Research Overview

Dr Pekovic-Vaughan's laboratory is pursuing an interdisciplinary research programme at the interface between molecular medicine, circadian physiology and systems biology, and elucidating biological mechanisms from molecules and cells to whole organisms and system-level network modelling. We are investigating the feedback interactions between circadian rhythms, a timing mechanism present in all cells, and diverse cellular signalling pathways in the regulation of normal physiological processes ranging from stem cell differentiation to cellular responses to stress and transcriptional gene regulation.

Discovering basic molecular mechanisms is critical in building our understanding of how circadian redox misalignments contribute to many chronic age-related conditions we study in our group (e.g. sarcopenia, lung fibrosis, chronic wounds, cardiac disease) and human inherited diseases (e.g. Collagen VI myopathies, Laminopathies, Peripheral neuropathies, Systemic Sclerosis, Marfan Syndrome and Fabry Disease). We wish to uncover how ageing and various chronic conditions (e.g. shift work or disease) impact tissue repair and responses to injury/stress, and how these processes can be modulated by chrono-therapeutic approaches (both pharmacological or non-pharmacological such as diet and exercise) in order to improve tissue resilience and delay precocious tissue atrophy, scarring or degeneration.

We are actively investigating the translational potential of utilizing chronotherapy in smarter drug repurposing (e.g. antiviral candidates in post-COVID, novel retinoic acid based candidates for neuromuscular ageing).

We employ a wide range of state-of-the-art molecular, cellular, biochemical, bioinformatic and in vivo approaches, including advanced molecular biology tools, transgenic clock-reporter mice, real-time bioluminescence imaging, ‘omic’ profiling approaches (RNAseq, proteomics, metabolomics) and epigenetics (ATACseq, ChiPseq).

The research programme in Dr Pekovic-Vaughan's group’s is funded through UKRI (MRC, BBSRC, EPSRC), Welcome Trust, RoseTrees Trust, Muscular Dystrophy (MD) UK, Dowager Eleanor Peel Trust, Age UK, Newton Fund, The Royal Society and CIMA (MRC/Versus Arthritis).
