Sabine Seeler: Do circular RNAs possess a functional role in the nervous system?
PhD defence, Thursday, 23 September 2021, Sabine Seeler
RNAs are essential biomolecules in the regulation of cellular processes both in physiological and pathological conditions. Despite the well-established role of messenger RNAs (mRNAs) as blueprint carrier for protein synthesis, the majority of RNAs in mammalian cells are considered non-coding RNAs (ncRNAs). These do not comprise encoded information for protein production, but can still harbor the potential to regulate gene expression and protein synthesis. Circular RNAs (circRNAs) are a recently discovered example of ncRNAs. In contrast to other ncRNA classes, such as micro RNAs, their role in mammalian brain development and neurodegenerative diseases is to a large extent undeciphered.
During her PhD studies, Sabine investigated the function of selected circRNAs in early mammalian brain development as well as characterized the circRNA profile in mammalian models recapitulating the neurodegenerative disease amyotrophic lateral sclerosis (ALS). From this work, a particular circular RNA influencing neural development of mammalian model systems was discovered. Additionally, the studies shed light on alterations of the circular expression profile in ALS models. Her research findings contribute to the discussion on whether circRNAs could possess regulatory functions in the nervous system.
The PhD study was completed at the Interdisciplinary Nanoscience Center (iNANO) and Department of Molecular Biology and Genetics, Faculty of Natural Sciences, Aarhus University.
