More significantly, many studies have shown that there are complementary sequences among miR-494-3p, miR-30a-5p, miR-7, and miR-210-3p and BDNF [59, 61–63], suggesting that interfering with the expression of these miRNAs could be a strategy for BDNF regulation in PD pathogenesis. The gene discussed is BDNF; the disease is Parkinson disease.
