It was suggested that miR-15a-5p, let-7d-5p, miR-511-5p, and miR497a-5p, which target the two key post-traumatic stress disorder-related genes, FKBP5 and BDNF, were differentially modulated in the several brain regions of the post-traumatic stress disorder-related susceptible and resilient mice [51]. The gene discussed is FKBP5; the disease is post-traumatic stress disorder.
