The study is published in the scientific journal Cancers.

For a cell to grow and divide, it needs to produce new proteins. This also applies to cancer cells. In a new study published in Science Advances, researchers at Karolinska Institutet have investigated the protein eIF4A3 and its role in the growth of cancer cells. The study shows that by blocking or reducing the production of this protein, other processes arise that cause the growth and cell division of cancer cells to cease and eventually die.

Background

For PhD students it is fundamental to improve their reading skills and gain practice in critiquing and appraising research. One common method used for enhancing skills in interpreting research data is participating in journal clubs. Virtual journal clubs can be a safe space where PhD students can improve their presentation and communication skills, they can expand their professional network and practice the skills of interpreting research data.

Karolinska Institutet has signed a collaborative agreement with the Hungarian National Institute of Oncology, NIO. The planned collaboration will primarily take place within the framework of Karolinska Comprehensive Cancer Centre together with Karolinska University Hospital.

Obesity increases the risk of developing cancers of the digestive system and it is the person’s fat mass, rather than size, that is the main obesity-related risk factor for these cancer types, according to a new study published in the journal PLOS Medicine by researchers at the University of Cambridge and Karolinska Institutet.

Researchers at Karolinska Institutet have developed a detailed molecular atlas of the fetal development of the brain. The study published in the top journal Nature is based on so-called single-cell technology and has been done on mice. In this way, researchers have identified almost 800 different cells that are active during fetal development – many times more than previously known.

COMMENTARY: Karolinska Institutet (KI) takes its historical legacy seriously and has therefore taken several initiatives and implemented several measures, to illuminate some of the dark episodes of our history. We take these to be pressing issues, as discussed in an article in Dagens Nyheter on 18 July (E-DN 17 July). KI's more than 200-year history contains aspects that, from today's point of view, would be considered unethical, unscientific, undemocratic and, in some cases, racist.

Both humans and other animals learn quickly about dangers in their environment by observing the behavior of other individuals. Researchers at Karolinska Institutet now show that both rats and humans can use such social information to reactivate memories about threats that have been previously acquired through their own experiences.

Determining who is the biological father of a child is a sensitive subject, but the answer can be crucial in important issues. In a nationwide study published in the Journal of Internal Medicine, researchers from Karolinska Institutet, by using two different models, have been able to show that the proportion of incorrectly established paternities in Sweden is as low as 1.7 percent, a figure that has decreased over time.

The International community must save Dr. Ahmadreza Djalali before it’s too late. Karolinska Institutet backs a call signed by a number of organisations, addressing the European Union, the European state governments, and the United States government to act immediately to secure the release of Dr. Ahmadreza Djalali – an internationally recognized scholar of disaster medicine and KI alumni, wrongfully sentenced to death and in dire need of medical care.

With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic fatty liver disease. The study, which is conducted in mice and human liver tissue, shows that the degeneration of nerves is correlated with the severity of liver pathology. The results are being published in the journal Science Advances.

Joanna Zawacka-Pankau, senior researcher at MedH and Center for Hematology and Regenerative Medicine (HERM) receives the Cathrine Everts Prize of 50.000 SEK for her research on drug repurposing for the improved therapy in TP53-mutated AML.

Children and young people whose mothers had a BMI greater than 30 during early pregnancy are at an increased risk of fatty liver disease. This is shown in a register-based study from Karolinska Institutet and Harvard University published in the journal Journal of Hepatology. As obesity rates increase also in women at a child-bearing age, more and more young people are at risk of developing fatty liver disease, the researchers say.

Rapid diagnosis is crucial in bacterial soft tissue infections to reduce the risk of severe injury or amputation. Vague symptoms and a heterogeneous patient group increase the risk of misdiagnosis. Researchers at Karolinska Institutet and other research institutions have now, with the help of AI, identified a new and very promising biomarker. The study, published in the Journal of Clinical Investigation, may have implications for both diagnosis and treatment.

Researchers at Karolinska Institutet, together with British colleagues, have conducted the largest study to date in search of genetic markers about cluster headache. In the long term, it can hopefully pave the way for more effective treatments. The study is published in the scientific journal Annals of Neurology.

The evolutionary ability to identify sick individuals is crucial to reducing contagion and thereby improving chances of survival. Although most animals have this ability, whether humans have the same behavioural immune system has long been a subject of discussion. Researchers at Karolinska Institutet have now proven that hunter-gatherer groups can, with great certainty, identify the sick from Western Europe. The study was published in Proceedings of the Royal Society B.

On Thursday, 8 July 2021, the European Parliament debated and voted on an awaited resolution to demand that Ahmadreza Djalali – a Swedish-Iranian doctor and researcher sentenced to death – be released from prison in Iran. Passed by a substantial majority of votes, the resolution now calls for the release of Djalali.

In a recently published review article in Nature Reviews Endocrinology, two researchers at the Department of Physiology and Pharmacology at KI, concludes where the field of research is today regarding causes behind and development of, Polycystic Ovary Syndrome (PCOS) and how epigenetic processes can contribute to the development of the syndrome.

Most countries have not introduced nationwide prostate-cancer screening, as current methods result in overdiagnoses and excessive and unnecessary biopsies. A new study by researchers at Karolinska Institutet in Sweden, which is published in The New England Journal of Medicine, indicates that screening by magnetic resonance imaging (MRI) and targeted biopsies could potentially cut overdiagnoses by half. The results are presented today at the European Association of Urology Congress.

In March 2020, thousands of researchers across the globe joined forces to answer the question of why some COVID-19 patients develop a severe, life-threatening disease, while others manage with mild or no symptoms. A comprehensive summary of their findings to date, based on the analyses of nearly 50,000 patients and published in Nature today, reveals 13 genetic regions that are strongly associated with infection or severe COVID-19.

In addition to Joana Pereira at the Division of Clinical Geriatrics, four more people have been appointed as new research group leaders at NVS during the spring.
