摘要

Cardiometabolic diseases remain a major global health burden, and current therapies only partially address the persistent residual risk driven by chronic inflammation, hypoxia, metabolic overload, and mechanical stress. A critical need is to understand how these diverse stress signals are integrated at the cellular and molecular levels to determine whether tissues adapt or undergo pathological remodeling. This review presents a comprehensive framework of kinase-microRNA (miRNA) crosstalk as an emerging regulatory axis in cardiometabolic disease. We discuss how stress-activated kinase pathways, including ERK, p38/JNK, PI3K-Akt-mTOR/S6K2, AMPK, GSK-3, and EGFR, reprogram miRNA output through phosphorylation of key components of the miRNA machinery, including DROSHA/DGCR8, DICER-TRBP, and AGO2. These phosphorylation-dependent mechanisms influence miRNA processing, substrate selection, RISC assembly, and target repression in a context-dependent manner. We further highlight the reciprocal regulation whereby miRNAs modulate kinase signaling pathways, establishing feedback networks that regulate inflammation, apoptosis, fibrosis, angiogenesis, and metabolic adaptation across cardiac, vascular, and immune cells. Emerging technologies, including AGO2 eCLIP, phosphoproteomics, CRISPR-based perturbations, and single-cell/spatial profiling, allow causal mapping of kinase-miRNA networks. Collectively, these advances establish kinase-miRNA crosstalk as a promising mechanistic framework and therapeutic target for precision intervention in heart failure, atherosclerosis, diabetic cardiomyopathy, and related cardiometabolic diseases.
