Pioneering ADHD researcher reveals biological pathways linking genes to behavior

Barbara Franke's groundbreaking work transforms understanding of neurodevelopmental disorders through innovative molecular approaches

2025-05-27

(Press-News.org) NIJMEGEN, The Netherlands, 27 May 2025 – In a comprehensive Genomic Press interview published today, Professor Barbara Franke unveils her remarkable scientific journey from an inquisitive child fascinated by nature to becoming one of the world's most influential researchers in biological psychiatry. The molecular psychiatrist at Radboud University has fundamentally transformed our understanding of how genetic variations lead to altered behavior in neurodevelopmental conditions, particularly ADHD.

From HeLa Cells to Human Behavior

Professor Franke's career trajectory took an unexpected turn during a practical session isolating DNA from HeLa cells. "I fell in love with molecular genetics," she recalls, describing how this pivotal moment shifted her focus from studying great apes in Africa to unraveling the molecular mysteries of human behavior. This transition ultimately led her to psychiatric genetics, where she found her true calling in addressing the controversial and misunderstood nature of ADHD.

With over 500 peer-reviewed publications, Professor Franke has established herself among the top 1% most cited scientists globally. Her work extends far beyond traditional gene identification, employing innovative approaches that bridge multiple scientific disciplines. "I am absolutely amazed at how much we can already learn about the biological pathways and brain-cellular substrates underlying psychiatric conditions using data science methods," she notes, while emphasizing the indispensable role of experimental validation.

Building Bridges Across Disciplines

Professor Franke's leadership in founding multiple international research consortia, including the International Multicentre persistent ADHD Collaboration (IMpACT) and the ECNP Network ADHD across the lifespan, demonstrates her commitment to collaborative science. As a founding member of the Psychiatric Genomics Consortium (PGC), she recognized early that advancing psychiatric genetics required unprecedented international cooperation.

Her research philosophy combines cutting-edge bioinformatics with experimental models ranging from fruit flies to human induced pluripotent stem cells. This multifaceted approach raises intriguing questions about how genetic variations translate into behavioral differences and whether understanding these mechanisms could lead to more personalized treatments for neurodevelopmental conditions.

A New Vision for Psychiatric Classification

Currently heading the Medical Neuroscience department at Radboud University Medical Center, Professor Franke harbors ambitious goals. "We still need a new nosology in psychiatry, and I want to contribute to that by identifying genes and pathways," she explains. Her recent venture into epigenetics research explores how environmental factors interact with genetic predispositions, potentially unlocking new avenues for prevention and intervention strategies.

The decorated Knight in the Order of the Netherlands Lion approaches her work with a philosophy captured by the German proverb she lives by: "Die Suppe wird nicht so heiß gegessen, wie sie gekocht wird" ("The soup is not eaten as hot as it is cooked"). This balanced perspective has enabled her to navigate complex scientific challenges while mentoring the next generation of researchers.

Impact Beyond the Laboratory

Professor Franke's influence extends beyond her scientific contributions. Her "jump first, think later" mentorship approach has empowered countless young scientists, particularly women, to seize opportunities in competitive research environments. This philosophy raises important questions about how scientific culture might evolve if more researchers embraced calculated risk-taking and rapid decision-making.

The interview reveals fascinating insights into Professor Franke's recent move to epigenetics, using advanced single-cell resolution techniques to study DNA modifications and transcriptomes. These cutting-edge approaches could potentially identify biomarkers for treatment response or reveal critical windows for intervention during brain development.

As psychiatric conditions continue to affect millions worldwide, Professor Franke's work offers hope for improved diagnosis and treatment. Her integration of molecular biology, neuroscience, and clinical psychiatry exemplifies the interdisciplinary approach needed to tackle complex brain disorders. The question remains: How quickly can these biological insights translate into tangible improvements in patient care?

Mitochondrial DNA mutation accumulation may not be a determining factor in aging

2025-05-27

Tsukuba, Japan—The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria are cell organelles that produce energy essential for life activities through oxidative phosphorylation (mitochondrial respiration), and mtDNA encodes a set of genes required for mitochondrial respiration. Previous research has led to the widely accepted hypothesis that the accumulation of multiple mutations in mtDNA with aging induces a decline in mitochondrial respiratory function, resulting in the "mitochondrial theory of aging." Nevertheless, whether the decrease in mitochondrial ...

Researchers unveil epigenetic mechanism of cold adaptation in rice

2025-05-27

Chinese researchers recently uncovered molecular evidence supporting Lamarckism—a long-debated theory from the early 19th century that acquired characteristics can be inherited. The evidence was revealed in a new study by scientists from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences, which deciphered the evolutionary patterns of cold adaptation during rice's northward expansion. The study was published on May 22 in Cell. Led by Prof. CAO Xiaofeng, the researchers demonstrated that DNA methylation—a form of epigenetic variation ...

Hitting the right notes to play music by ear

2025-05-27

Learning to play music by ear is challenging for most musicians, but research from a team at the University of Waterloo may help musicians-in-training find the right notes. The Waterloo team analyzed a range of YouTube videos that focused on learning music by ear and identified four simple ways music learning technology can better aid prospective musicians – helping people improve recall while listening, limiting playback to small chunks, identifying musical subsequences to memorize, and replaying notes indefinitely. “There ...

High-speed binary phase-engraved superpixels improve complex light modulation

2025-05-27

Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the application of lasers in diverse fields, such as optical communication, three-dimensional display, biomedical imaging, and astronomy. Yet, despite dazzling progress seen by applications of complex field modulation (CFM), improvements to technical capabilities such as accuracy, speed, and versatility remain highly in demand. Key to the overall performance of CFM technologies are spatial light modulators (SLMs): advanced devices that provide two-dimensional arrays of electronically addressable pixels whose optical properties can be independently controlled to ...

Burden of Memory Disorders and the Role of Traditional Medicine The growing global population of elderly individuals has led to a dramatic rise in chronic diseases, including neurocognitive disorders such as Alzheimer’s disease. These conditions, which are expected to affect over 150 million people worldwide by 2050, are marked by memory loss, impaired judgment, and cognitive decline. While pharmacological interventions exist, their limitations in accessibility, affordability, and side effect profiles have prompted the exploration of holistic approaches. This review emphasizes traditional ...

Study finds significant declines in maternal mental health across US

2025-05-27

A new study published in JAMA Internal Medicine reveals a concerning decline in self-reported mental health among mothers in the United States between 2016 and 2023. Conducted by researchers at the Columbia University Mailman School of Public Health, the study also found modest but measurable declines in self-reported physical health during the same period. This large-scale analysis examined data from 198,417 mothers who participated in the National Survey of Children’s Health (NSCH), a nationally representative annual survey of households with children aged 0–17. Most participating mothers were over age 30, and over half had a privately ...
