Groundbreaking research into the fundamental mechanisms of genetics and a novel understanding of how brain tumors thrive are being recognized with prestigious awards. Developmental biologists Davor Solter and Azim Surani will receive the 2026 Paul Ehrlich and Ludwig Darmstaedter Prize on March 14 at Frankfurt’s Paulskirche for their discovery of genomic imprinting, a process that fundamentally altered our understanding of heredity. Simultaneously, neurologist Varun Venkataramani is being honored for his pioneering work demonstrating how malignant brain tumors harness the electrical activity of the brain to fuel their growth.
The discoveries, announced by the Paul Ehrlich Foundation, represent significant leaps forward in both developmental biology and cancer neuroscience. Genomic imprinting, in particular, has opened entirely new avenues of research into inherited diseases and the complex interplay between genes and environment. Venkataramani’s work offers a potential new target for therapies aimed at disrupting tumor growth.
For decades, the prevailing view in genetics held that individuals inherit two active copies of each gene – one from each parent. However, in 1984, Solter and Surani independently challenged this dogma. Their research revealed that, for some genes, only one copy – either the maternal or paternal – is actively expressed, while the other is permanently silenced. This phenomenon, termed genomic imprinting by Surani, demonstrated that inheritance isn’t simply about the genes we receive, but also how those genes are expressed.
Unraveling the Mystery of Genomic Imprinting
Solter and Surani arrived at their conclusions through parallel research, utilizing a cell nucleus transplantation technique developed by Solter. Their experiments with mouse embryos showed that embryos containing only maternal or only paternal genetic material were not viable, confirming the necessity of genetic contributions from both parents. This finding distinguished mammals from species capable of parthenogenesis – reproduction from unfertilized eggs, like some ants, bees and lizards. The key, they discovered, lies in epigenetic imprints – molecular tags attached to DNA that selectively switch genes on or off.
“This discovery was a turning point in modern genetics,” explained Prof. Thomas Boehm, Chairman of the Scientific Council of the Paul Ehrlich Foundation. “It showed that our phenotype is not determined by genotype alone, but also shaped by epigenetic marks.”
Genomic imprinting isn’t merely a curiosity of developmental biology; it plays a crucial role in healthy embryonic development, balancing resource allocation between mother and fetus. Approximately 1% of human genes are imprinted, and many are involved in signaling pathways that influence health and disease throughout life. The understanding of genomic imprinting has given rise to the field of epigenetics – the study of how gene expression is regulated without altering the underlying DNA sequence – and has already informed the development of targeted cancer therapies.
Tumors ‘Tap’ into Brain’s Electrical Network
While Solter and Surani’s work illuminates the fundamental processes of inheritance, Varun Venkataramani’s research sheds light on the aggressive behavior of brain tumors. Most brain tumors, known as gliomas, originate from glial cells – cells that support and nourish neurons – rather than the neurons themselves. Venkataramani’s research revealed a surprising mechanism driving glioma growth: these tumors form synapses, or connections, with healthy neurons, effectively “tapping” into the brain’s electrical signaling network to accelerate their proliferation and spread.
Over the past decade, Venkataramani and his colleagues have rigorously validated this finding, establishing a new field known as cancer neuroscience. This research has opened up a promising therapeutic avenue: disrupting the tumor’s access to neural signaling. A Phase II clinical trial is currently underway to test this approach, offering potential hope for patients with aggressive brain cancers.
The 2026 Paul Ehrlich and Ludwig Darmstaedter Prize, endowed with €120,000, recognizes the profound impact of these discoveries. The awards underscore the importance of basic research in unraveling the complexities of life and paving the way for innovative medical treatments.
The future of genomic imprinting research lies in further elucidating the role of epigenetic modifications in disease and developing targeted therapies that can correct aberrant imprinting patterns. Similarly, ongoing research into cancer neuroscience aims to refine strategies for disrupting tumor-neuron communication and improving outcomes for patients with brain cancer. These advancements promise to reshape our understanding of both inherited diseases and the most challenging forms of cancer.
