Tumour monitoring using liquid biopsy

Liquid biopsy, the analysis of cancer biomarkers and circulating tumour cells in body fluids such as blood, is revolutionising the diagnosis and monitoring of cancer. It has also been possible to expand circulating tumour cells from the blood under laboratory conditions. It is expected that in the future, liquid biopsy will be able to precisely characterise tumour cells at every stage of a cancer.

Personalised therapies for treating metastasing breast cancer

Breast cancer is characterised by broad genetic diversity. Successful treatment is made even more difficult by the fact that, in advanced breast cancer, the properties of metastases often differ significantly from the primary tumour. The Heidelberg CATCH study is now collecting genetic profiles from patients' metastasis tissue samples, which can be used to tailor therapy to individual requirements.

Epigenetics – heritable traits without changing the DNA sequence

Epigenetics, i.e. the inheritance of traits that does not involve a change in the DNA sequence, was once a controversial subject that has since become a central focus of biological research. Epigenetic inheritance is now studied by numerous national and international research programmes. Many cellular regulatory and differentiation processes are controlled by epigenetic mechanisms that take place on different levels.

Advances in the study and treatment of liver diseases

Liver diseases are often underestimated despite being quite common and potentially having serious and even life-threatening consequences, especially in chronic cases. The most common causes of liver diseases are hepatitis viruses, excessive alcohol consumption, and obesity; congenital or autoimmune liver diseases are quite rare. Thanks to advances in medical research, diseases such as hepatitis B and C can be treated effectively.

Cancer therapy and cancer diagnostics

Thanks to improved diagnostics and therapy, today’s cancer patients can live considerably longer than patients several years ago. Nevertheless, some cancers, especially the strongly metastatic ones, are difficult to treat. Therapies targeting immune cells or cancer stem cells could potentially improve the current situation.

The 15-year history of RNA interference is not short on dramatic effects. It begins with the unexpected discovery and publication of the process of post-transcriptional gene silencing in 1998 for which the two Americans Andrew Fire and Craig Mello were awarded the Nobel Prize in Physiology or Medicine just eight years after their discovery. In 2001 Thomas Tuschl succeeded in switching off genes in human cells with small synthetic pieces of RNA…

Adult stem cells hope for regenerative therapies

Adult stem cells have the lifelong ability to generate new specialised cells. They secure the continuous replenishment of cells therefore enabling the constant replacement of dying cells with new ones. Progress in the characterisation isolation and specific differentiation of adult stem cells over recent years raises hopes for the future use of the cells in the therapy of degenerative diseases. Knowledge about adult stem cells also has the…

New trends in the field of immunology

B- and T- lymphocytes along with macrophages have long been regarded as the most important cells of the human immune system and have been a major focus of research. This has now changed and it is now the dendritic cells that are regarded as the major components of the adaptive immune system. Research into innate immune defence mechanisms has become more important due to the discovery of the role of Toll-like receptors as first-line of defence.

Genetic diagnostics technology reaches the limits of what is medically reasonable

Rapid progress in sequencing technologies is poised to set the imagination of biomedical researchers on fire. Experts now believe that progress is about to make possible what seemed to be utopian a few years ago – it seems likely that it will soon be possible to sequence the human genome in only a few minutes and store and automatically analyse it using tiny automates. However, is everything that is technically feasible also reasonable?
