An international team of scientists that included researchers from ITMO University developed a software tool that makes it possible to quickly and efficiently find similar parts in the genomes of different animals, which is essential for understanding how closely related two species are, and how far they have evolved from their common ancestor. The research was published in Giga Science.
Modern bioinformatics allows us to take a look into the past and find out when certain species diverged during evolution, which of them still are genetically close to each other, and which are not. An international team of researchers, which, among others, includes the academic supervisor of ITMO University’s Laboratory of Genomic Diversity and researchers from the University of Copenhagen, Barcelona Institute of Science and Technology, and other research centers from all over the world, analyzed the genomes of extinct and living lions. They managed to determine when the divergence took place, as well as come to several other conclusions on genetic diversity of the modern lion population in India. The results are published in the journal Proceedings of the National Academy of Sciences of the United States of America.
In 2020, ITMO University has launched the Laboratory of Genomic Diversity under the academic supervision of the renowned American scientist Stephen J. O’Brien. This new department is to become an important Russian center of bioinformatics, where scientists will work on collecting genomes of different living organisms and studying genetic diversity of animals and people. This work should help in fighting many diseases while also providing a better understanding of the ways in which biodiversity changes on our planet. ITMO.NEWS met with the coordinators of this emerging laboratory and learned what research they plan to do in the near future.
Scientists Develop Algorithm for Researching Evolutionary History of Species with Whole-genome Duplications
An international team of scientists created an algorithm for studying the evolutionary history of species with whole-genome duplications, chiefly yeast and plants. The program can be used to analyze the genetic information about these species and make conclusions on how whole-genome duplication took place and why it secured a foothold in the process of evolution. The article was published in Oxford Bioinformatics, one of the leading titles in the field of Computer Science.
It was not so long ago that bioinformatics specialist Alexey Komissarov joined the team of ITMO University’s SCAMT Laboratory, where he conducts the assembling and annotation of complex genomes of animals and humans. At the end of 2019, the Applied Genomics research group, which he heads, received a grant from the Russian Foundation for Basic Research. Their project will be dedicated to the analysis of genes and proteins in nerve cells of lampreys, which could help in the fight against neurodegenerative diseases. ITMO.NEWS met the scientist to find out more about his research.
Vladimir Uliantsev, head of ITMO University’s International Laboratory “Computer Technologies,” has presented the lecture "Bioinformatics: How genomic data helps study the origin of people and the mechanisms of disease development" at the New Holland Island Open Lecture Hall. Those who came to the event learned how today’s scientists acquire genome data, the role of programmers in that process, and what makes the results of that research so valuable. Find the highlights of last week’s lecture in the article below.
At the Intersection of Sciences: Bioinformatics Specialist Nikita Alexeev on Challenges of DNA Research
Nikita Alekseev is a senior researcher at ITMO University’s Information Technologies and Programming Faculty and a member of the ITMO Fellowship program. He has recently come back to St. Petersburg after spending several years on bioinformatics research in the United States. In this interview, he shared with us his views on bioinformatics and talked about his career.
Scientists have carried out the first-ever analysis of the full genome of representatives of Russia’s various ethnic groups. Using specialized software, they traced the development history of several of these groups. In the future, the resulting data can be used in other valuable research, such as in identifying genetic risk factors in various populations of Russian people. The results of this study were published in Genomics.
How can one of most widespread materials on the Earth help cure cancer? In what ways are people similar to pigeons? Why oxidize graphene atoms? And why do genes constitute only 20% of the human genome? Scientists gave answers to these and other questions during the recent Science Slam in St. Petersburg; ITMO.NEWS summarized the key points of their presentations.
