Project description
Carbon monoxide and viscosity monitoring in live cells
Carbon monoxide (CO) is an endogenous gasotransmitter, associated with cytoprotection and cellular homeostasis. Increased enzymatic generation of CO plays a critical role in the resolution of inflammatory processes and alleviation of cardiovascular disorders. The changes in cellular viscosity have been linked to inflammation, including in cardiovascular disease. The diffusion-controlled movement of cellular carbon monoxide is affected by the viscosity changes. The EU-funded COVISENSE project aims to carry out simultaneous measurement of carbon monoxide and cellular viscosity linked to the state of inflammation and disease. The researchers will introduce novel bimetallic ruthenium molecular probes capable of monitoring both endogenous carbon monoxide and the viscosity in the cellular environment.
Objective
Despite its toxic reputation, carbon monoxide (CO) is also an important biological messenger molecule that regulates many vital cell processes, including the response to disease. Increased enzymatic generation of carbon monoxide plays a critical role in the resolution of inflammatory processes and alleviation of cardiovascular disorders. At the same time, altered viscosity levels have been associated with inflammation, including in cardiovascular disease. Since the diffusion-controlled movement of carbon monoxide is also affected by changes in the viscosity of the cellular environment, the two aspects are intimately connected. Therefore, the simultaneous measurement of both carbon monoxide and cellular viscosity would provide unprecedented information on the functioning of the cell and the state of inflammation and disease. We propose to achieve this through a new family of bimetallic ruthenium(II) molecular probes capable of monitoring both endogenous carbon monoxide (using fluorescence intensity) and the viscosity in the cellular environment (through fluorescence lifetime). These highly selective probes would show very low detection limits for CO and operate within the ‘biological window’ above 650 nm. At the same time, internal rotation of the BODIPY fluorophore would allow fluorescence lifetime imaging microscopy (FLIM) to be used to monitor the local viscosity. Through a collaboration with immune-oncologists, the probes will be used to expand the understanding of the role played by the enzyme, haem oxygenase (HO-1), that produces CO. This could help illuminate the association between HO-1 expression and poor prognosis in cancer patients. The project will combine ligand design, organometallic synthesis, fluorescence imaging and cell work, providing the opportunity to gain experience in a range of areas related to sensing in biological environments.
