Patent ID: 8575330

Claim:
A microRNA-based short hairpin RNA for gene silencing the genetic expression of NR1 subunit of N-methyl-D-aspartate receptor comprising: a single strand RNA fragment comprising a first fragment, a second fragment and a connecting fragment, wherein the first fragment and the second fragment are complementary to each other, and are spaced and connected by the connecting fragment, with the connecting fragment being randomly arranged nucleotides, with the first fragment having a Drosha recognized cleavage site, a silencing site and a Dicer recognized cleavage site, with the Drosha recognized cleavage site and the Dicer recognized cleavage site being spaced and connected by the silencing site, with the silencing site encoding homologous nucleotides corresponding to NR1 subunit of N-methyl-D-aspartate receptor, wherein the microRNA-based short hairpin RNA comprises a sequence as set forth in SEQ ID No: 6.
