Research Interests

Dr Ricketts’s research program is in the areas of molecular nutrition and endocrinology. Her work mainly focuses on understanding the molecular mechanisms underlying the metabolic effects of bioactive dietary constituents/natural products, with an emphasis on the role played by nuclear hormone receptors (NHRs). NHRs are ligand-inducible transcription factors that regulate gene expression by interacting with specific DNA sequences upstream of their target genes, and they are involved in key biological processes including development, reproduction, metabolism, cell growth, differentiation and immunity. Dr Ricketts has extensive experience in elucidating molecular mechanisms of action of bioactive dietary components, e.g. cafestol which acts as an agonist ligand for the farnesoid x receptor and pregnane x receptor to increase serum cholesterol levels. Dr Ricketts has also undertaken research studies regarding nuclear hormone receptor-mediated actions of soy isoflavones. Currently her work focusses on elucidating the molecular mechanisms of action of a grape seed procyanidin extract (GSPE) in order to understand how it regulates triglyceride (TG) homeostasis.
