Epigenetics provides new insights into the pathogenesis of lymphoma

05.10.2016

Cancer cells have a different DNA methylation pattern from that of healthy cells. These patterns can be used to explain tumour-specific deviations in gene expression and to identify biomarkers for the detection of tumours, as well as associated prognosis and treatment planning. This is all possible thanks to epigenetics. Epigenetics looks at special regulation mechanisms, such as DNA methylation and histone modifications, which determine the gene expression pattern of different types of cell and are passed on to daughter cells, without there being any specific changes to the DNA base sequence. Using this technology, it is now also possible to identify the original tumour cells, by comparing them with healthy cells.

In collaboration with scientists from the Austrian Institute of Technology (AIT), the University of Cambridge and the University of Southern California (USC), molecular biologist Melanie Hassler from the working group led by Gerda Egger (Department of Pathology at MedUni Vienna, Division of Experimental Pathology, Head: Lukas Kenner) has analysed the methylation pattern of Anaplastic Large Cell Lymphoma (ALCL), an aggressive non-Hodgkin lymphoma that primarily affects children and young adults. ALCL is a very aggressive form of leukaemia, which usually manifests itself as tumours in the lymph nodes, skin, lungs, liver and soft tissues. 


Epigenetics provides new insights into the pathogenesis of lymphoma

However, in the paper that was recently published in the leading journal "Cell Reports", the researchers were able to use the methylation pattern to show that – contrary to what we previously thought – ALCL resembles early T-cell development in the thymus gland, which is part of the lymphatic system. Moreover, due to epigenetic silencing, these lymphomas lack important T-cell-specific factors for cell development and differentiation. Hassler explains: "Certain drugs that interfere in the methylation programme of cancer cells could be used in future to adjust the methylation pattern of ALCL cells to that of healthy T-cells, thereby arresting tumour growth."

A better understanding of ALCL

Egger: "The results of this study have given us a better understanding of the development of ALCL in children and adolescents, so that in future we will be able to attack cancer cells in a targeted way, using epigenetic therapies. Furthermore, decoding of the methylation pattern of ALCL provides us with a basis for establishing biomarkers in the area of personalised and translational medicine." Gerda Egger heads up the epigenetics working group at the Department of Pathology and is Deputy Director at the Ludwig Boltzmann Institute for Applied Diagnostics.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
