient and nonuniform amplification of complex templates in DNA libraries, introducing unwanted biases. Researchers from the Laboratory of biocatalysis, Laboratory of proteolytic enzyme chemistry, Laboratory of bioinformatics approaches in combinatorial chemistry and biology, Laboratory of hormonal regulation proteins IBCh RAS together with their Russian and foreign colleagues showed that amplification of single DNA molecules encapsulated in a myriad of emulsion droplets (emulsion PCR, ePCR) allows the mitigation of this problem. The results of this study are published in PNAS. Learn more

Discovery of the novel protein encoded in mammalian mitochondrial DNA polymerase gene POLG
Researchers from Laboratory of bioinformatics approaches in combinatorial chemistry and biology and Laboratory of high-performance screening of biological objects together with colleagues from Moscow State University and University College Cork (Ireland) discovered novel protein POLGARF, which is encoded in alternative reading frame of mitochondrial DNA polymerase POLG mRNA. The results of this study are published in PNAS. Learn more

Multiscale computation delivers organophosphorus reactivity and stereoselectivity to immunoglobulin scavengers
The scientists from the Laboratory of biocatalysis, the Laboratory of proteolytic enzyme chemistry, the Laboratory of bioinformatics approaches in combinatorial chemistry and biology and the Laboratory of hormonal regulation proteins, together with colleagues from EMBL-Hamburg, Moscow State University. M.V. Lomonosov, the Sheffield Institute and the Scripps Research Institute have developed a universal algorithm that makes it possible to create biological antidotes based on biocatalysts, directionally increasing their reactivity, and to predict stereoselectivity. The work was published in the journal Proceedings of the National Academy of Sciences. Learn more
