Drug discovery and cell therapy in cardiovascular diseases
Dr. Motterlini’s laboratory has a long-standing interest in the biological significance of heme oxygenase-1 (HO-1), a ubiquitous defensive protein that degrades heme to carbon monoxide (CO), biliverdin and bilirubin (see Figure 1) .
Together with Dr. Roberta Foresti, their team has extensively contributed to understand how HO-1 and endogenous bilirubin and CO render vascular and cardiac tissues more resistant to oxidative stress and injury [2-7].
Within the frame of our research strategies, we have also worked extensively on the identification of small molecules that specifically target the HO-1/CO pathway for the implementation of new pharmacological approaches to treat cardiac disorders and inflammation.
Notably, this work led to the pioneering discovery and characterization of CO-releasing molecules (CO-RMs), compounds that deliver controlled amounts of CO to tissues (see Figure 2) [8-10].
Several studies by our group, which have been corroborated by other laboratories, have confirmed that CO-RMs are pharmacologically active by exerting vasodilatory, anti-ischemic, anti-inflammatory and bactericidal effects in vitro and in animal models of disease [11-17].
As the intracellular target(s) of CO remains elusive, part of our research plan is now to investigate the mechanism of action of CO with particular emphasis on the effect of CO-RMs on redox signaling and mitochondrial bioenergetics .
In parallel, we are also working on the design and synthesis of effective small molecules that induce HO-1 by targeting the transcription factor Nrf2 which controls HO-1 gene expression (see Figure 2). This is based on our original findings that curcumin and other natural compounds strongly induce HO-1 protein expression and activity via transcriptional regulation of Nrf2 [19-25].
The recent synthesis of “HYCOs”, novel hybrid molecules able to activate the Nrf2/HO-1 axis and simultaneously release CO, is an example of our drug discovery approach . As part of these projects, which are conducted in collaboration with a chemistry group (Dr. Michael Rivard), the team aims to investigate in depth the mechanism(s) of action by which HO-1 and CO exert its pharmacological effects by modulating mitochondrial function, metabolism and inflammation.
Complementary to our drug discovery approach, the team relies on the expertise of Dr. Anne Marie Rodriguez in stem cell therapy for cardiac and tissue regeneration. Dr. Rodriguez contributed over the years to understand how stem cells exert their protective effects on injured cardiomyocytes. Her studies showed that communication between mesenchymal stem cells (MSC) and suffering cardiomyocytes via formation of nanotubules is crucial for promoting the activation of cardioprotective factors secreted by MSC, leading to an increase in their angiogenic and chemoattractant functions and consequently aiding the regenerative process [27; 28]. Dr. Rodriguez is investigating protective pathways in the repairing and rejuvenating capacities of stem cells, with particular emphasis on HO-1/CO as a therapeutic target.
The team is also investigating approaches that combine the use of CO-RMs and HYCOs with stem cell technologies (see Figure 2).
