The Sibon’s group focus is to understand Coenzyme A metabolism in health and disease. Coenzyme A is a central metabolic cofactor, known for over 60 years. In recent years, the awareness is increasing that Coenzyme A, in addition to its essential role in metabolism also plays a role in signal transduction, ageing, epigenetics and neurodegeneration.

The current view is that cells obtain their Coenzyme A via a de novo biosynthesis pathway starting with the uptake of vitamin B5. Recently the Sibon group showed that cells and organisms can also take up Coenzyme A from external sources. The mechanism behind this newly discovered manner of obtaining Coenzyme A is under investigation. The presence of this alternative route of intracellular Coenzyme A is of high importance for subjects suffering from inborn genetic errors of impaired Coenzyme A de novo biosynthesis, resulting in severe neurodegenerative diseases. Findings obtained in model organisms are being explored how to use external supplies of Coenzyme A to develop therapies for these diseases.
Ody C.M. Sibon received her PhD in 1994 in Molecular Cell Biology at the University of Utrecht, The Netherlands. She studied the topological organization of transcription and splicing at the ultrastructural level under the supervision of Prof. A.J. Verkleij. She then moved to the United States, were she studied the role of DNA checkpoint regulation during early embryonal development in Drosophila melanogaster at the University of Stoney brook, NY. Her postdoctoral advisor was prof. W.E. Theurkauf.
In 1998 she moved to the University of Groningen, the Netherlands were she started her own group. In 2002 she received a VIDI grant and in 2011 a VICI grant, both from the Dutch organization for Scientific research. Her research now is focussed on understanding the mechanisms of an altered Coenzyme A uptake route and the possibilities of this route in health and disease. She is named as inventor on several patents based on her discoveries related to Coenzyme A metabolism and she is developing these further towards therapies for Coenzyme A-related diseases. In 2009 she became a full professor. She is partner and/or coordinator of several European, American and Dutch grants.
