HSPA8 and depressive symptom measurement: MiRNAs (e.g. miR-26b-5p, miR-377-3p), genes (TNRC6B, HSPA8), and pathways (FoxO- and Hippo-signaling pathway) are identified which could be mediators between the influence of depression on bone health and could possibly serve as biomarkers in the treatment of bone diseases among people with mental disorders.
