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
The discovery of four genes of the Noggin family in lampreys is consistent with the hypothesis of two rounds of genomic duplications in vertebrate ancestors
Researchers from the Laboratory of Molecular Bases of Embryogenesis, together with a colleague from the Severtsov Institute of Ecology and Evolution, described for the first time four genes of the Noggin family in the oldest representatives of vertebrates - lampreys, and compared their structure, expression and some functional features with those of the known genes of this family in other vertebrates. As a result, it was concluded that the entire set of the data obtained is in the best agreement with the hypothesis of two successive rounds of duplications of the ancestral genome of invertebrates that occurred at the earliest stage of vertebrate evolution. The work was published in the new journal of Nature Publishing Group - Communications Biology. Learn more
