The role of the ER stress sensor IRE1 in cardiovascular diseases.
Despite enormous advances in the treatment of cardiovascular diseases, including I/R injury and heart failure, heart diseases remain a leading cause of mortality worldwide. Inositol-requiring enzyme 1 (IRE1) is an evolutionarily conserved sensor endoplasmic reticulum (ER) transmembrane protein that senses ER stress. It manages ER stress induced by the accumulation of unfolded/misfolded proteins via the unfolded protein response (UPR). However, if the stress still persists, the UPR pathways are activated and induce cell death. Emerging evidence shows that, beyond the UPR, IRE1 participates in the progression of cardiovascular diseases by regulating inflammation levels, immunity, and lipid metabolism. Here, we summarize the recent findings and discuss the potential therapeutic effects of IRE1 in the treatment of cardiovascular diseases.
期刊介绍：
Molecular and Cellular Biochemistry: An International Journal for Chemical Biology in Health and Disease publishes original research papers and short communications in all areas of the biochemical sciences, emphasizing novel findings relevant to the biochemical basis of cellular function and disease processes, as well as the mechanics of action of hormones and chemical agents. Coverage includes membrane transport, receptor mechanism, immune response, secretory processes, and cytoskeletal function, as well as biochemical structure-function relationships in the cell.
In addition to the reports of original research, the journal publishes state of the art reviews. Specific subjects covered by Molecular and Cellular Biochemistry include cellular metabolism, cellular pathophysiology, enzymology, ion transport, lipid biochemistry, membrane biochemistry, molecular biology, nuclear structure and function, and protein chemistry.
