Known as the power plant of the cell, mitochondria are essential to human metabolism. Human mitochondria consist of 1,300 different proteins and two fatty biomembranes. The vast majority of mitochondrial proteins are produced with a cleavable transport signal and have to be actively transported into the mitochondria.

Researchers from Konstanz and Zurich have deciphered a biochemical mechanism that ensures that newly formed proteins are processed correctly when they leave the cell's own protein factories. This solves a decade-old puzzle in protein sorting.

Tübingen researchers describe connection between action and feeling of authorship - finding sheds light on delusions of external control in schizophrenia

Proteins have characteristic amino acid sequences, the analysis of which is fundamental for research and medicine. These can be decoded; however, so-called protein sequencing is expensive and time-consuming. A large-scale research project led by Prof. Dr. Jan Behrends from the Institute of Physiology at the University of Freiburg now aims to establish a new technology for protein sequencing using nanopores, which will be rapid and cost-effective.

Konstanz researchers discover the function of a previously unexplored protein: In three characteristic steps, "C12orf29" links the ends of RNA strands. Proteins that perform this kind of RNA ligation were previously unknown in humans. The results of the study suggest that it is important for RNA repair during cellular stress.

TuCAN - innovative diagnostic procedure for neuropsychiatric disorders

Neuropsychiatric disorders are often diagnosed late and have a negative impact on quality of life. Diagnosing the disease at an early stage is vital to be able to help those affected by offering them treatment adapted to their specific requirements. This is what the TuCAN project in Tübingen aims to achieve through the early and differential diagnosis of neuropsychiatric disorders.

How can camera images be used during minimally invasive surgeries to assess whether the operated organ is sufficiently perfused with blood? Scientists from the German Cancer Research Center (DKFZ) and the Städtisches Klinikum Karlsruhe have now succeeded in automatic monitoring of ischemia during a kidney surgery using only the optical properties of the tissue and not relying on injection of contrast agent.

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

Researchers of the University of Freiburg introduce biosensor for the nucleic acid amplification-free detection of SARS-CoV-2 RNA.

From human intestines to the bottom of the sea: Microorganisms populate nearly any habitat, no matter how hostile it is. Their great variety of survival strategies is of huge potential in biotechnology. Most of these organisms, however, are unknown, because they cannot be cultivated.

Researchers have created a tool that maps how breast cancer grows in previously unseen detail, and highlights how the cells around the tumour may be the key to controlling the spread of disease. The new technology can trace which populations of breast cancer cells are responsible for the spread of the disease, and for the first time highlights how the location of cancer cells could be as important as mutations in tumor growth The new study is…

Hummingbird Diagnostics GmbH - 22/09/2022

The great potential of blood-based microRNA analyses

"The early bird catches the worm", is an apt description of what motivates Hummingbird Diagnostics GmbH from Heidelberg. The medium-sized biotechnology company analyses special biomarkers in blood, so-called microRNAs, in order to diagnose diseases at an early stage and to be able to make forecasts about the course of the disease and the success of therapy.

Tuberculosis is one of the leading causes of death worldwide, with an estimated 1.4 million deaths and ten million people infected annually. Resistant and multidrug-resistant (MDR) variants of the tuberculosis pathogen Mycobacterium tuberculosis pose a major threat to tuberculosis control and global health.

Changes known as epigenetic modifications play an important role in cancer development, among other things. Being able to analyze them quickly and reliably could, for example, contribute significantly to the further development of personalized therapy.

The European Research Council is funding a large-scale proof-of-concept study on a new genome sequencing method called “Haplotagging”. Haplotagging is a new method for sequencing our genome with superior quality and faster speed, developed by group leader Frank Chan and his team at the Friedrich Miescher Laboratory at the Max Planck Campus, Tübingen, Germany.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases. Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

microRNA as a prognostic biomarker - 13/01/2022

Heart attack diagnosis: fast and unambiguous thanks to artificial intelligence

People that arrive in emergency rooms with chest pain require swift action in order to rule out a heart attack or to initiate vital life-saving therapy. However, despite many advances, current tests are not yet optimal: they either take hours or produce false-positive results. Researchers at Heidelberg University Hospital are now using AI in an approach that takes microRNAs from a blood sample to specifically diagnose ‘acute coronary syndrome’.

Genetic alterations that promote the development and spread of tumors are difficult to identify. This is especially true for mutations in the non-protein-coding regions of the genome, which include all important regulatory sequences. Scientists at the German Cancer Research Center have now published an algorithm that detects cancer drivers in both the protein-coding and non-coding regions of the genome.

Parkinson's disease is characterised by a slow, progressive loss of nerve cells in certain brain areas. The disease is still incurable and the exact causes are unclear. The dopamine deficiency in the brain can only be controlled to some extent in the initial phase of the disease. Basic research is being conducted in an attempt to unravel the mystery of Parkinson's disease.

In multiple myeloma, a cancer of the bone marrow, relapse almost always occurs after treatment. Initially, most patients respond well to therapy. However, as the disease progresses, resistant cancer cells spread in the bone marrow, with fatal consequences for the patients.

nanodiagBW: using nanopores to create completely new diagnostic possibilities

Modern medicine has a wide range of molecular diagnostics at hand. In the next decade, this will increasingly be supplemented by prognostic methods. The BMBF Cluster of the Future finalist, nanodiag BW, is developing prognostic methods to identify epigenetic factors for diseases through a new type of bioanalytics – single molecule analysis in nanopores – which would make it possible to take personalised prevention approaches.

Furtwangen University publishes the world’s first molecular biological study on bacterial contamination of slit lamps. Slit lamps are among the most important tools used by ophthalmologists and opticians. They allow selected areas of the eye to be magnified and examined for diseases.

Scientists of the Translational Lung Research Center Heidelberg (TLRC) and the German Cancer Research Center (DKFZ) have discovered a new link between excessive airway mucus and chronic airway inflammation that is characteristic of cystic fibrosis and chronic obstructive pulmonary disease (COPD). The researchers showed that mucus in the airways reprograms certain cells of the immune system.
