New findings reveal an advanced, unexpected two-way communication between the function and organization of chromosomes in the cell nucleus. Previous research shows that the organization of chromosomal DNA into loops regulates gene reading (transcription) and chromosome copying (replication). The new results show that, in turn, transcription and replication control chromosome looping, thus revealing a new interplay known to be important in avoiding diseases, such as cancer.
News
Researchers at Karolinska Institutet have mapped how the parasite Trypanosoma cruzi forms new variants that are more effective at evading the immune system and causing disease. Their findings can give rise to new methods for diagnosing, preventing and treating Chagas disease, which affects millions of people in Central and South America, causing thousands of deaths every year. The study is published in the journal eLife.

While the large proportion of our genome that does not instruct our cells to form proteins has been harder to study than protein-coding genes, it has been shown to have vital physiological functions. Scientists at Karolinska Institutet have now developed new high-precision tools able to identify what these noncoding sequences do. The study, which is published in the journal Nature Genetics, may eventually contribute to the development of new, targeted drugs.
News
Using a technique called spatial transcriptomics, researchers at Karolinska Institutet have analysed the gene expression in the mouse colon and created a map showing where in the tissue individual genes are expressed. When they superimposed previously known human transcription data onto the map, the researchers gained new insights into inflammatory bowel disease (IBD). The study is published in the journal Nature Communications.

An international metastudy led by researchers at Karolinska Institutet has identified a specific gene variant that protects against severe COVID-19 infection. The researchers managed to pinpoint the variant by studying people of different ancestries, a feat they say highlights the importance of conducting clinical trials that include people of diverse descents. The results are published in the journal Nature Genetics.

Very few proteins in the body have a change that makes them unique compared to the corresponding proteins in Neanderthals and apes. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden have now studied one such protein, glutathione reductase, which protects against oxidative stress. They show that the risk for inflammatory bowel disease and vascular disease is increased several times in people carrying the Neanderthal variant.
