The spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a basic requirement for producing proteins. Researchers at the Heidelberg University Biochemistry Center (BZH) have succeeded for the first time in depicting a faultily “blocked” spliceosome at high resolution and reconstructing how it is recognized and eliminated in the cell.

Mini-organs and multi-organ chips - where lab mice may soon retire

Farewell to animal testing? Life sciences researchers in BW are pioneering innovative methods to replace animal experiments, reduce the number of animals used and refine the procedures and conditions under which animals are kept. These are the guiding principles of the 3Rs principle. Developing cutting-edge models and establishing a robust 3R network, not only shapes the future of research but also improves the quality of scientific outcomes.

Researchers at University of Galway, the Heidelberg Institute for Theoretical Studies (HITS) Heidelberg University, and Heidelberg University Hospital have created digital babies to better understand infants’ health in their critical first 180 days of life. The international team created computer models that simulate the unique metabolic processes of each baby. The models can help to better understand rare metabolic diseases.

Researchers from the Max Planck Institute for Biology Tübingen broke new ground by demonstrating that an HMG-box gene in brown algae is crucial for determining male sex. This breakthrough significantly expands our understanding of sex-determination mechanisms in eukaryotic organisms. Until now, master sex-determination genes had been identified in only a select number of animals and plants.

Using organoids to gain a better clinical understanding of pancreatic cancer

Prof. Dr. Alexander Kleger carries out translational research at Ulm University Hospital to gain a better understanding of pancreatic ductal adenocarcinoma (PDAC) and develop individualised treatments. He and his team are using organoid models and stem cell-based systems and have succeeded in simultaneously cultivating all three main cell types of the pancreas from pluripotent stem cells.

More than seven million people in Germany suffer from diabetes. At the same time, research into drugs to treat this widespread disease is still difficult. Scientists led by Prof. Dr. Peter Loskill from the NMI Natural and Medical Sciences Institute and the Faculty of Medicine of the Eberhard Karls University of Tübingen have now developed a technique that significantly improves the view at the molecular and cell biological level in the pancreas.

Heidelberg scientists unveil genetic programmes controlling the development of cellular diversity in the cerebellum of humans and other mammals. The research results have now been published in the journal Nature.

Artificial cytoskeleton made of DNA for synthetic cells

The physicists Prof. Dr. Kerstin Göpfrich and Prof. Dr. Laura Na Liu want to understand life from the bottom up. They intend to do this by constructing an artificial cell. However, rather than natural protein building blocks, they are using 3D-DNA structures as construction material. The first step involved creating an artificial cell skeleton that dynamically assembles and disassembles like the biological model and can transport vesicles.

Drug screening for children with cancer using patient-specific miniature tumours

Standard drugs often don’t work in children and adolescents with recurrent cancer. Researchers from the Hopp Children's Tumour Centre (KITZ) and the German Cancer Research Center (DKFZ) in Heidelberg have been looking to open up new therapy options for those affected, and have cultivated individual miniature tumours from biopsy samples to test the effectiveness of a variety of drugs within a few weeks.

Centromeres, the DNA sections often found at the center of the chromosomes, display enormous interspecies diversity, despite having the same vital role during cell division across almost the entire tree of life. An international team of researchers has discovered that the variation in centromere DNA regions can be strikingly large even within a single species. The findings, now published in the journal Nature, shed light on the molecular…

The recently established ITCC-P4 gGmbH provides academic institutions and pharmaceutical companies with a comprehensive repertoire of modern laboratory models of pediatric tumors. The aim is to systematically test new treatment options for children and adolescents with cancer and to contribute data to regulatory approval processes in order to make the development of new cancer therapies for children and adolescents more attractive.

Heidelberg scientists succeed in boosting the efficiency of CRISPR/Cas9 and related methods and modifying initially inaccessible DNA sequences.

A pioneering technique developed by the Prevedel Group at EMBL allows neuroscientists to observe live neurons deep inside the brain – or any other cell hidden within an opaque tissue. The technique is based on two state-of-the-art microscopy methods, three-photon microscopy and adaptive optics. The paper reporting on this advancement was published on 30th September 2021 in Nature Methods.

The many faces of the epigenetic regulator MOF

Epigenetic modifications play a crucial role in coordinated gene transcription, and are required for a fertilised egg cell to be able to develop into an organism with different cell types. Dr. Asifa Akhtar from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg has been studying the essential epigenetic regulator protein MOF for 20 years.

Under certain conditions, our immune system can efficiently fight off infectious diseases and cancer. T cells, especially the gamma delta T cell type, play an important role in this. The issue is that this cell type is extremely infrequent in the human body. Researchers at the University Hospital Tübingen, the University of Heidelberg and the European Molecular Biology Laboratory (EMBL) have now succeeded in finding the cause for the formation of…

The human proteome the next major goal

The “Human Proteome Project”, a ten-year global initiative that is making a systematic effort to map all human proteins, has moved from the planning to the experimental stage. How significant and how effective the project will be depends on how much the resources offered are used by proteome researchers and on the data that the researchers bring into the project.

Systems biology understanding complex biological systems

Systems biology studies complex interactions within biological systems on the genome proteome and organelle level. Many techniques from the fields of systems theory and associated fields can be used to gain an understanding of the behaviour and biological mechanisms of cellular systems.
