Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work shows that cells use two different strategies to precisely control inflammatory genes and thus precisely regulate the inflammatory response.

About five percent of lung adenocarcinomas, one of the most common forms of lung cancer, are driven by a faulty fusion of two genes, EML4 and ALK. This fusion results in different variants, and until now, clinicians have treated all patients with these fusions the same way. However, new research led by scientists from the German Cancer Research Center (DKFZ) and Stanford University shows that not all fusion variants behave alike.

Researchers have discovered part of the answer to why some people with obesity or diabetes develop fatty liver disease while others remain healthier.

This can lead to tissue damage, inflammation and serious metabolic disorders.

The 2020 Nobel Prize in Chemistry was awarded for the development of CRISPR/Cas9, a method also known as “gene scissors”, which enables researchers to better understand how human cells function and stay healthy. Researchers at the University of Stuttgart have further developed CRISPR for this purpose. They present their CRISPRgenee method in Cell Reports Methods.

The cellular environment of a tumor can either support or sabotage recovery.

They play a crucial role in rapid information processing in the brain.

Every brain tumor is made up of cells in successive stages of activation. Researchers have now analyzed the individual structure of these activation pyramids in malignant brain tumors.

The hope is that this will permanently freeze cancer cells in a dormant state and thus halt tumor growth.

However, EBV can sometimes cause cancer, and this pathogen also appears to play an important role in multiple sclerosis and other autoimmune diseases. Researchers have discovered that EBV increases the ability of infected immune cells to migrate. In this way, the pathogen promotes its spread in the body – a discovery that may have therapeutic implications.
