Intergenerational Inheritance of Nutritional States
How does parental diet impact the health of future offspring? This is one of the many questions the laboratory of Dr. Adelheid (Heidi) Lempradl seeks to answer. With mounting evidence that nutrition and metabolism can have a ripple effect through the generations, it is critically important to gain a better understanding of how these processes work in order to develop interventions that improve human health.
By determining the molecular mechanisms that underlie phenotype transmission across generations, the Lempradl Laboratory aims to identify and systematically map the nutritional and chemical sources of adverse intergenerational effects. Their ultimate goal is to develop novel ways to prevent transmission of harmful phenotypes to subsequent generations and thus, in the long term, improving health.
Dr. Lempradl and her colleagues were the first to show that paternal diet reprograms metabolism of the offspring in Drosophila. Their findings also identified one of the first gene networks required for proper intergenerational metabolic programming. Additionally, they identified the first epigenetic signature associated with obesity that is conserved across species, firmly establishing Drosophila as a valuable model in the field of intergenerational inheritance.
Her earlier work also resulted in major advances in the understanding of how DNA regulatory elements control gene expression. In 2014, she and her colleagues published novel evidence that strand-specific RNA transcripts act as a key developmental switch for regulatory elements, representing a simple and elegant system for enabling highly complex temporal and spatial gene regulation in development.
Register for the EMBO Workshop
The fundamental question of the role of metabolism in development has seen a revival in interest. Recent work revealed the intricate relationship between energy flux, spatial and temporal control of metabolites, the environment and embryogenesis. Currently, researchers engaged in the field lack a common platform. The workshop “Developmental Metabolism- flows of energy, matter, and information” will create an intellectual space to exchange ideas across disciplines and help form a vibrant, diverse community at the interphase between developmental biology, molecular metabolism, mathematics and physics.

Assistant Professor, Department of Metabolism and Nutritional Programming
Areas of Expertise
Epigenetics, metabolism, intergenerational inheritance, nutritional programming
Dr. Adelheid (Heidi) Lempradl is an assistant professor in Van Andel Institute’s Metabolic and Nutritional Programming group, where she investigates how the parental metabolic state is transmitted through generations. She earned her diploma and her Ph.D. from University of Vienna, where she used fluorescent probes to study the structure and folding of lipid membranes and RNAs. She continued her RNA work as a postdoctoral fellow in the lab of Dr. Leonie Ringrose at University of Austria, followed by a fellowship in the lab of Dr. Asifa Akhtar at Max Planck Institute of Immunology and Epigenetics in Freiburg, Germany. Most recently, she was a fellow in the lab of Dr. J. Andrew Pospisilik, also at Max Planck. Her research was the first to demonstrate that acute paternal diet of Drosophila can reprogram offspring metabolism. This work also identified the first epigenetic signature of obesity that is conserved across species, which established the value of Drosophila as a model for intergenerational inheritance. She was the recipient of the 2002 DOC-fFORTE Ph.D. Fellowship from the Austrian Academy of Sciences, was nominated for the Helmholtz Young Investigator Diabetes (HelDi) Award in 2018, and has given invited talks at numerous meetings and symposia, including the keynote address at the SETAC/iEOS Joint Topic Meeting on Environmental and (Eco) Toxicological Omics and Epigenetics.
