Different characteristics between northern and southern bank vole populations in Britain, due to differences in haemoglobin types, could affect their ability to adapt to a changing climate. Research by scientists at the Institute of Animal Physiology and Genetics of the Czech Academy of Sciences has shown that northern populations of these small rodents will “borrow” a more favourable haemoglobin variant, critical for adaptation, from populations adapted to living in the warmer conditions of southern England to survive climate warming. The ability to take advantage of the diversity of traits already present in populations and adapt to climate change through them will be critical to the survival of many plant and animal species, including humans.
To monitor the onset and progression of diseases ort he effectiveness of treatment i tis essential to rely on indicators that reflect actual tissue damage and are easily accessible. Scientists from the Institute of Animal Physiology and Genetics CAS have succeeded in isolating small blood particles that are able to carry information about the neurodegenerative Huntington’s disease. Further research into the composition of these particles may help detect damage to otherwise inaccessible organs, including the brain.
14th Tooth Morphogenesis and Differentiation meeting in Prague - Chateau Štiřín is approaching. Join to us to hear exiting stories and to discuss your recent projects related not just tooth but also other oral structures from morphological, evo-devo up to clinical perspective.
Last year’s publication of an updated list of fish sex chromosomes describing the huge variation in different types of sex determination in fish has captured notable attention of the biology and biochemistry community. The work showed that the most well-known XY sex-determination systems, involved also in the determination of sex in humans, and their derivatives have a lower rate of degeneration than the ZW systems. They are therefore more malleable and leave more room for evolutionary processes. The database, created by the scientists from the Institute of Animal Physiology and Genetics CAS in collaboration with colleagues from the University of São Carlos in Brazil, provides fundamental information in the field of evolutionary biology that can be used in conservation genetics and aquaculture as well.
Changing the number or gene content of chromosomes in an organism is assumed to have grave, often fatal, consequences. However, scientists from the Institute of Animal Physiology and Genetics CAS have discovered that some animals do not mind such changes, but instead, they benefit from them by developing novel traits. Thanks to a unique study of asexual reproduction in loaches, experts have described the evolutionary processes of intracellular gene conflict leading to the emergence of new species that are successful in changing environments.
How to reduce the spread of the SARS-CoV-2 virus as much as possible? Experts from around the world are seeking the answer to this question with varying degrees of success. Amidst the peak of the pandemic, national lockdown and implementation of blanket measures, scientists from the Institute of Animal Physiology and Genetics CAS and Masaryk University in Brno, have proven that the SARS-CoV-2 virus did not occur in public areas where people obeyed the safety measures by wearing respirators and disinfecting their hands.
