Nanoliposomes pave the way for treatment of rare genetic diseases
Indication of new nanoGLA therapy. We demonstrate its composition and structure by cryomicroscopic imaging. NanoGLA has been injected into mice and has orphan drug designation. Credit: ICMAB An international research team has developed a new nanotechnology-based therapy called nanoGLA for the treatment of Fabry disease. This new treatment has shown significant efficacy in preclinical studies. The study was published in…

Origins of the genetic code: Study finds textbook version needs revision
In this AI-generated illustration of Earth at the dawn of life, distant volcanoes tower over shallow pools of water. The earliest life forms may have evolved in such an environment. Credit: AI generated, Joanna Masel Despite their incredible diversity, nearly all life forms, from bacteria to blue whales, share the same genetic code. How and when this code was created…

Studying membrane proteins using genetic code extensions
Protein labeling strategy. Credit: Chemical Reviews (2024). DOI: 10.1021/acs.chemrev.4c00181 Over the years, chemical biology techniques have made important contributions to the study of integral membrane proteins. An important modern approach is genetic code expansion (GCE), which allows proteins to be directly modified in living cells to confer customized properties. Professor Irene Coyne of the University of Leipzig is a pioneer…

Team investigates population genetic characteristics of two hybrid crucian carp lines
Central linkage network based on Tf alleles. Credit: Reproduction and Breeding (2024). DOI: 10.1016/j.repbre.2024.07.002 Crucian carp (Carassius auratus) is a common freshwater fish in China, and its farming mainly relies on artificially bred superior varieties. A hybrid strain derived from Carassius cuvieri (♀) × C. auratus red var. (♂) (HFJ) and new homodiploid crucian carp-like lineages derived from carp (♀)…

UN summit approves fund to share the benefits of sequenced genetic data from nature
Credit: Pixabay/CC0 Public Domain On Saturday, the United Nations Summit on Nature in Colombia agreed to create a fund to share the benefits of genetic data sequenced digitally from animals and plants with the communities from which it originates. Such data, many of which come from species found in poor countries, are used particularly in medicines and cosmetics, and can…

Advanced genetic techniques and microscopy provide new insights into the symbiosis of anaerobic ciliates and methanogens
AP, representatives of the studied anaerobic ciliates and their respective methanogenic endosymbionts, please refer to the study for a complete description. Credit: Charles University Recent studies have revealed important details about the relationship between anaerobic ciliates and methanogenic archaea. This relationship has fascinated scientists for decades. Researchers from Charles University School of Science and the University of Rhode Island used…

Genetic tracing at South China Seafood Market further supports animal origin of COVID-19
Credit: CC0 Public Domain A new international collaborative study has published a list of wild animal species available in markets where SARS-CoV-2, the virus that caused the COVID-19 pandemic, likely emerged in late 2019. The study is based on a new analysis of metatranscriptomics data published by the Chinese Center for Disease Control and Prevention (CDC). The data came from…
