Cardiovascular diseases (CVDs) remain a significant global health challenge, with many current treatments addressing symptoms rather than the genetic roots of these conditions. The advent of CRISPR-Cas9 technology has revolutionized genome editing, offering a transformative approach to targeting disease-causing mutations directly. This article examines the potential of CRISPR-Cas9 in the treatment of various CVDs, including atherosclerosis, arrhythmias, cardiomyopathies, hypertension, and Duchenne muscular dystrophy (DMD).

Nucleic acid nanostructures offer unique opportunities for biomedical applications due to their sequence-programmable structures and functions, which enable the design of complex responses to molecular cues. Control of the biological activity of therapeutic cargoes based on endogenous molecular signatures holds the potential to overcome major hurdles in translational research: cell specificity and off-target effects. Endogenous microRNAs (miRNAs) can be used to profile cell type and cell state, and are ideal inputs for RNA nanodevices.

Introduction: Duchenne muscular dystrophy (DMD) is a severe X-linked disorder characterized by progressive muscle weakness and eventual death due to cardiomyopathy or respiratory complications. Currently, there is no cure for DMD, with standard treatments primarily focusing on symptom management. Using immunosuppressive measures and optimized vector designs allows for gene therapies to better address the genetic cause of the disease.

For years, the treatment of many cardiomyopathies has been solely focused on symptom management. However, cardiomyopathies have a genetic substrate, and directing therapy towards the pathophysiology rather than the epiphenomenon of the disease may be a winning strategy. Gene therapy involves the insertion of genes or the modification of existing ones and their regulatory elements through strategies like gene replacement and gene editing.

Genome editing based on programmable nucleases and donor DNA constructs permits introducing specific base-pair changes and complete transgenes or live-cell reporter tags at predefined chromosomal positions. A crucial requirement for such versatile genome editing approaches is, however, the need to co-deliver in an effective, coordinated and non-cytotoxic manner all the required components into target cells. Here, adenoviral (AdV) and adeno-associated viral (AAV) vectors are investigated as delivery agents for, respectively, engineered CRISPR-Cas9 nucleases and donor DNA constructs prone to homologous recombination (HR) or homology-mediated end joining (HMEJ) processes.
