MicroRNA Dynamics in Cardiovascular Disease
Summary
MicroRNAs (miRNAs) are short non-coding RNAs that regulate gene expression at the post-transcriptional level. In cardiovascular disease, dynamic changes in cellular and circulating miRNA profiles influence key processes including cardiomyocyte hypertrophy, fibrosis, angiogenesis and inflammatory responses. Alterations in miRNA biogenesis and turnover can modulate signalling pathways such as TGF-β, PI3K/AKT and Wnt, thereby affecting cardiac remodelling following injury. In atherosclerosis, endothelial and smooth muscle cell-derived miRNAs contribute to plaque stability, lipid handling and vascular inflammation. Circulating miRNAs, released via exosomes or protein complexes, offer non-invasive biomarkers for diagnosis, prognosis and disease stratification. Recent advances have refined delivery platforms and molecular inhibitors or mimics to target specific miRNAs, opening new avenues for precision therapeutics in conditions such as heart failure, cardiomyopathies and ischaemia-reperfusion injury. This expanding field is underpinned by global efforts to integrate miRNA signatures with existing clinical markers, emphasising translational potential for patient care.
Research from Nature Portfolio
Recent studies have demonstrated the therapeutic potential of targeting miR-132 to mitigate adverse cardiac remodelling. An optimised, locked nucleic acid-based antisense inhibitor of miR-132 showed dose-dependent efficacy and safety in preclinical models of heart failure, including a translationally relevant pig model. Pharmacokinetic analyses revealed favourable tissue distribution and tolerability, while functional assessments confirmed reversal of pathological cardiomyocyte growth and improved cardiac output. These findings underscore the promise of miRNA-directed therapies to address unmet needs in heart failure management by intervening at the molecular drivers of disease progression.
MicroRNA Dynamics in Cardiovascular Disease publication trend
The graph below shows the total number of articles in microrna dynamics in cardiovascular disease across all publications each year (not limited to Nature Index journals).
Technical terms
MicroRNA (miRNA): Short, non-coding RNA molecules (∼22 nucleotides) that repress target mRNA translation or induce degradation.
Antisense inhibitor (antimiR): A synthetic oligonucleotide designed to bind and inhibit a specific miRNA, preventing its interaction with target mRNAs.
Dilated cardiomyopathy: A disease characterised by dilatation and impaired contraction of the left or both ventricles, leading to heart failure.
Ubiquitin-proteasome system (UPS): A cellular pathway for protein degradation in which ubiquitin tags target proteins for proteasomal breakdown, maintaining protein homeostasis.
