Abstract
Objective Calcium voltage-gated channel subunit alpha1 C (CACNA1C) plays a critical role in many vascular physiological and pathological processes. Determining its tissue-specific expression pattern and clarifying the underlying molecular mechanisms are necessary and meaningful. Methods We selected several representative vessels from normal male Sprague-Dawley rats. Vessel tissue or primary vascular smooth muscle cells were isolated for vascular function, electrophysiology, gene expression and promoter methylation studies. Results We found CACNA1C had tissue-specific expressions in vessels. The specific manifestations were as follows: CACNA1C expression was highest in thoracic aorta, second lowest in middle cerebral and pulmonary artery, and lowest in mesenteric artery. Excitingly, an opposing trend was observed between CACNA1C expression and its promoter methylation. Conclusions This study was the first report to indicate that DNA methylation could be involved in regulating CACNA1C tissue-specific expressions and vasoconstriction function in vascular system. This study not only provided more information for further understanding the physiological characteristics of vascular CACNA1C expressions, also strengthened the idea that DNA methylation plays important roles in regulating vascular smooth muscle cells function and the consequent occurrence of vascular diseases.

Abstract
Vascular calcification (VC) is the abnormal deposition of calcium, phosphorus, and other minerals in the vessel wall and can be commonly observed in diabetes, chronic kidney disease, and chronic inflammatory disease. It is closely associated with mortality from cardiovascular events. Traditionally, calcification is considered as a degenerative disease associated with the aging process, while increasing evidence has shown that the occurrence and development of calcification is an active biological process, which is highly regulated by multiple factors. The molecular mechanisms of VC have not yet been fully elucidated. Exosomes, as important transporters of substance transport and intercellular communication, have been shown to participate in VC. The regulation of VC by exosomes involves a number of complex biological processes, which occur through a variety of interaction mechanisms. However, the specific role and mechanism of exosomes in the process of VC are still not fully understood and require further study. This review will briefly describe the roles of exosomes in the process of VC including in the promotion of extracellular mineral deposits, induction of phenotypic conversion of vascular smooth muscle cells (VSMCs), transport of microRNA between cells, and regulation on autophagy and oxidative stress, with the aim of providing novel ideas for the clinical diagnosis and treatment of VC.
