Role of long non-coding RNAs in depression: Mechanisms and potential therapeutic targets

Depression, also known as major depressive disorder, is a mental disorder caused by multiple factors. The cause of depression remains unclear, but a growing number of studies have reported a link between depression and long non-coding RNAs (lncRNAs). In the present study, we reviewed the relationships between depression and four lncRNAs, focusing on the differential expression of these lncRNAs in patients with depression, how to regulate depression, and how to use lncRNAs for the diagnosis, prevention, and treatment of clinical depression. A systematic review of 23 studies published between 2011 and 2021 was conducted using Pubmed. Selection criteria included publication date and relevance to topic: Only articles published after 2010 were included to ensure the review reflects the most recent research, and all articles are selected strictly on their research topic. The short communication has summarized the relationships between depression and four lncRNAs, especially antisense lncRNAs and lincRNAs, and their potential in the diagnosis of depression and its targeted therapy. The study found that these four lncRNAs, particularly antisense lncRNAs and lincRNAs, are closely associated with various aspects of depression. These findings suggest new therapeutic targets and could contribute to improving the accuracy of depression diagnosis.
