Abstract
We aimed to investigate the mechanisms of Brahma related gene 1 (BRG1) in promoting vascular calcification in chronic kidney disease (CKD). The expression of BRG1 was examined in high phosphorus stimulated rat aortic smooth muscle cells (RASMCs) and calcified artery tissues from rat models and hemodialysis patients. Autophagosome formation was measured in high phosphorus stimulated RASMCs with and without BRG1 knock-down. We also detected the coexistence of BGR1 and exosomes, and measured the circulatory levels of BRG1 in the hemodialysis patients. BRG1 promoted the osteogenic transdifferentiation of RASMCs. Silencing BRG1 prevented autophagy from being induced by high phosphorus stimulation in RASMCs. Increased expression of BRG1 was observed in calcified blood vessels. Serum BRG1 level increased in the hemodialysis patients. BRG1 was involved in the development of high phosphorus induced osteogenic phenotype invitro and invivo, and its underlying mechanism might be facilitating autophagy.
