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.

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

Toxicologists from the University of Konstanz have found that the protein p53 continuously protects our cells from tumorigenesis by coordinating important metabolic processes that stabilize their genomes.

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.

Targeted RNA editing with the body’s own enzyme activity

Completely new possibilities for research and gene therapy became available following the development of the CRISPR/Cas method for targeted modification of the genome. However, treatment with molecular scissors is not without risk as potential errors are stored in the genome forever. Scientists from Tübingen have developed an alternative method in which the intervention takes place at the RNA level using the body's own enzymes and is thus…

Stocktaking and recommendations for action: the BBAW’s fourth gene technology report

In the new gene technology report, the interdisciplinary working group of the Berlin-Brandenburg Academy of Sciences (BBAW) takes stock of gene technology developments in Germany during the past few decades, and discusses the societal, legal and ethical challenges associated with these technologies in the future. The report is highly topical due to the controversy surrounding the ruling of the European Court of Justice on CRISPR/Cas9 genome…

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.

The working group around Dr. Philipp Rathert at the Institute for Biochemistry and Technical Biochemistry investigates the regulation of epigenetic networks of certain cancers and ways of treating them. The working group published its new findings in April.

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.

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.

Bioanalysis techniques for the characterization of biological material

Science constantly provides researchers with new challenges biologists and bioanalysts have to deal with and which come from sources as varied as the ever increasing number of resistant pathogenic bacterial strains or the famine conditions in Third-World countries. In the search for scientific truths bioanalysis is the development optimization and application of the entire range of analytical methods available. However we need to keep in mind…

Retroviruses from infectious agent to therapeutic assistant

Viruses are infectious particles that use the machinery and metabolism of a host cell to replicate. Despite some similarities with accepted forms of life viruses are not considered as such. The family of retroviruses is particularly known for its most notorious representative i. e. the human immunodeficiency virus HIV which leads to AIDS and for which no cure or effective vaccine is currently available. However retroviruses are not only of…

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.

Therapeutic viruses against tumours and metastases

Viruses can overcome cell barriers and transfer information to their host cells. They know how to make their host cell’s infrastructure work for them. This makes them excellent biotechnological tools, which a research group from the Fraunhofer IGB in Stuttgart is using to its advantage. The team is developing a therapeutic virus that not only recognises and fights tumours, but also has the potential to reach metastases.

Researchers from EMBL and Heidelberg University Hospital combine high-resolution imaging to observe the infection process in cell nuclei, opening the door for new therapeutics.

A new method allows stem cells and cancer stem cells to be studied at the single cell level and the resulting cell clones to be traced directly. Studying thousands of individual cells in parallel, the researchers combined the analysis of the genomic cancer mutations with the associated expression profiles.

Whole genome sequencing for diagnosing rare diseases

Grouped together, rare diseases are by no means a rare phenomenon; however, they are rarely correctly diagnosed and rarely properly treated. In most cases, there is no effective medication available. Rare disease centres staffed by experts have been set up in many German cities to speed up the often long and painful search for the right diagnosis and treatment. Whole genome sequencing is a component of general healthcare, used to identify…
