MicroRNA leading to major depression discovered
US-based researchers have discovered that patients with major depressive disorder (MDD) have elevated levels of a microRNA, named miR-124-3p, in their brains' prefrontal cortex, the part critical for responding to stress. The mental disease, which affects around 250 million people every year, increases suicidal risks and is reported to cause the second-most years of disability after low-back pain.
