Hickson Group

The main focus of the Hickson Group is to define how chromosomal instability over a human life-course influences the aging process and age-associated pathologies such as cancer and neurodegenerative disorders

Image Legend: Examples of chromosome segregation errors that arise in DNA repair defective cells during the process of cell division (mitosis). The yellow arrows mark two types of these errors: a DNA bridge (center) and lagging chromosomes (right). The image on the left shows a normal mitosis. DNA was stained with a dye and is shown in grey.




The Hickson Group utilizes cutting-edge molecular/cell biology techniques, coupled with innovative biophysical methods to understand the molecular basis of the aging process. The aim is to identify how changes to chromosome structure and integrity impact on the fitness of human cells and their longevity.

“Our ultimate aim is to be able to design interventions that will have a positive impact on the health-span of individuals”, says Professor and Group Leader Ian Hickson.

The group has world-leading expertise in the study of how chromosome integrity is maintained in human cells. This has permitted the group to define the molecular basis of selected genetic disorders that are associated with premature aging and/or an increased incidence of age-associated disease. Together with partners in the University of Copenhagen and Center for Chromosome Stability, the group seeks to understand ways in which chromosome instability can be minimized and/or prevented.







The role of folate deficiency in the development of age-associated human disease. Together with our collaborator, Associate professor Ying Liu, the Hickson Group investigates the link between folate deprivation, chromosome maintenance and the development of neurological disorders. Dietary folate deficiency is common in the elderly because of reduced intake and poor intestinal absorption. The group seeks to define new biomarkers of defective genome maintenance associated with folate deprivation
