As cancer progresses, the tumor cells continually change, ultimately resulting in a tumor consisting of a large number of different cell clones with different characteristics. This is referred to as "tumor heterogeneity". In many cases, the cancer cells become resistant to the treatments available.

Treatment resistance is a central problem in the treatment of cancer. Bone and soft tissue tumors – known as sarcomas – in adolescents and young adults often stop responding to treatment too. This is because cancer cells develop a large number of new characteristics as the disease progresses and often become resistant to drugs that were originally effective.

Pharmacogenomics enables individualised drug prescription

Every person is unique, and their reaction to medications can be just as individual. For this reason, unexpected side effects occur time and again with common drugs, sometimes with life-threatening consequences. At the Dr. Margarete Fischer-Bosch Institute for Clinical Pharmacology (IKP) in Stuttgart, the influence of hereditary factors on these harmful reactions is being investigated in order to enable individualised therapies.

To diagnose an infection with the coronavirus, usually a throat swab is taken and genetic viral material detected by using a highly sensitive PCR. To date, more than 65 million of these tests have been performed in Germany alone. Due to the massive increase in testing worldwide and simultaneous loss of production, there was a significant shortage of test materials in the early stage of the pandemic.

Faster to single cells using miniature grinder

Tissue cells are needed for medical diagnostics, cell therapies and tissue engineering, among other things. A novel tissue grinder gently and automatically dissociates cells from tissue. In November 2020, the newly founded biotech company Fast Forward Discoveries GmbH (FFX) delivered its first tissue grinders to customers.

So-called silent mutations have no effect on the composition of a protein. They are therefore not considered to promote cancer. However, scientists from the German Consortium for Translational Cancer Research (DKTK), partner site Essen, now describe in a case of kidney cancer an overlooked silent mutation with a major impact on prognosis.

Whole blood model enables development of early warning system for sepsis

Sepsis is a life-threatening disease that can be treated all the more successfully the faster therapy is initiated. It is not just the infection itself that is so dangerous, but a dysregulated response of the immune system. Physicians at Ulm University Hospital have now developed an animal-free test system that can be used to research the disease and develop innovative diagnostic tools to quickly assess a patient's sepsis risk and optimise…

An international research team involving the universities of Paraná and Tübingen has developed a rapid test that can reliably identify Covid-19 antibodies in the blood within minutes. As the researchers report in the journal ACS Sensors, the new process is based on a simple measuring principle making it easy to carry out without expensive instruments, and is therefore suitable for use at mobile testing centers or by laboratories.
