Li et al. (2013) measured serum BDNF, miR-132, and miR-182 mRNA levels in 40 depressed patients versus 40 healthy controls, reporting lower BDNF levels in association with depression, whereas the levels of miR-132 and miR-182 were significantly increased (Li et al. 2013). The gene discussed is BDNF; the disease is depressive symptom measurement.
