RESUMO
Nogo protein is the fourth member of reticulin famity. Nogo mRNA produced by encoding gene transcription, forms three different RNA transcripts due to different promoter and splicing modes, namely Nogo-A, Nogo-B and Nogo-C protein. Nogo protein was first found in the central nervous system, and then proved to be widely expressed in peripheral tissues such as heart, liver and vascular endothelium. Studies have shown that Nogo protein can participate in the regulation of myocardial fibrosis through RhoA/Rho-associated kinase(ROCK) pathway, endoplasmic reticulum stress, Sce61 a and other signaling pathways. In this paper, the relationship between Nogo-A, Nogo-B, Nogo-C and myocardial fibrosis is briefly introduced.
RESUMO
As a member of the reticulin family, Nogo is mainly involved in processes such as tissue regeneration, apoptosis and tumor growth after tissue injury. Cardiovascular disease is one of the main diseases that threaten human health at present. In recent years, research on Nogo in the cardiovascular system has become increasingly extensive. Changes in the expression of Nogo during myocardial fibrosis, myocardial cell apoptosis and vascular remodeling suggest that it may play a certain role. This article reviews the distribution of Nogo in the heart and its role in cardiovascular disease, in order to reveal its possible role and mechanism in cardiovascular diseases.
