Elucidating Molecule-Crosstalk of Neutrophil Extracellular Traps Between Cardiovascular Disease and Psoriasis: Insights Into Mendelian Randomization, Single-Cell RNA Analysis, Shared Targets and the Role of Resveratrol.

BACKGROUND

Left ventricular hypertrophy (LVH) associated with hypertension and psoriasis (PSO) are linked by poor prognosis. Neutrophil extracellular traps (NETs) are implicated in both conditions, but the mechanisms remain unclear.

METHODS

We integrated bulk and single-cell RNA sequencing, mendelian randomization, immune microenvironment analysis, and molecular docking to explore the molecular interactions between LVH and PSO, focusing on NET-related pathways. Prediction models were also developed, and gene function was validated through in vivo and in vitro experiments.

RESULTS

Our findings identified NETs-associated genes, AKT serine/threonine kinase 1 (), and receptor-interacting protein kinase 1 (), regulating inflammation, fibroblast activation, and apoptosis in LVH and PSO. Functional enrichment analysis revealed mitochondrial metabolic disorders and extensive inflammation as the most prominent shared features of LVH and PSO diseases. Additionally, resveratrol exhibited a high binding affinity to the AKT1 and RIPK1 proteins. Functional validation showed that knockdown of AKT1 reduced LVH cell hypertrophy and PSO cell apoptosis.

CONCLUSION

This study highlights molecular pathways linking LVH and PSO, suggesting novel targets for treating cardiac involvement in PSO patients with LVH.
