Although transcriptional pathways that control exercise-based plasticity have been studied in depth, recent findings highlight the importance of microRNAs (miRNAs) as an essential post-transcriptional control platform mediating contractile stimuli and molecular and physiologic adaptations. This review provides a synthesis of existing evidence on exercise responsive miRNAs at the systems level, and especially on the topic of skeletal muscle remodeling. The review outlines the effects of different exercise regimens such as endurance, resistance, and high-intensity interval training to dynamic miRNA response to regulate major biological pathways such as mitochondrial biogenesis, protein turnover, angiogenesis, inflammatory signaling, and metabolic regulation. Acute exercise is also typified by temporary changes in miRNAs, which facilitate short-term stress signalling, and chronic training leads to more long-term miRNA re-programming, which facilitates long-term structural and functional remodeling. Also, circulating and exosome-bound miRNAs are also mentioned as potential agents of the muscle-to-organ interaction, thus supporting the idea of skeletal muscle that acts like an endocrine-like organ during exercise. Besides narrative synthesis, the review is based on an exploratory, data-driven re-analysis of publicly available skeletal muscle miRNA sequencing data to define convergent regulatory programs instead of data-specific differentiation. This is observed under integrative pathway and network-level analysis which identifies coordinated miRNA modules linked to mitochondrial regulation, cytoskeletal remodeling, and inflammatory control. Taken together, this framework brings together non-homogenous evidence throughout the literature and highlights the prospect of exercise-sensitive miRNAs as systems-level regulators of skeletal muscle adaptation.</p>","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":"478 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hallmark of hypertension is elevated total peripheral vascular resistance, often driven by sustained and abnormal vasoconstriction. Calcium ions (Ca²⁺) play a central role in vascular smooth muscle cell (VSMC) contraction, and their intracellular concentration is tightly regulated by multiple signaling pathways. Among these, the inositol 1,4,5-trisphosphate receptor (IP<sub>3</sub>R) and the transient receptor potential canonical type 3 (TRPC3) channel are critical mediators of Ca²⁺ signaling. IP<sub>3</sub>R activation triggers Ca²⁺ release from the endoplasmic reticulum, while TRPC3 channels facilitate Ca²⁺ and Na⁺ influx across the plasma membrane. Several studies have shown that both IP<sub>3</sub>Rs and TRPC3 channels are upregulated in hypertensive animal models. Human studies have also demonstrated elevated TRPC3 expression in the context of pulmonary arterial hypertension (PAH). This review provides a comprehensive overview of the structural domains and membrane microdomains that facilitate IP<sub>3</sub>R-TRPC3 coupling and Ca²⁺ influx. IP₃ and endothelin-1 stimulate TRPC3 channels and promote their molecular coupling to IP<sub>3</sub>Rs, leading to activation of nonselective cation currents in artery myocytes. Increased expression and/or activity of IP<sub>3</sub>Rs and TRPC3 channels amplifies this signaling, contributing to the increased vascular tone characteristic of the hypertensive state. Understanding the molecular interplay between IP<sub>3</sub>Rs and TRPC3 channels offers new insight into the dysregulated Ca²⁺ signaling underlying hypertension. Targeting this coupling mechanism may represent a novel therapeutic strategy to restore vascular homeostasis and reduce blood pressure in affected individuals.</p>","PeriodicalId":19954,"journal":{"name":"Pflugers Archiv : European journal of physiology","volume":"478 5","pages":""},"PeriodicalIF":2.9,"publicationDate":"2026-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13135602/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147819509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
