  • Toxin from black mamba venom inhibits growth of glioma cells selectively expressing ASIC1a channels science news VII.20

    Gliomas are fast growing and highly invasive brain tumors, characterized by tumor microenvironment acidification that drives glioma cell growth and migration. Channels containing Acid-sensing Ion Channel 1a subunit (ASIC1a) mediate amiloride-sensitive cation influx in late stage glioma cells, but not in normal astrocytes. Thus, selective targeting of ASIC1a can be a perspective strategy for glioma treatment.

  • Start codon context and occurrence of AUG codons in the beginning of protein coding open reading frames co-evolve science news VII.17

    Researchers from IBCh RAS together with their international collаborators discovered an evolutionary link between efficiency of start codons and the probability of AUG codon occurrence in the 5'-end parts of protein-coding sequences. When start codons are inefficient the next AUG codon is more likely to be found in the same reading frame. At the same time in case of highly efficient start codons, the next AUG codon is more likely to be found in alternative frames. They also have shown that weak initiation at the first starts is associated with the synthesis of shortened proteoforms as a result of initiation at the second starts.

  • New technology promises to revolutionize nanomedicine science news VII.16

    A collaboration of scientists from the Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry, the Moscow Institute of Physics and Technology and Prokhorov General Physics Institute of the Russian Academy of Sciences have developed a breakthrough technology to resolve a key problem that has prevented the introduction of novel drugs into clinical practice for decades. The study was published in Nature Biomedical Engineering and featured in the journal’s News & Views section.
