However, it is worth noting that the expression of ribosomal proteins RPL17 and RPL34 in the blood samples of patients with depression has been reported to be up-regulated (47), indicating that the changes in the expression level of each member of the ribosomal protein family in the disease are not completely consistent, and the changes in the expression level of RPS7 in myocardial infarction and depression need further confirmation. Here, RPL34 is linked to major depressive disorder.
