A high coronary artery calcification score (CACS) may be associated with mortality in patients undergoing hemodialysis (HD). Recently, effects of iron on vascular smooth muscle cell calcificat...
Tumor vessels often lack the smooth muscle layer, and the instability is conducive to tumor invasion and metastasis. The effect of tumor microenvironment on vascular smooth muscle cells needs to be explored. In the present study, we examined the density of the tumor vessels in human colorectal cancer tissues, and used the tumor conditioned medium of human colorectal cancer HT29 cells to mimic t...
Background: Hindlimb Unloading (HLU) is used to simulate microgravity in rats and has been shown to decrease contractile response in the abdominal aorta. The aim of present study was to investigate the contractile responses of smooth muscle of thoracic aorta following acute and chronic microgravity treatment. Methods: Male adult rats (Wistar) were subjected to HLU for 3 and 20 days t...
Many vasoactive agents stimulate release of an endothelium-derived relaxing factor (EDRF). EDRF stimulates cyclic guanosine 3',5'-monophosphate (cGMP) accumulation and relaxation of vascular smooth muscle in a manner similar to that produced by sodium nitroprusside. Endothelium and vascular smooth muscle were isolated from porcine, bovine, and rat thoracic aorta. The capacity of sodium nitropru...
In this study, we compared the potencies of diosgenin, a plant-derived sapogenin structurally similar to estrogen and progesterone, on vascular smooth muscle functions ranging from contraction and migration to apoptosis. The effects of diosgenin on vascular smooth muscle cell viability and migration were measured using a primary mouse aortic smooth muscle cell culture. The effects of diosgenin ...
Details of the interdependent, trophic relation between smooth muscle and its neural innervation are not well known despite suggestions that neural influences may contribute significantly to hypertensive and other cardiovascular disease. Vascular smooth muscle is a major target of innervation by neurons of the sympathetic nervous system. Sympathetic neurons depend on a constant supply of the po...
RATIONALE Vascular smooth muscle turnover has important implications for blood vessel repair and for the development of cardiovascular diseases, yet lack of specific transgenic animal models has prevented it's in vivo analysis. OBJECTIVE The objective of this study was to characterize the dynamics and mechanisms of vascular smooth muscle turnover from the earliest stages of embryonic developm...
